This is really helpful – thank you. I have a house that has had some asbestos disturbed. I was planning to buy a bunch of H13 purifiers, but with a 0.7 micron min particle size for asbestos, which is well above MPPS (0.3), I think H11 might be good enough running for a week in an unoccupied building. Can you explain how H11 filters can both be 99.97% [email protected] microns (comforting) but only 95%@MPPS for the EU H11 rating (less comforting)?
Fascinating and informative article! Thanks!
Can you recommend some face masks that might be the best mix of price and performance? I’m currently unemployed and cannot afford the most expensive masks and replacing them every few hours. I realize that’s a challenging request, but any suggestions are welcome. Thank you.
Interested in clean air in schools and ac. rooms
I have TILT. Every little toxin or chemical in the air that everyone else breathes normally, makes me feel sick. Car/factory exhaust, fragrances, laundry detergent, wood stain, carpeting, etc, etc, are especially affecting me. What can I do to help make my air the cleanest possible?
Hi, what about carbon filters? They are about to filter VOC, so does they filter 0.3 AND smaller particles?
