Works Great, But These Pancake Type Filters Need a Frame Of Some Kind

For those that don't know, these P100 filters (which is respirator filter spec for HEPA filters), are 99.97% effective against all filter particulates down to .3 microns. I got these specifically for mold, and they are same as the 2097 except do it with only THREE layers instead of the 5 of the 2000 series. I don't notice any breathing restrictions, they really are like not wearing any filter at all! Even though these are only for particulates and OV's, they actually can filter some fumes: In a bathroom with "serious plumbing problems" that necessitate the frequent need to dump bleach on the floor(!), I could barely smell the chlorine (I got the 3M 60929 for that). In a test I wanted to see what they'd do with something like Gold Bond powder (respiratorily toxic to me), and I was also shocked you could barely smell the menthol & other fumes, which is not even an OV. They actually did better against that and the chlorine than the 3M 60923, which is far more restrictive. I use them on a 3M 7503 (a large 7500) mask. The only thing I don't like about these pancake/disk type filters is they are a bit hard to put on and take off since they don't have any kind of a "frame" or "scaffolding" of sorts. It's like trying to screw on a powder puff and you feel like the plastic mount may twist off or rip away from the filter. If they had some kind on a hard internal frame that attached to the plastic mount, or external rear frame, or some kind of "external cage" that attached to the mount, they'd be much easier to remove and put back on. I would think they'd be much more user-friendly and probably more reliable with regards to removal/attachments, if they had some type of frame. I also have to say, that even 3M mentions to put your mask back in the (or a) Ziploc type bag. They don't say to remove the filters! Therefore, all the contaminants that are on the filters' outside, (outside frame, or air ducts with other 3M series), WILL GET INSIDE THE BAG WITH YOUR MASK then INSIDE THE MASK! Imagine if you dropped the bag and all the contaminants that would shake loose and dislodge from the filters that would get dispersed into the bag then get inside the mask! So if you keep your mask in a bag, you REALLY should some way seal the inside of the mask FROM the outside of the filters. You know those microwaveable covers with elastic that you stretch over food containers? Use 2 small versions of those. Small enough that when the elastic in them is stretched you can barely fit them over the filters. This way the filters are separated from the mask's inside.

Works As Advertised

I contacted 3M and expressed my need for a filter that filters out cigarette smoke and dust, as well as odors. They recommended this filter. I use this at work as I am high up near the ceiling of a warehouse where all the smoke, dust and other toxic fumes collect. Work can be fast paced manual labor, so I needed something that wouldn't restrict breathing as well.

Easy To Breathe

Great filter, went perfect with my 7000 series 3M mask. Super easy to breathe through.
