Question 1

I know this mask comes in 3. How do I know what size I need? What are the measurements? (please don't say Small, Medium, and Large--that means nothing)

Accepted Answer

I used the website below that was extremely informative for sizes. The mask is the same size and has adjustable straps for all head sizes. The sizing differences of small, medium & large have to do with the inside rubber seal the goes around your face (cheeks, chin, forehead). There is a 3M mask fit test kit but it costs $240 from 3M. 80% of people fit the Medium size. 5% small and 15% large. The website below offers a visual comparison of how the gaskets differ in size.

Question 2

Does this mask protect you from airborne viruses such as Ebola?

Accepted Answer

from what Ive seen from 3ms website, it looks like particulate filters are used for biological with the minimum being something like the 3M 2091 P100 Particulate Filter. Some of the cartridge filters appear to also have a particulate ability and p100 rating, but Im still figuring this all out.In regards to ebola and respiratory protection follow the link below, or if you dont like clicking on links, then just google "Personal Protective Equipment (PPE) for Ebola virus disease (EVD)" You will see the link to 3m's pdf filehttp://multimedia.3m.com/mws/mediawebserver?66666UgxGCuNyVs658T_OxM6EVtQEcuZgVs6EVs6E666666--

Question 3

What full face respirator works best with glasses?

Accepted Answer

Some people say that this one works with glasses. Have never tried it. Thought about it but feel that to make sure nothing comes in there should not be any openings. The glass frame might allow for small particles to come in.   Might be worth a try though.   The 3M one works really well otherwise and is a good buy.  I only used contacts and that worked well.

Question 4

would this work well for saw dust as in wood turning

Accepted Answer

Absolutely but it's probably overkill.   I do all my turning outside so I just wear a plastic shield but this would work.
