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. Want to learn more?

Why Smart Air?

Clean Air, No Gimmicks

The air purifiers industry is full of companies that make clean air overpriced and overcomplicated. The truth is clean air is simple. All we need is a fan and a filter.

Big companies don’t make profits with simplicity that’s why they add loads of unnecessary gimmicks to their machines.

Smart Air promotes the simple fact that air purifiers are just fans and filters. By cutting out fancy marketing gimmicks such as ionizers and photocatalytic filters that can actually make your air worse, we’re able to give you more clean air at a fraction of the cost the “big guys” would charge you.

No gimmicks! More clean air!

By cutting out unnecessary add-ons, we’re able to give you more clean air for a smaller price.
See for yourself.

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?

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.

Find in-depth explanations on both filter types here.
