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.

Why is Smart Air a Social Enterprise? And what is a B Corp?

In 2013, we set Smart Air up as a social enterprise. That means we’re not driven by greedy investors who are looking for huge profits, but by a mission to protect people from air pollution. Since 2018, we’ve been independently verified by B Lab for our social, environmental performance, transparency and accountability. B Corps are businesses that meet the highest social and environmental standards for people and the planet. See our impact score here.

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.
