OCS, a global Facilities Management company, tested Rensair air purifiers over a 4-week period as they increased office capacity from 5% to 100% in their poorly ventilated building. Rensair calculated an air purification solution for their offices, achieving the WHO guidelines using Rensair Core air purifiers. The high quality air sensors that took readings of CO2, VOC, temperature, humidity and PM1, PM2.5 and PM10 particulate matter saw a steady rise of CO2 as more employees occupied the building. This was understandable given the poor ventilation. However, the data demonstrated that when the Rensair air purifiers were installed and turned on, the Particulate Matter readings of PM1 and PM2.5 dropped to less than 1mg/m3. Furthermore, the PM readings remained at negligible levels throughout the trial period as the occupancy levels rose to 100%.
Rensair installed a Core unit in some high occupancy, poorly ventilated classrooms (30 students + 1 teacher), together with some high quality air sensors. Unlike the OCS case study, a Rensair unit only delivered a third of the WHO guidelines in the classrooms due to limited budgets. The air sensors in each classroom in this London school recorded data on PM1, PM2.5, temperature, CO2 and Noise. Despite the understandably high levels of CO2 during lessons, given the poor ventilation and high occupancy, the sensors registered negligible Particulate Matter throughout the trial, even when background Particulate Matter rose above safety guidelines. The noise generated by the units was significantly lower than the noise recorded in the room.
The data from this trial demonstrated the performance of Rensair’s AirBubbl air purifiers in reducing in-cabin pollution. The results showed a 59% and 54% reduction in Particulate Matter in simulations of light and dense traffic conditions respectively. The outcome corroborates other independent tests carried out on the Rensair AirBubbl which demonstrate its effectiveness in reducing PM and noxious gases in enclosed indoor spaces.
We’re confident that the results obtained by independent scientific laboratories, as well as our own real-world trials, can be achieved in any real-world environment.
