ECOGARD XC35509C Premium Cabin Air Filter with Activated Carbon Odor Eliminator Fits BMW 528i 1997-2000, 530i 2001-2003, 525i 2001-2003, 540i 1997-2003, M5 2000-2003

Perfect fit. Installed in under a minute for both sides.

OEM fit for BMW E39 series with plastic frame/tabs/foam. The old filter that I removed obviously was not OEM, no plastic frame and tabs.

Simply put, these filters fit more snugly than any of other brands I have tried. I replaced air filters, but the way they fit in the housing I always wondered why exactly I was doing it. It looked like any air would go around them anyway.I haven't replaced these yet but I suspect they'll have caught more dirt and gross stuff than any of the ones I've had in there before. Can't tell too much of a difference in terms of interior smell, but I'm blown away by the quality and appreciate that someone's making cabin filters this good!

They work, and they work well! Some will review this product and claim that the fit was "so tight that I had to trim the edges and cram the darn thing into place! Then, I gave up!" Don't believe it and don't manhandle it when trying to install your new cabin air filters. Yes, the seal is tight when installed, but isn't that what you want in an air filter? One more thing: I couldn't tell the difference in materials used to make these cabin air filters from the ones that were previously in there. You wanna save money? Here you go.

Fit perfectly in my 2003 BMW 525

You can’t beat the value for money, easy to install and noticeable difference

These filters fit my 2003 BMW 525i well, and I could feel the quality of the product. Reasonably priced. Won't know the mileage until their time is up, though.

The pictures show a filter with a nice rubber seal around the edge and really thick, plush looking filtration media. The filters I received have a foam seal, and the filtration media looks less plentiful, flatter, and cheaper. Almost looks like paper. Still works great and keeps odors out, but I was expecting a higher quality filter.
