Lennox X6672 Replacement Filter

The Lennox X6672, also identified by the manufacturing part number X667201, is the primary MERV 16 replacement filter for the Healthy Climate HCC16-28 air cleaner. This 16x25x5 furnace filter utilizes a pleated electrostatic filter media engineered to maintain a 1600 CFM air flow rate with an initial resistance of approximately 0.25" w.g. The HCF16-16 design features a carbon-coated fiber matrix, providing a laboratory-grade solution that reduces ozone concentrations and neutralizes volatile organic compounds (VOCs). With an actual size of 15-3/4" x 24-3/4" x 4-3/8", this high-efficiency air filter captures over 95% of sub-micron particles down to 0.3 microns and 90% of bioaerosols as small as 0.1 microns. It is a critical component for maintaining system static pressure while achieving hospital-level air filtration in residential and commercial HVAC systems.

Key Benefits for Contractors:

• Broad Compatibility: Direct Lennox X6672 replacement filter for HCC16-28 cabinets; also serves as a high-performance upgrade for Honeywell F100, Carrier EZXCAB, and Trion Air Bear 16x25x5 housings.
• Industrial-Grade Filtration: The MERV 16 rating ensures the capture of bacteria, viruses, smoke, and fine dust, protecting the evaporator coil from fouling and maintaining system efficiency.
• Low Pressure Drop: Designed with Precision Pleat™ technology to maximize surface area, ensuring the 1600 CFM air flow is not compromised even at high filtration levels.
• Odor & Ozone Mitigation: The integrated carbon clean technology reduces ground-level ozone by up to 50% and adsorbs persistent household odors.
• Simplified Maintenance: The X667201 is a fully assembled box filter that slides into place without the need for additional combs or assembly, reducing on-site labor time.

Common Technical Questions:

Is the Lennox X6672 interchangeable with the X6670?
Yes, the Lennox X6672 shares the same actual size (15-3/4" x 24-3/4" x 4-3/8") as the X6670. It is a direct MERV 16 upgrade for systems currently utilizing the MERV 11 X6670 or MERV 13 19L16 (HCF13-16) filters.

What air cleaners fit a 16x25x5 Lennox filter?
This media is specifically designed for the Healthy Climate HCC16-28 cabinet but is technically compatible with any high-velocity housing that accepts 5-inch deep media, including the Honeywell F200E and Carrier MPKA series.

How does this filter affect HVAC system static pressure?
While MERV 16 filters are high-density, the X6672 is engineered for 1600 CFM performance. Technicians should verify total external static pressure (TESP) during installation to ensure the system operating point remains within the blower's specified curve.
