Great and comfortable mask we’re all day long going to buy more.
We love these. We bought for the whole family and extended family because the are comfortable and easy to breathe in.
The mask fits very well and secures a PM 2.5 charcoal type filter inside the filter pocket without problem. We have found the mask a little more flexible and comfortable with our own special cloth filter material we have cut, as the cut filter material will wrap around the nose better, but the trade-off there is the cut material doesn't filter quite as much. However, the cut filter material can be boiled for 5 minutes, dried, and reused, where the PM 2.5 filters we have must be thrown away at a certain point.
This mask fits well and it’s great that there is a built in option for a replaceable filter.
Good looking mask, covers nose & mouth comfortably, but the ear loops need to be larger, or adjustable, because my ears are pinched forward. Not uncomfortable unless I wear for a long period of time, but looks weird.
