PAHHK Protective Silicone Face Mask comes with Filters made with Four Protective Layers:

• 1st Layer: soft non-woven material that blocks the droplets and other large particles, protects from dust
• 2nd Layer: elastic non-woven material traps small particles
• 3rd Layer: melt-blown fabric retains 95% of particles
• 4th Layer: non-woven hypoallergenic material

The mask is made out of food grade silicone and uses 4 ply disposable filters. The 3rd layer of the filter is made of meltblown non-woven fabric which is fluffy and soft. It absorbs non-oily particles from the air, increases the filtering efficiency and reduces breathing difficulty.
