Lennox X6670 Replacement Filter

The Lennox X6670 is a high-performance MERV 11 replacement filter engineered for the Healthy Climate HCF16-11 and HCF16-10 series. As a veteran-grade OEM component, this pleated media filter is essential for contractors maintaining HCC16-28 air cleaner cabinets. It effectively captures 85% of airborne particles down to 3 microns, including VOCs, bioaerosols, and common allergens, without significantly increasing static pressure across the heat exchanger. Supported by a robust moisture-resistant frame, the 16x25x5 air filter handles up to 1600 CFM of airflow, ensuring your client's blower motor operates within designed parameters. The Lennox 16x25x5 nominal housing requires a precise actual fit of 15 3/4" x 24 3/4" x 4 3/8" to prevent air bypass. This genuine Healthy Climate filter (also cross-referenced as X667001) provides a superior alternative to standard 1-inch filters, utilizing deep-pleat technology to extend service life and protect evaporator coils from debris accumulation.

Key Benefits

• Precise OEM Fit: Ensures a seamless seal in HCC16-28 and HCF16-11 housings, preventing unfiltered air bypass.
• Advanced Contaminant Control: The MERV 11 synthetic media traps up to 85% of particles as small as 3 microns.
• Multi-Brand Compatibility: Directly replaces and fits specialized 16x25x5 cabinets from Honeywell, Carrier, and Bryant.
• System Protection: Reduces dust buildup on cooling coils and internal components, maintaining thermal efficiency.

Common Questions

Is the Lennox X6670 interchangeable with the X667001?
Yes, these are technically identical part numbers. The X6670 is the standard catalog identifier for the HCF16-11 media, ensuring full compatibility with your existing Healthy Climate cabinet.

How does this MERV 11 filter impact system static pressure?
Unlike restrictive 1-inch high-MERV filters, the 5-inch deep-pleat design of the X6670 provides more surface area, allowing for high-efficiency filtration with a minimal pressure drop, which protects the longevity of the blower motor.

Can I upgrade from this filter to a higher MERV rating?
Yes, for environments requiring superior filtration, the Lennox X6672 (MERV 16) is the direct high-efficiency upgrade that fits the same 16x25x5 cabinet footprint.
