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.

To keep dust and mold out of my system I used the pink circle filters (3M Tekk P100 Particulate Filter with Nuisance Level Organic Vapor Release) and it worked wonderfully--much better fitting and much better working than those disposable masks. If you have allergies or asthma or got really irritated lungs/nose/throat the last time, I would recommend this for the next time.Others have mentioned more detailed specs on the 3M website. (Your second question, I don't have a response for.)

I'm sorry but I don't know. If you have used in the past, you might continue. I have never had dust mite covers so have no basis for comparison.

These pillow fabrics are treated to prevent dust mites, so you shouldn't need one. That's why I like them, you don't need the extra dust mite covers like on standard pillows. That saves money, time washing extra pieces, and room in the linen closet.

Possibly dust but it depend on what type of bugs you are talking about. I bought them for the attach lids but for the quality of the boxes and the price they ask, I would not buy them again.

I don't know about microns, but the filter helps with allergens a lot. I live in the deep South where the pollen is very bad right now. Allergy testing revealed that I am allergic to everything tested except two items. It is wonderful to experience relief.

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.

Not sure. I sent these back because they were micros and not standard. Sorry.

Thank you for the reply, but I was referring more to the mesh itself if it is fine enough to keep very tiny bugs out.

Have absolutely no idea. Never tried these on any fabric either sticky side or Velcro side. Just used it to keep equipment from sliding on desktops, which it did a really good job. The sticky part was removed with some difficulty so does not appear to be permanent. It could set in after many months.

With a mean flow pore size diameter of 4.91 microns, this fabric is one of the most effective barriers against pet dander, dust mites, bed bugs and other harmful allergens.

There is a sonicrafter accessory called a "Dust Extraction Adapter", that hooks up to a shop vac. My guess the adapter screws into the holes. The adapter didn't have very good reviews, so I passed on buying one.

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

As a few others mentioned, the openings in the mesh are each about 1 mm square. Hope that helps!

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.

I do not know--it is too fine to count--however I can tell you that nothing, nothing gets through! Material is also strong--used for months by my two boys, one of whom has an insect allergy--very, very nice. It is less a "netting" than a super fine, heavy duty veil. No mosquitos, blackflies, gnats/mingies, fleas...nothing gets through....We like these very much. Even the zipper end is super flush.
