Dust filter on exhaust?

My PC has a 360mm top mounted radiator acting as an exhaust. I have a dust filter on it, the top grill over that (o11 Dynamic).

Should I have the dust filter there?

I have one in mine but now I’ve read this and thought about it, common sense would say no. It’ll block airflow and if anything you want it to push out the dust? I’m going to remove mine now!

(Unless someone who knows more says otherwise!)

Yup I also just out of the blue came to the same conclusion.

Ok I'm taking mine out.
 
Another for filtered intake vents with no filters on exhaust vents, unless you notice dust on them and on inside of case around them. Dust collecting in case near exhaust vents is usually the result of vents flowing air in instead of out. ;)

It'll block airflow as much as the filter on the intake.

Now you're in a dilema ;)

Indeed!

Our cases flow the exact same amount of air thru intake vents as thru exhaust vents. Sure, air does compress and expand. Phanteks T30 fans make 7.22mm H2O at full speed, dropping down to 3.3mm H2O at 2000rpm and only 1.27mm H2O at 1200rpm.

For comparison as to how little pressure difference 1.27mm H2O, 3.3mm H2O or even 3.3mm H2O is, there is 1.836 mm H2O less air pressure on neck (5 feet above sea level) than there is on our ankles when standing at sea level. ;)
 
Never need a dust filter on outtake, you will be restricting the air trying to get out.
 
Filter on the output is basically the same as Superman wearing his underpants on the outside of his tights.
