Usage and Cleaning of Respirators, Face Masks, and Filters

Usage of Respirator Face Masks

Avoid shared airspaces and close contact whenever possible!

Wear your disposable respirator mask whenever sharing a closed airspace at any distance, or when outside and coming within 2 metres of others.

Minimize Leaks: Each time you don a respirator mask, ensure the mask nose bridge is formed tightly against the nose by pushing inwards firmly with fingers from both hands. Ensure the ear loops are snug for a tight seal between the mask and face, especially around the nose. For smaller faces, try tightening the ear loops using cord locks or a strap extender or tie a knot in the earloops. If air leakage persists around the edge of the mask, please discontinue use and seek a better-fitting respirator mask.

Removal: Remove your respirator mask touching only the ear loops, one ear at a time. Wash hands.

Storage: Between wearing, leave the respirator exposed to room temperature air so it may dry out. Don't put any masks inside a bag before they have completely dried out.

  1. For disposable respirator masks: Dispose after 8 hours of accumulated use. Do not wash. Contrary to some manufacturers' claims, washing may disrupt nonwoven fabrics and electrostatic layers, reducing filtration efficiency.
  2. For cotton masks: After 8 hours of accumulated usage, remove the used filter gently in an external airspace e.g. a garage, front porch, balcony, or hallway, then dispose of it. Hand-wash the mask in cold soapy water then hang dry. Do not machine wash or machine dry as this may shrink the fabric or damage the logo.
  3. For filters: Dispose after 8 hours of accumulated use. Do not wash the filters as this reduces filtration efficiency. 

Storage of Cloth Masks and Filti Filters

For cloth masks, leave your Filti filter to dry inside the mask until it has accumulated 8 hours of use or you feel the mask is no longer clean - whichever comes first.
