Respiratory Protection FAQ

Last Update 2 years ago

What is the expected working life of a filter? How long will a disposable mask last? I have been told that some disposable dust masks are reusable, is that true? How do I clean my half mask? Is there a respirator that can accommodate all facial features and face sizes?

I have seen different filters with different colour bands on them, what does that mean?

Each colour signifies a different gas/vapour or dust that the filter is designed to filter out. 


The table below taken from the UK Health and Safety Executives publication HSG53 shows the different colours and what they mean.
