Coffie filters as intake filters

edited December 2003 in Hardware
I know the title might sound like something for the pub but i'm serious. Would it be possible to use the filters for coffiemakers as intake filters in cases. Since the frontbezel can be open to show the intakes why not put some homemade filters there. The plan would be to use ducttape or similar to fasten them. My current old case doesn't allow me to do this but would it work for newer cases. Or would it block so much airflow that i'd be better of with real airfilters.

Just to show you what i'm talking about.

    may restrict the airflow too much but who knows ...try it and watch your temps.

    hmmm

    coffee filters... i'd say give it a shot. watch your temps and get back to us. it's a good idea, but remember like all filters, don't forget to change them on a regular basis.

    IMHO, it's going to be WAY too restrictive.

    "In the interest of science"....I just went and grabbed a generic, unbleached coffee filter. I stuck the flat bottom portion up against my mouth and blew. At a rough estimate, the airflow was 5-10% of the speed of a normal "blow".:D Ya, you there in tha peanut gallery, shaddap. Anyways, I also tried sucking through it. I'd suffocate in <10 minutes trying to breathe that way - and so will your computer, is my conclusion. ;)

    Yea it sounded like a good idea until i tried the suck'n'blow thing myself. I almost suffocated as well. Looks like it's no skimping on those then, not that they're that expensive.

    I said that i couldn't test it on my current case since it has to many holes so the air would take other routes and besides my mobo only messures its own temp. I've got no other tempsensors.

    Does anyone have any ideas for other lowcost homemade airfilters that would work. Let's get the ideas rolling.

    I truly admire scientific curiousity. Being a fan of a good laugh as well, this thread is shaping up to be a winner.
    :vimp:

    I've heard of people cutting up panty hose and wrapping it around the fan grille.

    Plus: You seldom hear of a bank robber suffocating... :D

    Right. I knew better :rolleyes:;D:buck:

    Ehhhmm, haven't tried pantyhose..as a filter..:wtf: Have used super cheap humidifier filter insert material, it's about 4mm thick and a sort of porous bubble plastic kinda stuff, can buy about a 3' roll at Home Depot for a couple bux then cut up the size you need for filters. Works OK.

    Right. I use spun fiberglass furnace filters you can buy 4 for 2.88 at Walmart and cut them to fit the front inside of the case. I've yet to go thru more than one sheet (20x20x1) in the last year. Works great.

    i like mgk's idea better than the coffee filter anyways. i mean coffee grounds are kinda small so the holes in the filter have got to be even smaller. i just wanted to see if it would work ;)

    I use register vent filters. I got a whole-bunch (like 12 or so) pack for about $4 at Wal-Mart. They perfectly cover the two 80MM intake fans on my Chieftec cases. Knocks the dust inside the case down by about 90%.

    I think these may be the same material as what MGK is talking about?

    You might look in the local speed shop for foam filters for filtered velocity stacks as it's a nice open cell foam that flows air really well and I can testify to them flowing 850-900cfm in a 9" diameter.
    I have the same type of foam on the stock intake filter on my case and it flows like a charm and really cuts the dust down.

    Are those washable too? About what price?

    Ummm...Back in my street racing days they were about 5 bucks and they were gas washable so I assume that water won't hurt them.

    Thanks for the suggestions guys. I didn't think that anyone tried homemade stuff. Hmm pantyhose how to buy them without feeling stupid. There aren't any speed shops that i'm aware of. Maybe auto supplyers have them.
