Breathing in fumes from laser cutting and engraving can be just as dangerous as the laser beam itself. In this episode of the Ultimate Guide to Laser Processing, we cover how to keep your lungs safe.

We’ll break down the difference between disposable KN95 masks and reusable respirators, and we’ll dive into our recommended setups with the 3M half-face respirator paired with P100 (2097) filters and multi-gas/vapor (60926) cartridges. Learn when each option is appropriate, how filters work, and why proper protection matters for long-term health.

This is your complete guide to respiratory safety when working with fiber, CO₂, diode, and UV lasers.
