What to know before buying

Listing details to confirm

The listing uses nominal 20 × 25 × 5 sizing but gives actual dimensions of 19.8"L x 24.8"W x 4.3"Th. Confirm those measurements and compatibility with your system before ordering. The feature text claims a two-filter pack, while the details list Number of Items as 2 and Unit Count as 1 Count, so the package quantity is not fully clear. MERV 16 particle-capture performance and the suggested replacement intervals are manufacturer claims, not independently verified guidance.

Who is it for?

A good fit for

Owners of a compatible Lennox X6675 or HCC20-28 system who can confirm the listed actual dimensions fit their filter slot.
Buyers seeking a listed MERV 16 replacement and willing to verify package quantity and system fit before purchasing.

Aggregate ratings lean positive, with many five-star ratings, but a smaller one-star share means the overall figure does not show why some buyers were dissatisfied. With a limited rating sample and no written feedback supplied, the ratings cannot establish specific fit, filtration, or durability experiences. For this filter, checking the actual dimensions and uncertain pack quantity remains important.
