Quality filters for a decent price
The engine filter is model # JMAJ20. I am not sure of the cabin filter model #. I have a 2026 Honda CRV Hybrid 2.0L Sport Touring. These should fit as almost everything matches between the 2025 and 2026. I have not yet needed to swap the filters in the new vehicle. These filters will be stored for future replacement.
The filters appear to be well made. This is a decent price fortwo filters. The engine filter's gasket is a little wavy but it should be ok to form fit once inserted into the car.
The engine filter is in a retail box without a plastic wrapper but the cabin filter is just a plain cardboard box inside a plastic wrapper. This might be challenging to remember what is in the box later once the filter needs to be replaced unless I write the information onto the box. I am unsure if the lack of a wrapper for the engine filter will affect the filter while stored.
I did not notice a smell to these but I am not sensitive to smell.
I would get these again.

Great value perfect fit.
At a fraction of the cost of brand name filters, these are an exact match and make it affordable to actually change your filters on a regular basis. Great! Installed on a 2025 CRV hybrid touring.

Solid replacement filters for 2025 Honda Civic Hybrid. Engine and Cabin 2.0L Engine
Good value replacement filter kit. Fits perfect for 2025 Honda Civic Hybrid with 2.0l engine. Fairly easy to install once you know how to access the filters. Center rear of the engine bay and behind the glove box. These are as high a quality as the stock filters. I changed mine at 12300 miles and I waited too long. I should have done them at 10,000 max. The cabin filter maybe could have been stretched a bit but the engine filter could have been changed at 8-10k. I would never wait so long again.

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!
