Anyone use dust filters on their miners?

I was meant to update this but as usual I forgot. I bought a cheap 120mm filter and took the filter element out and placed it over the intake fan. The suction held it in place. Within 10mins the temps had risen 10degrees although they settled at around 65-66c with the heat we've had the last few days (30c) I'm not happy leaving it on. As you guys have said already, it's not a major issue. I've tried it and it wasn't suitable for me.

Um, don't do that. Typical small fan filters, even simple wire screens, slow down the airflow way too much. Ref what I do using open-cell filter foam https://bitcointalk.org/index.php?topic=1512186.msg15348138#msg15348138

That stuff give me only a 1-2 deg temp rise and also greatly reduces and even sometimes eliminates the siren effect.

Sorry NotFuzzyWarm, I didn't see your post on this thread I would've replied sooner. I found that aquarium filter foam has had a good result. I assume its the same open cell type structure you have mentioned. You can almost see through it. But it works well without distrupting airflow. Fans still set at 20% and temperature rise was only about 3-4degrees to 53-56c with an ambient of 22-25c.

Good result overall, saves some dusting and doesn't affect temps too much

I think that dust filter will reduce fan efficiency and increase temperature in the miner.
After all, after running miners for 2+ years, never had significant problems with dust since the fans are running high rpm.
Not using dust filter would be better for the miners in the long run.

It depends on dust amounts in the place you mine.

I was operating a SP30 in a dusty room for 4 months (it was actually a mechanical workshop, imagine the dust!)
I opened the miner and it was relatively clean. An ordinary desktop computer would of course be full of dust.
Maybe the high speed fans prevent dust accumulation.
