Much Needed Cabin Air Filter Replacement!
This Cabin air filter replacement is working well. It had been a long time since I replaced my cabin filter, so this was a much needed replacement. It was easy to do, and a much needed replacement. The air quality inside my car is much better. It smells fresh, and light and airy now.

Great quality and noticed an immediate difference!
Style: BE-966H 1-Pack
Even though it’s not the OEM (original) filter, the quality is outstanding! It was easy to install and fits perfectly. I noticed a significant improvement in the air quality inside my car right away. Definitely a great buy!

Easiest DIY ever
Style: BE-157H 1-Pack
So a Toyota dealer will want $40+ to replace this filter, but for $10 and 2mins you can easily do this yourself. There’s a great 1:30 how-to vid on the YouTube, drop the glove box (one push) open the little door, remove old filter (note the arrow) and put in the new one, close door, close glove box, enjoy better flow and fresh air. This filter is a HEPA so it’s a performance upgrade over the OEM, fit is perfect, seems sturdier than the OEM, great value if you’ve got 2mins. Highly recommend. Thanks!

Awesome Cabin Air Filter
Style: BE-151H 1-Pack
This product is not only cost efficient, it was also easy to install. The instructions in the package were helpful. I would definitely recommend using this filter for your 2017 Hyundai Sonata.

the "fit" is very precise
Style: BE-176H 1-Pack
Nice Fabrication, Good materials, perfect adhesive applications, "clean joints" etc. Appears to be a good UPGRADE from the stock Motorcraft product. CONs: The FIT was a "smidge TIGHT", and took very precise initial alignment and "pressure" to begin to slide into the rectangular hole. I measured the "Hole" at 7.375" wide, or (187.33 mm)... the FILTER is exactly the SAME. I would suggest maybe reducing the Width by 1 mm, to allow for an easier installation. The MOTORCRAFT uses an "open-cell" foam structure for the (2) Side pieces on their filter assembly, allowing some "compression to fit", of the Width, easing the difficulty of installation, yet still filling all voids. In summation, the "fit" is very precise. Not to be hurried or rushed, maybe a bit meticulous for the impatient or weak of heart.
