There are few things as elementally important as clean air. Each of us takes up to 30,000 breaths a day. What our bodies want is oxygen, but what we actually inhale often contains all sorts of less-than-good stuff. This is especially true of our indoor air, where a wide variety of contaminants can accumulate.

The Best Air Filters for Wildfires

Experts recommend electronic air filters to mitigate the impact of wildfires on indoor air quality. These filters are designed to remove fine particulate matter, smoke, and other airborne pollutants from the air.

Electronic air filters have a higher efficiency in removing fine particulate matter, and we recommend the Austin Healthmate Plus. This model includes a layer of 60 square feet of certified HEPA to remove 99.97% of all particles larger than 0.3 microns, including particulates from wildfires. The Healthmate Plus also filters viruses, bacteria, VOCS, and odors, as well as particles easily seen by the naked eye (e.g.dust, hair, and pet dander) and smaller particles (e.g. molds, spores, and pollen).

The Best Air Filters the Coronavirus & Other Viruses

In addition to their other benefits, HEPA filters can remove bacteria and viruses from the air. Whenever someone in our home is sick, I run our filters with hopes of keeping the rest of us well. Experts agreed that this was a key strategy in fighting the spread of COVID-19.

Austin air filters contain true medical grade HEPA that removes 99.97% of all particles larger than 0.3 microns and 95% of all particles larger than 0.1 microns. Scientists say that the size of the coronavirus is .125 microns, so yes, these filters will capture the virus. Moreover, experts say that the droplets the virus travels in measure at least 1 micron, which is easily captured by a HEPA filter.

In addition, there is apparently a link between living in areas with poor air quality and experiencing severe COVID-19 symptoms.

How to Clean Indoor Air

The good news is that there are ways to clean the air of a range of contaminants.

Here are four ways to clean up the indoor air:

  1. Throw open your windows when the weather permits; even in cities, outdoor air is usually better than indoor. (Obviously, this is not true during wildfire seasons.)
  2. Purchase some charcoal air purifiers, which clear everything from odors to VOCs.
  3. Stock up on houseplants, which both absorb airborne toxins and generate clean oxygen, making them a great passive air filter.
  4. Invest in 100% wool rugs for your floors, as wool naturally absorbs VOCs.

Austin Air Vs. AirDoctor

AirDoctor filters are also great. We lean towards Austin mostly because of the cost, as you can see here.

HEPA Air Filters

We’ve all heard this term (which stands for High Efficiency Particulate Arrestance), but probably don’t know exactly what it means.

To be certified as HEPA, a filter must trap at least 99.97% of all particles larger than 0.3 microns. Many of the particles caught in a HEPA filter (including many chemicals) are so tiny they can’t be seen with the naked eye.

HEPA filters also trap mold, viruses (including the coronavirus), and bacteria, so they create a more sanitary environment. HEPA filters also trap larger particles that can cause lung irritation. (Side note: Make sure your vacuum cleaner is a HEPA-sealed model, too.)

Activated Carbon Air Filters

Activated carbon filters are comprised of trillions of molecular-sized pores that have high absorbent and chemical bonding ability.

Activated carbon filters are highly effective at capturing pollutants like chemical emissions, gases, tobacco smoke, and odors. Once captured, these pollutants are not released back into the air.

Activated carbon filters are recommended for people with Multiple Chemical Sensitivity (MCS) because they absorb formaldehyde, which is found in the adhesives used in carpeting, wood paneling, and upholstered furniture. They also trap fragrances as well as many chemicals found in household cleaning products.

Runners Up: Other Air Filters We Like

There are two other air filtration systems that we consider Good Stuff:

Airpura T600 HEPA Air Purifier

The Airpura T600 HEPA Air Purifier employs similar technology to Austin and is mostly targeted towards smoke, so if you’re a smoker or live with a smoker, this is one to consider. They are a bit pricier than Austin’s filters.

IQAir HealthPro Plus Air Purifier

IQAir HealthPro Plus Air Purifier is another filter that meets our criteria, but it is also more expensive than Austin, and made for smaller spaces. Without a doubt, the IQ Air has an aesthetically-pleasing design, but on the whole, we think Austin offers more for less money.

Okay Stuff

Ultra Violet Air Filters

Air purifiers using this technology have a UV lamp installed inside of them. As microorganisms pass by the UV rays radiated from the lamp, cellular damage destroys the microorganism.

Although UV technology is effective at killing viruses and bacteria, it is best used with a filter system ahead of the lamps. Without a filter system, too many microorganisms get shaded from the light by particulates.

Sneaky Stuff

Negative Ion Air Filters

Negative ion air filtering technology has proven to be less effective than others because it simply masks the polluted air as opposed to actually cleaning it.

This type of air purifier does not have the ability to absorb or dispose of the harmful contaminants in the air. The negative ion simply takes the airborne particles out of the air and transfers them to walls and other solid things in the room. When stuck to walls and other surfaces, they have the ability to become re-circulated back into the air. For this reason, I do not recommend negative ion filters.

Ozone Air Filters

Ozone air purifiers produce the gas ozone (O₃). Health professionals have refuted the claims made that these devices are safe, and no agency of the federal government has approved of these devices.

Exposure to ozone may ignite asthma symptoms, and at high enough level can even scar the lungs. Many of the chemicals found in indoor environments take months or years for ozone to react, making them virtually ineffective. Ozone does not remove particles such as dust and pollen. Obviously, I do not recommend ozone filters.
