3MP100 Advanced Respirator Filter 2297, 1 Pair, Helps Protect Against Oil and Non-Oil Based Particulates, Nuisance Level Organic Vapor Relief, Mining, Shipbuilding, Abatement, Utilities

The media could not be loaded. After breathing in a bunch of welding smoke, I decided to try a slim respirator. Obviously real safety gear like 3M takes priority over everything else. After seeing all the creative and knockoff options I decided to try a filter swap on my existing 3M Niosh respirator with the plastic pink filters. These were a perfect fit. I didn't notice any unusual smells. I haven't tested them with hazardous air yet but after decades of experience, plus the perfect experience with the pink, I will blindly trust 3M on this.As for welding helmets, the big chunky pink filter is too big. These soft grey filters are perfect and I even have room to scoot the welding hood closer to my face!You're already reading a 3M filter review. You've already decided to not be an internet tough guy. You're going to make it past 55. This is not expensive, send it for the 3M.

Favorite filter for ragweed allergy season. I can actually go to work and not get sick. Since I am severely allergic to ragweed, as my children say, you don't go to the doctor often, and you don't go to the emergency room at all. It worked great for going into my house after a house fire. I could smell the burnt items, but I did not develop a cough or anything. The mask cleans well and did not retain the burnt smell. I tossed the filters and I already have new filters for this fall. It is easier to breath with this filter system compared to a N95 mask, and you can replace the filters. I keep my mask in a plastic bag and usually just use one set for the entire three months without problem. I did lose one filter once, so I keep an extra set for back up. Holding your hand over the filter site did not work as well as the filter!Now I just need a Darth Vader t shirt to wear when out in public......

I'll take their word that it's filtering what it's supposed to. No issues so far.

I found it hard to believe these were P100 rated by how easy it is to breath with these filters. I honestly thought there was a leak until I tested my mask - no leak. You can wear a respirator all day with zero breathing labor. Absolutely the best P100 filter I have used to date from that standpoint. I can’t speak to how well these filter from an analytical standpoint - but from what I can tell from use, nothing but clean air seems to come through them. Zero smell from the filters I’ve used to date as well.

Very easy to breathe through!!! The pink 2097 P100's have too much resistance for me, so I've already ordered 3 sets of these 2297 P100's. I have chemical hypersensitivities and I'm working on a PhD in science (toxicology specifically, ironic, I know), so I have to be in buildings and classrooms near laboratories all the time, and I was hoping these would enable me to continue going to campus. Sometimes they don't seem to do anything, sometimes they just delay my onset of symptoms (chest pain + chest tightness), but sometimes these filters do prevent my symptoms entirely - they even enabled me to be in a house with new paint smell without smelling a thing or getting pain. These filters definitely block out odors really well. And the doctors haven't figured out the mechanism of my sensitivities (I seem to react to low molecular weight compounds, whether I can smell them or not), so I can't really fault the filters much. Overall these filters have given me back some of my freedom and I'm happy with them. I definitely recommend these to anyone who has lung issues and need something with low resistance!!

These are great for all the ozone and smoke from steel mill oil being burned off. Obviously not a solve all, but they're better than the fake pink filters that every Chinese factory makes.

Work great for welding gases

I am involved in remediation and abatement. These trades almost always involve PPE, since it may or will make you sick to inhale some of the items we're working with. That having been said, respiratory protection is essential. There is a disparity between making available proper respiratory protection and whether people will be using it. Also to consider is how quickly laborers will fatigue due to their respirator (additional exertions of having to draw breath through the filter media).The 3M Advanced Particulate Filter 2297 is a step in the right direction over the 3M 2097. I place a high value on employee comfort, as I believe it's tied to productivity. Make it easier for people to breathe, and they can get more work done. Less likely to find them without their respirators, too. OV relief means that you don't have to smell things you're working on. Smells which this has successfully extinguished include: the stench of death (animals and people), the ripe smell of someone who's been wearing a tyvek coverall for a full work shift and most disinfectants and detergents.I bought some of these here for testing, but the price is too high for regular use. Can be found significantly cheaper in bulk (cases of 100 packages of 2 each).
