How long is a piece of string! the length of time depends on various factors, how much dust, fumes are generated in the atmosphere, how long you are exposed to the dust & Fumes etc. if it is heavy use then you would need to replace these more regular. if your employer is asking you to wear this then you MUST be RPE tested its a legal requirement., no point in giving you a mask if it does not fit. Also training on how to wear, fit check etc. is highly beneficial to the user. once you fit your mask carry out your own pre-user test to ensure the filters are working. Remember PPE is the last line of defence, not the first choice.
