Study claims Agion product improves indoor air quality

The five-month study trialled the effect of Agion treated ALPactive HVAC tubing ducts from ALP of Bergamo Italy on indoor environments. Agion Technologies is a provider of silver-based antimicrobial solution, while ALP manufactures aluminum pre-insulated ducting systems.

Scientific studies indicate there are many sources of pollution inside buildings and these pollutants may remain in recycled air, thereby exposing people to air containing fine dusts, moulds and bacteria.

The growing use of air-conditioning systems in public and private buildings aggravates this risk, especially when these systems are not correctly installed or regularly serviced.

Tests were conducted on samples of particulate collected from the Agion ALPactive ducts and the untreated ducts for different microorganisms including L. pneumophila, E. coli, and Staphylococcus aureus moulds and yeasts. In all micro-organisms tested, the percentage reduction on the Agion ALPactive ducts ranged from 99%-100%. In addition, the values of bacterial load found in the air emerging from the Agion coated ducts were five times lower than the load found in the air from the untreated ducts.

“The results of the study validate the important role that Agion’s natural antimicrobial protection can play in creating clean air for indoor environments,” said Paul Ford, ceo of Agion Technologies.

“ALP is proud to offer ALPActive ductwork that incorporates Agion technology,” said ALP president Giuseppe Librizzi. “With indoor air pollution a major cause for concern, it is clear that all HVAC systems should utilize available technologies that reduce the amount of contaminants found in the air.”

Results from the study – ‘Silver zeolite antimicrobial activity in aluminum heat ventilation air condition ducts’ have been published in the Journal of Preventative Medicine and Hygiene.

Researchers conducting the study were from the Italian Ministry of Health and the University of Genova.
