Lennox X6675 Filter

Upgrade your client's indoor air quality with the Lennox X6675 Carbon Clean 16 Filter, a 20x25x5 MERV 16 high-efficiency media solution. This OEM replacement, also identified as Lennox X667501 or model HCF20-16, provides hospital-grade filtration by capturing over 95% of sub-micron particles down to 0.3 microns and 90% of ultra-fine particles down to 0.1 microns. Designed for a precision fit in the Lennox HCC20-28 housing, its 19-3/4" x 24-3/4" x 4-3/8" actual dimensions also ensure compatibility with select Honeywell, Carrier, and Trion Air Bear air cleaners. The electrostatic media is integrated with a carbon-coated fiber matrix, which actively reduces ground-level ozone and neutralizes volatile organic compounds (VOCs) and odors without increasing system pressure drop. For professional contractors, this Healthy Climate filter is the standard for protecting HVAC components from dust accumulation while maintaining optimal airflow for maximum equipment longevity.

Key Benefits

• MERV 16 Efficiency: Provides the highest level of residential filtration, effectively removing virus carriers, bacteria, and allergens.
• Carbon Filtration: The coconut-activated carbon layer reduces odors from cooking, pets, and smoke.
• Equipment Protection: High dust-holding capacity prevents bypass and keeps evaporator coils clean, maintaining system SEER ratings.
• Universal Compatibility: Serves as a direct replacement for X667501 and fits various 20x25x5 cabinet brands.
• Ozone Reduction: Capable of reducing indoor ozone levels by up to 50% on the first pass.

Common Questions

Is the Lennox X6675 interchangeable with the X667501?
Yes, these are identical parts. The X667501 is simply the full 10-digit manufacturing number for the standard X6675 filter.

Will this filter fit my non-Lennox air cleaner?
If your cabinet accepts a 20x25x5 nominal size and matches the 19-3/4" x 24-3/4" x 4-3/8" actual size, this filter will likely function. It is a common upgrade for Honeywell F100 and Carrier EZXCAB systems.

How often should a MERV 16 filter be replaced?
Under standard operating conditions, these cartridges are designed for 6 to 12 months of service. High-occupancy homes or those with heavy pet dander may require more frequent changes to prevent static pressure issues.
