air purifiers remove dust from computer cases?

[supiammike]

i dont know if this goes in highly technical or in cooling and cases so if i posted in wrong spot ill change topic...

I have seen lots of air purifiers requiring filters and the filterless ionic breeze... are there any reviews on how much dust will be lost from your cases by using these air purifiers?

i would like to have the filterless type... does anyone have one and notice a difference in their computer case?

be careful of the magnetic ones because they can and do create dirt spots around the unit which are hard to get out, because they magnetize the dust particles

 

[supiammike]

you mean i should keep them away from my case and stuff? so they dont get magnetically attracted to my aluminum lian li...

do they only get attracted to metal or just anything?

what are some good generic ionic breeze type?

 

[0roo0roo]

ionic breeze = low efficiency and creates icky ozone, bad stuff.

look at consumer reports, it comes out dead last.

lower dust in air around pc = less dust iin pc. pretty simple.

the hepa filters are good but way more expensive, just do a monthley(or weekly) cleaning of the inside of your PC it may take more work but it would stay clean

you will always have dust in your case. you can reduce the amount of dust by having positive pressure with the intake filtered, and cleaned. and keep the area around you clean. and my air filter is near my computer for a reason. by positive pressure, i mean more intake than out. and filters, filters filters. i use metal mesh filters on my intake. and believe me, i do have positive pressure.

This may be a stupid question. But what is the reason for cleaning the dust from your case?

 

[Burner]

As someone mentioned the best way is to keep your case positively pressured. To do this have higher inflow then outflow (more fans or higher speed fans) Then you just filter the inflow. The cheapest easiest way to do this is to take some old nylons and put them right before the fan.
I did this on a case and it worked amazingly well.

Aesthetics mainly. Also, dust clogging your fans causes them to work harder and less effectively and theres a SLIGHT chance that conductive dust could short a track. But mainly its simply because a dirty case looks gross.

Dust can also create an insulating layer around the various components of you PC, raising temps.

dust can also short things out, some dust can conduct....

What about just putting simple filter over the intake fans. I use a rackmout 4u case as a desktop, I have a filter over the intake fan, a 120 mm... And that keeps junk out. There aren't any openings in the back exept for my dual fan powersupply. air goes filtered intake ----> past cpu ---> out thru powersupply. Otherwise it's completely sealed. I have a 1700+ overclocked to a 2000+, it keeps the cpu at 45 and the mainboard sensors says it's 32 degrees celcius. The psu has a thermal control that only kicks in after playing a long game in quake or compiling stuff or whatever.

All you have to worry about then is the gaps around the cdrom and floppy drive... You can fix that with some tap or something. Use some foam tape or masking tape. If you care about looks, put it on the inside or something.... or just make sure that your intake fans are going to flow just a bit more air then the exit fans for the positive pressure thingy to create a "air seal".

your lungs process plenty of dust. but your skin generates alot of dust as well. just blast some compressed air into the case every once and a while as any type of working air purifier would just waste electricity in the long run

yup. those really pathetic fan filters many people use aren't worth much. big holes catch only the biggest dust particles. and the ones with tiny holes block air, and fans are bad at fighting backpressure. you probably lose as much cooling through loss of airmovement as you'd lose over dust i've yet to see a hepa fan filter you'd need a bunch of fans in seiries to force air through those suckers though haha. its not worth bothering with. get a decent case and it'll have a door, and maybe even a window. every couple of months bring out the can o air and blast away. i blast along with a vacumn hose to suck up the dust blown into the air. you have to change or clean fan filters anyways, and the more they work, the less air goes through and the more heat stays in your case. not worth the effort unless you live in a p ile of dust.
