These are for me the 120 mm Red Wings from Xilence.
The filters themselves:
They consist of a massive Meshgitter with a sturdy aluminum frame. So not a cheap product bend the look already at.
They fit perfectly to all my fans and the dust can wash under running water is very simple.
Which I prefer other filters, the inside have a flow tissue because there the dust is much more difficult
again elicit.
I highly recommend this filter fan so here anyone who wants to keep the dust off its hardware, fully warmly recommend.
Mainly due to the good price.
For manufacturers, I can only say Sharkoon has disappointed me so far in any product. Great for those who want a good price / performance.
