How many microns are the fabric holes that allow/prevent dust mite particles? (Please don't respond unless you actually know)

I have no answer for you, sorry about that, but that might be a question for the company that made this cover.

I`m not sure what you are asking me, but this protection rejects dust very good. Better then without it.

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

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.

Definitely made with fabric and work great in capturing dust, pollen, fine dog hair and mites. When you remove them you also do not experience dust in your face. Worth the price

I've emailed the seller of this product, Hospitology, because I have a dust mite allergy and was wondering the same thing. They responded extremely quick and said that this mattress encasement also protects against dust mites.

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.

They were an exact fit replacement for my original Hayward filters. I don't know the micron size but they clean as well if not better than the originals. I recommend them..

Not really sure...I use Merv 13 4" AC Filters and they do a very good job at that...I did not notice any difference in regards to dust/particulates....

There is no such term applicable for this product. It is not a cotton but engineered kind of fabric. So micron size would be 0.

I don't have a micrometer to give exact but the grains are course and large. The mixture does create a fine dust so be prepared.

The documentation that came with the filter states "minimum particle size filtered is 450 microns". That would make it between 35-40 mesh according to the conversion chart I am looking at.

I don't know about micron ratings. If my mask is rated 3 microns, then I suspect it would not protect against 2.5 micron particles.

There should be a standard cheap filter for small particulate/dust. They should all be standard and need no adapter.

I will not answer that question directly, however I can point you to the 3M informational page which is here. http://www.3m.com/product/information/P100-Particulate-Filter-Respirator.html I hope this helps. Good luck!

I think the ventilation holes are there to allow the heat to flow out. Since its underneath, I don't see how dust will build up too often.

There are 2 filters. The outer filter is pleated measuring 9 1/2 X 16 1/2 X 2 inches. The inner filter is is "sock" type and is stated to trap dust down to 1 micron. The manual says both filters can be cleaned several times before they need replacing. I would discourage using a furnace type filter because they are not designed to filter dust down to the low particle size required to filter properly. Using such would most likely saturate the inner filter very quickly and could cause motor overload.
