How is this item different from the "3M 2091 P100 Particulate Filter"? Both appear to work with 6000 series respirators and are P100.

The 7093B is enclosed in a hard shell, and air is drawn from behind the cartridge near the face. It's useful for welding, or other scenarios where a soft 2091 could get damaged.

Different casing and method, this uses a pleated media, the 2091 uses a loose-woven-type media. Functionally? This one offers better protection to the filter itself (as previously mentioned, particularly from welding sparks) and is easier to leak-check thanks to the push-down seal function, but they both provide the same filtration.

The use of the 7093b is for water decontamination; the plastic shroud protect the filter media from water when you wash the person down. The 2091 is not designed to get wet or be exposed to water Decon

I have found that the 3m ones seem to last longer and provide more filter action, even though they are rated the same. I get the 3m ones, because I deal with spray paint in my art and it's very bad if you inhale it. The difference is not big between these two, but safety is important.

To keep dust and mold out of my system I used the pink circle filters (3M Tekk P100 Particulate Filter with Nuisance Level Organic Vapor Release) and it worked wonderfully--much better fitting and much better working than those disposable masks. If you have allergies or asthma or got really irritated lungs/nose/throat the last time, I would recommend this for the next time.Others have mentioned more detailed specs on the 3M website. (Your second question, I don't have a response for.)

Recommend you use the 3M 2091 Particle Filter which will do the job equally well for dust and save money; both filter types must be replaced when used up.

You must be in Shanghai or another city in China too. My husband's employer's HR department recommended the 3M N95 masks. I am using them and I truly hope that they are effective since the AQI here has been around 500 yesterday. I think PM2.5 hovered at about 300. Wish I could give you a definitive answer. I do notice a difference between when I am wearing a mask and when I forget to put in on.

Yes - Anything with a P100 filter is an excellent choice to protect against air pollution (It's probably overkill). The P100 filter eliminates 99.97% of particles greater than 0.3 microns (Air quality is measured per the concentration of 2.5 micron particles). P100 is a superior standard to the N95 masks that are widely advertised for air pollution. Furthermore, the "P" rating means it filters oily particles, so there is additional protection against wood smoke and diesel exhaust. Of course you must choose the correct size to make a seal with your face (having a beard will interfere with the seal). I'm a slender adult male and the medium in this 3m 6200 series fits me well.

It depends on what you're doing - I got this filter because it seems to be pretty all-encompassing: 3M Low-Maintenance Multi Gas/Vapor Cartridge, For 6000 and 7000 Series Air Purifying Respirator (Pack of 2)It's been effecticve for fiberglass insulation, sanding plastics and composites, spray painting, etc.

They filter particles as low as 4-5 microns. When I was in S. Korea I observed people wearing dust mask and these 3-M mask and filters are 1000 times better. Also the mask fits closer to the face with not gaps/openings.Loyd

It should help. N95 filters are recommended but these filter out more particles. But I don't use the filters for that purpose, you could double-check with 3M.

This particular machine requires two different filter sizes because there is a small filter in the wand and another larger one on the vac output, these work to block the shredded skin cells... my machine really works well so my filters are changed often.the only reason I can think of for the difference in filter size is the different sizes in the wands...mine also has two different sizes some for the face and larger ones for the elbows etc. I hope this helps answer your question Steve.

3m P100 / HEPA filters for the Safe-Air or 7000 series respirators fit in there nicely. The Power Mask puts a gasket in the mask, and the 3M 7255 has a gasket on the filter. The result is a very good seal, though you'll have to crank it down a bit - the 3M filters are ever so slightly smaller than the Safe Air filters. I've switched to this combination for cutting fiber cement, and I can no longer taste the dust halfway through a cut. Airflow may be slightly reduced compared to a Safe Air OEM filter, but still adequate if you're not doing gymnastics. I don't care if the original ones suck; I'll simply use them to make mowing the grass-optional portions of the yard less miserable. 3m P100 / HEPA filters for the Safe-Air or 7000 series respirators fit in there nicely.

I think they work fine but you must ask others or M3 help to be sure for your particular contaminant. I think you can open it and change the particulate filter P95 but I didn´t it yet.

The less expensive one is just a paper filter. I've noticed that some of the more expensive ones contain carbon to filter out odors. Wasn't really a deal breaker for me. I just wanted to minimize construction dust.

the P100 cartridge is good for removing particulates only such as dust and dryed lacquer. It will only stop very small amounts of organic vapor like lacquer thinner fumes before being saturated. The 3M 6001 plus p95 filter will work for regular lacquer. Finishes which contain other coounds such as formaldehyde require a different filter media.

The 6001 is an organic filter for the 7500. However if your in a high dust environment you should attach a holder for an N95 particle filter so you don't clog up the organic filter.

Yes this respirator has a P100 filter which the CDC states "filters 99.&% if airborne particles" which includes mold. Here is the CDC (Center For Disease Control) website http://www.cdc.gov/niosh/npptl/topics/respirators/disp_part/RespSource3.html

They are both P100 filters "NIOSH Approved - At least 99.97% filtration efficiency" but you should check 3M's website for exact info. Link below you'll find docs and specs on each. http://solutions.3m.com/wps/portal/3M/en_US/3M-PPE-Safety-Solutions/Personal-Protective-Equipment/Products/Product-Catalog/~/Cartridges-Filters-for-3M-Half-and-Full-Facepiece-Respirators-6000-Series-7500-Series-7800S-Series-and-FF-400-Series?N=3294355784+3294529207+8690968+5549793&rt=rud
