aht is a professional testing firm that specializes in on site field testing of H.E.P.A. filters used in cleanrooms. Cleanrooms are segregated areas which use H.E.P.A. filters, room pressure differentials, and laminar air flow to create a clean, particle free and static free work area. These areas should be tested to first ensure compliance with the target cleanliness class, and annually tested to ensure that all parameters have not degraded from the setpoint.

Let aht help with your cleanroom certification needs. Certification of cleanrooms must meet International standards including ISO (International Standards Organization), IEST (Institute of Environmental Sciences and Technology) standards, NEBB (National Environmental Balancing Bureau) standards, and Health Canada�s �Good Manufacturing Guidelines�. Call aht to discuss the specifics of your cleanroom requirements, and what you need to comply with these important regulations.
