Air pollution poses a significant danger to drivers and passengers, whether in public or private vehicles. It can be up to 10 times worse inside a vehicle than outside and, over the period of a year, is equivalent to passive smoking of 1,000 cigarettes. In the event of a pandemic, public transport also acts as a super spreader.
Rensair’s air purification technology can be applied to driver cabins, car headrests and buses/train carriages, making travel safe for everyone.
Exhaust fumes and air pollution take a massive toll on the health of professional drivers. Just a few hours a day can expose your drivers to constant air pollution, as well as short-term spikes. Toxic gases and microscopic particles enter vehicles through their ventilation systems, or straight in from open windows. These deadly particles damage the respiratory tract lining, enter the bloodstream and make people more vulnerable to infection, while also suppressing the immune system.
The impact of sick days disrupts timetables, damages the reputation of businesses and affects the bottom line. Clean air improves concentration at the wheel, while reducing the risk of accidents and the occurrence of sick days.
Rensair’s AirBubbl provides purified air for vehicles, delivering 38 cubic metres of clean air every hour / 22 cubic feet of clean air per minute, hence increasing air quality. Its flexible design means it can be instantly attached to and from car seat headrests or mounted in driver cabins.
Using ground-breaking, triple action technology, AirBubbl provides a non-stop shield against both particulate matter and noxious gases:
A resting adult breathes around 6 litres of air every minute. If a person sitting in a crowded bus has a viral infection such as Covid-19, the air they exhale will be contaminated with hundreds of thousands of tiny droplets that spread rapidly. Within a few seconds, these droplets can travel more than 2m from the virus carrier. Every six seconds, the contaminated air increases by another litre.
In a bus, opening a window to aid ventilation can add to the problem by increasing air turbulence and projecting airborne pathogens into the faces of other passengers. Traditional ventilation systems rely on mixing the air inside the cabin. In the case of airborne viruses like Covid-19, mixing means cross-contamination. The best way to address the problem is to extract the air that people exhale as close to them as possible and clean the extracted air before it is released back into the cabin.
AirLoop is a first-of-its-kind system that extracts the potentially contaminated air exhaled by passengers and delivers thousands of cubic metres of clean air per minute. Instead of extracting air at a single point in the cabin, AirLoop extracts and cleans air over the entire length of the bus, which helps to drastically reduce the transmission risk of airborne viruses.
AirLoop not only removes airborne pathogens, but also many other harmful air pollutants and gases including PM10, PM2.5, PM1, Toluene, Xylene, other VOCs, Ozone and NO2.
Sitting along the entire length of a vehicle’s ceiling, AirLoop is a passive system that uses the momentum of the airstream from a standard ventilation system without further mechanical intervention. The specially designed and patented diffusers inside AirLoop use negative air pressure to create a constant cycle of clean air circulation.
The system uses a uniquely engineered mixing chamber, causing air to be pulled through a high-grade multi-pollutant filter and into the device. It is mixed with the air from the ventilation system and delivered back to the cabin space, preventing contaminated air from spreading across rows. This, combined with the thermal plume generated by passengers, makes AirLoop highly effective in removing aerosols exhaled by passengers.
AirLoop ensures that, no matter where in the cabin the source of bioaerosol particles is located, the contaminated air is removed and cleaned before it can infect other passengers. This patent-pending system is the only technology that can achieve this in a cost-effective way.
The data from this trial demonstrated the performance of Rensair’s AirBubbl air purifiers in reducing in-cabin air 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.
HATS installed 100 AirBubbl air filtration devices from Rensair to protect its drivers and passengers from London air pollution. The installation added an additional layer of protection for its workers from exposure to coronavirus, as its vehicles are repurposed to support London hospitals, including Chelsea and Westminster NHS Foundation Trust and St George’s Hospital.
