Usage and Cleaning of Face Masks and Filters


Avoid shared airspaces and close contact whenever possible!

Wear your disposable respirator mask or your cotton face mask with filter whenever sharing a closed airspace or coming within 2 metres of others - even outside. 

Minimize Leaks: Each time you don either mask, press aggressively downwards on the metal nose piece with two hands until it bends to fit the nose and face tightly with a good seal. Adjust the ear loops to maintain comfortable tension pulling the mask against the face. To tighten respirator ear loops on smaller faces, tie a knot in each side or use a Strap Extender such as this one.

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

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

Mask Cleaning

  1. For disposable respirator masks: Dispose after 8 hours of 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 and damage the logo. Do not wash the filters as this reduces filtration efficiency.
