What are HEPA filters?

HEPA filters are the most efficient filter for removing tiny particles which can otherwise penetrate deep into the lungs causing many of our well known and other lesser known health problems.

HEPA is an acronym for High-Efficiency Particulate Air.

The Australian Standard AS4260-1997, defines the HEPA filter as a disposable, extended (concertina) media having minimum filtration efficiency of 99.97% of particles that have a size of 0.3 microns.
