Air-Purifying

Air purifying respirators use cartridges or canisters constructed of carbon or paper-based filters to remove contaminants or particles from non-IDLH (Immediately Dangerous to Life and Health) environments.

Air purifying respirators that rely on the user’s inhalation to draw the ambient air over the filters are called negative pressure air purifying respirators. Those that utilize blower to pull the ambient air through the filters and then push it to the user are called positive pressure air purifying respirators.



Full Face Respirators
Full facepiece, negative pressure respirators utilise either one or two filters/cannisters to filter contaminants or particles from the ambient air in non-IDLH environments such as spray painting, pesticide control, or military applications, while providing added eye protection from irritating fumes, particles, or debris.
Half Face Respirators
A half facepiece respirator is a negative pressure respirator that provides a tight seal around the nose and mouth and utilises one or two filters to remove airborne contaminants.
Filters/Cannisters
Air purifying respirators use filters/canisters to purify the ambient air that contains gases, fumes or particulates that are not (IDLH*), but are irritating or can cause damage over long-term exposures. These use various filter media, including carbon, activated carbon or pleated paper filters to removed contaminants or particulates.
Powered Air Purifying Respirators (PAPR)
A PAPR uses a blower or fan to pull contaminated air in over a filter/cannister to purify it and provide clean, breathable air to the user. This positive pressure respirator provides a continuous flow of cool air to the user and can be used with various facepieces, helmets and protective hoods in numerous applications such as welding or decontamination.
Disposable Respirators
A disposable respirators is a negative pressure respirator that fits over the nose and mouth and utilises the paper based filter media to remove mechanically generated (P1) or mechanical & thermally generated (P2) particles from the environment.
Fit Test Kits
Fit testing your tight fitting half or full face respirators is now easier than ever. The Bitrex® Qualitative Fit Test Kit is a qualitative respirator fit testing system which uses the harmless bitter taste of Bitrex to determine if a respirator is properly fitted to a user.
