The filter spray PuraClean transforms a conventional residential or commercial HVACR equipment media filter into a passive electrostatic filter. According to the manufacturer, the patented 16-ounce, non-aerosol filter spray, originally developed under a contract for NASA to eliminate airborne particulates and increase IAQ in the International Space Station, improves filter efficiency ranging from 200 percent to 1,200 percent for 3- to 7-micrometer particle sizes, respectively, but without affecting airflow resistance or system efficiency. The filter spray is designed to improve the performance of any type of filter ranging from reusable metal filters, expensive electrostatic filters, or inexpensive spun glass or foam filters. Less-expensive filters, which typically filter only 20 percent of airstream particulates, will receive the greatest benefit, says the company. The spray applies a dielectric insulation to the fibers so their electrostatic attraction capabilities remain. Electrostatic filters benefit from this dielectric coating, since increased dielectric insulation leads to improved filtration. The spray is a win/win product for consumers who can better rid their household of allergens, dander, dust particles, and mold spores without purchasing expensive electrostatic filter equipment, and for contractors who can sell it and add profit to service calls, says the company. Each bottle treats up to 16 filters.
