Made from the same advanced materials used for N95

Our high-quality Lambs Advanced Carbon-Activated PM2.5 filters are made from 5 layers of three non-woven materials.

2 layers of Metblown Fabric, whose electrostatic properties helps it capture microscopic particulates and aerosolized nano-particles as they attempt to pass through.

1 layer of Activated Carbon that uses a process called adsorption to trap particulates, and also serves as an antibacterial and deodorizer.

2 layers of Spunbond, a non-woven fabric that filters out larger particles, while providing structure to the inner layers.

Designed for Lambs Antimicrobial Face Mask

  • Dual layered antimicrobial Wavestopper fabric with 70% anti-viral silver
  • Interior pocket for replaceable filter
  • Overhead elastic for comfort
  • Metal nose wire for a snug fit

Effective against pathogens & air pollution

Although mostly invisible to the naked eye, the air we breathe is full of tiny particles; chemicals, soil, smoke, dust or allergens, in the form of liquids, gases, or solids. Our advanced filters are effective against the smallest of these micro-particle (also known as Particulate Matter 2.5) to protect your lungs and health. Studies have also shown that masks can filter particles as small as 0.007 microns – 10 times smaller than viruses.
