About this item

  • Bosch HEPA Premium Cabin Air Filters are designed and tested to meet High Efficiency Particulate Air (HEPA) standards based on ISO 29463-3:2011 and provide filtration efficiency of 99.97% at 0.3 microns
  • This efficiency provides ultimate protection in trapping particulates that can enter your vehicle and provides the cleanest air possible for you and your family
  • Melt-blown electrostatic layer and very dense media provide greater trapping capabilities; Additional static cotton layer added to the HEPA media provides higher capacity
  • Structural ribs incorporated into design ensure filter integrity, increasing the stability of the filter for optimum performance over its lifetime
  • Bosch HEPA Cabin Air Filters provide true clean air for enhanced respiratory health without an added chemical odor neutralizer; Cabin air filters should be replaced at least once every 12 months (or every 12K miles)

Great Filter

Kyla JanelDecember 23, 2025✓ Verified purchase

Great filter! Fits in perfectly. I have noticed the air in the cabin of my car to be a lot cleaner. The filter is pretty thick so this filter should last a while. This is a replacement filter for me so the filtration has always been really good. Definitely worth the purchase for a Buick Encore! Read more

Saved Me $80 and Took Just Minutes to Install

Mrs WhiteApril 22, 2025✓ Verified purchase

When I went in for an oil change, the lube shop tried to charge me $80 to replace my cabin air filter. That seemed ridiculous, so I decided to do a little research. After watching a quick YouTube video, I realized how simple the process actually was. I ordered the BOSCH 6091C HEPA Cabin Air Filter, and honestly, I couldn’t be happier with it. The installation was straightforward, and within minutes, I had a fresh filter in place—without paying an outrageous fee. What I Loved: Easy DIY Installation – No special tools, no hassle—just pop the old one out and slide the new one in. High-Quality Filtration – The HEPA filter does a great job of keeping dust, pollen, and other particles out of the cabin. Cost-Effective – Instead of paying $80, I spent a fraction of that and got a top-tier filter. Immediate Difference – The air inside my car feels cleaner, and I no longer get that stale smell when turning on the AC. If you’ve ever been quoted an absurd price for a cabin air filter replacement, don’t fall for it. Grab this BOSCH HEPA filter, watch a quick tutorial, and do it yourself—you’ll save money and feel pretty accomplished in the process! Read more

It fits as a basic air filter

AHG3rdFebruary 16, 2025✓ Verified purchase

This is a good basic Cabin Air Filter. It replaced my last STP Max Cabin Air Filter, CAF1904M, with Anti-bacterial micro tech to fights viruses and bacteria, which was much sturdier and I think was better filter. Read more

Reliable product and have ordered again.

Teresa M. CookJuly 29, 2025✓ Verified purchase

Imagine having almost 35,000 miles on your vehicle before finding out that the service dept. at our dealership has never checked it since it was bought while noting it on the check list for an oil change that they did. I found out about changing this on a Chevy forum so watched UTube to see what it entailed. This product is exactly what I needed, ordering it was a breeze, quick delivery, and much better than the original. It was easy to install after watching the video with the exception of the way Chevy has a screw that you have to get it around. My husband actually notched the plastic part that holds the filter in so ready now to change the next one in 6-12 months. Read more
