what is the pore size of the material. To be effective I need something with less than 6-7 microns

Mr. Boddy, I suggest going to Allersolf's website for this highly technical question. With this exception, I am very pleased with the Allersolf pillow cases and mattress cover that I purchased because 1) they are excellent in their capacity as pillow protectors and a mattress cover because they are high quality, and because their very tight 100% cotton weave is very smooth, absorbent, cool, and very comfortable, and 2) I don't know if they help with my allergies but they definitely don't make my allergies worse.

I'm sorry but I don't know the pore size. It's not listed in the description nor on the case. I don't have the pkg it came in anymore either. Sorry I couldn't help more but I have been very happy with these.

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.

Well get your self a 5 gal bucket and put the 25 micron bag in then in it put the next size micron bag and so on tell the 220 micron bag which is the bag your material goes in the add ice cold water to cover material then add ice. Mix this non stop for 20-30 min. Should be white and frothy during mixing. Let settle for 15-20 mins the. Start draining the bags. Try not to squeeze the bags let them drip out. Well I hope this helps you.

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)

Sorry, I don't have a tool to measure in mils. It's less thick than a ziplock bag. Pretty close to the thickness of a standard sheet of copy/printer paper. I use them for a lot of applications, and the only time I have had them rip or tear is when I am scrubbing something clean and I use my finger tip/nail; sometimes my nail + the pressure slices through the glove. Also, occassionally I'll get a defective glove (maybe 1 in 1000) that snaps/breaks when putting it on. I know it's not the answer you were looking for, but I hope it helps.

I believe it is 5 microns.It's the mask use in surgeries and the one use during the Avian Flu.As a heart transplant patient, it is the one the surgical team uses during surgery.Be aware that when wearing it, you do get hot and may perspire.

j. ; hi do not have one of the clear glass files in front of me, but they are pretty small. I am thinking only 1 mL. if you would like me to, in about six days I will be able to get back with you with an extract size.

i did not provide the picture but i bought the 200 ml size. more product,better price. can be used on more than just wood; plastics,metals. dries very quickly and eliminates finger prints. buy the big size,you only need a little but will last a lot longer.

It is less than a millimeter. It says it provides a protection of about 6-8F.It worked well to start my veggies early this Spring.

Around 1.75 inches, give or take a few thousandths. I don't have a micrometer to be exact.

I don't know how small a micron is however I have it in my man cave and it does real well, you should also buy the carbon filter that goes on the outside of this filter. the carbon filters are usually 3 inches longer with 3 or 4 Velcro strips to hold it in place. the carbon filters do a great job and if you want better try putting 2 carbon filters on, and then you just wash the carbon filter. hope this helps.

In regards to the microns for the material to sift thru? Each one ranges from i belive 23-223 i love the bags when i have a lot of trim etc. But i put a 3 ft hash plant thru them and stiill only got around 5 gs of bubble. More expensive bags get you more material in the long run but these work fine for personal use.

I would say that the .005 would be the minimum thickness if it were secured well on all sides, it still might have a wavy look. The .020 thickness would be the best choice for that application in my opinion.

ok :) in mm it will go as 2.5mm, 5mm and 8mm :) that's the mesh sizes :) hope it would be of some help :)

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

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 bought these masks for health reasons (illness, contagious diseases, etc). But I believe that 2.5 microns are smaller than 3 microns. It's possible that the 2.5 microns could seep though the mask.
