Lennox Carbon Coated X6672 MERV 16 Filter 2 Pack - Superior Odor

In this review the Lennox Carbon Coated X6672 Healthy Climate MERV 16 Filter (2 Pack) is examined for homeowners and anyone with a forced-air system who wants near-HEPA level particle removal plus odor control. The bottom line: this genuine Lennox OEM filter is best for people who need high-efficiency filtration and reduced smells without installing a whole-house HEPA system, because its MERV 16 media and carbon coated fiber matrix remove very small particulates while helping control household odors.

Key Features

• Actual dimensions: The filter is sold for a nominal 16 in x 25 in x 5 in slot but measures 15.65 in x 24.65 in x 4.31 in, ensuring a precise fit in compatible air cleaners.
• Genuine OEM: Being a genuine Lennox part provides confidence in build quality and compatibility with Lennox air cleaner models like HCC16-28.
• MERV 16 filtration: The high-efficiency media captures very fine particulates, helping protect HVAC equipment and improve indoor air quality.
• Carbon coated media: The dark gray carbon coated fiber matrix reduces common household odors in addition to trapping particles.
• Cross-brand compatibility: Designed to be a suitable replacement in a number of Honeywell, Carrier, and Trion systems, making it useful for different installations.
• Long service life: Customers report changing these only twice a year, indicating good longevity when used in normal residential settings.

Who It's For

This filter is aimed at homeowners, allergy sufferers, and anyone who wants high-efficiency particulate removal without the cost and complexity of a standalone HEPA system; its carbon coated media is specifically useful in homes with cooking, pet, or mild smoke odors. It also suits owners of Lennox HCC16-28 air cleaners and technicians replacing media in compatible Honeywell, Carrier, or Trion units.

It is less appropriate for systems that cannot accept a thicker media or for buyers who require true HEPA certification for medical-grade needs; likewise, if a household changes filters monthly for heavy contamination, a less expensive, lower-MERV option may be more practical.

Pros & Cons

Pros

Cons
