X6672 16x25x5 MERV 16 Carbon Clean Furnace Filter - 2 Pack

In this review of the X6672 16x25x5 MERV 16 carbon clean furnace filter, the bottom line is simple: it is for homeowners and facility managers who need very high efficiency filtration for HVAC systems compatible with Lennox, Honeywell, Carrier and Trion models. The reviewer found the standout reason to buy is its MERV 16 high efficiency filtration using coconut-activated carbon coated fibers that capture ultrafine particles down to 0.1 microns, which noticeably improved indoor air clarity and reduced odors in living spaces.

Key Features

• Compatibility: Fits Lennox X6672 and HCC16-28 and several Honeywell, Carrier, and Trion Air Bear models so it can replace common OEM parts without modification.
• MERV 16 filtration: The dense media removes very fine particles, helping reduce airborne allergens and ultrafine contaminants for cleaner indoor air.
• Carbon coated fibers: Coconut-activated carbon in the matrix helps reduce odors and VOCs, making rooms smell fresher after installation.
• Long service life: The filter is built for durability and can last up to 1 year under typical conditions, lowering replacement frequency.
• Easy installation: No tools are required and the filter drops into standard housings with a snug fit based on the stated 24.65 in x 15.75 in x 4.33 in actual dimensions.
• Two-pack value: The package includes two replacement filters, which is convenient for staggered replacement schedules or multiple systems.

Who It's For

The X6672 MERV 16 filter is best for homeowners with allergy or odor concerns, small clinics, or anyone running a residential HVAC system that lists Lennox X6672, Honeywell F25A1043-type, Carrier EZXCAB016-type, or Trion Air Bear Supreme replacements. Its high capture rate for very small particles makes it useful where air quality matters most.

Users seeking a low-restriction, low-cost basic filter should look elsewhere; this is a high-efficiency, denser filter that prioritizes particle capture and odor control over minimal airflow resistance. Also, those with unique or proprietary filter housings should verify fit against the stated dimensions before buying.

Pros & Cons
