Respirators

Respirators are a type of face mask designed to reduce exposure to harmful airborne bacteria or chemicals. When worn properly, a respirator mask protects the wearer from inhaling dangerous substances that could cause illness or difficulty breathing. Staples sells a variety of personal protective equipment, including two kinds of respiratory masks: particulate respirators and chemical cartridge/gas mask respirators. Particulate respirators are the most common and filter out airborne particles. A gas mask respirator filters out chemicals and gases. With either type, users must ensure there is a snug fit between the mask and their skin for maximum filtration and safety benefits.

The type of respirator mask that will best serve the user depends on what they will be exposed to. Different types of masks are better suited to filter certain substances varying from metal pouring, pharmaceuticals, bacterial particles, mold, smoke, and more. Learn more about particulate respirators and chemical cartridge/gas mask respirators and their recommended uses below.

Particulate Respirators

Particulate respirators are the most affordable type of respiratory mask, though they only filter airborne particles and are intended for low hazard levels. This type includes N95 masks and other face masks designed with a filtering facepiece that protects the wearer from infectious agents. Particulate respirators are secured to the face using two straps that are meant to go around the back of the wearer’s head.

Chemical Cartridge/Gas Mask Respirator

Chemical cartridge/gas mask respirators are also known as air-purifying respirators, as they filter chemical gases and some particulates. These masks are designed to be secured around the back of the head with the filtration piece worn snugly over the nose and mouth. This kind of mask works well for those who are working with paint, pesticides, agricultural materials, construction materials, automotive materials, and certain organic particles. These face mask respirators are only effective, however, if used with the right cartridge or filter for the biological or chemical substance, so be sure to check product descriptions.

A respirator’s efficiency depends on a proper fit. A respirator mask should be worn snugly against the face with straps secured either behind the ears or connected at the back of the head, depending on the design. To test whether your mask is snug enough, put both hands over the filter or filter mouth holes. If you cannot inhale with the filter covered, your mask fit is appropriate. If you do get air, your mask is either not snug enough or has a leak. In this case, make adjustments or choose another mask. If you can taste, smell, or feel the substance you are avoiding exposure to, or if you feel drowsy, dizzy, confused, or nauseous, your mask is not properly protecting you. Avoid exposure and replace your respirator mask.
