Is it "True HEPA" (.3 microns)?

I find no dust after it does its job. It says HEPA so I expect it to be HEPA.

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.

The higher the Micron rating (50) the less likely you are to lose any pressure.The lower the rating (5), you may see a slight drop in pressure.But keep in mind,the lower the rating,the MORE crap is being filtered out. And you have to change filters on a regular basis,dont wait until the filter is is so covered in sludge that you cant tell that it WAS at one time,white.

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."

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

Pure HEPA filters are the best for the money. This particular model is very good I have 2 I recommend it.

Pierce- check out the Wynn Environmental website. They make some great aftermarket filters. I believe the one I picked up a year ago (I'm not home right now) is the 35A canister, which requires a slight fit adjustment to my (your) Delta dust collector, but it works great. I think it's 0.5 micron. Also remember that there's a trade-off between filtering capability and airflow, so the "low micron" filters require more surface area on the filter to ensure adequate airflow.Chris

Yes, it is. It is very well designed and the use of HEPA in the title would suggest that they will be libel of false advertising if it is not the case. Go to the manufacturers web-site: http://www.pro-team.com/vacuums/?style=1&id=106576

Not sure the microns. I bought this over a year ago very happy with it. It has no problem pulling the vacuum down to the lowest reading on the set of gauges that I have.

I'm pretty sure the pre-filter and hepa filter are together. The pre-filter is at the front and the hepa is at the back.

Your mean HEPA. You do have to be careful about how the cover is latched down. If it's not properly in place, it will pop up. The cover should be on about the same level as the case around it. Hope that this helps!

the manual states that it pulls down to 30 microns, but that would be dependant of some factors such as your local barometric pressure and what your using it for

not sure of the micron measure however it is very fine great for packing capsules

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. Berkey doesn't publish micron ratings as they're a little misleading.

Not sure if this is the answer you wanted but specifications show: Dust Removal Rate at..... 1 micron 99.97% - 0.3 micron 80%

There is not micron requirement, but if your water is dirty or needs filtered, you should use a filter before. Standard for whole house filtration on sediment would be 5 micron which is pretty small. Going to a 1 micron may restrict your flow and pressure too much. Contact us for more information, AFW Filters 785-735-9769

I cannot say it is a "true" HEPA filter but my son has terrible "environmental" allergy and the 726 helped a lot. We used it in his bedroom and moved it to his dorm room when he started college. The filter helped him while he is in school and I was very surprised to see how much dust collected on the carbon filters (C) and the "B" filters. We brought two new set for him to bring to school this year.
