does this unit produce OZONE? this is why sharper image shut down. many people got cancer from the excess of ozone produced by the ionizers. At h

Yes it produces ozone but not in high concentration . otherwise we could have coped with global warming by using these fans . LOL You can google more and let me know too. I uses this feature rarely when i feel there is dust around to ionize it and settle it down.

First of all: you do not want a lot of ozone production. Ozone (at best) is a respiratory irritant and can have serious health effects if exposure and "dose" are long and heavy. Second, I too found that, even after a few months - there was little build up on ANY part of the filtration system in this unit. It is not on the Consumers Report List of approved air purifiers, either. At least - I looked and couldn't find it. I have a little larger Honeywell unit which absolutely has a higher rate of air volume. But its filters don't show much build up either. - The dust build up is more noticeable on the Honeywell unit than the Mountain Air unit after about six months though. I've taken to running both together in a bedroom just on the idea of applying some "overkill" because both units are rated for larger floor area. The ozone output I keep at about 25% of max and sometimes i turn it off completely.

Yes, all UV-C products produce dangerous amounts of ozone! See:http://www.newton.dep.anl.gov/askasci/chem03/chem03323.htm

Ozone is toxic to breathe. Just how much is debatable but in my opinion it would be much better to run your machine when you are not home.

I have well water and a softener, and high iron content. I purchased this product about a year ago, and it worked great for a few weeks (strong ozone smell). Then the ozone smell stopped. I sent it back to greentech environmental and they replaced it free of charge. Then the same problem occurred. They recommended I "backwash" the unit, where you reverse the connections, and flow water backwards. This fixed the problem! Apparently small particles can clog the ozone generator. Now I backflush the unit after every 4 loads (once a week), and that has worked over the past 9 months. Also am using a smaller (1 micron) sediment filter, instead of 30 micron, ahead of the softener.

I'm no scientist but amount of ozone that is generated by a plasma device such as this is minimal but some people are more sensitive. If your looking remove odor I had great results with an ozone generator to remove smoke or other offensive odors permanently. I always put pets outside, leave for a couple hours, turn it off, and find some entertainment for a few hours before I return.

Yes. Just press & hold the ionizer button for a few seconds and it will shut off. We leave the ionizer off all the time.

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.)

Not sure what your asking. The unit shown here is a salt water generator which converts salt to chlorine and an ozone generator which adds ozone. It works great. Have not touched my water in nearly a year. Still crystal clear.

Ozone generators work by electrically charging oxygen (o2) and converting it into ozone (o3). One of the big advantages of this product is that it it doesn't run constantly. By turning itself off it saves on wear and tear. Thanks.

I was not completely sure about the answer to this, so I did a little research. From what I could find, it emits 1 part/billion, but that all electronics do emit some ozone, and that anything under 80 parts/billion is safe. I hope this info was helpful - if not, I'd say try contacting Therapure Customer Service directly.

Don't know anything about the effects of the ionizer feature. Sorry! Using the ionizer feature is optional, though. You can choose to have it on or off.

From what I researched, it only generates ozone through the ionizer feature. I don't turn that part on.

because of the quality of the unit it may produce too much ozone in a space smaller than 500 sq ft. An over abundance of ozone can lead to headaches and a cough. If you have a space that is 500 sq feet with an open door leading to a basement or to an upper level you may be okay. But if the 500 sq. ft. area is closed off it may be a concern and you will detect the stronger concentration of ozone when you walk in to the area.

Depending upon the desired temperature setting, this heater will shut down when that temp is reached. The ionizer - forget the scientific or pseudo scientific explanation - will help to remove unwanted odors from the room in which you have placed the heater. You might not notice it, so in that case, don't bother with it. I like to use it in our "wet dog" room which is not well ventilated but I most certainly don't hit the ION button every time I turn on this heater. Since I had an ionizer setting on a fan and was delighted with it - no I didn't notice an odor from its use.

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.

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.
