Upgrade your protection from disposable respirators. These respirators have a rubber mask that creates a tight seal to protect against a variety of contaminants in the air. When you inhale, air is pulled through a cartridge or filter that removes contaminants. Replace cartridges and filters when breathing becomes difficult.

To achieve the listed filter rating, you’ll need a respirator that creates a tight seal with your face—any gaps may let in contaminants. Choose a respirator that matches the style you have been fitted for.

Silicone rubber respirators are a good choice for comfort during periods of extended wear. Respirators with a quick-release latch let you take off your mask with one hand. Flip the latch up to break the mask’s seal, so you can lower it. Push the latch down to tightly seal again.
