Sorry it didn't work out for you. But thanks for the heads up warning me off! That's a big help! Yeah. Your furry critters may have been too much for it to deal with. But I just saw this comparison test where one of the Sharper Image units (and an Oreck or two I was also looking at) didn't seem to fare too well: http://www.air-purifiers-america.com/ed_APA_test_results-large-room.asp [Double hairy rats! That Alen A350 didn't look too bad - but the filters are $140 a year! Hmmmm. I'm seeing a significant price difference in filter prices between HEPA and non-HEPA filters. Looks like you have a choice of filters with some of these units. More research may be indicated.] VACUUM JUNK: >>we just replaced our old semi-expensive-but-crappy vacuum cleaner with >>an expensive "doesn't lose suction" job, and the amount of stuff it pulled >>out of the living room rug on its maiden voyage was /phenomenal/. :-) Neat! Those things seem pretty cool. The technology sounds like a really good idea. Ummmm. Actually, I did some quick on-line price comparisons of the new Dysons against the old 'big three'; Rainbow, Electrolux, and Kirby. ALL of the prices seem less than what I think I remember spending on mine ... 20-plus years ago. Rats. Looks like I got ripped off. ;-( Dang. And I knew the guy too! Of course, I *did* get every attachment in both the known and unknown universes; the shoe polisher, the sander, the body massager, the carpet shampooer, the paint sprayer, the zip brush, etc. In fact, I think there are a few things I may never have actually figured out how to use! Oh well. I just gave her a good cleaning recently and she's working fine! Now if I could just convince myself to put her to work on a more regular basis! RonL.
