3MP100/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.

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.

Great product. I wear it while cleaning my shower room with a bleach solution, I don’t even smell the bleach while wearing this mask. Highly recommended.

Used it with bleach and it worked perfectly! Couldn’t smell the bleach at all. Felt very protected.

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.

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.

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