FILTER BENEFITS (10 pcs in a pack):

These high quality PM2.5 HEPA mask filters are made with 5 layers of high grade materials, which protect you in different ways:

• Layer One of non-woven cloth blocks larger airborne particles, such as pollens.
• Layer Two is made out of meltblown cloth, the same material used in respirators and surgical masks you’ve been hearing about. This material is very special because it blocks finer particles from coming in, while also allowing the air to go through, allowing you to breath.
• Layer Three is made out of activated carbon, a material used in a lot of mask filters for its efficiency in absorbing and clearing fine pollutants.
• Layer Four is also made out of meltblown cloth, for any particles that would remain.
• Layer Five which is closest to your mouth is made out of comfortable anti-static non-woven cloth
