Usage and Cleaning of Face Masks and Filters


Wear your Canada Strong face mask with filter whenever sharing an indoor airspace or coming within 2 metres of others. Use a Filti filter for extra droplet absorption.

Minimize Leaks. Press downwards on the metal nose piece until it bends to fit the nose and face. Adjust the ear loops to maintain comfortable tension pulling the mask against the face. 

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

Leave your filter inside your mask until it has accumulated 8 hours of use or you feel the mask is no longer clean - whichever comes first. Between wearings, leave the mask with filter on a counter in room temperature air so it may dry out. Don't leave mask and filter inside a bag.

Canada Strong products are not intended for professional use in healthcare or high risk environments. For such situations, use a properly fitted N95 respirator.


  1. Remove and dispose of the filter after 4-8 hours of accumulated usage. Do this gently in an outside airspace e.g. a garage, front porch, or hallway. Promptly wash the mask and wash or sanitize hands. 
  2. Hand-wash or machine-wash the mask in warm soapy water. Promptly wash or sanitize hands. 
  3. Hang-dry the mask for best results. Machine-drying may cause shrinkage.
