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.
