3M P100/OV Odor/Particulate Multi-Purpose Reusable Respirator 65021, Medium Size, NIOSH-APPROVED Organic Vapor Cartridge & P100 Rated Filters, Flexible, Thermoplastic Faceseal For Comfort (65021H1-DC)

Excellent mask. I purchased this for my job (greenhouse worker) and I have to mix soils for different projects. When dealing with perlite it can send up such a fine dust it will coat your lungs and prevent the alveoli in your lungs from converting oxygen into the blood stream potentially deadly so we are required to wear masks. I bought this one for myself and am not at all disappointed. No issues with particulates, no coughing like crazy, easy to breathe with, nice fit to my face with proper adjustments which they have an insert to show you how to properly adjust it to your face. When I am walking and just need it to be carried the straps that conform to the back of my head release slightly in the front so they can’t be damaged so I can wear it around my neck as I don’t have an free hands when I am pulling a large crate on a pallet jack to go to the soil mixer. Moisture will build up the longer you wear it I simply make sure that as soon as I don’t need to wear it that I use an alcohol pad (find them at any pharmacy store) and wipe down the inside to ensure no bacterial growth.

Worked great. Fit well. Easy to adjust. Didnt make it dificult to breath. I walked away from refinishing a large cabinet with out sawdust and stain affecting my breathing.

I just received this today, new in box and in good shape, assembled ok, seals good and seems to work as expected... no more flimsy paper masks!Just to clear up confusions in previous reviews, the date on the filters (blue circle) is the "lot and manufacture date" and the date on the filter package (red circle) is the "use by" expiration date, so mine were made this year and are "good" for at least 5 years. Also I am average size (5'10", 170 lbs) and the medium fits perfect and I CAN use my glasses with this mask. Tiny and gigantic folks should order accordingly.... Hope this helps.

Need a mask with P100 and OV for air painting. It fits well.

I like the product. I got it for cleaning our basement after an anti-microbial agent was sprayed and the product caused a reaction for me. I was able to spend hours cleaning in the basement with no issue. I was working in a stinky environment with very strong smelling vinegar. Once the mask was on, I could not smell anything! The filters do restrict airflow. So, I found I needed to take a break about every 20 to 30 minutes and remove the mask. The only issue was the instructions. They are extremely confusing and written as if the product is purchased (or delivered) in completely separate pieces. However, the mask came almost completely assembled, so I only needed to follow the last direction.

Great seal, size is adjustable and fits me perfectly. I have used it for months and it is good as new. I don't notice the weight. It is very durable, I haven't had any change in quality. I can't recommend this enough, I can't smell a single thing through it.

I haven't used something like this before, so this was my first time. I was a little confused trying to put it on at first, but I got the hang of it. Without the filters, I wasn't thinking I would be able to wear it without breathing troubles. However, once the filters were in, it wasn't that hard to breathe, and the Darth Vader sounds greatly lessened. I didn't smell much at all of the chemical I was dealing with. Once you realize how they go on, the filters easily snap on. It wasn't like you had nothing on at all, breathing wise, but it wasn't as bad as I was expecting.I ended up cancelling an order of a N95 mask and upgrading to this one from the concerns I read of the N95 not being good enough for the chemicals I was dealing with. I'm happy I made the upgrade, and it was reasonably priced.

Bought so I could use contact cement and spray filler on my 3d prints. Fits very nicely on my face and keeps me from feeling light headed.The filters are great. I don't smell any of them chemicals and I feel better and safer after use.
