Both the filter media and the full unit met the HEPA standard, which requires a minimum of 99.97% efficiency at removing particles at 0.3 μm in aerodynamic diameter.
Conclusion
The entire Rensair unit performs to HEPA standard which is not a given. Most air purifiers using HEPA filters only remove 80-90% in one air pass due to design/leakage but this test confirms Rensairs design quality.

At 30 minutes of UV exposure, all test viruses and mould spores were deactivated. Deactivating mould does not necessarily remove the allergenic proteins found on the outside of the non-viable spores. Further testing did not detect any Stachybotrys (black mould) proteins on the filter surface.
Conclusion
Mould spores can live and grow inside a filter, and capturing them does not necessarily prevent people from having allergic reactions, due to certain proteins on the outside of the spores. Rensair’s combination of HEPA and UVC captures and completely inactivates both the mould and the proteins, making it the best solution available.

Hemispherical uniform intake of dirty air into the air purifier, at a constant velocity from above and around the 360 degree circumference of the device.
Conclusion
This shows that the directional placement of the device in a room is not important (which is not the case for air purifiers that only have a single/double sided inlet or square air purifiers).
Air purifier air outflow

ESI GROUP

Rensair Core 330

Uniform outward distribution of clean air from the air purifier at 360 degrees, at a constant velocity in ‘radial jet’ motion parallel with the floor.
Conclusion
The clean air leaves the air purifier and travels along the floor, up the walls and down from the ceiling, penetrating the entire room. This widespread toroidal air movement ensures full room circulation.
Room air flow

Room air flow

ESI GROUP

Rensair Core 330

The study demonstrates that there is no recirculation of clean air straight back into the air purifier.
Conclusion
The air purifier creates full toroidal air circulation in a room, causing downward pressure on airborne particles, which precipitate to the floor. These factors are key to efficient air cleaning throughout the entire room, rather than just around the air purifier, preventing airborne disease transmission.

REAL LIFE TRIAL

office

OCS

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%.

school

QPCS

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.

car

Delos

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.
