No, no, no, no, no, NO!
I had a call this week from a company offering a face fit test service for paper dust masks – to say I was appalled is a complete understatement! The performance of loose fitting face-pieces (such as paper dust masks) relies on sufficient airflow through the face-piece and is less dependent on a tight fit to the wearers.
All you need to do with these type of dust masks is to ensure that any supplied are the correct size to fit the wearer.
