Be aware that they no longer include a PM 2.5 filter for inside the mask pouch
I liked this mask which is why I purchased a second one for my husband. Unfortunately this mask is no longer coming with any PM 2.5 filters that the first one came with. That is a big disappointment for me as it means that it doesn't provide the same protection by a long shot. I will have to purchase the filters somewhere else. I'll keep it rather than go to the trouble of finding another big enough but I will not purchase it again.
