3. The Water Repellent Test
1. Syringe water droplets in the centre of the 3-ply or 4-ply face mask's inner surface.
2. Repeat Step 1 on the face mask's outer surface.
Face Mask's moisture repellent filters will repel the water droplets from seeping into the masks and leaking out from below.
Research shows that people without symptoms or who have yet to develop them may be able to spread the disease.
The reusable cloth mask without filters is said to be 50 - 60% effective to filter out the bacteria, compared to the reputable surgical masks which claim Bacterial Filtration Efficiency (BFE) of 95% or more.
The Face Mask has moisture repellent filters. With such filters repelling respiratory droplets from the wearer and from the outsiders, there will be much higher % of protection. The 3-ply has one filter while the 4-ply has two filters.
The reusable face mask is washable, saving you money and the environment compared to the single-use disposable surgical masks. Wash it daily in soap and cold water. Hang to dry. Soft iron heat onto the cloth mask. Do not use bleach or detergent.
It is sold at accessible prices. It is recommended to be used for 30 washes. Face Masks for Children are top sellers.
