Who knew wearing a mask can be so nice

Love the mask! It sits really well on my face and there's no trouble breathing or talking through it. Best mask I've had so far!

Fantastic product & service!!

This is my 2nd lot of masks & filters: I bought 2 med Merino, 1x med black cotton, & 1x lg cotton print (as it was only size left). Really good value for the extra thought that has gone into behind-head strap design. Merino, even with filter, is comfy to breathe thru, my daughter prefers the cotton & has worn it a lot. Do have to get correct position with glasses; found large (I altered strap) was actually better: right under eyes with glasses brought forward slightly, & make sure strap is 1 up/1 down around ears to avoid slippage. Both merino & cotton have a good seal once fitted- can tell air is actually coming thru mask, not sides, so peace of mind at Level 4 shopping. Extra helix filters bought on special this time.... Everywhere else has for $25 for 7 filters also, but even at regular price (mask & filter pack) makes $10 for a superior design mask well worth it. Ordering more soon Thanks Liz!
