> mouth. It is very easy to put on and take off. Very convenient. On
> this front it does have a slight edge over the totobobo mask.
> 2. It seems to be as effective as the totobobo mask in filtering out
> the sub micron particulate matter in pollution. And in addition it has
> two one way valves on it which ensure that as you breathe out, the
> water vapour in the breath goes out without condensing inside or
> without leaving a temporary cloudy layer on my spectacles. Because
> these are one way valves, when you breathe in, they lock up and the
> air passes only through the filter inside the mask.
> 3. The filter has a Dynamically Activated Charcoal Cloth (DACC) in it
> which adsorbs (note this is not absorption but adsorption) which is
> supposed to protect you from gases like CO and other gases in typical
> vehicle exhausts. I was very keen on testing this aspect of the mask

> mask I can smell the exhaust quite clearly and they anyway do not

> does claim that the mask filters out particulate matter (upto 94% i.e.
> 1% less than the N95 NIOSH standard) upto 0.3 micron size (i.e.
> anything greater than 0.3 micron size).  As I mentioned in my earlier

> 4. According torespro, the filter is expected to last for 30 hours at

> 5. I was of course sweaty inside the mask but surely a lot less than
