3M 9542V KN95 (P2) Valved Particulate Respirator (Headband)

The 3M 9542V valved respirator is a genuine 3M flat-fold disposable mask that filters at least 95% of fine non-oil particles and adds a Cool Flow exhalation valve. The valve releases hot, humid air on each breath out, so the 9542V stays comfortable during long shifts in warm conditions, while its headband holds a secure fit.

Product overview

The 9542V is part of 3M’s 9500V particulate respirator range and meets KN95 (GB2626) and AS/NZS P2 protection levels. Because it has a one-way Cool Flow valve, exhaled heat and moisture escape quickly, which reduces heat build-up inside the mask. The over-the-head headband gives a stable fit for heavier or longer work.

Frequently asked questions

What does the 3M 9542V protect against?

It filters at least 95% of fine non-oil airborne particles such as dust and mist. It does not protect against gases or vapours.

What does the Cool Flow valve do?

The one-way valve opens as you breathe out, releasing hot, humid air. This reduces heat build-up and makes the mask more comfortable in warm conditions.

What is the difference between the 9542V and the 9541V?

The 9542V uses over-the-head headband straps for a more secure fit, while the 9541V uses ear loops for quick, comfortable wear. Both have the Cool Flow valve.

Is a valved mask suitable for sterile areas?

No. Valved respirators release unfiltered exhaled air, so they are not used where the wearer must protect a sterile field. Choose a non-valved model for those settings.
