These masks don't look like they'd be effective. There's no mention of a "meltblown" layer. Plus, it's manufactured by a completely unknown company and being sold by an unknown merchant.
There are much better alternative available. Here's a few good sources for respirators:
- Powercom KN95 [bonafidemasks.com]
- TIA BOTN [behealthyusa.net]
- Dr. Puri (blue only) [behealthyusa.net]
For surgical masks (the real ones at least) it's difficult to find a reliable vendor that sells to the general public.- Manufacturers such as Halyard (Kimberly Clark) and Cardinal are well known.
- Insist on ASTM certification [astm.org]. Here's a good explanation [crosstex.com]. (The quality of this brand is unknown, but the info is good).
- At the very least, the mask should have a "meltblown" layer (not just "non-woven").
- These Level 2 masks look good, though I haven't tried them myself. Made in the US too: Armbrust [armbrustusa.com] (they have a Black Friday deal too).
TLDR: these don't look very effective.N95 > KN94 or KF95 on FDA list [fda.gov] > real ASTM [astm.org] surgical mask > everything else (better than nothing)
