Great Replacement Cabin Air Filters for my 2008 Honda Civic
Size: 2Pcs, Size: 2Pcs
Item Reviewed: CF10134 Cabin Air Filter with Activated Carbon Replacement for CP134, Fit for Honda Accord/Civic/Odyssey/CR-V and Acura MDX/TSX/TLX/RDX/Ridgeline (2 pack) ℹ️ Summary I picked these up because I needed some replacement cabin air filters for my 2008 Honda Civic. These seem like decent quality and they were a perfect fit in my car. For $15 at time of order for two air filters it was a solid deal that I can glad recommend to others. I hate writing short reviews, but there’s not much else to say about these. Here is how I rate items: 5 ⭐️ = Completely exceeds expectations. 4 ⭐️ = Works well with minor concerns. 3 ⭐️ = Does the job, nothing special. 2 ⭐️ = Some things work, but lots of issues. 1 ⭐️ = Didn’t work well, not worth it.

Good fit for Acura MDX
Size: 8.8" x 9.3" x 1.1"
This is an air cabin filter that will fit many cars, and in my case a 2019 MDX. Since this kind of filter is not doing anything critical like keeping dirt out of an engine, I shop around for non-OEM filters for something that strikes a balance between price versus performance. This filter just filters out dust in a car cabin, and when we’re not in our cars, we don’t have the benefit of an air filter when we are walking around outdoors. At a fraction of the price of an Acura filter, this filter seems to strike that balance. The filter media looks sturdy and is embedded with charcoal to help absorb odors. Installation is very straightforward in my MDX, and similar in most cars. There is a compartment door inside the glovebox that first must be removed before changing the filter. Pay attention to the direction flow arrow that shows which way the filter should be installed. Overall I am satisfied with this filter. It is inexpensive, fits perfectly, and seems to do the job just fine. It is definitely worth trying if you are trying to save money.
