How to recognise a good breathing mask

How do you recognize a good breathing mask?

Good medical respiratory masks cannot be distinguished from bad respiratory masks without extensive testing.

Indications as to whether it is a cheap make:

• The respirator is loosely fitted.
• The breathing mask is easy to tear
• The breathing mask does not cover the nose, mouth and chin
• The breathing mask slips easily
• The seller cannot provide any information about the standard and the standard is not visible on the package
• The manufacturer cannot provide information on the results of the testing
