3M P100/OV Odor/Particulate Reusable Respirator Medium Size, NIOSH-APPROVED, P100 Rated Filters, Flexible, (65021H1-DC)

Great mask! I've been able to comfortably wear this mask for over an hour while working on pottery. Seems to have good protection from the dust and airflow is smooth. I was able to adjust the straps easily for a nice fit - they also have some stretch for comfort. Only downside is having red marks on my face after longer uses.

I bought this for a month-long rotation as a medical student on forensic pathology. We observe several autopsies every day and depending on how long it took for the body to be found, the smell can be really overwhelming and intolerable. I wasn't sure how well this mask would realistically work to block out that kind of a smell, but the day I got it, I put it on and I tested it on my trash bin and even the dumpster downstairs. I couldn't smell anything. Then when I went into my rotation I discovered that the mask really worked perfectly--it went above and beyond what I had expected. I'm so grateful that I decided to buy this because it immeasurably improved my quality of life while on the forensics rotation. It's very easy to breathe through with no weird plastic smell. You get a bit of a red mark or indentation on your face after wearing it for a few hours, but this quickly goes away. The straps don't pinch or hurt at all. And both of the straps are adjustable so that you can ensure the mask fits your face perfectly, which is important to make sure that you have a complete seal over the nose and mouth. Make sure that you pay attention to the kind of filters that the mask has if you're looking to buy a similar sort of respirator. I bought this one specifically because it has filters tailored to organic solvents, which was suitable and appropriate for my work in the forensic autopsy rotation. But depending on what you're trying to filter out-- if it's particulate matter or asbestos-- you need to ensure that you're getting the right kind of filter. Not all of them protect against every substance equally. But, overall, for the price I would absolutely recommend it, regardless of if you're trying to protect yourself from a smell or some kind of heightened medical risk from exposure to particulate matter at work, it's really a great price for a device that works exceptionally well.

I recently purchased the 3M multipurpose mask for a home renovation project and it’s been a total game changer. I used it while stripping paint and working with strong adhesives, and it effectively blocked out both dust and the intense chemical odors that usually make me nauseous. The fit is snug but comfortable — the adjustable straps and soft face seal make it easy to wear for long periods without irritation. Breathing feels natural, and I didn’t experience any fogging with my safety glasses, which is so helpful. If you’re doing any sanding, painting, cleaning with chemicals, or even just sensitive to smells, this mask offers excellent protection. It’s durable, reusable (with replaceable filters), and feels like a professional-grade piece of safety gear. Definitely worth the investment for both DIYers and anyone who values clean

Used for home repairs and cleaning less than ideal situations. lol. The face piece is soft and comfortable. 3m filter quality is adequate as long as you get the filter you need. The design is easy to put on and off with a simple snap in the back. Breathing isnt terribly restricted but if your very active while wearing it you’ll notice the restriction.

Great fit and works really well! Definitely worth the money to protect yourself.

I bought this when my husband had to go get mothballs out from under our house. Getting the two side pieces on was a little difficult, but it works pretty well. He didn't smell the mothballs at all until the respirator slipped a little. I'm going to deduct a star for that and for the difficulty of the instructions. Overall, it seemed a little heavy but the filter seemed really good. It helped my husband get an otherwise impossible task done.

I bought this respirator to provide protection against dust particles from repairing a large amount of drywall in an old room. I was working heavily with joint compound. A vast amount of dust was created, but this respirator worked exceptionally well. The strap is strong and, while I wouldn't exactly call it comfortable, it was easily adjustable, secure, and fast to take on an off. It was easy to breathe through and greatly minimized the amount of drywall dust I inhaled. I also used this while repainting a room and I found that it greatly reduced odors. Bonus: The filters are replaceable so you can reuse the respirator many times. Overall, this is a great piece of PPE for the big and messy jobs around the house.

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.
