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.
