Customer Reviews
3M™ 8511 Respirator with Cool Flow™ Valve is rated 4.3 out of 5 by 6.
Rated 4 out of 5 by from This respirator protects covid This respirator is very good, it protects against covid and has a respirator, but if the person who uses it has covid they can exhale particles with viruses.

Rated 2 out of 5 by from Love the mask, Hate the politics Im confused on why this is considered a good face mask for covid, It literally has a valve that turbocharges the velocity of UNFILTERED air coming out of it. The fact that this mask is considered "N95" only applies to the user inhaling air not exhaling. I use this mask because its the only mask that doesnt fog my glasses when I work and have had to use the same 2 for 8 months now. I cant stand the full respirator that makes a lake of sweat inside. This mask should have never been considered for covid, its kind of mind blowing how Ive seen no one else bring this up, or is it....

Rated 5 out of 5 by from Great features Im looking to buy 280 boxes each month for 12 months

Rated 5 out of 5 by from Great Product - Zero Availability I've been rotating the same 4 or 5 N95 masks for MONTHS when I used to use maybe two per WEEK! When are companies like 3M going to start producing enough masks so they can be prioritized for workers on the front lines of building and remodeling your houses and offices and not just those on the front lines fighting Covid-19 wherever that is happening. Please watch for mesothelioma and other respiratory illness to spike once this whole Covid-19 thing is over OR start making enough masks to go around PLEASE.
