SUMFOUND Single-Layer Single-Frame Mask

The SUMFOUND™ Single-Layer Single-Frame mask (SLSF mask) is the world's first single-layer mask. It combines a single-layer filter and a frame to make a mask that is more comfortable than surgical mask and N95 mask.

·  Normal type and enhanced type

·  HPI (normal type) is 100 times higher than that of surgical mask.

·  Breathing resistance is 50%~80% lower than that of N95/KN95 mask.

·  Cost (normal type) is similar to surgical mask.

·  Plastic pollution is reduced by >60% comparing with surgical mask.

·  Convenient, lightweight, disposable design

·  Suitable for all people, including babies, children and elderly

·  The single-layer mask has electrostatic adsorption function, which greatly reduces the risk of virus shedding. The outer non-woven fabrics of the traditional three-layer mask would absorb the virus when wearer breathe in, and the virus would fall off when wearer breathe out.

Due to the low breathing resistance, single-layer masks (single-frame and double-frame) can also be worn while sleeping, making them very suitable for use in families, dormitories, and military camps to prevent the spread of COVID-19.
