Considerations Prior to Purchase

Portable HEPA fans and filtration systems remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns (µm), but is not a complete solution to mitigating risk of disease transmission. These should be used in conjunction with other mitigation efforts, such as masking, social distancing, hand washing and improved building ventilation systems.

  • Certification: Look for units with HEPA filters and ASHRAE certification
  • Sizing: Ensure the unit(s) you purchase is adequate for the square footage of each classroom. Larger spaces may need more than one unit. Use the calculator below to help determine needs.
  • Delivery Rate: Look for units with a clean air delivery rate of (CADR) 350-425 cubic feet per minute and AHAM verification
  • Noise: Look for quieter versions for less classroom disruption, such as units with a radial intake of air
  • Filter Replacement and Maintenance: Units include a filter that should be replaced and other maintenance may be required per the manufacturer’s recommendations.
  • Not Eligible: Units with ionizers are not eligible to be purchased with this grant
