1. Surgical and Medical Masks

While N95, surgical, and medical masks remain the best filters for airborne particles, they should be worn only by medical professionals treating patients with COVID-19. Health care professionals that have access to these masks can insert medical masks into the pockets of a Nathon Kong silk face mask to stay protected while still wearing a mask that is fashionable.

2. Coffee Filter or Tea Filter

Since medical masks are reserved for medical professionals, each Nathon Kong face mask comes with a coffee filter already included in the pocket between the two layers of fabric. Coffee filters and tea filters are the most widely recommended filter to be used in a protective face mask. Their shape is ideal for covering the entire mouth and they have the best filtration capacity out of household materials. Coffee filters accumulate moisture and can only be used once before needing to be discarded.

Coffee filters are great for face masks, but have to be discarded once used.

3. HEPA Filters and Vacuum Bags

HEPA filters are made to be very effective in containing particles in the air. They are commonly used in vacuum filters. They are highly effective mechanical filters that block over 95 % of all particles as small as 0.3 microns. HEPA filters also allow for easy breathability.

There is some debate on the usefulness of HEPA filters and vacuum bags as face mask filters. Some doctors recommend making homemade masks from vacuum bags. Others warn that some vacuum bags are made with pieces of fiberglass. Not all vacuum bags are made this way, but inhaling fiberglass can be dangerous, especially if the bag is cut to be used as a filter as it releases the chemicals that make up the bag. If you plan to use a vacuum bag as a filter, check to make sure it does not contain any harmful materials in them.

4. Pillowcases

The fabric that most pillowcases are made from have shown to be a very effective air filter that you can find at home. Scientists found that pillowcases filter about 60% of aerosol particles when folded in four layers. Pillowcases can also be washed and reused.

5. Paper Towels

Paper towels are probably the most accessible material that can be used as a filter. A team of researchers at Smart Air Filters tested how effective several household fabrics were at filtering microscopic particles and how easy it was to breath through each fabric. They concluded that paper towels offered an ideal balance between filtration and breathability. The researchers recommend using paper towels in combination with other materials while making a homemade face mask.

J’aurais cru qu’une partie d’une serviette hygiénique aurait été un meilleur filtre qu’une serviette en papier, qui elles aussi sont très accessibles.

Par déduction, je pense que le port d’une visière en plus d’un masque est la meilleure protection car aucun virus ou microbes ne peuvent traverser l’acrylique à condition d’exercer un entretien hygiénique.
J’ai remarqué que dans un Maxi, après m’avoir vu avec une visière en acrylique on m’a dit que ca devait être un masque que je devais porter…. par la suite les employés portent en plus de leur masque des lunettes de protection en acrylique.
