Q: Cloth masks are relatively inexpensive. How much do some of these upgrades cost?
Srikrishna: The Envo mask, which I personally have been using quite a bit and fits like a sleep apnea mask, is $79. It’s reusable for three to four months and has replacement filters for $2, and is now sold with a valve cover. 3M’s Elastomeric mask costs about $30 and has filters for $7 or $8, and these may last up to a year. The Fire Department of New York is using them. SoftSeal masks have a gel seal but are still disposable, and they cost between $7 and $16. And Fix The Mask is a flexible brace or harness that you put over a regular surgical mask and it forms a tight seal and provides a really good fit throughout the face. They cost about $15 each.
