I bought this mask for protection from dust and mold encountered while doing household projects. The exhalation valve helps to reduce fogging of my glasses in cold weather. I am pleased as it is more durable than simple fabric ones. I did notice there is a small increase in effort when inhaling. This is common for masks that have good filtration but could bother some users.

Outdated, not allowed on planes or hospitals without additional covering. Must not have facial hair that breaks seal or not worth it. Keep spare cheap slip over cover to put over valve as needed. Likely much better protection than home made if worn properly. Rotate mine on 7 day cycle in zip locks so covid has time to die before next wearing. Nothing is fool proof but combined with keeping a closed bubble with minimal contact with those outside it has kept me safe. New designs have no valves but are likely harder to exhale through. This design may be relegated to the dust bowel of history so priced too high for old model in my opinion from what I paid. Got me RT ✈ E-W coast without covid during open center seat.

The durability and facial fit & seal seem excellent, and the suction when I inhale very clear. After a day of use I sanitize it with an alcohol spray. I also use a 1" wide elastic headband to hold it on rather than the elastics. The elastics are not adjustable and very tight on me (6' and 180lb), and so not easy to put on or take off.

These have an expiration date on them. Shelf life After manufacture is FOUR years. Some sellers are selling very old, expired masks that will probably not protect you. So buyer beware. Check your expiration dates! They are comfortable. Just be sure they are not expired.

This is a pre-formed mask that will fit well on most faces, but be aware that the nose piece cannot be spread for those of us with broader nose bridges. It will pinch and cause you to breathe through your mouth. It is otherwise comfortable, and well made, and the valve works well, as opposed to the 3M mask valve, which does not.
