Verified Purchase(What is this?)
This review is from: 3M 4251 Maintenance Free Reusable Half Mask FFA1P2RD -Single respirator (Misc.)
i bought this mask last week: i'm surprised at how efficient - and surprisingly comfortable - it is. i'm wearing it in dusty situations, and it seems to work really well. if you're a claustrophobe you might find it a little disturbing to start with - but you soon get used to it, once you've found you can actually breathe! a tip for spectacles wearers: put the mask on first, then your specs, otherwise you can get the lenses marked as you pull the mask onto your face.
update: it's a really good mask - i've been using it to filter dust from cat litter - but after a while it gets harder and harder to breathe through it: presumably it's become clogged, though you can't tell that from looking at it. as i've only had it a month or two, this makes it quite an expensive mask. however, it certainly does the job.
