Particulate size is usually listed as a spec - do not see it here. They are typically rated at 5 or 10 microns. What are these?

I have not used mine yet, but the silt filter is 5 micron. the other 2 are charcoal.

It is rated for N95 which supposedly filters out 95% of particles. They don't state pm, Not for toxic or harmful substances such as lead, asbestos, and oil containing vapors, hope this helps.

A micrometer, commonly known as micron is one millionth of a meter, one thousandth of a millimeter or one thousand nanometers. A strand ofhuman hair is about 100 microns wide and a red blood cell is approx. 8 microns in diameter. A Micron is .000039 inch or .001 mm. This filter is rated at .003 Microns! Get this filter!!

no definitive #'s bottle just states "nano meter particle size and a a graph showing particle size is in the smallest angstrom size. Maybe ask manufacturer

Culligan (not Amazon) lists this as a class 1 particulate filter - meaning between .5 and 1 micron filtration.

The smallest is 2.2 mm, the largest is 11.2 mm (approximately). I use them for light duty applications, and so far they have been fine.

With microns it goes the bigger the number the bigger the (hole). Mesh is the opposite, the smaller the number the bigger the (hole). So a 100 micron would be smaller (finer) than a 400 micron.

According to the EPA (http://www.epa.gov/mold/whattowear.html) N95 is recommended. N95 is required to filter down to 0.3 microns. According to all the googling I did, mold spores are larger than 1 micron. Please google and/or check with a mold expert on the micron size of your particular mold.

I'm not exactly sure but I read somewhere that the process most mass produced companies use is a high voltage AC current and produces larger than desirable particles. Actually, the smaller the better because it is more easily absorbed and bioavailable. My home generator uses a small DC voltage with an air bubble hose which supposedly generates very small particles so only about 12-15 ppm are needed for consumption due to small particle size. So basically if u r buying a store bought colloidal silver a high ppm is generally better as they are larger particles and less are absorbed and also they are generally half of the ppm that they claim. I'm no expert but this is what I have gathered and believe to be true.

This filter is a 9-7/8-inch by 2-1/2-inch 1 micron sediment cartridge. It fits most industry standard 10-Inch filter housings, manufactured from pure polypropylene microfiber for reduction of sediment. Regards, WaterFiltersOnline.

I just put the micrometer on some of the cleanest castings that I had sitting around. I was quite surprised to find that they are not round. The smallest dimension on most of them is .356 and the largest varies between .357 and .358. I assume that this out of round condition goes away they are put through a sizing die. All the measurements were made at the base.

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--

the 1100 pro does >0.5 microns and >2.5 (both readings) one is on the left side and one on the right side. http://dylosproducts.com/dcproforairp.html or http://dylosproducts.com/ornodcproair.htmlDC1100 Pro has all the features of the standard DC1100 but with increased lower sensitivity - detecting particles down to 0.5 micron. The large particle size range is calibrated to 2.5 microns and above. so the small number shows you .5 to 2.5 and the large is 2.5 and up.

It is very fine, not sure of the micron. A great product, we use it regularly

I'm not sure,but you can make an research on Google,I'm using this respirator for asbestos removal.If silica particulars(dust)are smaller then 0.03mm that is not ok but if particular are bigger than 0.03mm,than is ok.0

Hello there. To answer your question, no the mean particle size is NOT less than 100 nm. I searched for a few days to find a product that had a particle size of LARGER than 100nm. If you scroll down, under "product description" it states: "Produced from naturally occurring zinc ore, super purity (free from other metals). Cosmetic grade particle size 200-1000 nanometer (nm) or 0. 2-1 micrometer)."

As I noted in my review, all of the filters that I rec'd are marked 228 micron. It is my understanding that the "assorted" means that you could receive anything in the 90-190 micron range (even tho I rec'd 228 micron!); "assorted" does not apparently mean that you will receive an assortment of sizes.
