COVID-19 Resources


Watch out for counterfeit masks: Buy from the manufacturer or from trusted resellers (not Amazon). Here are some particularly useful recommendations:

3M V-Flex N95 masks. Good for breathing and speaking easily.

GVS P100 mask for extra safety. Roomy for breathing. Great seal. "Bane" aesthetic. Also good on smoky days.

Flo Mask Pro. Designed for a comfortable fit and a wide, easy-breathing filtration surface.

ReadiMask. Strapless and metal-free. Great seal. Can be used in an MRI, or inside a costume.

Mask quality means nothing if you breathe around it. The quality of the seal to your face is paramount! Quantitative Fit Tests measure mask leakage, which mostly involves how well it seals. When you read these histograms, a large volume of results to the right (in the green and silver range) is good. A significant volume of poor results (red and orange) is a warning of poor seals. That said, if you can tell how well a mask seals to your face in particular, that is more valuable than average results. Masks that do particularly well include 3M Aura 1863+, 3M Aura 9321CN+, Dräger 1920 small, Trident RTCFFP2 S, Trident RTCFFP2 XXL, and Zekler 1502 small. Avoid the 3M AFFM (commonly sold at pharmacies), which is not a NIOSH approved respirator.

N95 masks were designed to fit an average, male, American face. KN95 masks, often considered not quite as good as N95, are designed for Korean male and female faces. If a KN95 seals well and fits you better than an N95, then it is the superior mask!
