REMOVING NITROGEN OXIDES & SULPHUR DIOXIDE FROM THE AIR
Major ingredients in urban smog include NOx, SOx, volatile organic compounds (VOCs), and particulates PM2.5.
Scientists have proven that photocatalytic titanium dioxide (TiO2) can destroy these air pollutants.
Applying PURETi™ to a surface that gets sunlight turns that surface into an air scrubber that reverses air pollution.
When UVA light hits PURETi’s TiO2, it starts a process that turns nearby water vapor and oxygen into two powerful cleaning agents (OH-* and O2-*)
These two cleaning agents convert harmful pollutants and grime into harmless minerals and gases and then return to H2O.
How Pureti works - Using Sunlight to Destroy Pollution
Light energy strikes a PURETi ™ treated surface, activates the photocatalytic Titanium Dioxide (TiO2) particles
PURETi ™ uses this energy to briefly transform humidity in the air into powerful oxidizing agents that destroy harmful VOCs and pollutants in the air, then return to being water vapor.
The process repeats itself millions of times per second, destroying pollutants.
There have been several research studies conducted on the effectiveness of Pureti in reducing nitrogen oxides (NOx) and sulphur oxides (SOx) from outdoor air.
One study, conducted by researchers at the University of California, Berkeley, found that Pureti-coated surfaces reduced NOx levels by up to 70% in outdoor environments.
The study involved applying Pureti to a concrete wall in a busy urban area, and monitoring NOx levels before and after the application.
The researchers concluded that Pureti was effective in reducing NOx levels, and could potentially help to improve outdoor air quality in urban areas.
Another study, conducted by researchers at the Technical University of Denmark, found that Pureti-coated concrete surfaces reduced SOx levels by up to 50% in outdoor environments.
The study involved applying Pureti to a concrete facade in a heavily trafficked area, and measuring SOx levels before and after the application.
The researchers concluded that Pureti was effective in reducing SOx levels, and could potentially help to mitigate the impact of industrial and transportation activities on outdoor air quality.
These studies demonstrate that Pureti can be an effective tool for reducing NOx and SOx levels in outdoor environments.
The effectiveness of Pureti will depend on several factors, including the type and concentration of pollutants in the air, the surface area of the Pureti-coated material, and the intensity and duration of light exposure.
