The triad photocatalytic oxidation cell, also known as the PCO cell, is highly valued in the market. It is a specialized air purification system that uses light and catalysts to purify the air. This air purifier is easy to use, with periodic cleaning and occasional replacement.
Understanding the right kind of cell is important because it helps you understand the performance your air purifier delivers. Service life and maintenance requirements are important factors that should not be ignored, as they can otherwise cause early replacement.
Triad Aer Photocatalytic Oxidation Cell
6 inches
PCO replacement cell
Up to 9,000 operating hours
Every 30 days
Compressed air or a small vacuum attachment
No—do not clean the PCO cell with liquid
Confirm your exact model and part before ordering
In the past, HEPA filters were used to filter air pollutants mechanically. In this method, air pollutants were captured in the filter and had to be removed manually. In contrast, photocatalytic oxidation is a modern process that uses light to activate a catalyst. This activation triggers a chemical reaction that oxidizes the pollutants. In simple terms, the pollutants are captured and may even be destroyed.
It is often assumed that a photocatalytic cell is responsible for complete odor and contamination removal. This is not always the case. Depending on the cell’s design, it can reduce odor and treat and disinfect the room, but it cannot guarantee 100% removal.
A PCO system’s performance can depend on the device’s design, exposure time, catalyst, and light output. Because of these factors, the reaction may still produce unwanted byproducts that can hinder performance.
While the Triad Aer Photocatalytic Oxidation Cell is designed for Triad Aer V3, there are other air purifiers with which it is compatible, as shown below:
Triad Aer V 2.0
Triad Aer V3
EcoQuest Fresh Air 2.0
EcoQuest Fresh Air 2.1
GreenTech Environmental GT3000
Puratron
Mercola Pure & Clear
Before purchasing a cell for your air purification system, check the model and the cell specification requirements.
The upper-end life of the air purifier cell is listed as 9,000 operating hours. However, this is not exact. It may vary and can even be lower. Let’s calculate an approximation below:
375 days—about 12.3 months
750 days—about 24.6 months
1,125 days—about 37 months
This is an estimate; check the product description and specifications before you buy.
For the Triad Aer v3, the owner’s manual says to replace it when the “Replace PCO Cell” message appears.
If the glowing light disappears, it may indicate a connection issue. Check the manual for troubleshooting instructions or contact your supplier for help. It is best to get a replacement assessment to check the damage and replace it before it causes more problems.
While the glowing light shows the machine is working for basic operations, it does not mean it is fully removing pollutants. Similarly, it does not indicate the product’s remaining useful life. It is also recommended to avoid looking directly into the UV lamp and to operate it only when it is assembled for inspection
Use dry cleaning only. Do not wash, soak, or spray the cell.
According to the basic recommendation, you have to dry clean it. Do not wash, soak, or spray the cell. This is important because dust can accumulate within the compressed air system and the vacuum attachment, so avoid liquid cleaning of the PCO cell. However, if you have washable filters or a purification plate, then you can clean them according to the given instructions
General cleaning reduces the chance of replacement.
Use the complete instructions for your exact purifier. The basic procedure for the V3 is:
Switching off and disconnecting power.
Using the cell in the prescribed disassembly process.
Unplug the electrical plug and remove the retaining nuts.
Fit the appropriate replacement and ensure it is firmly connected.
Reassemble all components and covers before reassembly.
According to the V3 manual, the PCO replacement reminder will be reset automatically after replacement. If it continues to display, seek help.
It is intended to give a general idea of the assembly instructions in this illustration, which are not intended to replace the actual assembly instructions.
No. They differ significantly in maintenance requirements and function.
If you need to replace a PCR cell, focus on getting a PCR cell. If you want to change the filter, a particle replacement filter is preferred. If you want to replace the purification plate, it is recommended to purchase a replacement plate.
According to the EPA, ozone-generating air purifiers are condemned in occupied spaces. Check the air purifier’s manual emission documents to confirm whether it emits ozone. While the product description does not mention ozone production, it may be an advertising claim and can vary by operating mode.
No. Dry cleaning is required for the PCO cell. V3 maintenance instructions do not allow water or other liquids.
The listed cleaning interval is: No. 30 days. Replacement is required separately, depending on service life, operating conditions and the purifier’s instructions.
Such a result cannot be guaranteed. Persistent odors need to be traced. A replacement component does not solve a leak, moisture or a continuous pollutant source.
No. Do NOT consider air cleaning part of indoor air management. EPA’s goal is to minimize pollution sources, ventilate with clean outdoor air, and filter as needed.
We only recommend genuine triad aer parts for optimal performance of until. Also, make sure the part is compatible with your model.
Switch off and unplug the power before inspection—refer to the manual. If it still doesn’t, call support and don’t keep buying replacement cells.
Don’t assume that it does. Check with the seller about what is included in the package (mounting hardware or reused).
Have your purifier model number, past part information, and any maintenance messages ready. Check compatibility and package contents, and install and clean according to instructions.
Order the matching Triad Aer PCO replacement cell, or call support to confirm the part your purifier needs.
