True certified HEPA filterwith a >/= 99.97% efficiency on 0.3 micron particles.Airborne particles trapped by our HEPA filter include:Pet dander, dust, pollen, fungal spores, mold spores,bacterial spores, airborne dust mites and cockroachfecal antigens and proteins.• Fresh air features:•Tandem™** “Y” shaped transition providesa single home outlet; stale air is exhaustedand fresh air drawn in simultaneously, withoutrisk of contamination. The single hole in ahome’s exterior reduces product installationtime, materials, and cost.•AirDuo™** duo-flow, air exhaust/intake outdoorhooded air vent, plus integrated grille, featuringintegral intake and exhaust filters, eliminatesair cross-contamination. (Optional “pine treespore” filter available for mild-climates withAlpine/Pine tree vegetation.)•AirChoke™** in response to Outdoor AirTemperature; our system’s AirChoke™automatically attenuates air flows to increasesystem performance and owner comfort.•AirDiffuse™** product mixing cavity isspecifically designed to ensure proper mixingof external and internal air, which possessdiffering airflow rates, while ensuring consistentHEPA filtration and ventilation.•SoftLinkage™** damper system. TheSoftLinkage™ fresh intake and stale air exhaustdampers feature a roller cam damper systemwhich eliminates the need for mechanicalactuators, motors, and gear teeth with meshingwear-out problems, and expensive dampercontrol logic circuitry.GSVh1KFRESh AiR SYSTEMFRESH AIR SYSTEMShEPA FiLTRATioN AND FRESh AiR VENTiLATioN FoR ThE ENTiRE iNDooR ENViRoNMENT**Patent Pending•GuardianPlus™ Air Systems’ fresh airexchange eliminates excess humidity duringcold weather “heating” seasons.• Owner Interface / Electronic, low voltage ownerinterface ensures: No high voltage wiring and noelectrician required.
