The air version of PCO is NOT at replacement for filters. Filters are irreplaceable and necessary to remove large airborne particulate. Some High efficiency hepa filters can remove micron sized particles. They will get plugged up and require replacement. Activated charcoal absorbs VOC’s just like the PCO. They do it by absorption, and will need to be replaced when full. Nano Fotocide never needs replacement. To maintain check the UL bulb and rinse the honeycomb maze with water from a hose during regular preventative maintenance.
The best hepa filter operates at the micron level of particle filtration. A micron is 1/1,000,000 (millionth of a meter).
PCO operates at one billionth of a meter. 1/1,000,000,000 of a meter at the size of the pollutant molecule.
A sample of the efficiency:
Airborne Bacteria:
99% in once pass. These include Asthma, common cold and flu, Hay fever, Legionnaires disease, smallpox, and mold.
Decompose low concentrations of total volatile organic compounds:
97% in one pass. These can include benzene, carbon tetrachloride, chloroform formaldehyde, toluene, and xylene.
To put this in perspective formaldehyde is found in homes, and comes from paint, rug glue and the preservative in construction lumber.
Applications include:
Homes, offices, factories, hospitals, dentist offices, emergency rooms, airplanes, waiting rooms, anywhere where people want to breathe disinfected operating room pure air.
