HEPA-CHECK™
Filter Challenge Particles

There is a worldwide growing demand for polystyrene latex* particles (PS) by filter manufacturers, end-users and third-party testing services. PS’s are listed as suitable test materials when using particle counters by both the Institute of Environmental Sciences (IEST) and European Norm (EN) standards.

HEPA-CHECK™ Filter Challenge Particles are polystyrene latex particles optimized for performance, aerosolization, safety and economy for both HEPA and ULPA filter testing. Unlike traditional oil-based filter test materials such as dioctylphthalate (DOP), HEPA-CHECK does not carry the health risks associated with atomized oils such as dioctylphthalate (DOP) or other oil-based filter test materials. Due to the clean oil-free nature of this ultra-pure water suspension, HEPA-CHECK is ideal for leak testing in-situ filters where the highest degree of cleanliness is required.

Our polystyrene particles, for HEPA and ULPA filter testing, are manufactured so you are ensured a consistently controllable and repeatable supply of highly uniform, monodisperse particles which meet or exceed efficiency testing requirements. Each 25 mL bottle is to be diluted in one US gallon (3.79 liters) of clean water and then nebulized. Nebulizing can be accomplished by using commercially available ultrasonic humidifi ers. Single use bottles ensure reproducible test conditions from site to site. The product is available in particle sizes traditionally associated with testing and is sold individually or in convenient packs of 6 or 20 bottles.

Applications:
  • Manufacturers: Efficiency rating and certification of filter products
  • Third-party Testing Services: In-place verification of filter efficiency and leak testing in semiconductor and pharmaceutical cleanrooms
  • End-users: In-place verification of efficiency and leak testing in your cleanroom

    Advantages:
  • Particles are non-toxic
  • Particles will not degrade filter media
  • No oily residue to contaminate cleanroom
  • Highly uniform microspheres at known sizes
  • Acceptable test materials in IEST and European Norm standards
  • State-of-the-art technology
  • Precision filter integrity testing

    Benefits:
  • Non-flammable and convenient to transport
  • Quicker returns to baseline counts than aerosolized oils
  • Reliable particle size measurement and suspension stability
  • Immediate delivery
  • Lower cost than buying bulk latex
  • Easier handling at job site
  • Convenient to open, dilute, and use
  • No negative side effects or concerns as with atomized oils
  • Consistently controllable and repeatable
