The 3M 2091 P100 (HEPA) Filter is sold by the pair and features extremely fine filtration that traps all but the most minuscule particles. Our customers use them to protect against asbestos and lead dusts in particular, as well as a host of other dusts, allergens and fumes. The filters are extremely lightweight and flexible, and they fit tight against the mask, which makes wearing this type of mask a bit more comfortable.

The 3M 2091 P100 Filters fit on the 3M 6000 and 3M 7500 series half masks, as well as the 3M 6000 full face respirators. HEPA filtration is rated to remove 99.9% of particles .3 microns and larger. This includes most welding fumes (burnt metal), toxic dusts like asbestos and lead, and folks with allergies to many environmental dusts. Sometimes called a 3M P100 pancake filter, they are attached directly to the mask. A simple 1/4 turn locks them on. No retainers or other attachment methods are needed.

This filter is also available as an assembly paired with the 3M 6000 half mask. When bought together, this 3M 6000 Lead and Asbestos Mask is one of our most popular items.

*If the hazard is mold, or if you are arc welding, then we would suggest the 3M 2097 P100 HEPA Filter that has a layer of charcoal. Active mold growth produces Volatile Organic Compounds (VOCs) that won't be absorbed by the 2091. Arc welding produces ozone, which also won't be absorbed.

    3M 2091 P100 Particulate Filter Video Transcript

    Hi! This is Rick Pedley and welcome to PK Safety Supply!

    Today we're talking about the 3M 2091 P100 Particulate Filter. The 3M P100 fits onto the 6000 series respirators, both half, full face and the 3M 7500 half mask respirator. Now, P100 is the current name for HEPA or High Efficiency Particulate Air filter.

    Now, the P in P100 means that it's oil-proof. Now, what's interesting about that is that these filters are electrostatic filters. That is, they have a static charge. This static charge attracts and traps the dust that comes through. So what they're giving you here are two filters. You have both on the mask at one time and they're soft! We call them a pancake filter. They're made of a kind of polypropylene material. They have a little bit of fuzzy stuff inside to keep them from crushing. But they're very comfortable and extremely lightweight. You can put these on your mask and it's easy to breathe through and hardly feels like anything's there. And if you do brush up against something, they do bend a little bit.

    For instance, if I were wearing a welding helmet, this would be a very convenient filter to be wearing. One thing we do want to watch out for when we're welding is sparks. Because it's a polypropylene material, it will burn. And when I say burn, I mean that they'll char. So, if you've got a spark here, it'd put a little hole in it. They will not catch fire. They're self-extinguishing. but that's kind of important. If that comes up, if that's an application you're thinking about, where there are flying sparks… maybe you're grinding metal for instance… if those sparks might hit the filters, I'd suggest using their model 7093, which has a plastic case -- shaped a little differently. But uh, we wear these filters in particular… the big ones are asbestos and lead.

    Now, asbestos… if you're a home owner and you're working on some duct work, maybe you're working on your car and you've got some old style brake linings with asbestos in them, this'd be the thing to wear. It's gonna protect you from that.

    In the case of lead, we have a few different things. You know, lead dust around the house… thinking in terms of grinding paint… anyone with an older home is most likely going to have lead paint on the windows and so forth. Anywhere there's the glossy paint close to the walls… pretty likely to have lead. And then, some people will also burn that off. That is, to remove the paint, they'll heat it. This can be inside the house, this can be outside the house, but these are gonna be good for that. What's important, though, is that you have ventilation, because when you're heating the paint to take it off, you're probably also creating carbon monoxide, which isn't a good thing. Odorless, tasteless… filter's not going to stop that. The other thing is, when you're burning paint, there's also a fair amount of organic material that is going to be generated. Once again, that may not be taken care of by this. There are other filters… if I was burning paint, and I didn't have a lot of ventilation… I mean, you've got to have something, trust me… but their model 60926, which we'll look at in a different video, would be a good item to use.

    So, those are kind of the main uses for it. HEPA filter, though, is good for a lot of things. Anybody who has got severe allergies, this is something to look at. It's gonna stop all but the very tiniest particles… cigarette smoke… it won't get all the odor, but all the particulate in the air is going to get taken out. It's a really interesting filter.

    So, flat pad. Got this little connector in the back and this clicks on with a quarter turn. We looked at that on some of our other videos, so I won't belabor that. It comes in a sealed pack with a pair… you get some instructions, not all that helpful I must say…

    There you go! That's the 3M 2091! Thank you very much!

  1. Back up set Review by DLS of KY

    I ordered the filters as a back up for the half mask I ordered that had them on it already. I am very pleased with the way they kept the saw dust, insulation dust and demolition dust out of ME! (Posted on 11/3/14)

  2. A+ Review by Rob

    I recently was able to convert my civilian Israeli 40mm gas mask to accept 3M filters and was seeking a P100 HEPA rated filter to provide possible protection from airborne pathogens. My order came through exceptionally well. The 2091 filter was exactly what I was looking for and I was very happy with the quality of the product. (Posted on 10/29/14)

  3. Great quality Review by Lizzie

    I have been very pleased with these filters & all of the supplies that I ordered! I can not say enough good things about the customer service that I received! They are awesome! (Posted on 10/6/14)

  4. Worked for us Review by Wild Investment

    We were using filters that were really for fumes and we needed to block out dust and what could have potentially been asbestos. These worked great in keeping and filtering all dust and fibers. Would buy them again. (Posted on 8/14/14)

  5. Will buy again Review by Steve

    Use for construction demo. Feel protected. Nothing negative.

    Hope it is working -- it fits fine and is easy to change out -- using it to filter asbestos, so again -- HOPE it is working

  8. Exceptional filter Review by Micheal Hamilton

    Have used in lost wax cast Bronze Foundry for 10 years. Handles the fine silica dust in the slurry room and external sand blasting, handles metal fumes from pouring and welding, particles from grinding and chasing and most fumes from the patina chemicals. Highly Recommend.


    Newer filter seem to de-laminate faster than the older ones.

    Comments from PK Safety:

    Hi Michael,

    Thanks for taking the time to write a review. We like knowing the 2091 filters perform so well in your foundry work.

    About the delamination issue - we are wondering if you have tried the 3M 7093 filters. The 7093s provide the same level of filtration, but have a protective exterior that might protect the filter better in your work environment.

    They are also slightly less expensive.

    Thanks again for the review, and an extra thanks for attaching the excellent photo.

    Best regards,

    PK Safety

  9. Seem to do what they're suppose to do Review by Dwight L.

    I do woodworking as a hobby. I was asked to make some pieces from Pacific yew. Found out the stuff can be on the nasty side to work with. Marc Spagnuolo, The Wood Whisperer, did a video on the effect of dust on one's well being. He uses these filters in his shop. What's good enough for Marc should be good enough for me. I worked the yew using the filters and did not have any problems is all I can say.

    Can't go wrong with a 3M brand.

    Well--they are pink!

Overall Rating?



  • The P100 HEPA (which stands for High-Efficiency Particulate Arresting) filters trap dust and particles like a strainer. Once the filters have successfully blocked a large amount of particulate matter, they still won’t let that material into your lungs. They do however start allowing less air to past through, and breathing will become more and more difficult.

    You may not notice it at first, but as the filters clog up, it will become harder to suck in a breath. Trust us, you’ll notice eventually. That’s when you know it’s time to replace the filters.
