The ProTech™ brand three-stage IAQ system, IAQ-1, utilizes the latest in contamination control technology to reduce indoor pollution by attacking particulate, microbial, and chemical contaminants. The system accepts contaminated air through the Quartzel® felt, pleated particulate filter that removes particles as small as 1 micron. The combined action of the UV ray and titanium dioxide in the Quartzel felt acts as a catalyst that reduces other impurities. The two UVC lights reduce viruses, bacteria, mold spores, and fungi, and destroy volatile organic compounds found in paints, cleaning supplies, cooking smells, and other gases. After this process is complete, clean, fresh air is distributed throughout the house. The unit has a front access door and viewport for ease of service.
