Quiet PC 120mm High Quality Magnetic Computer Dust Filter Ultra

The quiet pc magnetic fan filters are a classic example of an idea that works so well and makes so much sense that it is difficult to believe that no one has come up with this before.

They completely negate the need for any complicated noise cancelling mounts for the fan filter its self, can be fitted in seconds and are easily removed for regular cleaning. They also look perfectly respectable and have a very fine mesh which prevents the vast majority of dust from entering the system.

If you have a contoured fan opening on your case (e.g. the side fan mount on an Antec 300) I would suggest getting an oversized fan cover. e.g. I have the 140mm fan filter on a 120mm fan, which allows for the fact that the fan grill is raised slightly.

I would suggest manufacturing a better range of sizes so that they can be fitted over the various spaces and gaps on the rear of a case more effectively.

All in all and excellent product. Well played.

I had wondered whether to use this add-on; I wondered whether it would cut air-flow through to the fan. I guess it may be doing that a bit (who could tell?), but it is surprising how much dust is present on the filter after just a couple of days. Since that would otherwise be coating the components in the interior of the case, better on a washable external filter. So, I’m now a…fan.

Firstly I’d like to mention the Pro’s:

They’re nice and low profile, shiny piano black, not at all obtrusive (maybe 2 mm thick tops, hugs nice and closely to the case.

The magnetic strip around the outside is just strong enough to hold it to the case and not slip but not overly strong that I’m worried about it messing around with any of the components inside.

Cons:

The price feels a little too marked up for what they are, at £10.20 inc. VAT (140mm filter) / £8.16 inc. VAT (120mm filter), its a small patch of Polyester mesh bordered with a thin piano black plastic backed magnetic strip.

If you own an Antec 300 case with its outwardly raised fan grills then the side 120mm grill needs a 140mm cover outside or a 120mm inside with no fan. The 120mm filter fits very poorly on the rear grill leaving large gaps and with the case design there’s no room for the larger 140mm filter. You’d need to remove the internal fan to mount a 120mm inside or drill holes in the filter for the fan screws.

This is a very smart product and saved me time and money. Without this filter I had lots of dust in the case… Quiet PC 120mm Magnetic Fan Filter is fully black! I thought I would receive a product like on the picture but I didn’t - I am lucky :) I don’t like the white filter and logo. The filter is only 2-3 mm wide and its design is nice and clear.

It is flexible too! I ordered 3 filters and didn’t know if all 3 would fit ok, but thanks to the material’s flexibility all 3 fit very nicely. The filters can be used inside or outside the case. P.S. sorry for my bad english :(

Having lost my last PC to dust, I’m being extra cautious with this one and have got a case with a filter on the main air inlet. I have a side fan inlet on my Antec 300 cast and bought this.

The problem is that the magnetic area really needs to be bigger than the fan itself in order to stick on properly. I ended up drilling a four holes in mine and fastening it between the fan and the case. Not ideal.
