In view of this, GAF Technologies has successfully developed the world's first car cabin filter using HEPA (High Efficiency Particulate Air) filtration technology, similar to the type used in laboratory cleanrooms and hospital surgical rooms. Using this patented technology, CaireFresh™ Car Cabin HEPA filters are designed to capture airborne allergens such as dust, mold, pollen, viruses and bacteria while neutralising odors and gases. Installed at the return air of vehicle air-conditioning system (located behind the glove compartment), the filters provide both passengers and driver with a cleaner and healthier environment while on the road. CaireFresh™ Car Cabin HEPA filters are able to capture particulates as small as 0.3 to 0.5 microns effectively within minutes while maintaining the flow of cooled air in the car cabin. Comparative laboratory analyses indicate that the CaireFresh filters are at least 3 times more effective than original car cabin air-conditioner filters. Another feature of the CaireFresh filters not found in original car cabin filters is the anti-bacterial property which inhibits the growth of bacteria and mold on the filter Product Features: 1) Patented technology - HEPA filter media that contains electrostatic charged Polypropylene (PP) fibers. 2) Excellent filtration capability up to 99% with low air resistance. 3) Contains anti-bacterial reagent (US EPA registered) that inhibits the growth of fungi, mold and bacteria on the filter media. 4) Captures airborne allergens such as pollens, dust, mold, viruses and bacteria effectively in the car cabin. 5) Neutralises odors and exhaust gases. 6) Easy to install and replace.
