Usage Tips for 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. If you are a user at high risk or would otherwise like to ensure minimal leakage, please consider doing a quantitative fit test to find the respirator mask that works best for you - please use a search engine to seek out a "fit testing service provider" in the city nearest you. These typically cost $60-$100.
Remove your respirator mask touching only the ear loops/headbands. Wash hands.
Storage: Between wearing, leave the respirator exposed to room temperature air so it may dry out. Don't place inside a bag until it has completely dried out.
The Importance of Fit: Air leaks around the perimeter of a respirator mask are a sign of a bad fit, and must be corrected! Leaks can significantly degrade the effective filtration of a respirator mask. Here is a great video from Mask Nerd Aaron Collins to explaining the importance of finding a good fit and how to check for air leaks.

Healthcare Use: typically requires ASTM F2100 Level 2 or 3 rating for bodily fluids protection, and may require CSA or NIOSH surgical respirator rating. In our store please note:
- Vitacore CAN99 9500 and Layfield 95PFE-L3 (earloop + headband) have ASTM F2100 Level 3 rating. All others haven't been tested to ASTM F2100 criteria.
- Vitacore CAN99 9500 and Layfield 95PFE-L3 (headband) have CSA Surgical Respirator certification. All others haven't been tested for CSA certification.
- Vitacore CAN99 9500 has NIOSH Surgical N95. All others are ineligible for this certification.
- Unless mentioned above, respirators in our store are not intended for professional healthcare use
Caution: No single piece of PPE such as respirators, goggles, gloves, etc. offers 100% protection.
For disposable respirator masks: Dispose prior to 8 hours of accumulated use to avoid growth of bacteria, mold, and mildew in the mask, and to avoid fatiguing in the nose wire and earloop/headbands which could cause higher leakage. Do not wash. Washing may disrupt nonwoven fibers by moving them or disrupting their electrostatic properties, reducing filtration efficiency.
Cloth Masks and Filters
Please discontinue use of cloth masks and filters in favour of a well-fitting respirator mask.
