**Looking for good fan filters**

Hi everyone i am pretty new here and let me start off by saying just from browsing i have learned a lot from you guys and i am asking you for your help once again...

Right now i am in the market for some 120mm fan filters to keep the dust out of my 900, i want something that would keep majority of the dust out but at the same time not take away from the air flow.

Does anyone have suggestions that they can make as far as something to fit what is needed??....please leave your input as well as any recommendations and even pictures would be appreciated!!...thanks

crazypc has filters.

Pantyhose.
or used dryer sheets.

Its either airflow or dust. Be it cleanable metal mesh or nylon threads, airflow is killed. 3M Air conditioner filterite does a great job of it just that it comes with a premium price tag.

I only use metal fan filters, nylon and pantyhose arent has durable

yea i figured it was either or i guess ill try a few filters out and see if i get any drastic changed in temps, ill post here once i get the filters
