Good fit for our Honda Accord, quality filter
This was the perfect fit for my daughter's Honda Accord. It's a solid, budget‑friendly upgrade that fits perfectly. It only took a few minutes to install. The pleated material feels sturdy, and the activated carbon layer helps cut down on odors and everyday cabin dust.

No more funky smell!
Have had a funky smell for a while in my car. Air fresheners just couldn't quite cover it up.
I pulled the old filter out which was reallll caked up with stuff and got the new one in. Not only is the funky smell finally gone, but the HVAC is a lot quieter when on full blast, and it blows the air harder.
It fit great, installation was easy, and having the smell gone makes it worth absolutely every penny.

Good and Cheap
Works great on my 1997 Honda Accord EX 2.2L. Great value for the money. Installed it myself. Only a 30 day warranty though.
