What I've found to be true about the PURE MSK Masks are they are wearable for the whole work day and provide safe and comfortable safety coverage.
Yes, that is correct, PureMSK is not a NIOSH-approved N95 respirator. PureMSK is an FDA-cleared Class II medical device (surgical mask) made of three layers: outer, inner, and a filter in between — and with added performance characteristics. PureMSK is the only US-made FDA-cleared surgical mask that features our proprietary ‘electrospun’ filter (middle layer) that is ultra-thin and breathable while also blocking 96-98%+ of particles down to 0.3 microns. Those results come from NIOSH, the government agency that approves N95s, and which tested our PureMSK back in March 2021. Here is a link to the NIOSH test results:
While PureMSK offers filtration efficiency comparable to an N95, PureMSK cannot be approved as an N95 respirator because our mask uses an ear loop design, rather than head straps. NIOSH does not approve any masks with ear loops, because they believe head straps provide a tighter fit. They are not wrong! But we like the ear loops because they are much more comfortable for all-day wear.
These are the best masks around!
Comfortable and secure.
