Verified Purchase(What is this?)
This review is from: DEMCiflex Dust Filter 120 mm Black and White (Personal Computers)
I bought two of these to serve as the filters for the underside air intakes on my case. The magnets were so weak that they would not grip the bottom of my case properly, even when using the provided adhesive magnetic strips. They just kept falling off. To add insult to injury the weak adhesive on the magnetic strips also gave way.
These filters will only work if the intake/exhaust you are trying to cover is completely flat, which is not helpful given that most peoples' case vents will have slightly raised grilles or screwheads.
I have resorted to ripping out the mesh and taping it onto the bottom of my case for now until I get some decent filters that I can attach with screws.
