Fits and filters great
Style: PUREFLOW
Perfect fit and replacement for my wife's car air filter. The air seems to be a little fresher after putting this one in i believe it makes a difference to spend a little more on a quality filter.

Fits 2018 Honda Cr-V LX FWD. Be sure to install this filter with the arrow pointing down. Note that the plastic cover that holds the filter in place has an arrow pointing up to show you which direction to orient the plastic cover, not the filter, which again, should have the arrow pointing down.

A Breath of Fresh Air for Your Car
Size: 8.3" x 9.3" x 1.3"
This BOSCH 6037C HEPA Cabin Air Filter is a fantastic and simple upgrade for your vehicle. It delivers exactly what it promises: cleaner, fresher air inside your car. The installation was incredibly straightforward. It was a perfect fit for my Acura RDX, and I was able to swap out the old filter in just a few minutes. You don't need any special tools, making this an easy and quick DIY project for anyone. The difference in air quality is immediately noticeable. The HEPA filtration does a great job of trapping dust, pollen, and other allergens, leaving the cabin air feeling much cleaner. It also seems to reduce outside odors, which is a huge plus. Overall, this is a high-quality product that provides excellent value. It's an essential and affordable way to improve the air quality in your car. I highly recommend it for any compatible Honda or Acura model.
