Ultrafine Particle Debate Resonates with Industry Leaders at World Filtration Congress

AHG’s innovative techniques & facilities that identify, evaluate and address the potential hazardous nature of ultrafine particles have them well positioned to provide the necessary resources to the Filtration Industry.

DUBLIN, Ireland, April 25th, 2012:

AHG is a unique vertically integrated facility which combines molecular biology with state-of-the-art air sampling and particle counting in a highly sophisticated AC-1 chamber. Availing of such facilities, AHG can follow nominated viruses, bacteria, molds and other toxic ultrafine particles as they become airborne and are distributed throughout the chamber in the presence and absence of a functioning consumer product.

With core expertise in the area of preventing ill health due to indoor air pollutants, airmid scientists apply their skills to evaluate the complex interactions of biological, chemical and physical properties associated with consumer products, and provide customers with a complete solution for healthy living and label claim validation.

Data generated in this manner will have a vastly greater degree of sensitivity and specificity than any that relies on conventional culture techniques. Molecular technology also allows for quantification of residual contamination within the dehumidifier and its ability to capture any infective particulate material being shed.

“Even products that contain HEPA filters may result in consumers being exposed to bacterial fragments and other noxious particulate materials is a concern” says Fraser Hodgson, Chief Operations Officer at airmid healthgroup. “It is inevitable that media attention will continue to draw focus on negative health implications associated with Ultrafine Particles. Airmid healthgroup offers companies the opportunity to proactively address these issues”.
