We test in EPA-certified testing chambers as well as in many tough “real world” environments, because real results are what we’re all about.
Active HEPA+ Lab Test Results
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.

Active HEPA+ Field Test Results
Extended Care: TVOC & Particulate Matter
Results : >99.9% Reduction TVOC & PM
“The initial odor level was very significant and somewhat unpleasant even when wearing a mask. I was no longer able to smell the odors through the mask by the day 3 visit. On every subsequent visit, the smell in the room would be described as typical and no longer extreme or offensive – even without my mask.” – Keith Roe, IAQS
Both qualitatively and quantitatively, there was a measurable and sustained reduction of odor and TVOC levels when the unit was functioning in comparison to the initial levels found inside the room.
When reviewing the data, it should be noted that the unit was inadvertently turned off on day 4, causing numbers to rise. Once the unit was turned back on, levels of TVOC and PM dropped again, demonstrating the Active HEPA+’s contribution to improved indoor air quality.

The proof is in the data.
Extensive testing showed similar impressive results. TVOCs were reduced 99.9% and formaldehyde (HCHO) reduced to 33% of the original concentration. Both Total Particulate Matter (PM) and Respirable Particle Counts were significantly reduced during testing.
Commercial Offices : Mold, Bacteria, TVOC, & Odors
Results : >99.9% Reduction of Airborne Mold, Bacteria, TVOC, and 99.9% Reduction of Surface Bacteria and Odors
“It is my considered observation that over the duration of this study, with the expected environmental fluctuations that occurred in a real-time setting, this study indicates that Active HEPA+ coupled with a standard MERV 10 HVAC filter at minimal air turns per hour produces results that substantiate an overall high degree of efficacy. This high rate of efficacy was achieved within the first 24 hours of operation even at lower air turn rates. This would not be expected or typical.”
Ozone levels throughout the duration of the test remained below TLV guidance and below levels measured outdoors.

Extended Care: Mold, Odors, & TVOC
Results : >99.9% Reduction of RPC & Odor Intensity
“The indoor air quality of Room 208 was reported to be heavily laden with untypical levels of odors, volatile organic compounds (TVOC), formaldehyde (HCHO), PM 2.5 (particle mass) and RPC (respirable particles between .3 and 10.0 microns). After operation of the Greentech HEPA+ Pro unit, these levels were quickly decreased and were sustained at lower levels more consistent within current Guidelines and Standards.”

Extended Care: Mold, Odors, & Ozone
Results : >90.00% Odor Elimination. Significant and sustained reduction of PM & RPC counts.
“This room presented a challenging environment, occupied by two incontinent male patients and serviced only by a ductless wall unit with an unrated pre-filter. The related spikes observed in odors and other pollutants during testing did not linger and were ultimately reduced and sustained. Also, the significant and sustained reduction in PM 2.5/10.0 and RPC counts was a direct result of the efficacy of the ODOGard HEPA filter. These pollutants represent some of the most significant respiratory health concerns in a healthcare facility as well as airborne diseases.”
