DEMCiflex Computer Dust Filter, 2 x 80mm ID Rectangle, Black Frame/Black Mesh

It's really good that DEMCiflex creates and labels each custom filter as OD (Outer Dimenions) or ID (Inner Dimensions). I appreciate them adding images with the measurements for OD/ID which is crucial for anyone wondering the actual sizing of the mesh and magnet.I always go with ID (Inner) because they leave more air space for airflow and provides room for unique fan screw buldges. Their filters always come with a thin ahesive frame cut-outThe ONLY concern going with demciflex is that their products almost always come covered with some of the dirty metal dust during manufacturing processes. It will feel like dust when you first put your hands on them. It can get stuck on your hands and are probably not healthly to accidentally inhale/ingest so beware. Make sure to wipe them down and wash your hands after handling them.General review of DEMCiflex = Some of their filter prices are somewhat unreasonable but I mean hey, when they're the only company that does custom pc dust filters with "FINE" quality mesh, you can't really complain. The only other company I know is Silverstone but they only do 120mm, 140mm single filters.If you're wondering, the case in my review photos is the Rosewell RS-MI-01 BK iTX case on both sides..

This is a 2 piece unit that has a magnet that adheres to the case, and the filter itself that is removable allowing you to easily clean it. Well worth getting.

Improved pc case airflow.

NOT MAGNETIC as specified in description... who wants to adhere a dust filter to their case?? Should be mechanically fastened / removable
