Most Effective Filter Overall: Healthmate HM-400
We 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 that is certified to remove 99.97% of all particles in the air over 0.3 microns. The filter lasts 5 years before it needs replacement. These filters are made in Buffalo, New York and they come with a 5-year mechanical warranty.The HM-400 costs about $530, and the less powerful Healthmate Jr is available for about $375.
Best Filter For Removing Embedded Odors
If you need to remove really 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 under $100, but an ozone generator should not be used as a general air filter. They should only be used when needed, and when a room is vacant.
Best Filter For Removing Pollen and Dust Filtration
While the Healthmate is great for chemical filtration, there are other filters that work faster at particulate filtration. If your primary goal is to remove dust and pollen from the air, I would suggest getting a Coway Mighty. This filter is one of the best for removing particulates from the air quickly.
The Details: Healthmate HM-400
Most air filters are built to remove particles from the air, but the Healthmate HM-400 is specifically designed to remove odors, chemicals and gases from the air. It does this effectively because it incorporates 15 pounds of activated carbon and zeolite into the filter media. The sheers 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).
I’ve been testing 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 that suspended in the air. In my few informal tests, I found that the Healthmate was able to remove all traces of smoke odors from a room in about 45 minutes. I will be conducting further tests in coming months.
These are the four different filter types inside:
- A pre-filter that removes particles visible to the eye (dust, hair and pet dander)
- A particle filter that removes medium sized particles (molds, spores and pollen)
- A 15 pound filter of activated carbon and zeolite for removing odors, chemicals and gases
- A large surface area filter (60 square feet) that removes 99.97% of particles larger than 0.3 microns
