Works great on my 2018 Honda Civic EX
Size: 2.0L, Size: 2.0L
Been buying these for years. They are relatively cheap and easy to replace, so much better than getting ripped off at the dealer lmao. Compatibility and Installation - 5/5 Filtration Efficiency and Performance - 5/5 Durability and Value for Money - 4/5 - these are made to be replaced, so can't really do much about that!

Perfect
Size: 2.0L
I bought this and was able to change this myself. It was simple. I got this for my 2016 Honda Civic, I don't think I ever replaced the filter in my car in the 5 years that I had it. It had a distinct smell in my car, and once I popped this bad boy in, within a day or two the smell was gone. It did make a sound for a while like I did not do it correctly, but I did, after about a week the sound went away, so everything's good. I will buy this again when the time comes

Efficient and Easy-to-Install Cabin Air Filter
Size: 1 Count (Pack of 1)
I recently installed the ECOGARD XC35519 cabin air filter in my 2019 Honda Accord, and the experience was straightforward. The filter fit perfectly, and the installation process was quick—taking only about 10 minutes. Since the replacement, the cabin air feels noticeably fresher. While the filter doesn’t include activated carbon for odor removal, it effectively traps dust, pollen, and other airborne particles, enhancing overall air quality. For those seeking an affordable and reliable option to maintain clean cabin air, the ECOGARD XC35519 is a solid choice.

Fits Well!
Size: 1 Count (Pack of 1)
Perfect replacement for my 2024 Honda Ridgeline OEM cabin air filer. Easy install via the glove box too. I also purchased their engine air filter which fits too.
