Great Filter Set for Allergy‑Sensitive Families and MPG‑Minded Drivers
Size: 21-25 TLX, 18-25 Odyssey
I bought this set because I prefer handling routine maintenance myself, especially cabin and engine air filters, rather than paying dealership prices for simple jobs. The package included one cabin air filter and one engine air filter, plus a full backup set for the next service interval. Both filters installed easily and fit the 2018 Honda Odyssey exactly as expected. No trimming, no forcing, and no alignment issues. The cabin filter seated cleanly in the glove‑box housing, and the engine filter dropped into the airbox without any airflow restriction or sealing gaps. This setup is ideal for Odyssey owners who want to maintain optimal cabin air quality—especially helpful for families with allergies—and for drivers looking to keep engine airflow unrestricted for the best possible MPG and throttle response. It may not be necessary for anyone who relies exclusively on dealership service or doesn’t perform their own maintenance. Overall, this is a straightforward, high‑value filter set that installs cleanly and supports both air quality and engine efficiency for DIY‑minded Odyssey owners.

Great Quality Filter and Perfect Fit for My 2022 CR-V
I bought this EPAuto air filter for my 2022 Honda CR-V 1.5L, and it couldn’t have been easier to install. It fits exactly like the original — snug and secure — and the whole process took under five minutes without any tools. Just open the air box, pull out the old filter, and drop this one in. The quality feels solid with a sturdy frame and well-made filter material. It’s not flimsy at all, and you can tell it’s built to last. After swapping it in, I noticed the engine felt a bit smoother, and there was a slight improvement in responsiveness, especially during acceleration. I’m also hoping it helps with fuel efficiency over time. Honestly, for the price and convenience, this is a no-brainer. It’s a simple upgrade you can do yourself that helps protect your engine and saves you money on dealership replacements. Highly recommended if you drive a newer CR-V like mine!
