How often do you clean your PC?

[Pixelfie]

And does your case have dust filters?

[shikari2007]

Dust filters get a clean every fortnight, the actual internals get a minor once over every month, with peripherals/monitors getting the once a week treatment, The joys of owning cats and being slightly OCD on keeping the PC clean with it being a feature in my livingroom lol

Not nearly often enough.

I clean it once, before I sell it. I build a new computer every couple of years, and it doesn't really get dirty.

No dust filters, and I clean it whenever I notice that it's dusty.

It's likely going to get dusted when I upgrade my graphics card (hopefully) sometime soon, as I have to pull a lot of stuff out.

I'll occasionally wipe down the dust filters, but my desktop really only gets a full cleaning whenever I do a hardware upgrade. It doesn't get dusty enough to warrant going out of my way to open it up and clean it.

I don’t use filters and I have the mesh removed. I blow my machine out once per month whether it needs it or not..

My new case (Lancool 2 Mesh), I wipe off the front and top when I see dust build up. 

We have 8 cats and No carpet. 

When I install my CPU cooler and case fans, hopefully a NVMe drive as well soon, I plan to wipe down the interior. 

At least I don't put the case on the floor anymore.
