Why Buy A PM 2.5 Filter?
FACTS: Fine particulate matter (PM2.5) is an air pollutant that is a concern for people's health when levels in the air are high.
HOW IT WORKS:
A PM2.5 filter works by creating an electrostatic barrier that captures the microscopic particles that common mask fabrics like cotton and polyester can't effectively block on their own.
