Keep out 99% of PM 2.5 with this comfortable Venus mask. This Venus mask is rated FFP3 and conforms to the EN 149:2001 standard, which is equivalent to the N99 NIOSH standard.

This mask should last for 2 to 3 weeks with around 3 hours of use per day in Delhi, or until it gets smelly enough that you’ll want to throw it away!

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!

    Just picked up a ten-pack of these from your Lado Sarai office.

    * Breathing is easy and comfortable, I think one could even use these while cycling (though I have not tried that).
    * They fit over the face and mouth well.
    * They can be worn under a full-face motorcycle helmet.
    * They don’t get hot or sweaty, even in warm Delhi conditions.
    * A bonus for people who wear glasses: the nose clip seals snug and comfortably with a press of the fingers, so that exhaled breath will not fog up your glasses. For me this was a major concern as I wear glasses and also ride a motorcycle with a full-face helmet, so it’s always a pain with either the glasses or the visor would steam up. This mask is designed well enough that this does not happen.
    * Absolute value for money.
    * If you live in Delhi and are in a rush to get these, you could order and pick them up from their office (the option is there at checkout) to save time.

    I’ve tried other masks at this price range and usually you wouldn’t be able to get all these features in this price.

    * None.

    I bought a ten-pack specifically to hand out to friends and family in hopes they will be more aware of how polluted the air in our city is and start taking precautions.
