I was looking into air purifiers for a mobile purpose (cleaning breathing air while riding bike in city).

HEPA filters will prob. do the trick but I was wondering if there exists silicone sheet thin enough to breathe  through. I know that silicone is permeable to gases but dont know if its 'permeable enough'.
Anyone with actual experience in the field , your comments appreciated.

I'd recommend a cotton mask with a N95 rating or above. Air masks with N99 and N100 rating are better but harder to find. I'd recommend a cotton version because in my experience, they are more comfortable that ones which have the HEPA filters. HEPA filters are good, but in my experience the material was similar to plastic and got a bit sweaty.
