Mold Tests Before & After UV Air Cleaner Installation

February, 2004. Mold analysis reports before and after the installation of American-Lights^® UV Air Cleaner in residential HVAC system and continuous running of the fan for three weeks show a total eradication of five types of mold spores and dramatically reduced levels of the 4 most UV  resistant types mold in the indoor air. The lab tests confirm again that mold spore levels after only three weeks of using American-Lights^® UV Air Cleaner are negligible:

Previous mold testing reports

In April 2003 air samples were collected from a South Carolina residence by Indoor Air Quality and analyzed by PRO-LAB/SSPTM INC.

Mold Analysis Reports before and after the installation of American-Lights^® UV Air Cleaner in the residential HVAC system and continuous running of the fan show a total elimination of three types of mold spores and a dramatically reduced level of the most resistant type mold in the indoor air.

On April 4, 2003 the air samples collected by Indoor Air Quality, a Hardeeville, SC company, were analyzed for mold and mold spores counts at:
PRO-LAB/SSPTM INC.
3300 Corporate Avenue, Bldg., 112
Weston, Florida 33331
800-427-0550

The report showed a total mold spores count of 1,400 per m³. Mold Analysis Report 04/04/03

After the initial air samples were collected, an American-Lights^® Germicidal UV Air Cleaner was installed in the HVAC system. The germicidal UV light and the fan of the HVAC system were on 24/7 for two weeks before the next air samples were collected and sent to the PRO-LAB/SSPTM.

On April 18, 2003 the second air samples were analyzed and the respective report showed that three types of mold were eliminated and the one remaining type of  mold spores counted 160 per m³. Mold Analysis Report 04/18/03

This is a decrease of almost 10 times over a short, 2 week period. The resulting mold levels are either zero or negligibly low and as the American-Lights^® UV Air Cleaner works on a cumulative basis, it can be concluded that they will continue to diminish over time.
