How many microns does it filter at?
870137
What micron size is the filter? Nov 6, 2013 It uses multiple newer technologies to kill and filter, not just filter like other straws do. When a competitors straw relies on just filtering the size needs to be incredibly small to make sure it blocks all the things that could kill you if ingested. The problem with that is that they are also difficult to suck water through and end up clogging up easily. We instead use both filtering technology and also technology to kill the pathogens to make sure to protect you. * 6 Stages of Filtering Including Ionic Absorption of particles to 2 Microns * Removes Chlorine, Iodine, Heavy Metals, VOC, Industrial Pollutants, Agricultural Runoff, Chemicals & Trace Pharmaceuticals * EPA Approved Iodinated Resin (Proprietary Technology) Kills Bacteria & Virus (Giardia & Cryptosporidium) There are additional test results in the listing to show how much of each of the above are killed or removed.

No, filtration size is 0.02 micrometers. Flouride is at the atomic level, less than the filtration size of the ceramic filter.

It stirs the dirt up and sucks it through a fabric filter. I find that some particulates get through. The filters come in various capabilities so get the finest available, 2 microns.

In talking with the manufacturer, I learned that the dc1100 pro is able to measure small particles down to .5 microns. The dc11 measures down to 1 micron. I learned that for my purposes in terms of monitoring an air purifier and air quality in general, it isn't necessary to get down to .5 microns. The Pro would be suitable for checking air quality for clean room applications as in woodworking areas etc.

I'd go with a much stronger filter. 1.8 maybe. Don't stack you'll just be begging for light scatter shooting in to a light source like that.

The lens should indicate what filter diameter it uses. Look for a symbol like an O with a slash through it, which will be followed by a number. That number is the filter size in mm.

I have been researching small filter as I work with various manufacturers of larger reverse osmosis systems. Frankly, this product scares me; you need at least 0.1 micron to filter out bacteria. That still leaves viruses, some chemicals, silica, and various dissolved solids. The only way to deal with some of these other contaminants is to use reverse osmosis.

I have no idea. I guess it would depend on the composition of the filter that you have. This is good stuff.

I love the filter.. have used it is Mongolia in Ulaan Baatar which has terrible air quality.. Also, Jerusalem, Israel and calgary, Ab. It works . I could not say about the microns.

I have a Ph.D. in Microbiology. If the filter throughput is a true 15 microns, it's not as safe as I would recommend. In the lab, we routinely use 0.22 micron or smaller pore size to make sure we remove bacteria prior to work with samples. This 15 micro filter might be fine for protozoa or very, very large bacteria, but I would be cautious. I take all of the specs of any item like this with a grain of salt so to speak. There isn't a filter for this type of use I've seen on the market that can prevent viral contamination, so boil after filtering if the source is suspected of high levels of multiple biologicals. This filter and decon-tabs might work in a pinch... Best of luck out there... I have a Ph.D. in Microbiology. If the filter throughput is a true 15 microns, it's not as safe as I would recommend.

50 Micron pre-filter and 5 micron post-filter. The filter is more densely wrapped toward the core.

No it is not, it physically removes particles, protozoa, and bacteria down to 0.3 microns in size, including giardia, salmonella, cryptosporidia and others. I love this filter.

Filtrete filter has electostatically-charged fibers that can capture particles as small as 0.1 micron.

I cannot answer about the micron size! this mask with the P100 Toxic dust filters Meets OSHA and NIOSH P100 requirements for scraping lead paint or working near Asbestos , or working around Toxic Mold! Respiratory protection against particulates under the 42 CFR 84 P100 classification (99.97% efficient against all particulate aerosols including oil-based aerosols).

The purpose is to remove solids from the water. I don't know the exact size in microns but small.

This particular technology is proprietary and the manufacturer doesn't give a number. In marine applications, a 10μ filter is usual for fuel-water separation.
