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.

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, and the results showed the mask was blocking 99.3% percent of particles. Our tests from Beijing and published scientific studies found similar results. 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!

    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.

    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. 🙂

    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 🙂

    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.
