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.

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.

Results : 95% Reduction of Airborne Mold, Bacteria, TVOC, and 90% Reduction of Surface Bacteria

“It is my considered observation that pureAir HVAC does provide a rapid and significant reduction of the typical contaminants tested. The levels achieved and maintained during this test were far below any known standard or established TLV. It is my considered opinion that this sustained condition would not be typical or possible without the continuous use of this product.” – Keith Roe, IAQS

Ozone levels throughout the duration of the test remained below TLV guidance and below levels measured outdoors.

Results : >99% Reduction of Airborne Mold, Bacteria, TVOC, and Odors

“It is my considered observation that pureAir HVAC in combination with an ODOGard coated filter does provide a rapid and significant reduction of the typical air and surface contaminants tested.  In my considered opinion, the sustained condition would not be achievable without the continual use of the technology represented.“

– Keith Roe, IAQS

Ozone levels were 0 ppm throughout the duration of the test.

Results : 99.98% Inactivation of SARS-CoV-2

These tests conclude that the 3000+ is highly effective at reducing the infectivity of aerosolized SARS-CoV-2 virus with a 3.71 log (99.98%) reduction within five minutes and thirty seconds (5:30) 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 minutes and thirty seconds (5:30) of operation, with a mass removal of approximately 1 logs.

While particle mass reductions of only 1 log was observed, 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.

Results : 90% Reduction of Respirable Particle Counts

“The sustained significant reduction of PM contaminants in the test area would not be expected or typical. This would demonstrate the effectiveness of the active passive technology provided by the Greentech unit. These lowered results were not exhibited in the indoor control area readings without the equipment.” – Keith Roe, IAQS

There was no detectable level of ozone.

Results : 83% Reduction of RPC and 60% Reduction of TVOC

“Nail salons are a harsh indoor air environment, with contaminants continuously being introduced. Both qualitatively and quantitatively, there was a measurable and significant decrease in all air pollutants monitored as well as the presence of odors. The ongoing source of air pollutants was ever changing and fluctuating in intensity, but the decreases that were reported were during the working day when they collectively were at their peak.” – Keith Roe, IAQS

There was no detectable level of ozone.

Results : 98.21% Bioaerosol Reduction of MS2 (*A known surrogate for influenza and SARS-CoV-2)

The 750+ Wall Mount was effective at reducing the aerosolized MS2 virus by an average net log of 1.86 ± 0.38 (equivalent to 98.2053% ± 1.6532% reduction) within 4 hours (240 min).

This device is capable of reducing the bio-aerosols in air.

Results : 97.0% reduction of surface mold and bacteria and 90.0% reduction airborne mold and TVOC

“It is my considered observation that 750+ Wall Mount in combination with an ODOGard coated pre-filter does provide a significant reduction of the typical air and surface contaminants tested. ASHRAE provides guidance as to the use of supplemental air purification and disinfection equipment after increasing fresh air ventilation rate to a minimum of 6 air changes per hour and filtration levels to a MERV 13 level. This study was performed without those improvements. It is my considered opinion that if this unit was used within the current ASHRAE guidelines an even  greater efficacy could be expected.” – Keith Roe, IAQS

Ozone levels were 0 ppm throughout the duration of the test.

Results : 95.0% reduction of TVOC

“It was observed and recorded throughout the project that the introduction of ozone as part of the AOP process produced the best overall reduction of contaminants and sustained air quality. There was a significant reduction of TVOC and HCHO from the initial readings which would not have been expected to occur without the introduction of this combined technology.” – Keith Roe, IAQS

Ozone levels throughout the duration of the test remained below TLV guidance and below levels measured outdoors.

Results : Achieved improved air quality that remained within targeted levels for healthy indoor air.

“It is my observation that the areas containing units demonstrated a more desirable IAQ when compared to outside conditions  and controlled spaces that were more variable and often elevated in that urban setting. The occupied classroom presents a significant IAQ issue that would benefit from air purification as it consistently showed TVOC levels higher than recommended by healthy air standards.” – Keith Roe, IAQS

Ozone levels were below detectable levels throughout the test period.

“It is my observation and considered opinion that the Greentech technology had a significant affect on stabilizing the indoor air environment as well as definitively reducing airborne contaminants as defined by the readings. No single technology alone would produce those results.” – Keith Roe, IAQS

Ozone levels were below detectable levels throughout the test period.

Results : 90.0% reduction of TVOC and >99.99% reduction of mold spores on fan/coil

“The use of the pureAir PTAC unit completely removed the viable mold spores found on the fan housing and coil surfaces of the PTAC units. These results were the same whether the PTAC unit was operated continuously or as to temperature demand. The total mold spore counts in each room were also significantly reduced from previous levels and as compared to control levels. PM2.5/PM10.0, RPC, and TVOC were also reduced to untypically lower levels.

It would be my considered opinion that pureAir PTAC would serve as an effective deterrent to mold growth on and in a PTAC unit. It would also be expected to produce a sustained and improved overall indoor air quality within the serviced areas.” – Keith Roe, IAQS
