The useful service life of the filter media in the HEPA Filtration System is directly related to the volume of
air passed through the system and the amount of contaminants in the air. In a typical residential application,
Stage 1 and 2, filters should be replaced every three to six months or when needed.The Stage 3 HEPA fil-
ter should have a life span of two to five years, again, depending on the amount of particulate in the air and
the maintenance of the Stage 1 pre-filter.

Stage 1 - Prefilter: Air passes through the prefilter where larger particles are taken out of the air.
Stage 2 - Carbon: Air passes through the carbon filter where some gases and odors are removed.
Stage 3 - HEPA: Air passes through the certified HEPA media where very small particles are removed.
99.97% of all particles 0.3 microns and larger that pass through this stage are removed. Particles
smaller than 0.3 microns are also removed with less intensity.
If the air flow through your unit is noticeably reduced, you can inspect the HEPA filter by
removing it and seeing if the filter paper is darkened on the inlet or outer side. If it is, the filter
cartridge should be replaced.
