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.
