Good OEM replacement for Honda Pilot
Size: 7.5" x 8.7" x 1.4"
Simple cabin filter for my wife’s Honda Pilot. It fits well in the cabin air filter drawer. This is of similar quality to the original Honda one; just cheaper. I’ve bought this for my Subaru and have been happy with it as well.

Works great!
Size: 7.5" x 8.7" x 1.4"
This is a great filter for allergies and a huge help during allergy season. It traps fine dust and pollen much better than the standard paper filters you get from the dealership, resulting in noticeably cleaner air inside the cabin. The construction feels very solid, and it fit perfectly right into the housing without any issues. If you are looking for true HEPA filtration in your vehicle, this is definitely worth the upgrade!
