Same Quality, Cheaper Price!
Fits exactly as it should (2018 Acura RDX) and performs as well as any other brand I've used over the years. Construction and material quality appear as good as (or better) than any other off-the-shelf brand. I have no qualms about using this brand in the future and saving money doing so, compared to other brands.

Worked in RDX 2nd gen
It fit perfect in RDX 2nd gen. The filter built quality looks pretty much like OEM or better. I do not see any performance issue. Price was reasonable. Its a good buy.

DIY!!
Bought this cabin air filter for my 2015 Honda CR-V and it fit perfectly. Installation was super easy and only took a few minutes. I immediately noticed the air coming through the vents smelled cleaner. No need to have it replaced for you. Definitely worth it if you want an affordable replacement that gets the job done.
