40K+ miles o my 2020 Ranger. Thought I’d replace the CAF (cabin air filter.) Holy c__p. The original factory filter was clogged with dust, mesquite seeds, Palo verde droppings -YUCK. This reusable filter improved airflow immensely, plus the cabin feels fresher. Quite a bargain compared to the major brand reusable CAF (K_N) too, or pulling clogged filters, throwing them in the trash and buying a new disposable filter to install. I’m looking forward to pulling this in a month and seeing what it kept out of my breath, washing it, and reinstalling it.

Great filter

Style: HCC2146-X

My husband said this filter was high-quality, he was quite impressed. We’re not crazy about the washable kind normally, so we’ll have to see how it holds up.
