how effective are these filters for powder fine dust,& can they be opened to replace filters inside.I'm looking for the best micron size particle filter for a 3m 6000 full face respirator

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.

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.

They are intended more for vapor than dust. No they cannot be opened to replace filters inside.

from what Ive seen from 3ms website, it looks like particulate filters are used for biological with the minimum being something like the 3M 2091 P100 Particulate Filter. Some of the cartridge filters appear to also have a particulate ability and p100 rating, but Im still figuring this all out. In regards to ebola and respiratory protection follow the link below, or if you dont like clicking on links, then just google "Personal Protective Equipment (PPE) for Ebola virus disease (EVD)" You will see the link to 3m's pdf file http://multimedia.3m.com/mws/mediawebserver?66666UgxGCuNyVs658T_OxM6EVtQEcuZgVs6EVs6E666666--

Molly, The IQAIR HealthPRO that I purchased for approximately $50.00 less back in mid-2011 came with a premax filter and a HEPA filter. It did not have the V5 Cell. I would also recommend purchasing a coarse dust filter (a box of 5 runs about $50.00). You place this filter on the underneath side of the HealthPro. It helps to filter out the coarse heavier dust. I believe that these filters assist in making the premax filter last a few months longer. I normally discard the coarse dust filter after approximately 3 months. I have had my IQAIR HealthPro unit running continually since mid-2011 in my office here on Bagram Airfield, Afghanistan. The air here is saturated with dust. This unit does a tremendous job keeping my office nearly dust free. Kudos to IQAIR's HealthPro for an excellent product!

No. These are strictly particulate (i.e., 'dust') filters and provide no protection from organic or inorganic vapors. Google "Selection Guide for 3M Reusable Respirators" for recommendations.

Yes they are HEPA filters. However, I've had allergic reactions using the 3M mask with these filters, and I don't think I would if the mask were truly removing 99.97% of the allergen. Some allergens leak through, somehow. These filters are the best I know of to filter out allergens, but I've had many allergic reactions to animal dander right through the filter. And to some kinds of mold. Either the filter itself isn't very good at filtering out some allergens, or other parts of the mask leak somewhat.

Unfortunately I was unable to find the Honeywell #7 filters. The The Filtrete Dust and Pollen Reduction Filter attracts and captures large allergens like dust particles from the air passing through the filter. Carries a 600 Microparticle Performance Rating (MPR) and lasts up to 3 months.

I am wearing the mask to clean out a hoarder's residence - dust, mold, mildew and ofther fine airborne ickiness. I believe the mask is good for .01 microns. The manufacturer's website has the details. I have found the masks very effective. Initially it felt claustrophobic to wear, but I got used to it. I definitely notice a huge difference if I am in the environment without the mask. Track your wearing time - the filters are rated for about 40 hours use. I have found this to be fairly accurate.

I use the ceramic filters. At the time they said the red cross and unicef used them. That was good enough for me. I also read a review that said the stem on the black filter broke easy. I don't know if that was true, but I didn't have the money to try it to find out. I prefer tried and true. I LOVE my Berkey with the ceramic filters and they are very easy to clean. One of the best investments I've made for me and my family.

Hi Gail,Thank you for your question. An interesting fact about HEPA filters are that they were initially designed to prevent the spread of airborne radiation during World War II. That being said, unfortunately, we do not know to what degree the filters will trap the radiation particles as environment and degree of particulates in the air are usually unknown without prior testing.We hope that this shed some light for you, and if you have any other questions, please feel free to contact us again.Kind Regards,Rabbit Air Customer Care Team

I think it can!! DE is the way to go- as it filters out the smallest particles of any filter. I would do a Google search first- there is I'm sure a chart of what size pool each filter can handle.

No. These filter only particles such as fine dust. They are not effective against vapors. There are other cartridges for that purpose.

A company representative informed me that it filters 100% of that particles. Their website says "99%" of particles. Another company representative said that it was "under 1 micron."

Yes they do a pretty good job overall of keeping particulates out. I Use them for cement dust. Nothing is 100% when it's that fine.

This is made for particulate matter so it won't help much. A half face respirator or whole face with disposable filters meant for vapors would be much better. A cheaper niosh mask N 100 or N 95 will help less and must be changed often but something is better than nothing. The valve in the mask you asked about lets odor and some vapors in. The best beside the respirator as for smelling it are the blue N95 in the least expensive area. I'm surprised her employer does not provide this.

Ther larger number of Mesh, is the better filter (filters out smaller particles). here is a link http://www.fs.fed.us/r1/fire/nrcg/2011%20Inspection%20Forms/11_Micron%20and%20Mesh.pdf

John I would also like to know what it is. However, most of these types of filters I have seen generally have a rating of 3. It's about equivalent to the old fiber glass filters, low dust pickup but high flow. I have a 10x6x1 box (in addition to the others) in my house and it is IMPOSSIBLE to find an actual filter for it. Even the builder put in one of these types of filters. I've been here for 10 years now and haven't had any issues with my system or this type of filter for just this one.

It will help, but you will have to run it at a higher speed and replace prefilters more often. Best bet is to purchase a larger machine for the room. Technically it will filter the particulate matter from cigarettes, since the device was developed as a Class II medical device, but this is the retail model.
