Perfect fit!
Size: 14-22 2.0L hybrid, Size: 14-22 2.0L hybrid
This is a good value for a combo package which includes a cabin air filter as well as the engine air filter. Both filters were a perfect fit in my 2019 Honda Accord hybrid. The cabin air filter airflow direction is clearly labeled and the pleats are sturdy. Installation was super easy- just drop the glove box cover, pop the cabin filter cover plate, pull out the grungy old filter and pop in the new one. Easy peasy. The engine air filter is also a perfect fit. No complaints or concerns here.

The Best Filter Jerry, The Best!
Size: 2" x 10" x 11"
I installed once and it seems to work like a charm. I probably need to go rinse it off since it's been months--but I no longer have Honda telling me I need to replace an air filter when I go get an oil change. They tried but I knew it wasn't mine. LOL. Easy to install, and extremely good quality. No gaps in filter area either.

Perfect fit for my fit
Size: 2" x 10" x 11"
Bought this for my Honda fit sport. Perfect fit for my fit. We shall see how it works out in the long run. I'm guessing every six months I'll wash it out, give it a light piling with the refresher kit I bought. The car doesn't get driven a lot during the year, so, doing it this way should be more than fine.

Premium, Reusable Cabin Filter – Worth It Long-Term
Size: 2" x 10" x 11"
I've been using the K&N Lifetime Washable Cabin Air Filter in my vehicle for several months, and here's my experience: Pros: Washable & Reusable: Eliminates the need for frequent replacements, saving money over time. Improved Airflow: Noticed a slight increase in airflow through the vents, enhancing cabin comfort. Odor Control: Effectively reduces musty smells, providing a fresher cabin environment. Cons: Initial Cost: Priced higher than disposable filters, but the long-term savings offset this. Cleaning Required: Needs periodic cleaning to maintain performance, which might be inconvenient for some users.
