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.

The Details

The Best Waterproof Bluetooth Speaker: Ultimate Ears UE Boom 2

Pros: Waterproof, rugged, great battery life, impressive sound, lightweight

Cons: playback controls occasionally unresponsive

A favorite pick of top tech magazines, the UE Boom 2 is a remake of the popular, original UE Boom.  Although just over 1 lb., the compact, cylindrical speaker projects a loud, clear sound with deep bass in all directions.  Unlike many delicate tech gadgets, these speakers were meant to be taken outside – the outer shell is resilient, rugged and made to withstand dings and dents.  It’s not just water-resistant – it’s waterproof – and can be submerged in over three feet of water for up to 30 minutes.  The rechargeable battery lasts an impressive 15 hours, perfect for a weekend camping trip with a group of friends.  The UE Boom 2 also offers a variety of other features, including the ability to sync with a second UE speaker for even more sound, intuitive app features, and a variety of color options to suit any style.

The UE Boom 2 is available at Amazon for around $200.

The Best Bluetooth Speaker for Sound Quality: FUGOO

Pros: Powerful sound, excellent battery life, durable design, customizable “jackets”

Cons:  Does not give visual cues on volume or battery life, changing jackets requires some dis-assembly

According to TechRadar, the FUGOO Bluetooth speaker is one of the industry’s best-kept secrets.  Although some high-end Bluetooth speakers from well-known brands, such as Bowers & Wilkins, Bang & Olufsen, Sony, Marshall Kilburn, and Bose, may boast of higher quality sound, many of these are not realistically portable, or likely to be used as portable speakers, due to their size, weight, and price tag.  However, the FUGOO is a true portable speaker at a little under 1.5 pounds, and includes a durable core and different exterior “jackets” depending on the purpose and environment.  Specifically, the core is itself a rugged machine capable of handling dings, dents, and spills.  The “style” jacket offers additional protection and a streamlined silhouette.  The “sport” and “tough” jackets offer additional protection.  The speaker sound is exceptional; music lovers will be astounded by the depth and clarity of the sound produced via its six drivers, including two tweeters, two mid/sub drivers, and two passive radiators.  The FUGOO also offers an unbelievable 40 hours of continuous battery life.

The FUGOO does have some small drawbacks.  Its streamlined, minimal visual design only indicates whether the machine is turned on or off.  All other cues are voice-activated, which means a simple glance to check the volume level or battery life is not possible.  Additionally, the jackets are not easily interchangeable.  Although the “style” jacket slides and locks in, the other jackets require a little more assembly; many reviews noted changing jackets was frustrating and somewhat confusing.

The FUGOO Bluetooth speaker is available on Amazon for $178 to $230, depending on jacket type.

• Tusa Freedom HD
• Atomic Frameless 2

A scuba trip can take you to the  tranquil waters of a Caribbean cove or to the murky depths of the Scottish aisles. But no matter the environment, you will need a quality scuba mask to take in your surroundings. Cheap masks fog up or obstruct your view with a narrow field of vision and low-quality tinted glass. When choosing a scuba mask, only comfort matters more than visibility.

There are two main styles of scuba mask: multi-lens and single-lens. Multi-lens masks have two separate lenses divided by a nose bridge. They are easier to clear and can be outfitted with corrective lenses, but have a narrower field of view. Therefore, single lenses tend to offer better visibility.

Best Overall Scuba Mask for Visibility: Tusa M1001 FREEDOM HD

The M1001 Freedom HD is a framed single lens mask with an incredible field of view: 6 inches across and 3 inches from top to bottom. The immense lens provides panoramic near uninterrupted viewing, with some divers stating that they can’t even see the top of the mask. Its wide field of view earned the top score in Scuba Diving magazine’s 2016 best mask round up.

Because of its large circumference, the Tusa Freedom HD is ideal for people with large heads and big noses. Usually, the big-nosed will have to settle for a two-lens option to comfortably fit their face. The mask also has 180 degree adjustable buckles that bend outward and inward to fit your face and help for storage.

The mask is quality made and the supple silicon clings effortlessly to your face. The skirt has dimples that soften the silicon and molds to the face, decreasing the chance of a leak. It also has stability ridges that hold the mask skirt in shape as you descend.

After the normal treatment (a rubdown on the lens with abrasive toothpaste) there are no problems with fog.

Best Frameless Scuba Mask For Visibility: Atomic Frameless 2

Frameless single lens scuba masks offer unobstructed panoramic view for unmatched visibility. The Atomic Frameless 2 is among the best frameless masks currently on the market, popular among divers for its thoughtful design and luscious comfort.

The mask earns top marks in visibility for two reasons. First, the lens is constructed with a glass designed to maximize optical quality without color distortion. Most scuba masks have a green tint as a result of iron impurities. This green tint distorts light transmission and blocks true colors, a bummer when you are trying to take in the majestic panorama of exotic fish and flora. Atomic uses “ULTRACLEAR Lenses,” which offer clear and distortion free view.  This allows 99% light transfer, which makes a world of difference underwater when compared to cheap green view.

The second reason that this scuba mask is great for visibility is its wide design. Like the Freedom HD, this mask is extra-wide for a panoramic view. While not as wide on top, it still surpasses most low volume masks with a wide field of vision.

In addition to visibility, this is a real comfortable mask to wear. It uses high quality super soft silicone which seals effortlessly to your face. In fact, the whole mask is made of high quality materials for high durability and resistance to accident.  Atomic also offers the mask in three sizes, so you should be able to find one that fits your face.

The DeVialet Silver Phantom is the ultimate compact wireless hi-fi system, delivering incredible power with no sacrifice of sonic clarity even at the highest volumes.

The Details

The best to be found in a compact wireless hi-fit system in 2016 is the DeVialet Silver Phantom. DeVialet claims that the Phantom (with the Silver Phantom being the upgraded, even more powerful version) was designed over a period of 10 years, taking 40 engineers, 88 patents, and $30 million to bring to fruition.

The Silver Phantom is spherical (actually, oblong) in shape and white with silver dome drivers. The 26-pound music machine is lovely to the eye. The only control on the unit is a white “Reset” button that’s hard to find (to preserve aesthetic appeal). Everything else is controlled remotely via your Android or iOS device. The Phantom’s heat sink, blended seamlessly into its backside, reminds me of fins on some elegant fish.

The Silver Phantom supports many file formats including AMP3, aptX (which isn’t available on iPhone), AAC, AMP3, Apple Lossless, FLAC, and OGG Vorbis. The music machine streams them with all lossless quality kept perfectly intact. For those who prefer wired connections, a flap at the back of the unit lifts to show Ethernet and TOSLINK ports.

DeVialet engineers explain that the Silver Phantom’s structure accommodates the two proprietary “Heart Beat Implosion” aluminum bass drivers (woofers) placed across from each other underneath a pair of thin aluminum domes. The diaphragms of these woofers (which have a 26mm peak-to-peak stroke), just like those of the coaxial midrange and tweeter drivers ensconced at a 90-degree angle to them, are flush with a spherical superstructure. In terms of acoustical physics, their being so situated focuses sound waves toward the Phantom’s center (which is vacuum sealed so as not to fissure or crack due to sonic onslaught).

This concept (which DeVialet calls its  proprietary ACE or “Active Cospherical Engine” loudspeaker technology) is inspired by the work of famed Princeton, NJ acoustical engineer Dr. Harry Ferdinand Olsen of RCA Labs. In experiments he conducted in the 1930s, Olsen concluded beyond the shadow of a doubt that a spherical speaker cabinet is the most efficient, the best at maintaining the fullness of the signal’s original sound quality. The closer that acoustical engineers can come to creating a single point in space out of which music emanates, the closer to “pure lossless” the music is.

The sheer sonic power of the Silver Phantom is quite simply astounding. At maximum volume, it produces 3000 watts of power to generate a jaw-dropping 105dB. Furthermore, as you increase the volume the Phantom’s sound becomes even cleaner. (Any extraneous sounds like humming or clacking that you hear are coming from the surface that the unit’s sitting on or is close by to, or may be the result of a low-quality recording.) Strong bass and outstanding clarity are always there at any volume level, but once you turn it up enough to really let those woofers run wild the audio experience deepens, whether you’re listening to R&B or a symphony orchestra, or even solo classical guitar.

But even at extreme volume, the Phantom never distorts or gets out of phase. The sound is always complex but balanced, one might even say “silky”, with excellent separation between highs and lows.

The Phantom’s components and outer shell are protected from their own heat and energy (and from outside impacts such as drops) with braided sheets of Kevlar acoustic insulation, which at once cool the the circuit boards and keep the unit so strong as to be literally bulletproof. Durability is no issue.

If there’s a flaw with the Silver Phantom, it’s that DOESN’T yield stereo surround sound. You would need multiple Phantoms to achieve that (or a close approximation). DeVialet engineers have made it possible to chain together up to 24 of them. (Oh, and one more flaw: the visually obtrusive, bright-greenish-yellow power cord! Who thought that up, anyway?)

The BeoSound 35, made by Bang & Olufsen, is a wireless hi-fi “super soundbar” that stands as an unbeatable “all-in-one integrated music system”.

The Details

Renowned Danish audio products engineers and designers Bang & Olufsen (B&O) have come up with a soundbar that’s not a mere soundbar in the usual sense but something far beyond that, aesthetically and sonically. It’s the pentagonal BeoSound 35, a wireless “all-in-one integrated music system” that I find formidably good among mounted or standing audio systems of this kind.

The BeoSound 35 can deliver clear and powerful sound for 24-bit/192 kHz high resolution audio. Other supported formats include MP3, AAC, AIFF, ALAC playback, FLAC, WA, and WMA (but not WMA lossless). What’s more, support for streaming services including Spotify Connect and the Deezer app is integrated right into the system. Likewise, so is support for AirPlay, BLNA, Google Cast, and TuneIn. There’s connectivity for Bluetooth 4.0 alongside “old school” hard-wired inputs. The company has, characteristically, made sure that it’s simplicity itself to pair up the BeoSound 35 with other B&O audio equipment if you want multi-room audio. According to B&O, all of this makes it a true “all-in-one integrated music system”, and I have to concur.

The unit has an OLED display built in, along with on-board touch controls. You control the volume with a finger swipe.

Behind the face cover, you find a pair of forward-facing 4″ woofers and a pair of 0.75″ tweeters which are angled at 90 degrees to the woofers, each pair driven by an 80-watt Class-D amplifier. The unit’s frequency range is from 45 Hz to 22 kHz.

The BeoSound 35’s aluminum outer shell and elongated pentagonal shape are a seamless blend of optimal function and form. The aluminum simultaneously helps with durability and heat dispersion. The pentagonal shape is much more aesthetically pleasing than the usual “rectangular box” shape of mounted wireless hi-fi speakers, but it also provides additional sound quality. That is, with the unit’s bigger loudspeaker at its center and the smaller tweeters on the ends you experience a well-balanced, 180-degree, room-filling sound without the annoyance or disappointment of hot spots or dead zones.

It has been thoroughly demonstrated that the BeoSound 35 can utterly cascade a room with crisp, high quality audio which doesn’t allow Beats-like bass dominance or distortion — whether you mount the system on the wall or set it up on a table with the included aluminum stand.

At the time of this writing, the BeoSound 35 has only had demo models heard. B&O are putting it on the market in April, 2016.

The Details

The lightweight (about seven ounces) Bose SoundLink Around-Ear Wireless Headphone II model is a remarkable set of less-than-$300 headphones. Unlike their predecessor these wireless, Bluetooth-enabled headphones don’t come with an attached ugly dongle, making them efficient to use and able to give you the feel, sometimes, that you don’t even have any headphones on at all while the music or the talk streams through your ears.

The Bose SoundLink Around-Ear Wireless Headphone II set features memory-foam earpads designed to help the headphones “learn” the shape of your ears, and they are quite comfortable, also including “glass-filled nylon and corrosion-resistant stainless steel” for durability. Controls are integrated on the right-ear cup while being intuitively easy to use.

These are not “noise cancelling” headphones, but the memory-foam earcup linings do a fine job of keeping out unwanted external noises.

A strong feature of these wireless headphones is that you can attach them to more than one device at a time by way of the incorporation of Bluetooth 4.0 and supporting multi-link technology, which makes it seamless to switch between listening to music and taking a phone call with the touch of the center control-button (which also acts as the fast forward and rewind toggle button when you’re in music-listening mode).

Needless to say, the sound quality is overall the most important feature of headphones, and the Bose SoundLink II wireless set delivers on that superbly. As is virtually always the case with Bose headphones, the sound is sleek and well-balanced with barely any distortion even at high volumes, making use of Active EQ and volume-optimized EQ technologies.

The treble is clean and clear while the bass has strong punch. If there’s any drawback to the sound quality, it’s that these headphones won’t impress music fans who love their music to be bass-heavy. The bass is punchy but the overall sound is balanced, not favoring the bass end of the music.

There’s also the added benefit of an excellent battery charge of 15 hours. You can also do a “quick charge” in just 15 minutes which lasts for two hours.

What it all comes down to is that you would be hard-pressed to find better wireless headphones priced at less than $300 than the Bose SoundLink Around-Ear Wireless Headphone II.
