ACDelco GM Original Equipment CF177 Cabin Air Filter

A multi-layer non-woven synthetic compound media OEM replacement cabin air filter (13.5" × 10.5" × 0.9") for select Chevrolet, GMC, Hyundai, Kia, and Saturn platforms. ACDelco's separated-layer construction targets particle capture; "Odor Reduction" appears in Amazon specs but no activated carbon layer is explicitly confirmed. No named test standard (ASHRAE, ISO 16890, EN 1822, or MERV rating) is cited — OEM-equivalent efficiency tier only. GM part number 20901295 ensures dimensional precision. Verified Amazon reviewers note the 45-pleat design improves airflow over lower-pleat alternatives (Amazon review R3ABQPNXIV1XHN). Typical replacement cadence is 12 months or 12,000 miles per OEM category norms.

The right pick for owners of confirmed fitment vehicles — Chevy Equinox, GMC Terrain, Hyundai Sonata, and Hyundai Santa Fe XL — where the OEM part number guarantees dimensional precision and verified Amazon reviewers confirm installation without bypass gaps (reviews R38E3FK5YQQU0R, RIYUAHCPKP5V4, R1F85G9W64JFU4). Skip it if your vehicle is not in the confirmed fitment list — an incorrectly seated filter allows unfiltered air to bypass the media entirely, providing no filtration benefit. Also skip if you need independently certified PM2.5 or allergen filtration efficiency: no ASHRAE, EN 1822, or equivalent test data is available; a HEPA-certified alternative with a published test result provides verified submicron filtration at a comparable price point.

Passive replacement component — multi-layer non-woven synthetic filter with no chemical exposure pathway during normal installation. A Prop 65 warning is present on the Amazon listing; the trigger substance is not identified in available product data, and normal installation does not create meaningful consumer exposure. The cardboard frame component is recyclable if separated from the synthetic media at end of service; the synthetic non-woven media is landfill-bound. At a standard 12-month replacement interval, one spent filter per vehicle per year is the total disposal burden.
