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?

Different mask effectiveness

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% percent of particles.

Bottom line: masks work well even while people are wearing them.

How long do masks last?

How long do air pollution masks lastThomas 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 N99 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.

    I live in Faridabad in Neharpar area which has pollution and dust all through the year. It is difficult to breathe easily. I have been using these N99 masks for over a year now, and once I was able to adjust to them, they have made me breathe easy. I also do not get insides of my nostrils blackened. The mask are well made and cover your face well. You can use them repeatedly without any problem. HAve also bought for my wife and daughter.

    Bought 5 of these as I was traveling internationally during the vivid scare. While didn’t actually use it during the travel, used few later when the air quality was bad. Masks were great and comfortable. Really cheap for the quality.

    Really good masks, i find they last me several weeks, with the vent to let expelled air out, they dont get too hot and are comfortable for long drives to avoid smoke and dust.

    I have been using the N99 mask for 6 months so far, and I must say, am very impressed with how it fits and doesn’t suffocate me when I wear it.

    Perfect for riding a cycle. Low air resistance and a good seal.
    The straps to tighten the mask are extremely easy and quick to use. I believe it will fit most people perfectly by tightening it.

    Please don’t change a thing about this mask! Ok maybe color 🙂

    Very good mask. I ride a Roadie and have absolutely no problems in breathing in and out quickly through this mask. I deduct 1 star ONLY BECAUSE it isn’t as good looking as, say, a Vog Mask. 🙂

    The first impressions of the N99 are very impressive.The most noticeable difference when compared to the other masks is of not being suffocated while cycling uphill sections. The fit and seal is commendable and i hope the straps could get a little better over the course of development.
