How fine a particle do these filters filter in microns?

Ultra Fine Filters supplied by CPAP Filters and Supplies.com capture 99.99% of bacteria and viruses according to Nelson Lab reports. Most viruses range in size from 5 to 300 nanometers (nmSource: Boundless. "Viral Size." Boundless Microbiology. Boundless, 03 Jul. 2014. Retrieved 16 Mar. 2015

you would have to contact respironics lab in order to get that tech. info, I have been using for 3 years and no problems yet!!! and I am still breathing!

I have been using these filters for some time now and never any issues, these filters seem to do a very good job at catching fine dust and dog dander. I do change mine more often than the manufacturer recommendation, I do so every 2-3 weeks just to make sure that my system is not working harder to keep up.

These are meant to filter extremely small solid particles. Key word: "solid". Pollens, pet dander, micro-dust, etc.. For most hazardous fine vapors (i.e. gases) and potentially-hazardous liquid materials that are sometimes used/applied as "mists" (lacquer paints and insecticides are two of many examples), you would want to use filters made of a different (finer, tighter?) mesh material.

Depends on the lens attached to the camera. If you are looking at the end you would attach the filter to, you should see a zero with a slash through it followed or preceded by the size in millimeters.

They should eventually go away. Your h300 is a .25 micronfilter. The elf-5m-kdf-p is 5 micron, it will allow much larger particles through. If they are white it may be calcium. Harmless go nack to the h300 much better filter

No they are particulate filters. Good to 1micron. Would likely stop most of paint pigment but not the vapour. You would need organic vapour cartridge for this mask as well.

None, you must choose the type of filters based on your specific ned, such as dust, organic vapors, etc.

Berkey doesn't publish micron ratings as they're a little misleading. From their website, if a filter traps of 0.2 micron particles then it's acceptable - even if the other 10% lets in 1.0 micron particles - to call it a 0.2 micron filter. But if you read the test results on their website, their filters are capable of filtering 99.999% of viruses and 99.9999% of bacteria. That's better than almost any filter out there. In fact, you test the filter by adding a teaspoon of red food coloring to a gallon of water and running it through the filter. I can vouch for the fact that in mine, the water comes out crystal clear.

I don't know if you can use that filter however I would say it is very important to use the SuperSterasyl Filters to achieve the 5 micron's (99.99999% pure)

5 micron is the largest size, you can use a 1 micron if you wish. If you use anything larger then 5 micron the "bugs" can hide behind the particles! I use a 5 micron filter.

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.

Yes, though I think the .5 to 2.5 micron range is only for the pro version. For mine, small particles are 1-5 microns, large is > 5.

The cloth bag at the top is the filter and the bottom one is the collector bag. I don't know the micron size but it lets very little dust out of the system. I also have an air filter that turn over air in shop 8 times per hour. I do not think there are any filter options on the shop fox or on any other brand.

upon research... it would appear that the Carbon filter claims a filtering criteria of down to .1 micron... while this filter claims only a .3 micron thresh hold... that means that all the dust and dirt particles between .11 micron and .29 micron will pass right through this filter.. but be caught by the other.. in addition. the carbon filter does indeed offer an effort towards odor reducing overall in the home.. the house smells fresher faster.. and stays that way... that's why we went for the Carbon clean..

Fairly tiny. The bottom catch filter is a tight mesh screen. So tiny enough for floaters you can see but not tiny like a fabric screen you see on robots.

The Family filters to 0.02 microns, which is an extraordinarily fine filtration level. Since it removes viruses in addition to bacteria and protozoa, they call it a purifier. The LifeStraw filters to 0.2 microns, which removes bacteria and protozoa. Viruses in reality are quite rare in our water.
