Good replacement parts and affordable
I acquired this filter set to replace the OEM filters in my wife's Honda Accord. The filters fit perfect and were easy to install. Normally when I replace filters I have to purchase both the air filter and the cabin filter separately. In this case, it was very nice to have them sold as a combo set. While I don't know what materials are used to manufacture these filters, I will say that the air filter looks just like the OEM part in terms of it's production. The cabin filter does have carbon built in to help control orders, which is something the OEM part did not have, so it looks different in terms of filter color. I normally replace filters every 10K to 15K miles, and this fits in line with that this manufacturer suggests (every 12K miles). In all, a decent combo set of filters helps keep costs down and both filters can be replaced at the same time.

Perfect!!!
This is exactly what I needed. Fits perfectly for my 2018 Honda Accord as well as being very easy to install. This is coming from someone who has no idea about doing anything on my car. Provides the best function, just as it would coming from a dealer or other auto shop. The quality is great as well, and this is exceptional value for the money. If you are looking to save money and not get bombarded with the filter replacement question when getting an oil change then this is the one for you.

Fit is good.
Filters fit and look essentially the same as the filters I’ve purchased and the official types from the dealer. I live in an area where wildfires occur almost every year, so it’s good to have an extra set of filters to change them out after a run of smoky days.

Fits Toyota 2010 FJ cruiser
Perfect fit for a Toyota 2010 FJ cruiser. Install might have been the easiest cabin filter I've done in any car that new. Remove glove box, pull out the cover and replace it. Fits great and takes odors out from it sitting for 6 months in the driveway. No notice to less airflow when on any level of fan speed.
