As recommended by the WHO (World Health Organization) and Dr. Theresa Tam to wear a 3 layer mask.

Convert your 2 layer mask to a 3 layer mask by inserting this into the filter pocket, this soft non-woven Polypropylene fabric (also called interfacing / interface).

Polypropylene Filter Fabric has been LAB TESTED - results provided up to 84% filtration for a single layer of this product (also called interfacing / interface). Reusable and Washable.

- - - - DETAILS - - - - :
- 100% (68 GSM - Grams per Square Meter or Two Ounces per Square Yard) Non-Woven Polypropylene
- LAB TESTED RESULTS: PFE* is up to 84% @ 0.1 micron for a single layer of this fabric. Keep in mind that when you use it with your existing cloth, it will increase the rating per additional fabric layer. This is a non-medical solution that provides a high level efficiency of protection to the community.
- * PFE (sub-micron Particulate Filtration Efficiency) represents the percentage of submicron particulates filtered at 0.1 microns (the virus is measured to be this size). PFE is the measure of the efficiency of
the mask in filtering particles passing through it. The size of the particles filtered is critical.
- Spunbonded Polypropylene: Has a fabric like feel that is soft yet structured; It is washable & will NOT divert supply of medical-grade polypropylene from medical professionals.
- Non-Woven: Have a random arrangement of fibers, like spaghetti on a plate. This randomness enables high particle filtration while remaining highly breathable.
- Thermal Bonding Texture: The filter has a pattern/texture that is done with a heated roller. The randomly oriented fibers are compressed and melted together in a pattern of small, closely spaced welds, called point bonds.
- Compliance: This product COMPLYS with ASTM F2299 standards :: https://www.astm.org/COVID-19/index.html
- Hydrophobic: Spunbond material is Water Repelling for maximum protection against fluids. Filter will not absorb moisture but rather repel it causing optimal moisture resistance by breath or other factors.
- Formaldehyde free
- It does NOT mold or deteriorate in the presence of bacteria, mold or other elements.
- Size: 5" x 6.5" (12.7cm x 16.5cm); some people might be able to get two filters out of one sheet depending on the size of your mask. Can be cut to fit perfectly inside a two-layer mask with a filter pocket
- Convert your existing masks from 2-layer to 3-layer to make them more effective in blocking particulates
- Care Instructions: Washable up to 50 *C machine wash , hang to dry; Reusable Eco friendly solution that you can be confident is hygienic (as opposed to letting your disposable filter hang out in the sun to be reused - a solution that other filter sellers are offering).
- No Shrinkage or Fray when washed; No Lint.
- Non Fusible (Fusible typically has plastic in it which does not make it ideal)
