What I thought as a "dust filter" is a unit you buy which just filters the air. It makes more sense now that it's in an air conditioner.QUOTE]
The unit that just filters the air works, if you get a decent one. The problem is that large ones can become expensive. I have a Honeywell that is rated for 700 sq. feet that I got for my birthday last year and I sit it directly in front of the intake on my central air/heat unit. I figurethat helps circulate the air over it more.
As for how well it works; when I change the carbon prefilter (haven't had to do the HEPA yet) it looks like I shaved my cat and pasted the fur to it. It also has a good couple of millimeter thick layer of dust. And that doesn't even include the stuff caught in the HEPA filter. There are noticable effects as I have to take allergy medicine whenever I am at work, but on the weekends I am fine without any as long as I stay inside.
My best friends has a small one he just keeps next to his cat litterbox and all signs of cat smells are gone.
I agree with you on the filtration units, though. They suck. I guess you'll just have to be cleaning your PS3 more often.
Just don't use the Ionic Breeze type. In my opinion they don't seem to do as well. My asthmatic brother has one and it helped, but not a lot. He ended up buying the same model as my Honeywell HEPA filter. The ionic breeze just doesn't move the air enough, whereas my HEPA on high sounds like a jet taking off and blows enough air to create a chill, like a fan.
That would be an even greater reason to install an air filtering system... not just to keep the dust down, but for your own health. 👍
Yes, some air filtering systems are a joke, but others are certainly not. A good resource for reading, comparing, and getting unbiased analysis of these types of systems is
Consumer Reports.
See, DN knows what he's talking about.
Anyway, to pull this on topic, since getting the air purifier we don't have dust building up on things nearly as much and I hardly notice the floating cat hair that can become common in a cat owner's home. I rarely have any dust problems with any of my electrical devices and I would bet money that the use of one would help with the PS3. My PC has a flap over my memory card and USB slots and once I got a camera that actually used an XD card I found the slots full of dust. I cleaned them out and haven't had any build up since.
