I have two of these and they are so-so.
The idea here is not really for allergan filtration it seems as much as large particle issues/big dust/contruction maybe?  Unsure, but i suffer with mast cell disorder (my allergy system is dysfuntional and I have a lot of triggers basically....like angioedema and sysemic anaphylaxis stage cascade...though I never get to shock).  Anyway.  i went to a ladies group that I attend and the girls forgot to not wear their perfumes after the holidays and while this may have helped.. I still had a complete reaction by the time I got home.  I love the look of these and they are much less offensive than other masks that I've worn and so I am happy to try the N95 masks now, but I honestly would love if the company would give me a credit or something...  especially since the N95 filters are not replaceable and I will have to pay 30 bucks every  450 hours of use anyway.  I'd kinda like my 60 bucks for these two organic masks back.  I only gave these three stars because I respect and appreciate the company for making these for ppl like me, so much.  There's no other company out there making masks that look this nice and that means a lot to me.  Otherwise, these organic ones rate 2 stars for me.
Rating: 3 stars
