Jeremy Rutman Posted September 7, 2019 Report Share Posted September 7, 2019 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.

Harry80 Posted December 17, 2019 Report Share Posted December 17, 2019 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. Quote Link to comment Share on other sites More sharing options...
Andika Dinata Posted July 30 Report Share Posted July 30 So you find out kind of mask or you just confuse choosing filter for purifications ? I suggested you wear double mask , layer one is surgical mask and second layer is cotton mask. For outdoor activities such as riding bike you only have single mask for easy breath . And never push so hard while cycling . Nazeer Iqbal 1 Quote Link to comment Share on other sites More sharing options...
