Filters, Filters, Filters, Why aren't there any?

a1call · 2018-10-21, 01:35

Hi all,
My latest task at my day-job involved a ductwork which had 2 sets of pre-filters Incorporated in its design to protect the inner filters of an industrial blower. The following occurred to me.

* Dust buildup inside a computer casing is the common major cause of overeating and fan failure in a computer

* Fan failure is probably the main type of computer hardware failure

* Why is there (if indeed there isn't any) no cleanable/changeable air filters Incorporated in the computer Case design?

* Why is there no market/in-market externally mountable filter box that covers the air input grills of a computer/laptop casing which hold washable/changeable air filters to eliminate the most major maintenance headache associated with computers.

Thank you for your time and input.

1) Are Americans desperate enough for food to eat computer dust now ?

2) First thought is airflow, second is maintenance.

Airflow will be reduced but it is a calculable, simulateable (CFD) exact science. The filter "Open Area" can be made equal to the grills Open-Area resulting in negligible flow reduction. Plus in the long run the performance should be better than a dust covered grill and internal components.

I think the maintenance of filters is much more ergonomic and effective than routine dusting and vacuuming of computer casing.
Thank you for the reply SM.

That would be cannibalism. In case you didn't know - most of the modern apartment/office dust is ... your own skin cells.

There isn't?!
Even my 10-year old computer case has washable/changeable air filters.

Exercise: type newegg.com, search "case air filter" -- you will get dozens!

Thanks for that Batslov. I have never owned a PC or laptop with the"Removeable Dust Filters" that I know of.
The prices don't seem to be very prohibitive. I wonder why it's not a more common feature.

No one but the more knowledgeable users would ever clean/change the filter(s). This would cause the machine to fail sooner than letting the dust build up in the heat sinks, especially for those that don't drive their machines hard.

I have an InWin 909 case with two fans installed at the bottom blowing up. Directly below them is a removable metal plate covered with very small holes which catch a lot of dust. The plate attaches to the bottom of the case with magnets so it can just be pulled out and taken outside to brush off. This picks up a surprising amount of dust.

That's a beautiful Machine. I would find the internal bluish LEDs problematic in a bedroom location though.
I will make sure my next PC is equipped with Removeable dust filters.
I would even invest in externally mounted filters of if they exist.

Mine doesn't have liquid cooling or the blue lights. They are just showing off a high-end build.

The one that I had for many years was Newegg's own (Rosewill = Newegg) Blackhawk.
I think they discontinued it, but they and CoolerMaster have many like it. And these are not really exotic or obscure brands.

I wash the filters once a year or so and let them dry. It helps because we have a cat :-)
