Cooling Which 120mm dust filters?

I've decided to buy some dust filters so that I'm not constantly having to remove the filth from my radiators. However, there seem to be quite a selection available.

I'm after something that will not impede the airflow too greatly and has a detatchable center for cleaning, so that I don't have to unscrew them every time.

Any thoughts would be appreciated.

Cheers.

 

I use these which are very effective on rads. There's an old review at here

They're not quickly removable though.

 

I use magnetic dust filters which you just slap on at the back of the case outside

They do impede the airflow slightly. My CPU temps increase by 5c, and then by 10c if its full of dust.

 

Thanks for the links guys.

@ Big elf - I did have a look at those, but I was really after something that could just slide out for washing.

Magnetic filters are no good to me unfortunately, as they need to mount straight to the fans.
