Ventilation and exhaust: Hygienic problems after 5-6 years

Yes, of course there is dust, it has been running for three years and we don't have clean rooms here...with a vacuum cleaner and a brush the rotors looked neat again shortly after the picture was taken...

So my system is relatively simple...you loosen 6 screws and the front cover comes off...the internal components are simply plugged in and can be pulled out to the front as needed....

I was referring to the fact that no dust gets inside - and that’s just not the case

If you add pocket filters to the 2-3 exhaust points, the interior will also be dust-free. Something like "microdust" might possibly get through, but I bet there are other places in the house where more dirt and dust are hidden (under the bed at the back, behind/on cabinets, in the keyboard ....

The image shows the operation with cone filters on the exhaust air valves and the regular filters in the system...

So that's "fine dust". I still think it looks good when I think of my PC, how it already looks inside after a year (despite the thin filter mat).

Yes, I had the same thoughts...
