Perfect Fit for My 2025 GMC Sierra AT4 — Cleaner Air, Easy Install
I installed this PureFlow HEPA cabin air filter in my 2025 GMC Sierra AT4 6 months ago, and it fit perfectly with zero hassle. Swapped it in behind the glove box in under 5 minutes. No cutting, no forcing, no confusion — exactly what you want with filters.I chose this one because I care about air quality, especially with my dog riding with me a lot. The HEPA and activated carbon layers are a big upgrade over the stock filter. I’ve noticed reduced smells and less dust buildup in the cabin over the past few weeks.Airflow is still strong through the vents — no restriction or weird noises. If you’re looking for a serious filtration upgrade for a Sierra or Silverado, this is the one to get. Great value for the money.

Fits 22' Escalade perfectly, No issues.
Installed this in my 2022 Escalade and it fit like a glove. Took just a couple minutes to swap out the old one. I can’t say if it performs better than the OEM filter, but it definitely doesn’t perform worse, which is good enough for me, especially at this price.The air smells clean, no weird odors, and there’s been no drop in airflow or weird noises. It does its job and gives me peace of mind knowing I’ve got a fresh HEPA filter in there. If you're looking for an easy, affordable replacement, this one checks all the boxes.

Nice Filter
The quality appears to be very good and is comparable to other cabin filters I've used. The price is reasonable.

Nice replacement
Good quality and thicker, compared to oem. Fit perfectly on my 24 Colorado. So easy to put in it only took a couple of mins if that.

Want clean air in your vehicle? Buy a Pure Flow cabin filter
Bought this because my father has really bad allergies. It was installed in his 2020 Cadillac XT6 and fit like a glove. It does slow down the velocity of the air coming out of the vents. This is to be expected with any filters installed. Even with the slower air flow I know the air from outside and inside (when on recirculate) is clean fresh air. He doesn't cough as much when he is in his Caddy.

Recently received laced cabin air filter behind glove boxe and noticed big increase in air flow. Easy install & fit snugly.
