The Tight Seal Filtering Hardshell Mask

This is the hard-shell respirator that provides a tighter seal and better fit than most cloth and disposable masks while protecting against up to 98.6% of 2.5 micron particles (when tested at 32L/min). It fits snugly over your nose and mouth, with a medical grade silicone seal that helps ensure incoming air passes through its filter and adjustable silicone straps provide a snug, yet comfortable fit. The mask’s triboelectric charged filtration system traps germs, allergens, and pollutants as small as 0.1 micron; independent lab testing confirmed filter material efficiency greater than 99% with particle sizes from 0.1 to 0.5 microns at 236L/min. Exhaled breath is released through exit valves at the bottom of the mask to help prevent glasses from fogging. The durable polycarbonate plastic shell can be hand washed, submerged in boiling water, sanitized with disinfectant wipes, and is even dishwasher safe. Includes interchangeable blue and white shell covers and eight disposable filters. Each filter lasts up to two weeks with normal use.
