Is there an available size chart online? If not, how is a buyer to figure out which size to buy?

3M Rugged comfort half facepiece respirator: The size is adjustable and can fit a large variety of head sizes. It works for both me and my 9 yr old daughter

How does the 6500 compare to the higher priced 7500? i am an emt concerned with wight & comfort, and patients being able to hear me talk.

Very similar. The main difference is the 7500 series all silicone. Voice may be muffled, just have to speak up. Call the 3M Techline at 800-243-4630 for any assistance. Thank you.

Does this work as an N95?

This mask has different cartridges some for toxic gases and I think this is more than enough and surpasses what the n95 can do it is not disposable the mask is rubber with no requirement for fitting has check valves for positive breathing and needs to be cleaned .
