Where do you buy the replacements. How often do you replace yours. Thanks, Frank

Granger, Uline, and McMaster Carr should all have them too.
The instructions usually give a specified usage time for each filter. Usually on a mask you can tell by the amount you have to work to breathe if it's time or not, but on a PAPR style system, that might be a little difficult.
I'd recommend having a spare on hand if you can, and if it won't react to atmosphere in general (some vapor filters react to ambient vapors over time by just being exposed to air), swap them out real quick and see if you notice a difference in air flow. Pitch the bad one, or seal up the new one in a ziplock to preserve it longer. A dust filter shouldn't have any reaction, so a ziplock should be fine.
