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.

How long is the delivery?

Usually, we’ll deliver all orders within 24 to 48 hours (except Sunday) across Thailand. Longer delivery times are rare but may occur.

Can I get a tax invoice for my order?

Sure. Just leave us a note on the checkout page. Tax invoices will be sent separately via EMS.

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.

What’s the lifespan of the Blast and Blast Mini HEPA filter?

We made several tests in Beijing and got the following results: If the Blast Mini is used for 8 hours everyday in an 100m² room on the lowest level, the filter can be used for 13 months (or 3,120 hours). If it is used on the highest level, it can last for 12 months (or 2,880 hours).

If the Blast is used for 8 hours everyday in a 140m² room on the lowest level, the filter can be used for 22 months (or 5,280 hours). If it is used on the highest level, it can last for 19 months (or 4,560 hours). Do determine its lifespan based on usage and location. In Thailand, the life span should be longer due to less air pollution (15-17 months Blast Mini, 22-27 months Blast).

Some big purifier companies claim that their HEPA lifespans are the same no matter which country you are in, but how can it be the same when the air quality differs so greatly in different parts of the world?

Why Is the Blast and Blast Mini so quiet?

Our team of engineers conducted extensive research to design a motor, fan air duct, HEPA filter and front panel to maximise performance while reducing noise. The main reason why our purifiers are so quiet is because the air is flowing through a large area rather than a small area. As an analogy, if you blow air through a large straw, it is quieter than blowing through a small straw.
