  • HEPA Filters: What is Yours Actually Doing?
    It is common knowledge that to have a clean environment inside a biosafety cabinet or clean bench, you have to have HEPA-filtered air. Presumably, the filter removes all contaminants, but does it really? How does a HEPA filter work? Are all HEPA filters created equal?
  • When Should HEPA/ULPA Filters be Changed?
    Filter Change Criteria There are 3 basic reasons to replace HEPA filters: The filter is too clogged to meet the required air flow for the system. The filter fails a required filtration test. To reduce operating costs.
  • Handling, Installation and Burn-off Procedure for HEPA Filters
    HEPA Filter = High Efficiency Particulate Air Filter. High means 99.97% or higher. The efficiency is a measure of how effectively the filter traps particles. It is calculated by dividing the number of particles trapped by the total number impinging on the filter. Fewer than 3 in 10,000 are allowed
  • Air Filtration and the Use of HEPA Filters in Biological Safety Cabinets
    In biological applications, laboratory personnel regularly work with microorganisms in biological safety cabinets. HEPA filters used in these cabinets must effectively trap hazardous bacterium and viruses to provide personnel protection
  • New Model Workstation HEPA Performance Report
    The Invivo2 / Concept / Concept-M Series Workstations have been recently remodelled, and now include a standard HEPA filter. This report details the HEPA filter testing and results for the common body of these workstations to determine air cleanliness using EN ISO 14644-1 as a reference

  • Rotronic - Humidity in Clean Rooms
    A clean room is a manufacturing environment that has a low level of environmental pollutants such as dust, airborne microbes, aerosol particles and chemical vapors. The air inside is constantly recirculated through High Efficiency Particulate Air (HEPA) filters. Some clean rooms are entire
  • From Drinks to Drugs: A Proposal for Advancing Aseptic Processing and Eliminating Contamination Risk
    the enclosure is always filtered through HEPA or in some cases ULPA filters. As one would expect given this level of air filtration, there is no difference in contamination risk arising
