MIRA SAFETY M Certified Facial Gas Mask Respirator - Full Mask 1 Year Manufacturer Warranty (CM-i01 Black)

Cannot wear with ballistic helmet, very comfortable and good visibility. Easy to use

As a woman, finding face masks that fit a small head is difficult since all advertised photos and reviews are of men, who have larger heads typically, so this was a gamble since you can't return this mask. The fit is mostly okay. For my fit reference, the length from top of my forehead (about 2" past my hairline) to bottom of my chin is approx 9.75" and from ear to ear (including over nose) is approx 11.25". Circumference of my head is 21.5". If you have a small face, you'll need to pull the straps tight and be mindful of the fit under your chin. It's difficult to wear with glasses (especially wide frame glasses), so if you have contacts I'd recommend wearing contacts for the snuggest fit. Overall not bad. It should do the job in case of emergencies, which hopefully never happens, but it's good to have just in case.

Very comfortable mask. Works very well when wearing glasses. Great value for the money. Excellent fit.

Generally speaking this is a well built mask, comparable in quality to name brands such as 3M or Honeywell. Takes universal 40mm filter and fits the face quite well. However there is a serious flaw with this model and it’s due to the fact that it’s designed and made differently than any other respirator on the market regardless of price. Usually full face respirators would have a two-chamber construction, on that covers mouth and nose, and the other covers the eye. Upon inhaling, fresh air would enter from the filter and pass through a non-return valve from the eye chamber to the nose/mouth chamber, clearing up any foggy or humid air in the way. And when exhaling, the valve would prevent hot humid air to go back towards the eye chamber but to exit directly from the mouth chamber. There is no such valve in this mask, so whenever you exhale the hot air would rise and fog up the entire visor. Their marketing claim is that they employed a super low resistance flap that would allow the hot air to exhaust directly from the mouthpiece and to breathe in easily. In theory it might’ve worked, but in practice this is absolutely not true. Once you use the mask for a while and the antifog layer is used up it becomes completely unusable. It’s also funny to see that their higher end models respirators all having the non-return valve and being marketed fog free design as well. So why they they attempted to fix something that wasn’t broken? Respirators have been working for decades with the non-return valve design. So it’s either a really messed up design, lack of real world test or they intentionally crippled this model for being the cheapest tier in their lineup.

ICE didn't come to my town yet, so I didn't have to use it in combat, but up in the attic, it's great to see out of with just the dust filter attached. It doesn't come with the added filters, so be aware of that, but it's really comfy and you can see well and breath just fine, it sealed perfect, and mine didn't fog up like I saw others commented. Maybe they should stop smoking Meth in it, I did !!! It seems well made so I'll assume it'll last for a long time, or a short time as I fear a nuclear shower may be a bit on the radar in these times of great fear and war planning. Who knows, maybe I'll still have an attic to visit if I'm wrong, which will be great !!!!! (Yes, my comments are written with humor, but also with an honest star rating, so hopefully you enjoyed...lol)
