HEPA

HEPA stands for High Efficiency Particle Arrestor, used to reduce the number of contaminants in indoor air. A HEPA filter will arrest or stop 99.97% of all particles .3 microns or larger. HEPA filters - used in 'clean rooms' - are essential in medicine and in the manufacture of computer components. However, they have limitations in vacuums. They tend to leak in vacuums, because they were never intended to be used as small, portable filters. They are expensive and must be discarded because they cannot be cleaned. They clog quickly and strangle airflow. And even when working perfectly, up to half the respirable particles in indoor air are small enough to go right through a HEPA filter. SuperVac makes HEPA filters redundant, because SuperVac exhausts air outdoors
