Great quality Cabin and air filter bundle pack. Very solid quality.
Size: 18-22 1.5L, Size: 18-22 1.5L
First off, I like that it's a combo pack instead of me having to buy each one individually and being able to change both at the same time. Now, I must say the quality of both of them is fantastic; I'm really impressed. It's not made out of cheap junk; it feels solid and seems like it will do a good job filtering out all the debris and dirt. It was extremely easy to install and fit perfectly like an OEM air filter and cabin air filter on my Honda Accord. The cabin air filter is definitely a solid piece, and you don't have to worry about it getting crushed or deforming as it's padded, I would assume the reason for the padding on the side of the cabin air filter is that no debris or dust sneaks through which gives it a snug fit which is very smart honestly. The same applies to the air filter that goes under the hood; it definitely feels like a quality piece. A quality filter definitely keeps outside odors and smells from coming inside the cabin, allowing you to get fresh, clean air when you turn your AC on. Overall, definitely a solid purchase, and I will definitely be back to buy this exact bundle pack in the future as it's well-built and fits like a glove. So, you're definitely getting great value for your money with this specific engine and cabin air filter combo pack. There are a lot of garbage ones out there, so if it were flimsy and felt like a cheap filter, I would be giving this one or two stars. But I'm actually quite impressed with this company, and it seems to be doing a fine job. My AC does work better after installing these new filters, and of course, the car runs better with the air filter installed.

Good Fit & Quality
Size: 14-22 2.0L hybrid, Size: 14-22 2.0L hybrid
This set which includes both the engine and cabit air filters are of good quality and fits my 2020 Honda Accord Hybrid well. The engine filter feels sturdy and well built. The cabin filter, although without charcoal infusion, has many folds which is more important when it comes to effective filtering of particles. The installation was easy and for the set, this set offers a good value.

Perfect fit!
Size: 14-22 2.0L hybrid, Size: 14-22 2.0L hybrid
This is a good value for a combo package which includes a cabin air filter as well as the engine air filter. Both filters were a perfect fit in my 2019 Honda Accord hybrid. The cabin air filter airflow direction is clearly labeled and the pleats are sturdy. Installation was super easy- just drop the glove box cover, pop the cabin filter cover plate, pull out the grungy old filter and pop in the new one. Easy peasy. The engine air filter is also a perfect fit. No complaints or concerns here.

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.
