4-Layer Technology, not 3 like most…
The masks filter out dust and pollution particles such as PM2.5 as well as bacteria and viruses using a unique quad layer filtration system. The first layer catches larger pollution particles such as dust, followed by the Three-Ply Micro Particulate Filter which stops nearly 100% of smaller particulate matter such as PM2.5.
Effective solutions for challenging times
The mask can be hand washed with washing powder and hot water.
