Noticeable upgrade in air quality and a seamless installation
Size: 9.3" x 9.7" x 1.8"
I'm generally skeptical of the "HEPA" marketing for automotive filters, but after installing this in my Honda, the reduction in exterior odors—especially exhaust and pollen—is actually significant. The construction feels far more robust than the flimsy OEM paper filters I’ve used in the past; the pleats are dense and well-reinforced, which gives me more confidence in its filtration efficacy over a 12,000-mile interval. Installation was straightforward and took less than five minutes. It’s a precision fit with no gaps around the edges, ensuring that all intake air is actually being routed through the media rather than bypassing it. One thing to note is that you might notice a very slight decrease in max fan velocity due to the increased density of the HEPA material, but the tradeoff for cleaner air is well worth it in my opinion. If you live in an area with high pollution or suffer from seasonal allergies, this is a legitimate quality-of-life improvement for your daily commute.

Exact fit!
Size: 9.3" x 9.7" x 1.8"
Was a great replacement for OE on my 2012 Honda Accord. It was the exact same size as the previous filter and has no strange smells or odors. Very easy to install behind the glove box and looks great!

Great Filter, Good Quality!
Size: 9.3" x 9.7" x 1.8"
The beauty of this filter is that it comes with very clear instructions on what to do. Not a lot of manufacturers. Give clear instructions. I got this for a 2007 MDX. The packaging of the product itself was well done by Bosch. Installation was a breeze and as soon as I turned on the air conditioning post installation, I could tell the very clear difference. Plus, I also got an opportunity to look at the old filter which was filled with the usual culprits and debris. The initial airflow did have a mild smell of kerosene or like fuel. But this could also be because of the filter component itself needing to be vented out. I would recommend keeping the filter out for about 30 to 60 minutes before installation. Once installed, however, the improvement in air quality was very evident. The fit was very good as well. Highly recommend this. Very high quality.

Cheaper & Higher Quality Than OEM Filters
Size: 9.3" x 9.7" x 1.8"
This Bosch Filter costs less than an OEM Filter and is significantly better because it's a HEPA filter unlike the cheap filters that most automotive manufacturers use. Can't go wrong with this!
