3M™ 9542 KN95 Particulate Respirator with Activated Carbon

The 3M™ 9542 is a flat-fold KN95 disposable respirator with an added activated-carbon layer. It filters fine particulates while the carbon layer helps reduce nuisance organic-vapour odours, making it ideal for tasks with both dust and mild solvent smells.

Product overview

The 9542 filters at least 95% of non-oil airborne particulates to the KN95 standard. Its activated-carbon inner layer reduces nuisance organic-vapour odours below the exposure limit, while the foldable design and adjustable nose clip support a comfortable, secure fit.

Frequently asked questions

What does the activated carbon layer do?
It reduces nuisance organic-vapour odours present below the occupational exposure limit; it is not a substitute for a gas cartridge where limits are exceeded.

How does the 9542 differ from the 9542V?
The 9542V adds an exhalation valve for extra breathing comfort; the 9542 is the unvalved carbon version.

Is it reusable?
No. It is a disposable respirator for single-shift use and should be discarded when soiled, damaged or breathing becomes difficult.
