Lennox X8348 Maintenance Kit

When servicing a Lennox PCO-20C PureAir Air Purification System, using the correct Lennox X8348 Maintenance Kit is critical for maintaining systemic integrity and air quality standards. This comprehensive OEM replacement kit—also identified as Lennox X834801—contains the core components required to sustain the photocatalytic oxidation process. The kit includes one MERV 10 pleated filter (nominal 21x26x4), one titanium dioxide coated catalyst insert, and six UV-A lamps. These lamps provide the necessary ultraviolet energy to activate the catalyst, neutralizing volatile organic compounds (VOCs) and odors without producing harmful ozone. For contractors managing Healthy Climate PureAir systems, replacing the X6667 filter annually and the lamps/insert every 24 months ensures the equipment operates at its 2000 CFM design capacity. Professional tip: avoid washing the metal mesh insert, as moisture will strip the catalytic coating and compromise the system's ability to oxidize airborne contaminants effectively.

• Complete System Refresh: Includes the X6667 MERV 10 filter, 75X66 catalyst insert, and six X8149 UV-A lamps for a full technical overhaul.
• High-Efficiency Filtration: The pleated media effectively captures bioaerosols and particles as small as 0.3 microns, protecting downstream HVAC components.
• VOC and Odor Control: The PCO metal insert works with UV light to break down chemical vapors and household odors at a molecular level.
• OEM Compatibility: Precision-engineered for a drop-in fit in the Lennox PCO-20C housing, eliminating airflow bypass issues common with third-party filters.

What is the difference between Lennox X8348 and X834801?
They are technically identical. Part number X834801 is the specific SKU used for individual retail units, while X8348 is the general series designation. Both fit the PCO-20C air purifier.

How often should the UV lamps and catalyst insert be replaced?
While the MERV 10 filter is typically an annual replacement, the six UV-A lamps and the metal catalyst insert should be replaced every 24 months to maintain effective photocatalytic oxidation.

Can I wash the metal catalyst insert to save on replacement costs?
No. The insert is coated with a specific titanium dioxide catalyst. Washing it will destroy this coating, rendering the PureAir system's odor-removal capabilities useless.
