PCO Technology in Air Purifiers

Photo catalytic Oxidation

Photocatalytic Oxidation, commonly known as PCO Technology, is a highly acclaimed air quality solution found in portable and HVAC induct air purification systems. This cutting edge technology integrates the power of ultraviolet light rays (UV) with a titanium dioxide catalyst to effectively clean the air around us.

Recent advancements in catalytic materials have made PCO (photo catalytic oxidation) technology more accessible in air purifiers. Despite being around for decades, PCO technology has only recently become widely available. Apart from PCO, also read about needlepoint ionization role in air purification. 

What Is The Functioning Principle Of PCO Technology?

Introducing PCO Technology, a cutting edge solution that effectively eliminates pollutants from the air. By merging UV light with titanium oxide coated materials, we create powerful hydroxyl radicals and superoxides. 

These reactive electrons act like molecular superheroes, swiftly neutralizing volatile organic compounds (VOCs), bacteria, and other airborne contaminants. Experience the transformation as pollutants are broken down into harmless molecules, resulting in fresher and healthier indoor environments.

Discover the power of PCO Technology, the innovative air purification solution that ensures your indoor environment remains safe and free from harmful substances. Unlike other technologies, PCO does not produce ozone or emit any toxins, making it the ideal choice for healthy living. Experience the benefits of clean air with PCO Technology today.

PCO air purifiers utilize light energy to activate a catalytic process that effectively eliminates pollutants and bacteria from the air. By utilizing UV light energy, the photocatalyst triggers a chemical reaction that breaks down pollutants and bacteria within the purifying chamber.

The resulting byproducts may include water and carbon dioxide. It is important to note that while PCO systems provide effective passive air purification, they are only capable of reducing airborne pathogens that come into contact with the system.

PCO technology requires a UV light source to activate the photocatalyst. Typically, high intensity incandescent lamps or LEDs emit UV light that is absorbed by the photocatalyst. This UV light source provides the necessary energy to activate the photocatalyst.

Benefits Of PCO Technology Air Purifiers

Air purifiers that utilize PCO technology provide numerous benefits compared to conventional air purification methods based on mechanical filtration. Some of these advantages include:

  • Efficient in decreasing airborne contaminants.

PCO technology is proven to efficiently eliminate a variety of pollutants and bacteria, such as volatile organic compounds (VOCs), mold, and allergens. This makes it a perfect solution for facilities where occupants are affected by seasonal allergies or respiratory issues.

  • Minimal system maintenance required.

PCO technology offers a hassle-free solution for enhancing indoor air quality. Unlike conventional air purifiers, it doesn’t demand frequent filter replacements. This advantage is particularly beneficial for facilities seeking to improve air quality minus the burden of ongoing maintenance and costly consumables.

  • Operation the system in a quiet manner:

PCO air purifiers are designed to be quiet, making them perfect for offices and learning environments. They operate at low decibel levels, ensuring minimal disruption to the indoor environment. This is especially beneficial for facilities that require effective air quality solutions without the excessive noise pollution.

  • Extended lifespan of technology:

The PCO technology eliminates the need for regular replacement of traditional filtration media. With a lifespan of 12 to 24 months, the photo catalyst used in PCO technology lasts longer compared to traditional air purifiers.

Uses of PCO Technology

PCO technology is highly versatile and is the perfect choice for enhancing indoor air quality in various settings. It finds wide-ranging applications, and some of the most popular ones include:

Commercial Buildings And Offices: 

PCO technology offers an excellent solution for offices by enhancing air quality in spacious workspaces, promoting a healthier and more conducive environment for employees.

Education from K-12 schools to higher education:

PCO technology is perfect for schools as it enhances air quality and diminishes the presence of common airborne pathogens found in learning environments. Moreover, PCO air purifiers with quiet operation are particularly ideal for classrooms where listening is essential for effective teaching and an enhanced student experience.

Hospitals and healthcare facilities play a crucial role in providing medical care.

PCO technology is vital for healthcare facilities, ensuring the health and wellbeing of patients and staff through improved air quality. Its benefits extend to hospitals and medical facilities, where it effectively minimizes the transmission of harmful bacteria and pathogens, safeguarding the medical environment.

Drawbacks of PCO Technology in Air Purification

PCO technology is ideal for people who want a more efficient and cost-effective air filtration system, but it’s not without its drawbacks. One of the biggest concerns with PCO technology is that it’s prone to clogging, which can reduce efficiency and ultimately shorten the lifespan of the filter. 

Additionally, the byproducts created by PCO technology such as ozone and other airborne chemicals may cause health problems in some people. It’s important to do your research before investing in a PCO-based system, and talk to an experienced contractor who can help you make the best decision for your property.


PCO technology UV light applied in air purification systems is an effective way to remove a wide range of pollutants from the air. It works by breaking down pollutants into harmless carbon dioxide and water using UV-C light and a catalyst. 

PCO technology is not without its limitations, but when used in conjunction with other air purification techniques, it can provide excellent results. With the air quality outside becoming more polluted by the day, a reliable air purifier with PCO technology is a smart investment in your health and wellbeing.
