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.
