When you open your PC after six months, perhaps to install new hardware, you often wonder if all the dust in the universe has settled inside your case during that time.

The easily cleanable aluminum filter cartridges provide a solution, as they are attached to case fans and ideally prevent any dust from entering the case. The filter grid must be secured to the fan with four screws, which are not included in the package. The filter is made entirely of aluminum and can be easily cleaned.
