Question 1

What micron will this fillter down too?

Accepted Answer

Dear Troy, 
I'm afraid the manual does not specify the micron sizes (at all).  I was hoping it would filter down to around 0.5 microns (50 nm nanometers) however, even the N95 masks only filter out 0.3 microns (which is 30 nm).  Current literature indicates that the sizes of various SARS/COV2 particles are around 60-140 nm (0.06-0.14 microns - much smaller than the capability of the masks we've seen).  Anyway, I found no mention in the literature..  While the body seems sturdy enough, I haven't yet tried it out in the field.  One of the primary reasons was to get some eye protection with a respirator.  I saw a short video here on Amazon stating that the 3M FX FF respirator (again, a full face assembly) was the best.  Not sure how much that costs, but 3M is always reliable.  The one I got was of Chinese manufacture.  There was nothing wrong with any of the valves or respirator parts so I'm confident it would work (I did a great deal of research and chose this one because of cost, seemingly solid construction, etc.  The latex seals fit around the face rather well; I wear glasses, so that's going to be a bit of an issue I have to deal with in due time.  If you're thinking of purchasing it for construction, asbestos, chemical, pollen, sanding, painting, mold abatement, etc., then this is very good.  For the Covid-19 virus protection, I think (though not tested outside) it would work well... the purpose of which is to offer breathing/filtering while affording one the chance against touching the face, especially the eyes (which has proven to be an area where you can be infected.
One alternative I am considering NOW is getting two pieces; one would be a goggle assembly like the DeWalt Brand DPG82-11/DPG82011 CTR Goggle (for $15.90) and a lower piece respirator (lower portion only)... considering the 'heavy, apocalyptic nature of the full face mask and the inconvenience of sliding both the eye and respirator portions every  time, I think it might be a bit more convenient (and safer, perhaps) to keep the two parts separate.  I know my text did not answer your questions directly, but I've done enough research to share my thoughts on the mask.  I may end up returning this, either for a gas mask full face assembly with a biological component (as in 'ARMY' issue USAMRID type mask - which is really, really expensive) or keep to the two part assembly mechanism.  If you'd like to share your thoughts, you can contact me at: Second Lawrence at Yahoo Com.  Thank you

Question 2

Is this n95 or greater and does it provide 0.3pm protection?  if not, is there a filter available which does?

Accepted Answer

this is kn 95 filter, but this mask compatiable with 3M filters

Question 3

can you wear glasses with this?

Accepted Answer

NO, could not wear glasses for this mask

Question 4

Can this be used safely on a covid unit?

Accepted Answer

I'd say yes because it protects you from chemicals. But that's breathing in the infection, you need a face sock to protect your exposed skin area as well.
