So2Pure is an advance high-end grade air purification coating based on the latest nano-science technology - photo catalyst. In the presence of light, active oxygen is formed and excited on the So2Pure treated surfaces to destroy all micro-sized air pollutants that land on it, including petrol fumes, smog, diesel smoke, exhaust gases, industrial smoke, chemical off-gassing or VOCs from car fabric, leather and plastic materials, air toxins, cigarette odor, etc. Whether they are disturbing allergens, toxic diesel exhaust, moldy odor, or even lingering tobacco smell, So2Pure does NOT just simply destroy them but totally decompose their microscopic remnants into harmless gas and water vapor. The whole process of So2Pure photo catalytic decomposition is non-selective and green in nature. Compare to current popular yet unsafe ozone purification, ionic, or HEPA technology, photo catalyst is by far the most effective purification method available for air treatment. So2Pure durable coating requires only ONE single application to keep your car clean and purified at all time. Each application guarantees for a purification effect of up to 1 year. So2Pure is safe, non-toxic, pH neutral, colorless, and odorless, and can be applied to virtually any surface of your car interior such as headliner, seat, ceiling, dashboard, side panels. Allergy sufferers, chemical intolerant person, smokers, or any odor haters will appreciate the benefits So2Pure coating brings.
