Step 3: Ozone treatment
Once or twice during the operation of the ozonator it is advisable to set the ventilation system of the car on a closed circuit and run fans for about 15 minutes. This will cause the ozone is sucked into the ventilation ducts to remove odors from the ventilation system of the car. If you know that a bad smell comes from the ventilation system, for example from air-conditioning evaporator, then it is necessary to run the fans at the beginning of ozone treatment to effectively remove odor. If the batteries will cope, you can run the fans while the car engine is switched off - but it depends on the car.
Required time of ozone treatment depend on type of odor, intensity of the smell, the size of the vehicle, and other factors . In fact, every case is a little bit different. To check the results, you can stop ozonation, for example after 30 minutes - turn off the ozonator, let fresh air get into the interior of the vehicle, and check "organoleptic" if the odor from the inside has been removed. Perhaps you can stop the ozonation at this stage but maybe procedure must be repeated several times to get a more satisfactory result.
Step 4: After ozone treatment: "The residual smell of ozone"
Ozone treatment in enclosed spaces often leads to what is known as "residual smell of ozone" . It is a fragrance similar to the odor of ozone, but in fact is a smell of residues (byproducts) after reaction with ozone. It usually appears when the ozone treatment byproducts accumulate on soft surfaces (eg textiles, carpets) It is a temporary smell that disappears after some time. To speed it up, you can try the following:
- intensively ventilate the interior of the car: ride with the windows down, park with the windows open for a few hours
- wipe with a damp cloth dashboard, seats, etc.
- vacuum the floor mats
Please note that both the ozone and carbon monoxide (exhaust fumes) can be dangerous in enclosed spaces . If you are going to ozonate car, which is parked in the garage, be sure to open the door to the garage when you need to start the engine. Ozone can also get out of the interior of the vehicle to the garage, so take the appropriate precautions.
