 Case Studies: Extended Care

  Active HEPA+

Location:
Extended Care Double Occupancy Room

  • Product : Active HEPA+
  • Technologies: PCO/BPI/HEPA/ODOGard
  • Test time: 14 days total – real time measure
  • Test space: 12’x22’x8’ double occupancy room
  • Test administrator: IAQS

  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.


TEST RESULTS:
NAME TYPE REDUCED
TVOC Airborne >99.90%
HCHO (formaldehyde) Airborne 67.00%
PM 2.5/10 and RPC Airborne >99.90%

  Active HEPA+

Location:
Extended Care Double Occupancy Room

  • Product : Active HEPA+ Room
  • Technologies: PCO/BPI/HEPA/ODOGard
  • Test time: 5 days total – real time measure
  • Test space: 13′ x 16′ 8’ double occupancy room
  • Test administrator: IAQS

   RESULTS: >90.0% 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.”

TEST RESULTS:
NAME TYPE REDUCED
Mold Spores Airborne 67.00%
Odor Intensity Airborne 90.00%
Ozone Levels Airborne Below Detectable

  Active HEPA+

Location:
Extended Care Double Occupancy Room

  • Product : Active HEPA+ Room
  • Technologies: PCO/BPI/HEPA/ODOGard
  • Test time: 5 days total – real time measure
  • Test space: 300 sq.ft. single occupancy room
  • Test administrator: IAQS

  RESULTS: >99.9% 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.”
