Airocide uses PCO (Photocatalytic Oxidation)Technology.
PCO purifiers are filterless. They use broad-spectrum UV light in a reaction chamber to cause a reaction with water moisture and a thin sheet of a metal catalyst of titanium dioxide that creates super-oxides and hydroxyl radicals that eradicate air contaminants.
In this reaction, PCO air purifiers destroy air pollutants that get exposed and absorbed on the surface of the thin metal catalyst film of the air purifier’s reaction chamber.
PCO air purifiers are also low maintenance, and you only need to replace your reaction chamber about every 2-3 years.
Photocatalysis as an eco-friendly method of air cleaning
Photocatalytic air purification mimicking the self-cleaning process of the atmosphere.
It’s proposed as an ideal technology for air purification because it can degrade diverse air pollutants into non-toxic or less harmful forms using light under ambient conditions.
PCO process has some similarity to the self-cleaning mechanism in Earth’s atmosphere in that both are based on indirect photooxidation to generate air.
Advantages of photocatalytic air purifiers
- In contrast to classic purification techniques, based on filtration, photocatalytic air purifiers are capable of trapping even the finest gaseous particles (up to 0.001 um).
- Conventional filters consume a lot of power to push the air through a fine-mesh filter. In case of a photocatalytic air purifier this is not required, due to which power consumption is substantially reduced.
- Low power fan has low noise level.
- It eliminates high maintenance costs since the UV lamp replacement is needed only once in three years.
Do PCO air purifiers work?
Using photocatalytic oxidation technology is a safe and effective way to improve indoor air quality. Many air purification systems produce harmful ozone; however, Airocide air purifiers convert ozone into safe, healthy oxygen.
Are photocatalytic air purifiers safe?
PCO air purifiers are standalone portable units that are effective in destroying pollutants. Ozone gas irritates the lungs and results in chronic respiratory diseases. Air purifiers using photocatalytic technology do not release ozone into the indoor environment.
Overall, the most suitable application of photocatalytic air purification is indoor air, where pollutants are at the sub-ppm level and interfering substances such as dust and aerosols can be controlled at a minimal level. The ideal scenario for photocatalytic indoor air cleaning is to utilize ambient room light.
