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.

High quality cabin filter
Size: 8.3" x 9.3" x 1.3"
I change out the cabin filters in my cars at every oil change. It help when running the A/C all summer. This is high quality cabin filter that does its job. Seeing what the dealer wants for literally 1 minute worth of work is silly.

It works as expected
Size: 8.3" x 9.3" x 1.3"
Great. It does block air flow by a bit, but it is ok, if you don't need strong air blowing your face at maximum setting all the time.

Great cabin filter for 2019 Acura RDX
Size: 8.3" x 9.3" x 1.3"
When I have my car serviced at the Acura dealership, they routinely recommend that the cabin filter be replaced. As we all know, a dealership is going to charge an arm and a leg for a basic service. Therefore, I have been replacing the cabin air filter myself for the past few years. I like BOSCH products and when I found this filter on Amazon, I knew that was the one to purchase for my 2019 Acura RDX. The filter fits perfectly in its location in the glove box. It literally takes less than five minutes to swap out the old filter for the new. I will continue to use this product while I have the RDX.

Perfect fit, easy installation.
Size: 8.3" x 9.3" x 1.3"
This part fits perfectly. Directional flow is printed on the part however you need to confirm which way air flows in the actual air box. The easiest test is to run the a/c with the filter out, wet a finger, and stick in in the air box to see which side the air blows cold. Then just install this part in the air flow direction as printed on the part. I have not noticed a difference in air quality yet, however I imagine being a HEPA filter, this will do wonders keeping pollen out of the car. Installed this in a 2011 Honda CR-Z. Easy installation. Part looks high quality which is fitting for Bosch.
