Medical Forum / Diseases and Disorders / Asthma / February 2005Yet Another Filter Question
? Does that little Oreck table top device generate ozone ? Dorothy ? ? Yes. The Oreck machine is a table top electronic air cleaner, (or, electrostatic precipitator, if you prefer). Same idea as what some folks put on their furnace. I carried them in my store for a a short while, but never sold any. Most of my customers have quite severe chemical problems, and the Oreck just adds to their problem. Oreck's excellent sales pitch didn't sound so good after I took a loss on these units. No matter how clean you keep the cell in these machines, you can smell the ozone from a few feet away. Definitely not recommended for any type of allergy, asthma, respiratory problem, or chemical sensitivity. Their only somewhat-saving grace is that they will chew up tobacco smoke pretty good. Basically, it's something to stay away from.

Smokers are no problem.................i shoot 'em on sight. Dorothy ? > Thanks so much Garth. > Smokers are no problem.................i shoot 'em on sight. > > Dorothy And thank you. I think we need more like you. SOBs using up our air............ shooting them is the perfect answer. Joy Pre-Filter: Fan draws in dirty air and air filter traps large particles such as hair, lint, etc. Ionizer: Electricity is used to positively charge small particles such as dust, smoke and pollen. Collector: A series of alternately charged collection plates attract and lock in dirt particles like a powerful magnet. Charcoal Odor Absorber: Activated charcoal absorbs common household odors. (replace periodically). Negative Ion Generator: Emits negative ions which help to freshen stale air. this are the component of that particular device....... the answer to table top is a BIG yes it produces OZONE , per EPA studies and other government agencies.....Ion produces a little bit of OZONE not as much as the OZONE GENERATOR but still produces OZONE....stay away from OZONE GENERATORS please. > Does that little Oreck table top device generate ozone ? > > Dorothy > Pre-Filter: > ?????

That's what that odour is that comes off ionizers; some hucksters refer to it as "fresh-outdoor-waterfall-lightning-uplifting" odour and say that that's a good thing. It's ozone. Granted, not much ozone, but, if you can smell it, it's bad for you. It's too bad the truth-in-advertising laws don't have decent teeth. If they did, outfits like Sharper Image, (and the other ionizer manufacturers), wouldn't be able to claim their machines are "air cleaners" or "air purifiers". Garth Allen, Ottawa, ON >>so let me ask , does purifiers like Sharper Image breeze give > [quoted text clipped - 14 lines] > ionizer manufacturers), wouldn't be able to claim their machines > are "air cleaners" or "air purifiers". Well, they are technically part of the well known class (mostly used in industry) of electrostatic dust precipitators (EDPs). They do remove small particles more efficiently than any other method (of cause, the amount of air that is being purified depends on the device spec, and in this case the troughput is not very large). And yes, they produce ozone. So they remove one polutant and introduce a little of another. Just like everything else in life, you have to chose from two evils. Regards, Evgenij > so let me ask , does purifiers like Sharper Image breeze give off ozone? They use corona discharge for 2 purposes 1) as means to blow air through the filters 2) to charge dust particles to cause their attraction to colelctor plates Anything that uses corona discharge is producing ozone, because it involves formation of plasma around the corona electrode. Specificaly Sharper Image devices probably produce more ozone than regular electrostatic dust precipitators (EDP), because later use the discharge only for 2) but not for 1) (to make them noiseless). Industrial EDPs are using fans to blow air through them - more noisy but less corona-discharge current needed. Now, I am sure Sharper Image made all possible optimizations to reduce amount of ozone produced, but it can never be completely eliminated. Regards, Evgenij > so let me ask , does purifiers like Sharper Image breeze give > off ozone? Yes, it does, and not only that but Sharper Image sued Consumer Reports for reporting on the bogus advertising done by Sharper Image and they ended up having to pay the $525,000 Consumer Reports incurred in defending themselves against libel. You can get more details here: http://www.msnbc.msn.com/id/6949993/ Thanks for everyones help, it saved me the cost of buying this product. I certainly don't want to add ozone to my room.
