EPAuto CPJ6X (KD45-61-J6X) Cabin Air Filter Replacement for Mazda

The EPAuto CPJ6X cabin air filter is a great replacement for my Mazda 3 and made an immediate difference in air quality inside the vehicle. Installation was quick and straightforward—it fit perfectly without any modifications. The activated carbon layer does an excellent job of reducing odors, dust, and general road smells. The cabin air feels noticeably fresher and cleaner, especially when running the A/C or heat. Build quality feels solid for the price, and it works just as well as OEM filters I’ve used in the past, if not better. It’s an affordable maintenance item that really improves driving comfort. If you want a simple, effective upgrade to your vehicle’s air quality, this is definitely a 5-star choice.

This EPAuto cabin air filter was a great replacement for my Mazda. It fit perfectly, was very easy to install, and feels just as well-made as the original filter. The airflow is strong, and I noticed the air inside the car smelled cleaner and fresher after replacing the old filter. For the price, the quality is excellent and it's an easy way to save money compared with having the dealership replace it. I would definitely purchase this filter again and recommend it to other Mazda owners.

I first started using the EPAuto CPJ6X cabin air filter in 2024 for my Mazda CX-5, and I chose the same filter again for this year’s replacement. It fits perfectly, and the installation couldn’t be easier. Since the filter is designed to fit into the slot in only one direction, there’s no need to worry about installing it upside down. The build quality looks very solid. When I first replaced the original filter with this one, I didn’t notice any significant difference—which is actually a good sign, as it performs just as well as the OEM filter. It’s fully compatible with the Mazda CX-5. I’ve also purchased filters from this brand for other vehicles in the past, and they consistently deliver good quality products. I'd recommend this filter for your Mazda.

Fits mazda cx-5. Saves money vs dealership Not too hard to install. Find a video on YouTube. No tools needed just a little squeeze

This filter fits perfectly, it is an exact fit match to the oem one. It has a couple fewer pleats that the oem one, and to my eye appears that it may be slightly thinner material. But at less than half the cost it is a great alternative. So far it seems to be working just as well as the oem filter.

I have a 2019 Mazda CX-5. The cabin air filter fit perfectly. It was simple to install from the videos. I am not a mechanic and without tools took me 10 minutes. Took longer to clear out the glove compartment than replace the air filter. The dealer wanted about $100 to replace this filter. The MFR says to replace the filter yearly. My filter was very dirty and the new filter really helped increase all air flows. All good reviews. Enjoy!

Perfect replacement for my CX5 at a fraction of the price from the dealership.

Easy to install.on cx5 and is exact fit.

Perfect fit for our CX-5 and super easy install!
