Good Quality Replacement for Lexus
Style: BE-285 1-Pack
Was a perfect fit for my 2016 Lexus NX200t. No tools required. Total of 5 minutes to install. Airflow is good after replacement and the activated charcoal seems to make a difference in reducing any smells from outside. Recommended.

Economical, easy to install, and does the job!
Style: BE-182 1-Pack
First, depending on your car model, replacing your cabin air filter is VERY easy.
With that out of the way, the shop wanted to charge almost 65 dollars to replace my cabin air filter. Decided to just buy one and do it myself. The only downside of waiting is that the air inside the car is not as fresh/clean when you're running your air. Anyways, you can usually get these kinds of filters between 20-45 dollars from auto part shops depending on the brand and features. I've used this brand and filter for the past 3 replacements on my car and they last just as long and filter just as well from my experience. No issues installing, and does in fact do a good job of filtering outside odors.
Highly recommended for the price!

Fits my 2026 civic sport perfect!
Size: AF151
No issues, fitment is perfect. Great quality for an excellent price. Dealer wanted like $24 for a basic one. Nah I'm good I'll just go on Amazon and get it for $8. Took 30 seconds from start to finish can't get any easier.

Fits well and installs easily.
Size: AF997
This filter looked about the same as the OEM filter. It installed in about a minute. The quality appeared to be fine. It was protected in a cardboard box. It fit my 2014 Subaru Outback perfectly. I just installed it an hour ago so I don’t have any long term observations about longevity or effectiveness. I can’t see any reason why it would not work as well as the original, it seemed identical.
