What can I say? Through my work in the Asbestos industry I know about masks.
Anyway you might want to get yourself checked, I think you have caught a dose of Dr Axon’s “Sneering attitude” ???
Why bother with all the effort of getting properly fitted masks. Sticking your head in a ceiling void full of asbestos wearing a home made face covering will be fine.
