Pack of 5 N95 masks.

This pollution mask is an N95 respirator. N95 respirators are a respiratory protective device designed to achieve a very close facial fit and very efficient filtration of airborne particles. This mask has been rated N95 by NIOSH.

The ‘N95’ designation means that when subjected to careful testing, the respirator blocks at least 95% of very small (0.3 micron) test particles. If properly fitted, the filtration capabilities of N95 respirators exceed those of face masks.

Each mask lasts about three weeks if used everyday for about 3 hours a day. If you live in Delhi, we recommend you wear a mask every minute you’re outdoors.

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!

    Face Fitting need work.
    In Varanasi, it went blackish inside a week with 2 hours a day usage.

    Not sure it lasts 3 weeks!

      That’s a really good point! We’ve only ever done one mask longevity test, and that was in Beijing (read about the test here).
      Having said that, the mask Tom tested was 11 days old was also turning black yet its efficiency was still fairly high. What normally happens is that these masks get smelly and gross after a few weeks anyway!

    It’s been close to 6 months i am using this mask in Bangalore traffic. I daily ride around 30 to 35 km in heavy traffic and these masks are saving grace for me. These are priced well and each mask can be used for 4 to 5 week depending on condition of masks.
    Only problem with these masks are they are pretty big and covers entire face just leaving enough space for eyes to see the surroundings. Sometimes nose grip becomes very tight if by mistake we tighten the elastic thread more otherwise it serves the purpose very well.
    Without masks i used to get cold and cough within one month but once i started using the masks no more cold and cough and i can feel fresh inside nose even after riding through dusted and dirty roads. I have even suggested few of my friends to use these while riding bike.
    Keep the good work.
