Zentox Photox 500 indoor air purifier reduces air contaminants in lab tests

Zentox’s Photox 500 excelled in the ability to reduce airborne contaminants in recent tests performed by EMSL Analytical, Inc., the nation’s largest environmental testing firm.

Tests were performed to determine the effectiveness of the Photox 500 in the reduction of formaldehyde concentration, ammonia concentration, viable Stachybotrys sp. (black mold spores), and Bacillus in indoor air.

The Photox 500 is an advanced air purification system for the reduction of indoor airborne microbiological and volatile organic compound (VOC) contaminants. Based on photocatalytic oxidation technology (PCO), Photox is designed to remove noxious odors, toxic vapors and infectious organisms from the indoor environment.

In the volatile airborne chemical vapors tests, the Photox 500 reduced concentration levels to far below established OSHA exposure limits. In the formaldehyde test, reduction became evident after two minutes of operation. After 30 minutes of use, the formaldehyde concentration dropped from 5 ppm to .2 ppm. Ammonia levels were also reduced after two minutes of operation and went from 60 ppm to 9 ppm after 30 minutes and to 2 ppm after 60 minutes. For formaldehyde and ammonia, OSHA exposure limits are .75 ppm and 35 ppm respectively.

The Photox purifying system also reduced the concentration of viable Stachybotrys sp. after 60 minutes and Bacillus sp. after 120 minutes of operation. The bacillus species are members of the same genus of the species that causes anthrax, bacillus anthracis.

Photox also effectively removes a variety of hazardous and objectionable airborne contaminants including other bacteria, virus, mold spores, cleaning solvent vapors, paint odor, hydrogen sulfide, urine/fecal odors, cooking odors and carbon monoxide.

“We are very pleased with the lab results, which show that the Photox 500 is an excellent solution for the elimination or reduction of a variety of indoor airborne odors and contaminants,” said Bob Kim, Zentox marketing director.

Photox is ideally suited for air purification in food processing plants, hospitals, schools, office buildings, medical offices, laboratories, poultry grow-out houses/hatcheries, restaurants and nursing homes.

Safe to use, Photox does not emit any harmful products or ozone. Destruction of contaminants occurs completely inside the unit. Photox is easy to operate and maintain. The system simply requires annual replacement of lamps and catalytic reaction modules.
