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.

Quality
Size: 2" x 10" x 11"
My brother put me onto these filters. Super easy to install. Also bought engine filter. One time expense. A bit pricey but cost covered if you were still buying paper ones in about 3 changes of paper ones. Will definitely pay for themselves. Highly recommend
