1. Selling and Servicing Residential and Commercial Indoor Air Purifiers. These Photox^TM (pronounced Pho-Tox) Air purifiers are USA manufactured by the Zentox Corporation in Hopewell, VA. The Photox^TM name is derived from the Zentox patented proprietary process referred to as PhotoCatalytic Oxidation (PCO). The unique catalyst absorbs the airborne impurities. These are exposed to an UltraViolet UV-A light safely and effectively destroying hazardous and objectionable airborne contaminants including, but not limited to bacteria, virus, mold/fungi, allergens, volatile organic compounds (VOC), odors, carbon monoxide, and ozone. Once destroyed, the catalyst is effectively regenerated.

2. Collection of Indoor Air Samples for Subsequent Laboratory Analyses. The sample collection methods used follow recognized industry protocols as do the laboratory analysis procedures. Sample collection and analyses include mold/fungus, allergens, total bacteria, and virus SARS-CoV-2 (Covid 19). 

3. Consultative Review of the Indoor Air Heating and Cooling Systems. The objectives of these reviews are to provide guidance on where and how to collect indoor air samples, selection of the analysis laboratory, and where to place the air purifier(s).
