I picked up this Puroma cabin air filter to replace the old one in my Honda and it has worked out very well. It fit the housing just like the original, slid in without any forcing, and the whole swap took only a few minutes. The construction feels solid for the price and the edges seal properly so air is not just bypassing the filter. After installing it, the air from the vents smelled noticeably fresher, especially when using recirculate. The activated carbon layer seems to help cut down on that stale or slightly musty smell that builds up over time. For something that is easy to forget about, changing this filter makes a real difference in everyday driving comfort. If you have a compatible Honda or Acura and want an affordable replacement that you can install yourself instead of paying dealership prices, this Puroma cabin filter is a very practical option.

Excellent Air filter - Easy installation.

Style: BE-743 1-Pack

Excellent AC and Heater Cabinet odor defense air filter. I noticed immediately the smell coming out of the vents was fresher and the musty smell that was coming from the vents was crisper and cleaner. Very easy installation that you can do yourself and don’t need to pay a shop to do. The price is one of the best online and coms in quickly. It’s very sturdy, filter quality is excellent and it definitely improves the air quality and flow in your car. Fits perfectly like any OEM filter, this is a great buy for the price of an installation that will take you Les then 10 minutes to do yourself.
