This mask is well made. It does fit over glasses. To wear this mask like any mask one will have to adjust it to fit and seal properly. I had no problem breathing through the N95 filter. The mask is hard to speak through though.
The filters arrived quickly there was a bit of a delay with an earlier order maybe the masks are to popular but eventually everything arrived.
So I’m happy with the product. The mask is more comfortable than the 3m duel filter makman es but it takes more effort to inhale with these than with a 3m mask which uses rural filters. This is probably the price leader for full face masks. I use it from time to time when shopping but also have a 3m full face mask and a welding PAPR mask as well.
