Twin Air Pro Negative ion generator / ionizer

I have purchased two of these units and am delighted with them so far. Over the past two decades, I’ve tried various ionizers. In the late 80s and early 90s there was at least one company manufacturing impressive ionizers, but since then it has been a series of disappointments, with the last ionizer I purchased breaking the first time I depressed the On switch. The one before that lasted about a month. Both of these were desktop units that are still available and considered top-line units. After that second unit broke out of the box I opened it up out of curiosity to discover two or three wires secured to the inside of the case with what looked like lumps of clay and some electrical tape. It was a $90 piece of junk.That is why I’m so pleased with what NaturAir has accomplished. These are heavy-duty, solid-state negative ionizers with no moving parts, the output of which you can feel several feet away. They are very powerful and seem to be made with impeccable craftsmanship. My objective in using these is principally to improve the indoor air quality and reduce the amount of dust in the house. But I’m also aware of the potential health benefits of negative ionization. Although it is subjective, I do feel I am sleeping better when I use an ionizer in the bedroom. It’s too soon to tell, but there has been, at last so far, a reduction in the number of headaches I typically experience during this time of year. If NaturAir had decided to produce ionizers only half as impressive as they did, they would have been superior to much of what is currently on the market, but they went all in and are producing masterpieces. These units are far and above even the good units I remember from the early 90s.I’m personally grateful to this company, because I was beginning to believe that quality negative ion generators would probably not be affordably produced again in the United States. (I say “United States” because I’ve heard anecdotally that Japan takes negative ionization seriously and produces good generators).

It worked for about 7 months, then, just quit. No reason for it to just quit. It wasn't moved. One day I noticed that the light was not on. Then, I checked with the hair on my arm to see if I could feel an electric charge. Nothing. Just a big ugly paperweight now. That's a lot of money to spend on just a few months of clean air. When it worked, it worked well.

Unit stopped working today. It was putting out alot of ions. I tested it with my ion tester....I havent even had it a week and it stopped working...returning...UPDATE(09-01)...customer contacted me and sent out a new unit. The new unit is working now. It def gives out a ton of negative ions. I hope this one keeps working. I'm upgrading to 3 stars for the excellent customer service. I will update in a month on the product.....Update....a month later unit is still working good. I'm not sure if I've experienced any health benefits or not. My finance was still getting stuffed up while sitting on the couch. She is allergic to dogs and we have 2 boxers, so I'm not sure if this thing working or not. She hasn't been stuffy in a few days tho, so maybe it just takes a little time to start feeling the effects. I will update in another month.

The media could not be loaded. The Pro model poured out the negative ions upon arrival and for the first two weeks, I was extremely pleased. Then, this morning, I tested the ion output as I usually do and where I usually see a steadily brightly glowing bulb indicating lots of emitting negative ions from in front of the two large heads, behind them, and yes, even from the bottom of the unit, this morning, the tester barely blinked at all as you can see from the video that I attached. I have another negative ion emitter in my bedroom and tested that unit to be sure the tester was working and it glowed brightly, even though the negative ion unit in my bedroom is much, much less powerful and less expensive. For the cost of this unit, I would expect it to work longer than two or so weeks. I posted the video because I fully expect the seller to respond by stating that they tested the unit upon its return and it worked "perfectly". I wanted you to see for yourself. The negative ion output went from powerful to truly pitiful. As a comparison, I am attaching a photo of the negative ion tester from the other room glowing away from the much less powerful unit to show that the tester worked perfectly. Unfortunately, Amazon only permits one video upload or I would have uploaded a video of that result, too instead of just a photo. (Please excuse the mild shaking in the video but I have some Parkinson’s Disease and cannot help it.)

I like the product a lot. Minus one star, because I had to return the first unit when it failed after 4 months. The company replaced it, provided great service and paid the return shipping.I won't leave the unit on 24/7, to extend the life, but it does have a lot of power.
