I've been using one I found used, and it does spark like a bug zapper when it gets dirty or after I wash it, but it only uses 16 watts, has extremely little resistance to airflow and the water looks like axle grease when you hose the filter sections off. It does produce ozone smell sometimes also.
OK, I just went through this.... will try to save you some time while biasing you with my opinion.....
I wanted a air filter. I am always paranoid with wood smoke/ash (even in tiny amounts), my wife has bad allergies, we have a cat, and a little one on the way. So I wanted a air purifier, even if it is just a placebo effect.
1) those ionic filters produce dangerous amounts of ozone, and dont filter worth poop. Skip them!
2) the onyl filter worth anything is a hepa filter
3) filters are expensive to replace, and you know you wont do it on time. Some purifiers have lifetime filters, you can just vaccuume them out (guess you should do it outside).
4) look at the area you want to keep clean. size the purifier correctly! I bought a large purifier for a pretty small area, this way I can run it on low. If you get a purifier that can clean X sqft and put it in a X sqft room, then it needs to run full tilt!A big purifier running on low will probably be quieter than a small one on full power.
I ended up getting a honeywell 50250

There is a really detailed review, with lots of tech specs on amazon, her eis the link to it: http://www.amazon.com/review/RPK089GRGVMP9/ref=cm_cr_pr_viewpnt#RPK089GRGVMP9
thats where I bought it. I am pretty happy with it. There isnt any dust in beams of sunlight anymore. I also looked at the black pre-filter, after 3 weeks its pretty grey. So it clearly pulled some nasty stuff out of the air, every bit of dust that goes in ther eis great, because it is better than going into my lungs (I am saving them for the asbestos in the cube farm at work).
Here is how much power it consumes, I measured with my kill-a-watt.
high - 175 watts
medium - 121 watts
low - 83 watts (24/7 at my electricity rates, this is about $9/month)
All air purifiers will make air noise, on low this one is pretty quiet. Some people report that the prefilter smells for a little while after you open the package. Mine didnt, but open it in the garage if you are concerned. I would deffinitely reccomend it!
Hope that helps,

Chicken, I imagine.The interwebs tell us that 75-90% of household dust is dead skin. What does it taste like?
No, don't really taste it, just kidding.
Thanks for the tips. I am looking at buying 1-2 filters when I move (I think the house I will be renting has carpet) and I hate carpet..especially old carpet that has been walked on and lived on by different people over the years. I will try to avoid eating their skin...haha.
