Ozone Gas

Ozone Gas is a safe, proven and effective agent for sanitization. It is widely used to eliminate bacteria, moulds, fungi, and viruses – including COVID-19.

Eco Friendly

Ozone Gas is produced naturally by nature itself. The Sanity System used technology to create the appropriate level of Ozone Gas to Sanitize the area, leaving the area Sanitised

The car has become a second home to many of us, we use it to transport our family, friends and pets. Over time the car’s interior can accumulate nasty smelling odours, harmful viruses and bacteria from things like cigarette smoke, smelly food, nasty pet odours, mould, sweat, vomit, mucus, saliva, blood and other bodily fluids. Making the car a very unpleasant and harmful environment to be in. Ozone is a very strong oxidant/disinfectant and because it is a gas, can quickly and effectively sanitize passenger vehicles killing germs and any nasty smelling odours, leaving the vehicle in a safer and more pleasant, clean smelling environment to travel in.

Our Ozone generators will deliver a high level of chemical-free sanitizing agents which will quickly penetrate deep into your vehicle’s seats, carpets, headlining and the whole interior, and clean anywhere air current travels, the whole process takes from around 30 minutes to complete.

Our Ozone shock treatment will provide a safer environment for travellers and leave your vehicle smelling clean and fresh, instead of using artificial fragrances some use to mask odours. Ozone treatment is the most effective sanitizing methods available today. It is a green solution because no dangerous chemicals are left behind.
