What Our Experts Think
-
Inspect Before and After Use: Check the facepiece, straps, valves, and lens for cracks, tears, or other damage. Ensure all components are securely in place and the seal is intact.
-
Clean Thoroughly: Wash with warm water and mild soap after each use. Rinse completely and let it air dry in a shaded area — avoid direct sunlight or heat sources.
-
Check Filters/Cartridges: Ensure filters are properly connected, undamaged, and within their expiration date. Replace as needed for continued protection.
-
Seal Test: Perform a positive and negative pressure test before use to confirm an airtight fit. Adjust the head straps if necessary.
-
Store Properly: Store the respirator in a clean, dry, and cool space. Avoid folding the mask or stretching the straps to preserve its shape and fit.
