Also available is the junior version, which is smaller and less expensive.

Another reliable budget choice is the Winix 5500-2 — this inexpensive filter is designed for odor removal.

Most air purifiers are designed to remove particles like dust, pollen, and pet dander from your home. However, the technology that makes for a good allergy machine is not similar to what you’ll need to remove odor.

Odors are gas molecules smaller than 0.3 microns, and many are as small as 0.001 microns. This means that particle filters (HEPA filters) will not trap the gas molecules because they are too small.

So basically, almost all the air filters on the market will remove little or no odor from the air.

These are the products that eliminate odors:

• An air filter that contains a lot of activated carbon, which is very good at adsorbing odors
• An air filter with zeolite, which is a natural mineral that is very good at adsorbing things
• For very problematic odors, you can use an ozone generator — ozone is active oxygen that breaks up odors quickly — but ozone is dangerous to inhale — so this generator should only be used in vacant homes when necessary

Other filtration methods work more gradually:

• You can put bowls or satchels of activated carbon, zeolite, or binchotan in a room — these raw materials will slowly absorb odors over time
• You can grow indoor plants in a room — they will clean the air gradually — see the book How To Grow Fresh Air for more information

But, if you want to remove odors quickly, these are my filter recommendations:

The Most Effective Odor Filter: Healthmate HM-400

I recommend the Healthmate HM-400 as the most effective filter for removing indoor odors. This filter uses 15 pounds of activated carbon and zeolite to remove odors and gases. It also includes another HEPA filter certified to remove 99.97% of all particles in the air over 0.3 microns.

Many filters remove particles from the air but are ineffective at odor removal. The Healthmate HM-400 is designed to remove odors, chemicals, and gases from the air. It incorporates 15 pounds of activated carbon and zeolite into the filter media. The sheer size of this material allows this filter to remove odors from the air quickly.

The Healthmate is also one of the cheapest to run in the long term because the replaceable filter is designed to last five years (most air filters require annual filter media replacement).

These filters are made in Buffalo, New York, and come with a 5-year mechanical warranty.

I’ve tested the Healthmate HM-400 in my home using a TES Air Quality monitor. This monitor measures VOCs or “Volatile Organic Compounds”. Put simply — VOCs are all the odor-producing chemicals suspended in the air. In my few informal tests, I found that the Healthmate could remove all traces of smoke odors from a room in about 45 minutes. I will be conducting further tests in the coming months.

The Best Budget Air Filter For Odors

If you need a budget air filter, consider these reliable filters that you can find for under $300:

• Winix 5500-2 Air Purifier: this filter contains carbon granules for odor removal and also produces ions for odor reduction — Winix is a reliable filter brand that has been in business since 1973 — the filter costs about $180
• Winix NK105: A WiFi-enabled filter from Winix that also contains a carbon-filter element — costs about $220

Best For Removing Embedded Odors

If you need to remove stubborn odors such as deeply embedded cigarette odors, I recommend using an Ozone Generator. These generators produce ozone gas which permeates everything in a room and effectively eliminates any odors present.

These devices sell for about $70. Important note — an ozone generator should not be used as a general air filter. Ozone will damage your lungs. They should only be used for odor “emergencies” and when a house is vacant.

Schott Zwiesel Glassware

Schott Zwiesel is a German company known for glassware innovation since 1872. They create break-resistant, chip-resistant, and scratch-resistant stemware. The crystal glass has added titanium for strength and zirconium for crystal clarity, making it dishwasher safe.

I have their glassware at home — the pieces are versatile and can be used daily, yet they are elegant enough to use on special occasions. They are slightly expensive, but the investment is worth it.

Schott Zwiesel is available on Amazon.

Duralex Picardie Tumblers

Duralex has been manufacturing tempered glassware in France since 1929. Their Picardie Tumblers are known for lasting decades — they will bounce several times when dropped on the floor and survive without a crack. The tumblers can also withstand a sudden thermal shock — the temperate glass can go from -4° F to 212° F without breaking. This means they can be used to drink hot beverages. Duralex glasses are also lighter and more elegant than similar tempered glass products.

Duralex went into court-ordered liquidation bankruptcy in 2006 but has since partnered with Emile Henry, an old French manufacturer of cooking ware, to return to production.

Duralex doesn’t offer any product warranty beyond a 21-day return policy. However, we found no tempered glass tumblers with an extended warranty.

Durlaex Tumblers are available from Amazon for about $18 for a set of six.

Fortessa Fortaluxe Vitrified Dinnerware

Fortessa is a dinnerware company line created by the German company Schott Zwiesel. Fortessa specializes in vitrified china dinnerware. The china is reinforced with alumina or magnesium oxide for durability and thermal shock resistance. The dinnerware is called Fortaluxe SuperWhite, and it is used in many restaurants around the world and is reasonably priced.

You can find Fortessa dinnerware on Amazon.

Pyrex Bowls

Pyrex is another brand of tempered glass products renowned for their durability. The Pyrex brand was introduced by Corning Incorporated in 1915. Today, Pyrex is owned by World Kitchen and Pyrex glass products are manufactured in Charleroi, Pennsylvania. Recently, there have been rumors circulating about Pyrex products. The rumors suggest that Pyrex products are made with inferior materials, prone to breakage, and manufactured in China. However, this lengthy article on the myth-busting website Snopes.Com, concludes that the rumors are false. Here is an excerpt from the article:

While it is literally true that the material used in manufacturing Pyrex brand glass bakeware has changed from borosilicate glass to soda lime glass, the brand’s current owner, World Kitchen, claims that changeover began back in the 1940s and long antedates Corning’s 1998 sale of the brand, stating that “The Charleroi [Pennsylvania] plant has produced PYREX glass products out of a heat-strengthened (tempered) soda lime glass for about 60 years, first by our predecessor Corning Incorporated, and since 1998 by World Kitchen. In fact, since the 1980’s, most, if not all consumer glass bakeware manufactured in the U.S. for consumers has been made of soda lime glass. Consumers should know that soda lime glass, such as that used to make PYREX glass bakeware, is significantly more resistant to breaking on impact than borosilicate glass and comparably resistant to breakage caused by severe temperature changes.”

World Kitchen itself states that it has received complaints from only “a very small number of consumers” about unexpected breakage. It notes that the Consumer Safety Product Commission has found no safety issue with Pyrex glass bakeware.

Pyrex Bowls are available from Amazon.

Le Creuset French Ovens

Le Creuset has been producing handcrafted French Ovens in their foundry in Northern France since 1925. Their cookware is made with enameled cast iron and is known for lasting decades. The Le Creuset foundry uses standard sand-casting methods to produce its cookware. After hand finishing, items are sprayed with two coats of enamel, and each is fired at 800 °C. The enamel becomes resistant to damage during regular use.

Le Creuset cookware has a lifetime warranty that the products are free from defects in material and workmanship.

If you want an equivalent American-made product, see Lodge Dutch Ovens. We choose to feature the Le Creuset French ovens because, based on our research, they have an edge in quality.

Le Creuset French Ovens are available from Amazon for about $235.

If you want to remove both chloramines and chlorine from your shower, I recommend a vitamin-C based shower filter, like the Sonaki In-Line Filter

This combination filter is also available — it incorporates a sediment filter and a Vitamin C filter into one unit.

The Details

Almost all popular shower filters available today only remove 20% – 80% of free chlorine (not total combined chlorine) from your shower. This includes shower filters that are certified by the NSF #177 Standard — unfortunately this standard only indicates that a filter will remove 50% of free chlorine in the water.

Also, many cities now treat water with chloramines instead of chlorine. There are no conventional shower filters that will remove more than a small amount of chloramines from your shower. The only way to remove chloramines is to use a Vitamin-C based shower filter which are only made in Korea and Japan.

Why Filter Your Shower?

Because your skin absorbs substances while showering. Typically, 60% of the chlorine that most people absorb daily comes from showering in chlorinated water. Chlorine damages your hair and skin.

Shower water also contains things like heavy metals and VOCs (volatile organic compounds). Ideally, all these things should all be filtered out, but filtering water at the showerhead is problematic, because the water is typically hot and under high pressure, making filtration difficult. Carbon filters, which are normally excellent at remove chlorine, cannot handle the volume and heat of shower water.

Because of these problems, most shower filter makers rely on a metallic medium called KDF. Shower filter vendors typically show impressive charts to demonstrate long-term removal of chlorine. However, if you read the tests carefully, you’ll see that they apply to “free chorine” (chlorine that has not combined with other constituents in water), and the reality is that KDF-filters have little effect on “total chlorine” (combined chlorine). In fact, chlorine is often added at the water plant as a blend with ammonia called “chloramine.” KDF is not effective at removing chloramine or combined chlorine.

Here are the details on my recommended shower filters:

Vitamin C Shower Filters

Vitamin C shower filters are very effective in removing chlorine and chloramines from shower water. Chloramine or NH₂Cl  (a combination of chlorine and ammonia) is now commonly being used in place of chlorine for disinfection, but chloramines are not easily removed from water. Carbon filters are virtually useless in showers, because they do not work when the water is warm, and they also get clogged fairly quickly. KDF filters also don’t perform well in hot water, and they don’t remove chloramines. However, Vitamin C filters can remove chloramines effectively from water. To back this up, the San Francisco Public Utilities Commission now states on their website that only Vitamin C can be used to remove chlormaines from municipal water. Here is the quote from the Commission:

Vitamin C (ascorbic acid) has recently been included in AWWA Standard (AWWA, 2005b) as one of the methods for dechlorination of disinfected water mains. SFPUC and other utilities have used Vitamin C for dechlorination prior to environmental discharges of chlorinated and chloraminated water. Since ascorbic acid is weakly acidic, the pH of water may decrease slightly (Tikkanen et al., 2001). Ascorbic acid has been used for a long time as one of the dechlorinating agents for preservation of chlorinated or chloraminated water samples for laboratory analysis.

The full document can be found here.

Vitamin C filters are simple in design — they contain a solid block of Vitamin C (ascorbic acid), and water runs through the filter and comes into contact with the Vitamin C. The Vitamin C neutralizes about 99% of the chlorine and chloramines in the water, and their effectiveness does not diminish until the Vitamin C is completely used up.

My recommendation for a Vitamin C showerhead is the Sonaki In-Line Filter

The filters last about 2-4 months before they need replacing, depending on how many showers you take. The filter is transparent, so you can see when the Vitamin C has run out.

Refills for the Sonaki filters are priced at $37 for 5 filters.

Sprite HOB-CM Brass Shower Filter

If you are just interested in removing free chlorine and sediment from your water, my recommendation is to use a Sprite Shower Filter. This filter is NSF Certified to standard #177 for shower filtration. It removes most free chlorine and some combined chlorine, sediment, hydrogen sulfide, iron oxide. Besides the fact that it does not remove chloramines, this is pretty good filter, and it is constructed with brass instead of the usual plastic.

The filter comes with a one year warranty, it is rated to filter 20,000 gallons or last 12 months, which ever comes first. It should be flipped half-way through the year. If the O-ring on the filter breaks, Sprite will replace it for free.

You can get the Sprite Shower Filter on Amazon for around $48.

See also my review of low-flow shower heads — these shower heads can be used in conjunction with these filters.

• The best pair of binoculars is the Carl Zeiss Victory HT Binoculars. They are the brightest binoculars available, and sport a robust and ergonomic design. There is no better option for bird watchers and hunters.
• Nikon Monarch 5 offers a much more affordable yet comparable quality pair of binoculars.
• The best pair of compact binoculars for hikers and everyday use are Bushnell Legend Ultra HD.

The Details

Stellar improvement in binocular technology has leveled the optical playing field. Specialty brands such as Swarvorski and Zeiss still have an edge over their lower priced competitors, but the gap has narrowed enough that you can comfortably purchase a mid-range option without losing much in the way of clarity, color, durability, and ergonomic design.

There are a few important considerations to weigh when picking out a pair of binoculars, and what option is best for you depends on whether you will be gazing at stars or birds.

The optical specification of a pair of binoculars is represented by a number that looks like a basic multiplication equation. 8×42 and 10×42 are the standard binocular specifications, and are the numbers that are best for general purpose use.The first number, which is invariably the smaller of the two, refers to the magnification power of the binoculars. It represents how many times larger the object will appear through the lens than it would to the naked eye.

The second number is the objective lens diameter, which is the larger piece of glass at the front of the binoculars. Objective lens diameter determines how much light is let in. The larger the lens diameter, the more light is let in. Photographers can think of it like aperture on a camera lens. A larger lens also means the binoculars will be heavier, which might compromise how long you are able to hold them steady. Increasing upper arm strength is a great solution to this problem, and will allow you to hold a pair of binoculars for longer while enjoying more light.

Field of View

The field of view is determined by the size of the eye piece and represented in degrees. Therefore, a 7.0 degree field of view would be 7 out of a 360 degree circle.  Wide angle are 7 or more degrees, while standard binoculars are around 5 degrees.

As magnification goes up, the field of view goes down. Birders will sacrifice some field of view for increased magnification. If you want to take in scenic panoramas, opt for a wide angle lens.

Other Factors To Consider

Get a pair of binoculars with a long eye relief if you wear glasses. Eye relief is the vertical distance to which your eye is supposed to sit, and is measured in millimeters. 13-15mm is considered a long eye relief, and the minimum a bespectacled individual would want to comfortably use the binoculars.

Reactual readers will also want to take note of the lens coating. The objective lens will be protected by an anti-reflective coating to minimize glare when light hits the surface. Fully multi-coated lenses are the best for performance and durability, as they enhance clarity, maintain integrity of color, and protect the lens from scratch and other damage.

We also highly recommend you choose a pair of binoculars that is waterproof or, at the very least, water-resistant. Even if you don’t plan to use your binoculars by water, fog and moisture in the air could potentially damage your pair.

Zeiss Victory HT: The Best Binoculars For Hunters and Birders

If you have the money to spare, there is no better pair of binoculars available than Zeiss Victory HT. The manufacturer is a specialty optics company with more than 200 years of binocular manufacturing expertise, and the Victory HT are engineered with precision to deliver the brightest color and most ergonomic design of any pair of binoculars. Released in 2012, Victory HT are made in Germany with the best products and most advanced technology.

They are the brightest premium binoculars in the world. They are the highest contrast and deliver more than 95% light transmission, 5% higher than other premium binoculars on the market. This jump is thanks to the new Schott High Transmission glass, which is exclusive to Zeiss. Schott has been developing special optical glass for more than 125 years, and their HT glass has the highest transmittance levels of any optical lens. This cuts down on a phenomenon known as “thermal lensing effect” and increases blue spectral range, which is particularly helpful in low-light situations.

Hunters and birdwatchers benefit most from the extra color in low light situations, as the HT glass makes the most of deep twilight. The lenses are protected by anti-fogging material which keeps them clear in the early morning cold. The extra color is still noticeable in general daytime use, but the difference is not as drastic as in dim or low-light viewing. If you plan to use your binoculars in daytime, the extra price tag is probably not worth the incremental improvement in color crispness.

The ingenious design of the Zeiss Victory HT sets it apart from competitors. It has a compact bridge and a large easy-to-use focus wheel. The comfort grip system allows you to grasp both optical tubes without a hinge in front of binoculars, and a long eye relief provides a comfortable viewing experience for those with and without glasses. It also has a double hinge feature which increases durability by minimizing the chance of breaking and a robust chassis that is made from lightweight magnesium.

The biggest drawback of the Zeiss Victory HT is obviously the price. Some commenters noted that other premium priced binoculars come with better kit (case, cleaning cloth). The lifetime warranty and 5 year no fault policy do provide some peace of mind for dropping so much on a pair of binoculars.

Zeiss also offers the Victory HT in 10×42, which gives you stronger magnification at the expense of a few degrees in field of view. Another option is the 10×54 version of the Victory HT, which Zeiss launched in 2014. Much lighter than other models with such a large objective lens diameter, this option is great for stargazers and deer hunters who need to make the most of nearly non-existent light.

Another Option For Bird Watching: Nikon Monarch 5

If you are willing to sacrifice color quality, Nikon’s Monarch 5 Series offers near identical image quality for a fraction of the price. It is a mid-level binocular with multi-coated Nikon ED (extra-low dispersion) lens that delivers sharp, high-contrast views. The ED Glass lenses and Dielectric High-Reflective Multilayer Prism Coating were previously reserved for Nikon’s more expensive models, but are available in the Monarch 5 series.

They have a 6.4 degree field of view, and maintain image sharpness outside of a 5 degree diameter up to 80%.

The exceptional design of Monarch 5 is durable and intuitive. It is very light, though not as light as Zeiss (21 oz versus 16 oz). The focus knobs are precise and smooth, very easy to adjust and find the best clarity. We appreciate the fully waterproofed rubber armored fog proof housing, which make this a durable and comfortable pair of binoculars to hold.

One complaint Monarch 5 owners have is that the lens cap is loose fitting, which leads to many lost caps. Nikon assures that this was an intentional design choice, but it nonetheless leads to problems.

 Best Compact Binoculars For Everyday Use: Bushnell Legend Ultra HD

Compact binoculars are lightweight and portable, perfect for hiking and general use while travelling. Any pair with an objective lens diameter smaller than 30mm is considered to be compact.

Bushnell Legend Ultra HD offers stunning HD image, thanks to ED Prime Glass. They are coated with anti-reflective lens and are secured in a lightweight magnesium chassis that is waterproof and fogproof.

It’s important to keep indoor humidity at an optimum level (45 to 65 percent). Dry air in the winter is one the main causes of sinus infections and sore throats. Dry air is also hard on the lungs and tends to cause dry skin.

The Venta Airwasher is a unique device that cleans and humidifies the air in your room by drawing air over a slowly rotating drum which is covered with water. This low-tech “cold evaporation” system is very efficient  — the Venta draws only seven watts on the highest setting.

I’ve been testing a Venta in my house for a couple of months now. It’s winter here, and the unit  has been running 24 hours a day on the second highest setting. On average it consumes about 1.5 gallon of water per day.

The Venta requires fewer refills than most humidifiers and fewer cleanings too. Most humidifiers require cleaning every third day, but the Venta requires a cleaning only every two weeks. In order to cut down on the cleanings, it relies on a proprietary chemical mixture. It comes with a two week supplies on the cleaning mixtures. For $20, you can purchase a 35 ounce replacement bottle that last four months.

The Venta Airwasher has a ten year warranty and each model is fully recyclable. It is manufactured in a facility powered entirely by wind energy in Germany.

The Venta Airwasher is available from Amazon for about $300.

The Details

Tower air filters, frequently using HEPA technology, are designed to reduce exposure to indoor irritants and allergens such as dust, cigarette smoke, pollen, pet dander, mold and mildew spores and other particulate matter. Effective air filtration is especially important for those with allergies or respiratory problems such as asthma. Studies show that those who suffer allergies are often sensitive to multiple allergens, making it nearly impossible to remove environmental triggers without the use of technology such as air filters using the HEPA technology.

HEPA (high-efficiency particulate air) filters work by forcing air through a fine mesh designed to trap particulate that can escape standard filters found on HVAC systems. Many tower air filters contain a HEPA filter, and as air is pulled into the tower by a fan, it is pulled through the filter where particulate is trapped and then clean air is forced back out. HEPA filters are remarkably effective at eliminating environmental irritants, capturing 99.9% of airborne impurities 0.3 microns in diameter, or larger.

Consider the air change rate (ACH), which defines how many times the portable air filter will clean an entire room’s air during one hour. An ACH of 5, for example, indicates the air will be cleaned every 12 minutes.

Another factor to consider is the CADR ratings, which is the clean air delivery rate. This identifies how powerful a tower air filter is. CADR indicates how many cubic feet of air the unit can filter in one minute. You may see ratings for CADR related to irritants such as dust, pollen and smoke on the tower air filter’s packaging. Look for higher numbers if you have a large space, or consider purchasing more than one tower air filter. Here are the best standalone air filters.

The Best Overall Stand-Alone Air Filter: RxAIR Plus

For most people, a stand-alone air filter is a convenient way to cut down on air pollution and minimize annoying affects of allergies. For others, an air filter is a literal lifesaver, killing airborne bacteria and viruses. If you have a weak immune system, go with RxAIR Plus, an air purifier trusted by hospitals around the world.

This high end air purifier harnesses the germicidal ultraviolet light (UV-C) to clean the air as well as germs and viruses ranging from H1N1, TB, and the flu. In addition to a 99% elimination of airborne bacteria and viruses in a space of up to 800 sq. ft, the RxAir uses a system of traps and baffles to catch large particles such as pet dander and dust.

The unit comes with a 5 year warranty that places cartridge replacement. Replacement cartridges are available to keep the machine running at max efficiency even after 5 years. The RxAir Plus comes with a whisper-quiet fan that allows it to purify the air without causing a lot of disturbance, and you don’t have to worry about changing out the filters.

The Best Stand-Alone Air Filter For Value: GermGuardian True HEPA AC4825

This best-selling unit is an all-around good value, offering true HEPA filtration, a charcoal filter to reduce common odors, and UV-C light technology to kill bacteria and germs. The unit is Energy Star qualified, meaning it meets the strict energy efficiency guidelines set by the US EPA.

Air cycles through three stages to ensure maximum effectiveness. First, air is filtered through a pre-filter and charcoal filter to capture large particles and remove odors. Then, air is filtered through the HEPA filter, capturing 99.97% of airborne particles larger than 0.3 microns. In the last stage, UV-C light kills airborne viruses and bacteria, and titanium dioxide destroys the molecules that cause odors. Common viruses and bacteria that can be killed by the UV-C light stage includes rhinovirus, E. coli and streptococcus, responsible for millions of illnesses each year.

One downside is that it does require an air filter change every 7 months. The GermGuardian tower air filter includes an indicator light that blinks when it’s time to replace the filter or bulb.

The Best Compact Stand-Alone Air Filter: Honeywell QuietClean Compact Tower Air Purifier

The compact Honeywell QuietClean weighs just 1 pound, is 12.6 x 17.8 x 10.5 inches, and has a built-in handle, making it easily transportable and ideally suited for any tight space, including a nightstand, table or you can place it on the floor. It is whisper quiet, has two speed settings that can be set via an easy control knob on the top of the unit, and a permanent, washable iFD filter.

IFD (intense field dielectric) filters are a honeycomb of hollow air channels with floors and ceilings alternately charged or grounded via embedded electrodes to create a powerful, polarized electrical field inside the air channels which can trap 99.99% of particulate matter 0.3 microns or larger, including virtually all viruses, bacteria and spores. The iFD filter can be removed from the unit, easily washed with water and reused, so it never needs replacing.

The Honeywell QuietClean has a CADR rating of 40, meaning it can filter 40 cubit feet of air per minute, ideal for smaller rooms up to 62 square feet. The energy efficient design requires only as much electricity as a small light bulb to run, reducing your energy costs as compared to many other models. Air is effectively filtered through the unit 5 times per hour.

The Best Standalone Air Filter For Allergies: Honeywell True HEPA Allergen Remover

The Honeywell True HEPA Allergen Remover tower air filter is the number one recommended model by allergists, and the Honeywell brand is recommended by 7 out of 10 physicians who recommend the purchase of an air filter. This portable unit weighs just 21 pounds, making it simple to carry from room to room via built in handles on the sides. It can circulate the air in a 21’ x 22’ room up to 5 times per hour, and has a powerful CADR rating of 300, meaning it can clean up to 300 cubic feet of air per minute. There is an activated carbon pre-filter to help reduce common household odors, such as those caused by pets or cooking.

The unit features easy tap electronic controls, 3 cleaning levels and a turbo clean setting. A timer can be set to shut off automatically after 2, 4 or 8 hours, and there are built in electronic filter replacement reminders. A light/LED dimmer control on the top of the unit makes it easy to determine the operating status even in the dark. This unit functions most efficiently in a medium to large sized room and includes a true HEPA filter, guaranteeing 99.97% of allergens and other irritating particulate will be removed from the indoor environment.

The Details

Date night for two at the movies can easily run over $60 dollars in an urban area once you factor in exorbitant ticket prices, concessions, and parking. All that and you risk sticky seats, texting teenagers, and chatty couples. Making your own home theater is becoming an increasingly affordable alternative to pricey and unreliable nights out at the movies, with quality projector prices falling and pixel counts increasing.

Once upon a time you needed a spacious, cave-like room to make owning a home projector a feasible entertainment option. But the proliferation of short-throw projectors and steadily rising lumen counts mean that projectors are no longer exclusive to suburban basements. Even apartment living rooms can benefit from the immersive experience of an HD projector. You just need to make sure to buy the right projector for you.

There are a couple factors to keep in mind when picking a projector. First, determine the brightness of your room and how large your screen will be. If you do have a windowless room without any source of natural light, you don’t need a high lumen (measure of brightness) count. Likewise, if your projector screen is less than 100 inches, there is no need to pay up for a 4k resolution projector.

Since your projector will likely stay put in your house, things like portability and built-in audio playback aren’t a concern. Instead, consider whether the projector has low lag time, if it has 3D capability, whether it supports media streaming services, what its casting distance is, and image quality.

I’ve identified a few of the best projectors for different consumers below:

The Best 3D Projector

If you are still deciding between an LCD TV and projector for your home theater, a few minutes with a high quality 3D projector will put an end to your waffling once and for all. The latest 3D projectors give a true approximation of the cinema multi-plex experience. Their grand size and gorgeous colors convey the 3D experience in a way that an LCD TV just can’t. Immerse yourself in three dimensions with crosstalk,” the blurry illusion created by two different transmission channels.  Like all 3D technology on the market, there is some loss in brightness when viewing in 3D.

A few alignment options give some flexibility in set up. Lens shifting allows for the projector to be slightly off center from the screen, though you will have to manually do any lens shifting.

The 1700 lumen lamp will last 5000 hours in eco or 2000 at the highest setting. In low and medium ambient lighting, this projector gives bright and crisp colors and HD black. The lumen count is a bit low for bright rooms, so this is best in dens and media rooms.

The HW40ES is sold as a “gaming projector,” and users have the option to use it in a gaming mode that is said to reduce lag. Reviewers have empirically proven that lag time is reduced to 24 milliseconds, which is one of the absolute best for gaming.

It does not come with 3D glasses, so you will need to invest in a pair that is compatible with Sony projectors.

The Best 4k Projector

For those that want only the best image quality, sharpest contrast, and latest tech, a 4k projector is the way to go. 4k is the new gold standard for video resolution. The new video technology refers to the 4,000 thousand pixels found alongside the horizontal line display. Right now, Sony enjoys a total monopoly of the 4k home projector market. Of the 4k projectors Sony offers, the VPLVW350ES SXRD is the best value for an unbeatable image.

This behemoth of a projector weighs close to 40 pounds and is a commanding 25.1 x 22.9 x 12.6 inches. Inside comes Sony’s SXRD 4k movie theater technology and anamophic 3D capability. This top of the line tech enables you to cast onto a larger screen than some 1080p projectors. Sony says that full brightness (1500 lumens) and resolution are achieved on a 150 inch screen.

Since 4k is relatively new, not a whole lot of media is specifically made for 4k resolution. This is definitely changing, but 1080p HD is still the standard as of now. Sony equipped with the 350ES with Super Resolution upscaling so you can enjoy your content in 4k in the meantime. It uses a ‘Mastered in 4k’ algorithm to upscale HD movies and shows into 4k content. Sometimes this results in a noticeable difference, other times its hard to make a meaningful distinction.

The VPLVW350ES SXRD comes with a 3 year warranty.

The Best Projector for Football Fans

Plan to marathon NFL games all Sunday? You will need an extra bright projector if you are going to set up your home theater in a room with any natural light sources to get the most our of your daytime viewing. The brightest home theater projector is the Epson Home Cinema 1440, which has a staggering 4400 lumens.

This model uses 3LCD projectors for Full HD 1080p images that are rated three times brighter than other projectors in its class. This means you get stunning HD imagery in well-lit rooms, even with all the blinds up.

Easy slide horizontal keystone correction and automatic vertical keystone correction make alignment relatively easy. However, a lack of lens shift means you have to mount the projector dead center from where the image will be projected. This model is also lightweight and compact for a home theater projector, weighing just 13 pounds.
