What does exactly the plasma ionizer do? Does it produce ozone?

From my understanding it ionizes the air to attract dirt to it but creates an emf field. (Don't know how true it is)... I don't like high emf fields, so when in doubt, I pulled the purifier apart and unplugged the plasma.

artificially produced ozone is almost always made either by coronal discharge (electrical sparks) or short-wave ultra-violet (UV) light. This unit does make a sort of low, buzziing, staticy noise while in operation, but it also seems to have a sort of blue light inside, it could be either, I haven't taken it apart to see

I do own some ionizers, and as far as I can tell, this plasma wave technology is very different from an ionizer, but I don't know the physics to explain it. In practice, ionizers make my eyes and nose and throat smart if they are on in a room for more than an hour or so. This unit does not have that effect whatsoever. It just breaks down odors. Otherwise I notice nothing. I have two of them and have been happy with them for years.....

Supposedly the "negative ions" produced by the Truman Cell (I think?) actually reduce Ozone, according to some of the company info I read today. It even says that since the negative ions cause dust to be "heavier", not to arrange the air purifier in such a way that it draws the room air over you while sleeping. Presumably the heavier particles it's trying to capture, will land on you and you'll be breathing in the dust and pollen, etc before the Truman Cell can get them. Sounds good to me. And the air does have a weirdly fresh odor, to me. My DH, on the other hand, "don't smell anything!". (which is the whole point.)

It has an ionizer, but you can choose to use it or not. I'd have to check again, but it seems like it said that it doesn't ionize the air. When I turn on the ionizer, I do not notice any effects as from ionization. I have COPD and Apnea, and ionized air, is supposed to cause problems with those things.

Some air cleaners use ozone. However, this air purifier uses a filter. The only way that it can yield ozone is if there was an electrical problem causing arcing. I would say that all electrical products run this extremely low risk, and it has nothing to do with the air filtering functionality of this particular product. Also, if there was arcing, my feeling is that hazard due to ozone is the least of your concerns. Fire would be a real risk.

"All of our air purifiers have been tested to comply within the ozone safety requirements set forth by California Air Resources Board. Our BioGS model emits zero ozone when the negative ion generator is on or off and our MinusA2 emits zero ozone on all speeds once you have turned off the Negative Ion Generator. An amount of 0.002 ppm (parts-per-million) was recorded at low fan speed of our MinusA2 with the negative ionizer turned on. That is 25 times less than the 0.05 ppm maximum ozone concentration safety standard set forth by the California Air Resources Board." - http://www.rabbitair.com/faq.aspx

I am.not sure of the exact info, but we set it to 68 and let it run, we hardly notice an increase in the electric bill, during the warmest months an increase of about $10 is avg. I dont not think it has an air ionizer. Hope this helps

Don't know about the ionizer, bought it for a friend and she loves the unit.

If you believe the company's claim that it is not an ozone generator then I believe it appears to be a hydrogen peroxide generator. See my comment to the question here about what technology does this use. I explain in more detail including safety.

It shuts off when it reaches its desired temperature. It could possibly turn off if it starts to overheat. But, that has never happened to mine that I know of. Sorry, but I am not sure about the ionizer question. I am very happy with mine.

No, it does not generate ozone when the Plasmacluster ion function switch is on. I have had the unit running constantly since I purchased it a few months ago & not smelled anything.

I called the company directly, was transferred to an overseas operator, who said it does produce ozone at 5ppb. 50ppb is the maximum recommended by ??? (she was kind of vague on that one). i wonder whether they understand the technology or all the different emission standards we have here ...

I bought this item a long time ago and i really don't remember about the ionization feature. I don't think I ever used it. I bought it for a humidifier and it was fine for that.

Absolutely. I would not use an ionizer and I turned mine off. Very easy to do! Just press one button. On the front of the unit, there are various buttons with lights underneath. The Very bottom button looks like a star (?) If this is lit blue, the ionizer is on. To turn it off, press and hold the button until the light goes off (this take a few seconds). Good to go, without ions.

Yes, you can turn off the ionizer. In fact, I don't use it. The air winds up smelling like clean air, not like some awful air freshener spray. I use the heavy-duty charcoal filters, which are especially good at removing smoke and odors. They cost more, but I think they are worth the price for people who are sensitive or allergic.

Because ionisers emit ozone. Ozone can be good for the air, but in actuality, ozone emissions can be extremely harmful to us. I've done TONS of research on ionic filters and what i've found shocked me! Repeated exposure to ion emissions can cause a myriad of health problems, including but not limited to; Resperitory problems as well as eye and nose irritation.
