AirClean – Air conditioning disinfection

According to scientific studies, allergies are on the rise – especially in developed countries. The number of people suffering from allergies has more than doubled over the past decade. A third of the population now complains about allergies. Specialists anticipate that every second person will be affected by an allergy in under ten years’ time. When you consider how much time we all spend in vehicles, it seems all the more important to take action to eliminate bacteria, germs and viruses in this environment.

While almost every vehicle is equipped with a modern filter system these days, it’s still impossible to prevent these bacteria, germs and viruses from multiplying. Cabin filters are required to filter up to 150 litres of incoming air per second. Are customers on the lookout for a professional filter system when they buy new vehicles? Or do they worry about resolving the causes of the bacteria? I don’t think so – and if they do, then not nearly often enough.

Disinfection of the A/C system

I had the opportunity to disinfect the A/C system in a Toyota Verso.
In advance, the owner and I subjected the vehicle’s interior to a thorough clean. After removing the cabin filter, I closed all of the ventilation flaps in the interior and filled every ventilation duct with mist using the AirClean. After waiting around three minutes, I consecutively activated all switch positions on the ventilation and opened all flaps in the vehicle interior.
Using the AirClean spray pistol, I continued to spray the medium into the filter box. This made me certain that the germs, bacteria and viruses had been eliminated in the area of the evaporator and in the ventilation ducts. One major advantage of the AirClean A/C system cleaner is that it utilises a mineral-based medium. It is therefore completely safe for people and the environment.

Next, I turned my attention to the vehicle interior. I fed the compressor’s air hose through the window (very slightly opened to a gap of approx. 10 mm) and set up the spray bottle between the front seats. I left the vehicle’s engine running and switched the ventilation to circulation mode. After a short while, such a curtain of mist had descended in the vehicle interior that you couldn’t make anything out any more. After around 5 minutes, I switched the compressor off and opened the doors. Upon doing so, I was greeted by a slight whiff of swimming pool; however, this had completely dissipated after 5 minutes.

The results

It’s very difficult to demonstrate a dead bacterium to a customer. You can’t really say anything along the lines of “look, it’s lying on its back with its legs in the air“! On the other hand, this test had the advantage that I was dealing with a driver who suffers from allergies herself. While driving, she always used to complain that her eyes were burning and her throat was irritated. After giving her a few tips about dealing with the A/C system, (for example that it should always be left switched on), the vehicle was cleared to be driven again. I also pointed out that she was now sitting in an allergy-free space. For 4 weeks now, she’s been driving free of complaints and is still waiting to see how long this will last.
