What is UV PCO?
UVCatalyst™ uses activated carbon plus the natural power of UV light and an advanced photocatalytic oxidation (PCO) process to disinfect circulating HVAC air while capturing and breaking down molecules of toxic VOCs, common household odors, and pathogens / allergens.
Are PCO air purifiers safe?
PCO Gases catalysts are ineffective in destroying gaseous pollutants from indoor air. Ozone Particles, gases, sold as air cleaners, they are not always safe and effective in generators biologicals removing pollutants. By design they produce ozone, a lung irritant.
What is a PCO in HVAC?
The PureAir and PureAir S systems reduce concentrations of pollutants through a process called photocatalytic oxidation (PCO). Similar to the process used by the Department of Defense to combat germ warfare, PCO combines nature’s three most powerful air purifiers: Ultraviolet light.
What is PCO technology?
Photocatalytic Oxidation (PCO) is a very powerful air purification technology and has the ability to destroy particles as small as 0.001 microns (nanometer) whereas HEPA filters can only filter particles as small as 0.3 microns.
What do you mean by photocatalyst?
The term photocatalyst is a combination of two words: photo related to photon and catalyst, which is a substance altering the reaction rate in its presence. Therefore, photocatalysts are materials that change the rate of a chemical reaction on exposure to light. This phenomenon is known as photocatalysis.
Are UVC air purifiers effective?
UV air purifiers are designed to use short-wave ultraviolet light (UV-C light) to inactivate airborne pathogens and microorganisms like mold, bacteria and viruses. In fact, the EPA says that a UV-C air purifier does not seem effective as a stand-alone unit because it cannot trap or remove particles.
Does PCO produce ozone?
PCO does not emit harmful substances that might harm the ozone layer nor does it produce ozone. The photocatalytic technology is also effective in eliminating airborne triggers for allergies and asthma from ozone.
What is a photocatalyst filter?
A photocatalytic air purifier is a specialized air filtration device using advanced technology. Air Oasis is proud to be among the first in the industry to bring you this bold new innovation, which is based on research from NASA and has been developed as a compact, efficient filter for residential and commercial use.
Does UV light purify air?
UV lights do improve air quality because they are a sanitation device. A UV light can inactivate biological aerosols that affect indoor air quality, including mold, mildew, fungus, bacteria, and viruses. Therefore, having an ultraviolet light mode on an air purifier can improve the air purification quality of the unit.
What is UV photocatalyst?
Photocatalysts are defined as materials which decompose detrimental substances under the sun lights containing UV rays. Pairs of electron and hole are excited by UV lights. The photo-generated electrons produce anion radicals like by reacting with O2. The holes produce active OH radicals by reacting with water.
Does UV-PCO really purify the air?
Ultraviolet photocatalytic oxidation (UV-PCO) has been acclaimed as one of these innovative technologies for purifying indoor air by decomposition of pollutants, especially volatile organic compounds (VOCs). Although numerous studies have been carried out in this field, UVPCO performance under real life applications is still questionable.
How does the uvcatalyst™ PCO module work?
With its high surface area, you can rest assured that the UVCatalyst PCO module is achieving maximum capture of airborne contaminants and household odors. In addition to powering the PCO process for odor reduction, the UVCatalyst™ uses UV light to kill millions of airborne bacteria and viruses (including the flu virus).
How does uvpco perform in real life applications?
Although numerous studies have been carried out in this field, UVPCO performance under real life applications is still questionable. Experimental conditions of most previous works focused on ppm level of VOCs in ideal bench-top-scale reactor with low flow-rate and high residence time conditions.
What is PCO technology and how it works?
The technology works by breaking down the pollutants to improve the quality of air and water. It is regarded to be the best alternative for wet digestion of organic compounds. PCO offers many advantages like minimal secondary pollution, easy operation, less energy consumption, and high efficiency.
