 Active HEPA +

pureAir Active HEPA+ Units

Test Location:
MRIGlobal

  • Product : Active HEPA+
  • Technologies: PCO/BPI/HEPA/ODOGard
  • Test time: 3:20 minutes
  • Air exchange equivalent: 10
  • Test space: Class III Biosafety Cabinet, 2.5×3.5×1.5 ft
  • Test location: MRIGlobal

Lab Test: Aerosol Deactivation of SARS-CoV-2

  Results : 99.98% inactivation of SARS-CoV-2

These tests conclude that the Active HEPA+ is highly effective at reducing the infectivity of aerosolized SARS-CoV-2 virus with a 3.63 log (99.98%) reduction within three (3) minutes and twenty (20) seconds of operation in relation to baseline control results.

These results also show that HEPA+ had a reduction in aerosol mass and median size within the three (3) minutes and twenty (20) seconds of operation, with a mass removal of approximately 2 logs.

While particle mass reductions of only 2 logs were observed, Active HEPA+ demonstrated viral infectivity reductions greater than 3.5 logs, which supports the hypotheses that both active and passive technologies contribute to overall product efficacy.


pureAir 3000+

Test Location:
MRIGlobal

  • Product : pureAir 3000+
  • Technologies: PCO/MERV/ODOGard
  • Test time: 5:30 minutes
  • Air exchange equivalent: 10
  • Test space: Class III Biosafety Cabinet, 2.5×3.5×1.5 ft
  • Test location: MRIGlobal

Lab Test: Aerosol Deactivation of SARS-CoV-2

  Results : 99.98% inactivation of SARS-CoV-2

These tests conclude that the pureAir 3000+ is highly effective at reducing the infectivity of aerosolized SARS-CoV-2 virus with a 3.71 log (99.98%) reduction within five (5) minutes and thirty (30) seconds of operation in relation to baseline control results.

These results also show that 3000+ had a reduction in aerosol mass and median size within the five (5) minutes and thirty (30) seconds of operation, with a mass removal of approximately 1 log.

While particle mass reductions of only 1 log was observed, pureAir 3000+ demonstrated viral infectivity reductions greater than 3.5 logs, which supports the hypotheses that both active and passive technologies contribute to overall product efficacy.
