4-Stage Filter Configuration:

PermaFilt pre-filter is Stage 1, then main filter combines three additional stages of filtration:

• STAGE 1: Large Particle PermaFilt Pre-Filter (wraps around main filter)
  Cleanable re-usable prefilter traps large particles easily seen by the naked eye (dust, hair, lint, pet dander, etc) while prolonging the life of the main filter. Easy to maintain - simply vacuum clean monthly from the outside of the unit. 
• STAGE 2: Medium Particle Pre-Filter
  Removes additional small to medium sized particles (mold spores, pollen).
• STAGE 3: 15 lbs Carbon / Zeolite Blend
  Activated granular carbon/zeolite adsorbs commonly found household odors, gases and chemicals.
• STAGE 4: 60 sq ft Certified True HEPA filter media
  This final filtration stage contains 60 sq ft of medical-grade True HEPA pleated filter material. Traps up to 99.97% of particles as small as 0.3 microns that pass through the filter.
