If you own a compatible Honda/Acura vehicle, replacing the cabin air filter on your own will be the easiest $60 you'll ever save. Depending on how much stuff you store in your glove box, this should take no more than 10 minutes to complete, but probably less.

The Acura dealership suggested I replace my cabin air filter during a routine maintenance (oil change for an A1/B1 service) and wanted to charge an extra $70 (parts & labor) to do it. When they showed me my dirty filter, I honestly didn't think it looked that bad, but I declined because I knew how easy it was to replace on my own and how inexpensively I could get the FRAM filter for. As soon as I got home, I ordered two units of the FRAM filter from Amazon--one to keep on hand. Once I received it, I went out to my car and installed it myself in 10 minutes. It only took that long because I reorganized my glove box a bit when I was putting everything back in.

The box comes with written instructions for your vehicle, but if you need it, there are plenty of helpful YouTube video tutorials available as well.

I noticed my air conditioner air flow was reduced when I put my Honda Ridgeline AC system into Cabin Air Recirculate mode. I opened the cabin air filter compartment and verified that the Recirculate flapper was actually working. It was. I then pulled the "FRAM" CF10134 filter out and cleaned it. I checked my records and found I had replaced it only 2 or 3 months ago. It just had a few leaves stuck in it so I used compressed air to blow any dust out from the back side. There was no dust being blown out which was unusual. When I examined the filter it seemed the filter material was quite dense, unlike other filters I've used. I had bought several of these at the same time so I checked the box and they are labeled as having both baking soda and carbon infused in the material. That would certainly add density. So my reason for one star is: (1) apparently reduces air flow noticeably....this may put undue drag on the blower motor which could potentially reduce it's life (2) the description states "provides more air flow" which I guess could be true if your old filter was severely clogged (3) the description states "keeps damaging particles from entering the engine and causing increased engine wear......that's just a simple marketing error...right?? (4) the item pictured for this item shows a side view, but it's missing the "MADE IN CHINA" text which my filter has written on it. Maybe what I got is a cheap knockoff?? and (5) relatively high price.
My conclusion: if airflow is not an issue for you, then you might like this product as it could potentially filter out some odors for a period of time until the activated carbon and baking soda loose their filtering capacity. That's assuming that actual baking soda and real activated carbon have been used in the filter media.

Honda Owners - Do yourself a favor and save some hard earned cash. The dealer wanted $27 to replace this filter. It was dirt cheap on Amazon far less than half the cost with free shipping for Prime. Prime is worth every penny!

In my Accord and my wife's Odyssey the filter is directly behind the glove box. You have to pop out the glove box to do this. The glove box has a stopper bracket on the right and left to keep box from opening too far. You have squeeze the brackets and let the box keep swinging forward. It takes all of 5 minutes including time to find your smart phone and search for a how-to-video on YouTube, watch the video and replace the filter. I did it less time than it took to pump a tank of gas.

Shame on Honda for giving no help or pointers in the owners manual other than have a dealer do it.

After installation, I experienced cabin air gush (running the AC fan full speed) I have not experience since having the vehicle 7 years ago. I can actually feel the air gush in my face sitting relaxed back-to-seat (running A/C fan full speed). However, from the dirt in the filter, I conclude the filter has never been changed since original 10 years ago (See the pictures). BTW, I never know there was filter underneath the dash - I found this out from Amazon recommendation (Thank you Amazon! Where has my mechanics being - they never mentioned the filter!?)

I didn't realize how nasty the old filter was until I put this new one in. Replacing the filter was a breeze (pun intended). My 2011 Acura MDX (like many vehicles) places these in the glove box (actually behind it), and all I had to do was empty everything out, squeeze the semi rigid sides in a bit and let it drop all the way down to open up various hidden things, including the cabin air filter location.

Do note that these filters are directional, so note the dirty side of the old one and make sure the new one points away from what was the dirty side. My car had arrows on the frame which helped too (if nothing else, the air usually comes in from between the windshield and hood and goes down from there). My frame had a place to slide the outer bits of the filter to prevent air from bypassing the filter, so look for that.

5 stars for the filter and it's very easy to do.

0 stars for Acura having the manual not show how to replace this (merely tells you to go to the dealer, who charges $75 to replace this).
