Hi Gang, Been thinking about picking up one of them room air purifier thingummys. Anybody know anything about those? Do they really help folks with allergies - or izzit all a buncha malarkey? Maybe it's onna them 'it depends'? I don't really wanna spend thousands on some whole house Swiss or Swedish (ever notice how these are always made in countries that start with the letter "S"?) HEPA rated multi-tonnage "system" with radiation germ-killer laser-headed shark technology! ... Although, I have to admit, those little laser-headed shark critters ARE friggin' adorable! Nope, I'm hoping to 'cheap out'. I'm more interested in a stand-alone no-filter room unit in a more reasonable price range. Like maybe a middle of the road Sharper Image unit kind of thing. I mean, seriously, some of these boogers have replaceable filters that cost more than I want to pay for the whole darn unit. Like pretty much all the ones on this page: http://www.airpurifiers.com/products/iqair/ $300+ for gas cartridge filter replacements? I don't think so! I don't think I need quite that kind of quality. I don't need hospital or chip manufacturing 'clean room' kind of clean. I'm not planning on running a home 'alien abduction probe retraction service' ... Well, at least not until maybe *after* I retire ... "It's all right Miss. I'm a trained professional!" ... So I don't think I need things quite that high quality, yet anyway. So, basically I guess the question is - How crazy do you have to spend to get one that is actually effective? 'tanks! RonL.
