A PCO (Photocatalytic Oxidation) air purifier is a type of air purification technology that uses UV light to activate a catalyst, typically titanium dioxide (TiO2), to break down and oxidize pollutants and contaminants in the air. This process creates a chemical reaction that converts pollutants into harmless carbon dioxide and water molecules, leaving the air clean and fresh.
How Does a PCO Air Purifier Work?
The working principle of a PCO air purifier is based on the photocatalytic reaction. Here's a step-by-step explanation of the process:
1. The air purifier draws in contaminated air, which passes through a pre-filter to remove larger particles and debris.
2. The air then passes over a UV light source, typically a low-wattage LED or fluorescent lamp, which emits UV radiation.
3. The UV radiation activates the photocatalyst, usually titanium dioxide, which is coated on a surface or embedded in a filter.
4. The activated photocatalyst reacts with the pollutants in the air, such as volatile organic compounds (VOCs), bacteria, viruses, and other microorganisms, to break them down into smaller molecules.
5. The broken-down pollutants are then oxidized, converting them into harmless carbon dioxide and water molecules.
6. The clean air is then released back into the environment, free from pollutants and contaminants.
Benefits of PCO Air Purifiers
PCO air purifiers offer several benefits over traditional air purification technologies:
1. Effective against a wide range of pollutants: PCO air purifiers can remove a broad spectrum of pollutants, including VOCs, bacteria, viruses, mold, and fungi.
2. Low maintenance: PCO air purifiers typically require minimal maintenance, as the photocatalyst is self-cleaning and doesn't need to be replaced.
3. Energy-efficient: PCO air purifiers are often energy-efficient, using low-wattage UV lamps and requiring less power than traditional air purifiers.
4. No byproducts or residues: PCO air purifiers don't produce any byproducts or residues, making them a safe and eco-friendly option.
5. Silent operation: PCO air purifiers are often silent or very quiet, making them suitable for use in homes, offices, and other noise-sensitive environments.

4. UV-PCO air purifiers: These air purifiers combine UV light with PCO technology to provide enhanced air purification capabilities.
Key Features to Consider When Buying a PCO Air Purifier
When shopping for a PCO air purifier, consider the following key features:
1. UV light wavelength and intensity: Look for air purifiers with UV lights that emit a wavelength of 254-265nm, which is most effective for activating the photocatalyst.
2. Photocatalyst quality and quantity: Ensure the air purifier uses high-quality titanium dioxide or other photocatalysts and has a sufficient amount to provide effective air purification.
3. Airflow and CADR: Consider the air purifier's airflow rate and clean air delivery rate (CADR) to ensure it can handle the size of your space.
4. Filter type and replacement: Check if the air purifier has a pre-filter or other filters that need to be replaced, and how often they need to be replaced.
5. Noise level and operation: Consider the air purifier's noise level and operation, especially if you plan to use it in a bedroom or living room.
