How PCO (Photocatalytic Oxidation) Works in Air Purifiers:

You've probably heard of ultraviolet (UV) light before. The sun produces UV light and we use products such as sunglasses and sunblock lotion to protect ourselves from prolonged exposure to UV light, avoiding the possibility of harmful effects. What you may not know is that ultraviolet light can come from sources other than the sun and that we can benefit from the power of UV light. One such example is an air purifier equipped with Photocatalytic Oxidation (PCO) technology.

In many homes, harmful airborne elements such as dust, pollen, pet dander, tobacco smoke and mold spores float around in the air, triggering asthma or allergy attacks and simply affecting our ability to breathe. Air purifiers with PCO technology are designed as solutions to this common threat of poor indoor air quality. They are equipped with photocatalytic chambers, essentially where all the magic happens. Inside of these chambers are ultraviolet (UV) bulbs and a small amount of titanium dioxide (TiO2). When the UV light is exposed to the titanium dioxide, highly reactive electrons are formed: hydroxyl radicals and super-oxide ions. These highly reactive electrons are the power behind the air purification.

Once the air purifier is in operation, airborne elements and volatile organic compounds (VOCs) which can often come from building materials and personal/home care products are sucked into the air purifier, right into the photocatalytic chamber. These airborne elements and VOCs are chemical compounds, which are sometimes made up of dangerous combinations of elements. Naturally, the highly reactive electrons will immediately latch onto these compounds that enter the chamber and start breaking them down. In a process known as oxidation, the harmful compounds are broken down into harmless compounds such as water (H20) and carbon dioxide (CO2), thus purifying the air of your room in this repeated process.

Therefore, UV light is the backbone of this technology. Not to be confused with air purifiers that use UV air purification, which you could guess also uses UV light, PCO air purifiers employ UV lamps with additional wavelengths along with titanium dioxide (TiO2). With more wavelengths come quicker reactions. Studies have shown that this technology is extremely efficient, with the ability to rid your air of the common airborne particles as well as viruses, toxic gases and chemicals. Going back to the well-known fact that prolonged exposure to UV light can be harmful, the air purifiers that use this technology ensure no leakage, meaning PCO air purifiers are safe to use and very effective at their intended use.
