Indoor Air Quality



Introducing our most advanced whole-house air treatment system yet. APCO-X is the result of ten years of APCO development. It will revolutionize indoor air quality with significantly improved performance, functionality, and reliability.


    • 33% more effective than previous model in laboratory tests

    • V-Twin element with over 65% more effective carbon surface area

    • EverCarbon™ cells with proprietary antimicrobial nanotechnology

    • 3 year UV-C lamp

    • LED status and lamp fault indicator

    • Translucent polycarbonate housing

    • Face-plate rotates for vertical or horizontal installation


Validated Ozone Free

Fresh-Aire UV APCO is the first UV/PCO based air purification product line to achieve the UL environmental claim validation (UL-2998) which identifies air purification systems that emits zero ozone. They are then listed in the UL SPOT database of sustainable products.

Complete IAQ Solution

APCO® whole-house air treatment systems detox the air as it is circulated by the HVAC system. They feature a unique combination of UV-C light and activated carbon which achieves unmatched microbial and odor reduction without producing any harmful ozone.

APCO-X can be combined with Freshaire UV's Purity Low Profile polarized electronic filter system for a complete and comprehensive indoor air quality solution.


    • VOC Chemical vapors and odor

    • Mold, bacteria, viruses, and allergens

    • Particulates, dust, pet dander, spores, dust mites etc.

APCO® is proven to safely reduce both VOCs and biological contaminants inside the air system and throughout the home. We carry a full line of Fresh-Aire UV Products. Contact us for more information about what's best for your home or business.

iWave (1)


With technology installed in over 100,000 applications, iWave-R is the world's first self-cleaning, no maintenance needlepoint bi-polar ionization generator designed specifically for treating air in residential duct A/C systems. As the air flows past the iWave-R, positive and negative ions actively purify the supply air, killing mold, bacteria and viruses in the coil and living space. The ionization process also reduces allergens, smoke and static electricity, as well as controlling odors (cooking, pet, VOCs) and other particles (no more sunbeams) in the air without creating ozone or any harmful byproducts.
iWave-R treats the air in any brand of residential duct air conditioning systems up to 6 tons (2400 CFM) in size with no maintenance and no replacement parts. Designed for universal mounting, the iWave-R typically installs inside or outside of duct, or it attaches magnetically near the indoor fan in the air handler. iWave-R always works at peak performance, producing over 160 million ions/cc, more than any other ionizer product on the market. Its patent-pending self-cleaning design includes a programmable cleaning cycle that can clean the emitter brushes every 1, 3, 5 or 10 days. The iWave-R is factory set to clean every third day, which is adequate for a typical installation. iWave-R does not create "black walls" as negative-only ionizer products will do.
