How Air Purifiers Trap COVID-19

A common concern is whether HEPA filters can filter viruses like the COVID-19 coronavirus. Science proves, air purifiers that contain HEPA filters or even lower grade filters can capture virtually all sizes of solid particles, including particles 0.06 to 0.14 microns in diameter – or the same size as the coronavirus.

Are Smart Air purifiers better than other air purifiers?

Our air purifiers work on the same principle as any other brand’s air purifiers. However, we’re the only air purifier company in the world that is transparent with its data and that doesn’t deny the fact that air purifiers consist of little more than fans and filters. We don’t make air purifiers overcomplicated and overprized by adding useless gimmicks to them. Our machines are honest, fully data-backed and streamlined to do one thing: cleaning air. And they do this one thing really well.

Do Smart Air purifiers filter the coronavirus (Covid-19)?

HEPA filter air purifiers like Smart Air’s have been shown to filter out COVID-19 viruses, and lower transmission. See the data and learn how to protect yourself now.

What else do Smart Air purifiers filter?

Our HEPA filters capture all kinds of particles ranging from 0.005 μm (nanoparticles) to 30 μm (pollen). This includes virus, bacteria, PM2.5, PM10, pet allergens, dust, and mold.

Our Carbon filters absorb VOC’s (Volatile Organic Compounds) such as formaldehyde, paint thinners, petroleoum fuels, or dry cleaning agents. Carbon filters also remove odors.

Of note: Not everyone needs carbon filters that’s why all our air purifiers come without them by default. We want our users to decide by themselves if they want carbon or not.

How long is the warranty?

We provide 2 year warranty on all air purifiers for manufacturing defects. 1 year warranty applies to our air quality monitors.

Are Medical Grade Air Purifiers Required For Hospitals?

No. Turns out, the term medical grade air purifiers are more of a marketing gimmick than anything else. Normal, HEPA filter air purifiers can filter viruses.

Are air purifiers with UV-light and Ionizers required for hospitals?

These again are marketing gimmicks to get you to purchase a more expensive purifier. UV light air purifiers are too weak to kill viruses quick enough and can damage HEPA filters. Ionizers are also too weak to make a difference, and can produce harmful ozone.

How many air purifiers are needed to filter the coronavirus (Covid-19)?

The CDC recommends 6-12 air changes per hour when dealing with viruses or other airborne infections. Therefore, the CADR rating (given in cubic feet per minute or cubic meters per hour) of the air purifier should be at least six times the volume of the hospital area being used in.
