Looking for ways to protect yourself from Covid-19?You're in luck! Masks can capture viruses and Covid-19. Read about how masks capture viruses here.
COVID-19 Mask Update
At Smart Air, our mission is to provide low-cost clean air. However, COVID-19 has caused a world shortage of masks and factories are now charging higher prices for masks. We have had to increase our mask prices as a direct result. We hate this, and will lower our mask prices to normal as soon as availability increases and supplier prices go back to normal.
Protect Yourself with These Verified N99 & N95 Masks
Use this N99 mask to protect yourself from air pollution, viruses, bacteria and more. We ran tests in a lab in Mumbai, India and found it captures over 99% of PM2.5 air pollution. This N99 mask scored as one of the most effective, lowest cost masks on the market. Choose this mask to protect yourself from air pollution including PM2.5, viruses, bacteria and pollen.

Do masks actually work? Lots of smart, skeptical people question this. Fortunately, scientists have done the hard work for us! Here’s what their data says for the three most common questions we hear at Smart Air.
Do masks capture the really small particles?
This is the easiest question to answer. Researchers at the University of Edinburgh tested different masks by running diesel exhaust through them and measuring how many small 0.007 micron particles the masks blocked. Virus particles are approximately 0.1 microns in diameter. The data shows masks can capture particles over 10 times smaller than viruses.
Bottom line: Test data shows masks capture even the really tiny particles.
Do masks work when you wear them?
This question is tougher to answer. You need a $10,000 machine like this one to test it. Our N99 mask was fit tested in a lab in Mumbai, India and the results showed the mask was blocking 99.3% percent of particles. Bottom line: masks work well even while people are wearing them.

How long do masks last?
Thomas tested a new N99 mask and a mask he had worn for 11 days in Beijing. The new mask blocked 99%; the old mask blocked 98%. This data suggests they last at least 11 days. Not bad! After 2-3 weeks, you’ll probably want to throw the mask away anyway because it gets gross!

Can air pollution masks filter out viruses and other tiny particles?
A study run by researchers at the University of Edinburgh tested the effectiveness of different masks at capturing particles as small as 0.007 microns (ten times smaller than the smallest virus particle). Surgical masks were found to capture 80% of the particles, with industrial masks such as 3M masks and dust respirators capturing over 95% of the 0.007 micron particles.
Bottom line: Surgical masks and industrial masks such as 3M or N95 masks are able to filter out the coronavirus.
Do I need an air purifier in India to protect me at home?
Most air purifiers on the market today cost thousands of rupees, which puts people off buying them. Smart Air’s testing and open-data prove air purifiers are just simple pieces of tech: a fan and a HEPA filter.
