Overview

Design. The 28mm SMF1 LED bulb is a direct replacement for any 28mm-size bulb commonly found in vanity mirror lights in many vehicles. Populated with one 5050-size SMD the SMF1 upgrades the factory yellowish incandescent bulb to a more modern LED appearance. The SMF1 was designed with an embedded load resistor and implanted diode for superior reliability. With its durable metal terminals it will fit snugly in the socket and its light weight means it won't vibrate loose over time.

Reliability. Unlike other bulbs on the market this bulb is built with constant-current circuitry along with transient suppression. That means this bulb will last for years not months with no flickering or failure. And like every Diode Dynamics product it's backed by an industry-leading three-year replacement warranty.

Brightness. With 16 lumens of true measured output the SMF1 LED will provide similar light output to your original 28mm-sized bulb. If you are looking to increase output we'd recommend checking out our SMF2 option! All Diode Dynamics LED lighting is rated with accurate measured lumen figures not calculations or guesses. We test the true output in-house and provide you the real numbers to compare.

Colors. In addition to vibrant colors of blue red amber and green the SMF1 is available in a cool white 6000K and warm white 3000K option as well. Whether you want a modern cool white appearance or a traditional warm white color we have the color to fit your need!

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!

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.
