Comfortable fit, excellent air exchange
I purchased three of these masks for my family during this summer's wildfire season, which unfortunately continues to burn only 8 miles away from my home. These 3M Half Face-piece Reusable Respirator Assemblies make the smoke bearable. The fit is snug, but not tight and can be adjusted to fit different face sizes. The feel of the mask becomes more comfortable over time than surgical-type masks, which tend to lack suitable air exchange which holds in vapor (ie: sweat). The filters which are pictured on the side of the respirator (pink in the picture, but we received blue ones with our masks), are easy to attach to the mask. You will need to purchase new filters as these get soiled, but the price is reasonable. Notches on the respirator correspond with those on the filters and it's a matter of lining them up and twisting them on. The connection is very secure and the filters do a great job. These respirators are superior to the basic paper face masks, and obviously work well enough to be used in multiple situations, for multiple uses. I would recommend these masks to anyone who needs a step above the basic filtration that a 3M 1860S Particulate Respirator and Surgical Mask, Small, Box of 20 provides. People with asthma, COPD, the elderly, children and those with autoimmune diseases would benefit from using this mask in smokey conditions. Under normal circumstances, those who are into crafting and woodworking, using sanders, paints, and varnishes, would also find this respirator assembly a helpful safety basic. These masks do come in sizes (S,M,LG). I purchased 3 of the medium size, and it seems to fit everyone (all average sized 5'4-5'10, average weight), just fine. I highly recommend this quality 3M product.

Comfortable on
I bought this to use while I mix jesmonite and it works as expected. Seems to filter particles well and is comfortable on. A bit of a weird strap but I’d recommend it.

Breath of Fresh Air - Awesome!
I'm a photographer with a varied style and subject matter, including rusty, dusty abandoned locations. With being highly allergic to dust and other fine air-borne particles (we're talking sinus infections within a day with little exposure), and working around potentially dangerous substances, I needed a respirator that would fit well, get me into the locations with confidence, and keep me safe. I tried a few disposable masks which worked well and kept me from sinus infections. However, buying a new one for each location became too costly, and sometimes, they're hard to find. I didn't want a full-face mask that might obstruct clear view of my camera settings and other equipment, plus I wear glasses, and admittedly am a bit claustrophobic. This mask is the perfect solution. It fits securely over my nose and mouth. It's lightweight and comfortable to wear for the hours I spend on location for my photography and it filters out all the potential nasties that I could come in contact with. I haven't had a sinus infection since using this mask. Being rated P100 for asbestos, I am confident that it will also filter out any essence of vermin and critters in the locations. I wear it slightly lower on my nose so that I can also wear my glasses without difficulties. When I'm done shooting, I simply remove the filters and discard them and wipe out the mask. It does collect some condensation after breathing in it for so long. I let it air dry before storing it back in the ziplock bag, which keeps it dust-free between uses. I'm very happy with this mask and recommend it for anyone who is in contact with, or who is highly sensitive or allergic to, potentially dangerous air. This mask is NOT rated for vapors, fumes or pharma use. Make sure to know what the proper ratings are for your specify use.

Great-fitting mask for me, make sure you know your size though
I've been fitted for a respirator at work, but wanted to use this as an accessory for my Jesse Pinkman (from "Breaking Bad") costume for Halloween. I can't obviously take supplies from work, so I had to buy my own someplace, and as usual, Amazon had the item I needed at a great price with Prime shipping! This mask requires you to install the pink filters separately, which is quite easy to do. Just push and twist a quarter-turn. Then you adjust the straps so it fits on your face snugly. The particulate filters that come with this mask are only rated for keeping out dust and other airborne debris. Further on that point-CHECK THE FILTER: these filters will NOT keep out organic vapors (like paint fumes), you will need to get the canister style filters, and be very certain you know how to fit this mask properly at that point. A good fit test is to put your hands over the filters firmly and breathe in: if the mask "sucks in" around your mouth and nose, you likely have a good seal. If you can feel/hear air coming in around the mask, you do NOT have a good seal and you'll still be breathing whatever contaminant is in the environment. As for the sizing: I'm a man, 5'9" and 180 lbs, but my face is fairly narrow, so this size worked for me. If you have a larger/fuller face, you would probably need the Large, and if you're very petite/slight built you would want to try the Small. Note that the packaging is not resealable, so once you've bought it, it's yours!

Great product!
I bought these back in January but still wanted to leave a review. Great product and great seller. I bought these for my family and loved ones to use especially during this time period but also to do wall work. It has greatly helped to keep my family's lungs safe from debris. The fit is good you have to just work on the straps and make sure that the mask sucks in so that there are no gaps so that the fit is right. What I'm really happy with is that it came with the P-100 pink filters for each mask. I am a petite 5'1 woman with a relatively small face so the medium size did not fit me I then purchased a small. The medium sized masks fit the men in my family well even though they have different face / nose shapes and it fit my boyfriend who is tall. I do find that if you have a very protruding nose bridge this mask might still be uncomfortable even though it is known to be a bit more comfortable than other masks. When considering to use this for prolonged use I recommend that you will have to just give it a try. I believe it will fit nicely for most people now if you have a larger more prominent nose/nosebridge it will . I'm very thankful to the seller thank you for getting back to me with my questions. I received the masks early.

Not as described, no customer service
At this point I cannot recommend this product. I ordered the 3M P100 Half Facepiece Respirator 6000, which, per product description includes two filters. I did receive the respirator in good time, however, the interior packaging from 3M was open upon arrival and no filters were included. Because of the nature of this device it cannot be returned. I've attempted contacting the seller multiple times with zero response. I've tried calling their help line and am shuttled through a "system" which leads to a dead end. If I am eventually satisfied with this situation I will update my review. But for now I say "buyer beware".

Parece usado
Parece que alguien se lo puso antes porque se ve grasa alrededor de la mascarilla. Usualmente esto se ve así por el contacto del rostro. La bolsa no viene sellada, es tipo ziplock pero ya venía abierta. Pésimo control higiénico para un producto de uso personal.

NO INCLUYEN FILTROS
Dice que incluye respirador y FILTRO de partículas 2091 los cuales NO LLEGARON CON EL PEDIDO. Por el precio uno llegará a a suponer que incluye filtros, ya que existen las máscaras sin filtro de la misma marca al menor precio!!!
