Great product
Size: 9.3" x 9.7" x 1.8"
I recently installed the BOSCH 6029C HEPA Cabin Air Filter, and the difference was noticeable right away. The air inside my car feels much cleaner and fresher, especially when driving in traffic or through areas with a lot of dust and pollution. It does a great job filtering out odors, pollen, and even fine particles—I’ve had fewer allergy issues since switching to this filter. Installation was straightforward and only took a few minutes, even without much mechanical experience. The build quality is solid, and it fits perfectly without any gaps or issues. Compared to standard cabin filters, this HEPA version is definitely a step up in terms of filtration performance. Overall, I’d highly recommend this to anyone looking to improve their in-car air quality. It’s a small upgrade that makes a big difference in comfort, especially for daily drivers or people sensitive to allergens.

Good quality!
Size: 9.3" x 9.7" x 1.8"
This cabin air filter is seriously a game-changer for my car's interior air quality. I was getting tired of that stale, dusty smell every time I turned on the AC. Swapping it out was surprisingly easy, and the difference was noticeable almost immediately. It really does trap all those tiny particles, like pollen and dust, that used to make my allergies flare up. Now, the air inside my vehicle feels so much fresher and cleaner. I've been recommending this brand to all my friends who are looking for a reliable filter. It's definitely worth the investment for a more comfortable driving experience. Seriously, if you're on the fence, just go for it!

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!
