Frequently asked questions

What vehicles does the ACDelco CF177 fit?▾

The CF177 (GM part 20901295) fits select Chevrolet, GMC, Hyundai, Kia, and Saturn models. Community-confirmed fits include Chevy Equinox 2010, 2013, and 2015; GMC Terrain 2013; Hyundai Sonata 2013; and Hyundai Santa Fe XL 2016. The outer dimensions are 13.5" × 10.5" × 0.9". Always verify fitment against the Amazon fitment lookup or ACDelco's catalog for your specific year, trim, and engine variant before ordering.

Does the ACDelco CF177 have an activated carbon odor layer?▾

'Odor Reduction' appears under Common Applications in the product spec table, but no activated carbon layer is explicitly mentioned in any feature bullet or product description. The multi-layer non-woven compound media may capture some odor-bearing particles (pollen, dust, mold spores), but this is not the same as a dedicated activated carbon adsorption layer. If activated carbon odor filtration is a priority, look for a filter that explicitly confirms an activated carbon layer in the product description.

Which direction does the ACDelco CF177 install · is there an airflow arrow?▾

No directional arrow is printed on the CF177. Community owners confirm the filter and the OEM filter it replaces both lack a directional arrow. Follow your vehicle's cabin filter housing orientation or a YouTube installation video for your specific make and model to ensure correct placement.

Why does the ACDelco CF177 carry a Prop 65 warning?▾

The product listing shows a California Prop 65 warning, which is unusual for a standard non-woven fiber OEM replacement filter. The specific trigger substance is not identified in the product listing. The warning may relate to trace manufacturing chemicals (binders, fiber-bonding agents) or cardboard adhesives · not the filter media during normal use. Normal installation and operation are unlikely to create meaningful consumer exposure.

CarCareTruth's Analysis

Last reviewed June 4, 2026

TL;DR OEM-precision fit for Chevy Equinox (2010·2015), GMC Terrain, Hyundai Sonata, and Hyundai Santa Fe XL · community owners confirm correct housing seating across these platforms. Multi-layer non-woven synthetic media rated OEM-equivalent; odor reduction is listed but activated carbon layer is unconfirmed; no named test certification; standard 12-month replacement cadence.

What it is and how it performs

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 the product 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 for covered vehicles. Owners note the 45-pleat design improves airflow over lower-pleat alternatives. Standard 12-month or 12,000-mile replacement cadence per OEM category norms.

Who should buy this · and who should skip it

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 owners confirm installation without bypass gaps. Skip 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 filter with a named efficiency certification provides verified submicron filtration at a comparable price point.

Safety and environmental impact

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 product listing; the trigger substance is not identified in available product data, and normal installation does not create meaningful consumer exposure. The probable cardboard frame component is recyclable if separated from the synthetic media at end of service; the synthetic non-woven media is landfill-bound at the standard 12-month replacement interval.

Find the cabin filter for your car

A cabin filter only does its job if it actually fits your car, and the same vehicle often takes a different part year to year. Before you buy, find the cabin air filter for your vehicle in the CarCareTruth cabin-filter finder · pick your year, make, and model and we'll show the filters that fit it, ranked by our independent score and cross-checked against multiple catalog fitment sources.
