3M P100/OV Odor/Particulate Multi-Purpose Reusable Respirator 65021, NIOSH-APPROVED Organic Vapor Cartridge, Medium

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 purchased the 3M reusable respirator in a medium for use while working on my resin projects, particularly when dealing with particles created during sanding and other cleanup work. The medium fits my face comfortably, even though I have a smaller face. The adjustable straps around the head and neck make it easy to get a secure, customized fit without feeling overly tight. I was also pleasantly surprised by how lightweight it feels once it’s on. The mask has a sturdy, well-made feel, but it isn’t bulky or excessively heavy. I also like that the filters/cartridges are replaceable, making this a much more practical option for continued use rather than constantly purchasing disposable masks. So far, I’m very happy with the fit, comfort, and overall quality. If you work with resin or do projects that create airborne particles, having a properly fitted reusable respirator is definitely something worth considering.

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.

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

This product works great. Highly recommend!

The box was crushed, and the package should shipped in a box not in a bag. Good thing did not damage the filter cartridge. The face mask fits ok, straps are bit flimsy and not sure it will last for multiple use. I guess you're buying only the filter/set for a single job.
