I think I love this thing! I bought it on whim and I think it's actually making a difference for me. I've read the warnings about ionic air purifiers creating "soot" when they're working well, so for that reason (and others) I don't leave it on all the time.

I have read studies about negative ions helping with depression. I have not felt depressed since I got this. If you can afford to take a gamble on negative ions, this one seems to be the right choice. Others do not create enough ions at the levels that get consistently good results. When the plastic is around the antenna, the sensor indicates no ions. When I take it off, it detects ions. So ions are being generated. Is it as many as claimed? Who knows? But the scientists who ran these tests used the same specs as this product, so it is worth the gamble in my eyes. Certainly as worthwhile as medicating for depression, which I also do. It also helps clean the air. Maybe the 2 are related. Or maybe ECT works because it cancels positive ions in toxins in our brains and we can get that effect from just putting these negative ions in the air. I put mine next to the intake of my cpap all night so I am pumping negative oxygen ions up my nose all night. The experiments indicate that it does not matter how many nights you do this, which may suggest that positive ions could be trapped in the brain and can be reset with a healing effect that lasts many days or longer. It does feel right to me that depression could partly be a lack of electrons, blocking the movement of some signals in the brain with some stubborn positively charged toxins like air pollution. It does feel toxic and blocked to be depressed.

It's a very old-school device and, of course, produces a little bit of ozone. But on the upside, it's much cheaper than the Ion Trading Japan MI-1000-S and produces a much stronger ionic wind (compared it myself) and doesn't smell like cheap plastic. On the downside, it appears that the emitter antenna here would be harder to clean than the emitter 'needles' of the MI. Tip: Don't leave your phone near it for too long. I did and some pixels of my OLED screen started to act up. The problem went away after keeping my phone away from the device for some time. This happened twice and has never happened before with my screen, so I'm pretty sure of the correlation.

I had to return two of these items, eventually opting for a refund rather than replacement. I had a great negative ion generator from a now defunct small business that finally died after almost a decade of service but shared a similar design to this device. Good news is it really pumps out the negative ions, but regrettably both units stopped functioning. The first stopped working within the day, the second lasted nearly a month before kicking the bucket. I really wanted this to work, but company has some serious quality control issues they need to resolve.

I am always skeptical when people insist that a product has a profound effect of any kind. Well, here I am, about to write a review to say I have noticed a profound effect! We have usually used two Ionizers to clean the air in our home. One died, so I did some research only to find that the ozone created is not especially good for you. I was shocked, we love that smell. I decided to try this negative ion generator. I expected it to clean the air. It did, and more. On the second day, I realized I was no longer rubbing my eyes in the evening, and ending up using drops to relief the tiredness and itching. I used to keep the eyedrops in the living room with me because I knew I would need them every day. Well, those drops are back in the medicine cabinet, where I believe they will stay until I have to throw them out because they have expired. A profound effect, indeed.

This negative ion emitter has been cleaning the air in my friend's LA house for the last two years. She has lung issues and she loves this machine. Now that I have my own Wein Vortex VI-3500 ROOM IONIC AIR PURIFIER I too am enjoying the fresh air it creates. I'm going to be buying a second one soon since it is so light & portable and keeps the air fresh. I thought there would be a plastic smell to it when I opened the box, but nope, no smell.

I have one of these in my bedroom and I bought one for my boyfriend and am amazed at how well they work. I bought this one for a good friend that has terrible sinus problems- I’m hopeful it will help her.

This is advertised as one of the strongest room ionizers on the market. Unless something has changed in regards to regulations or what ionizers are allowed to put out volume wise, I find this product to be very weak. I bought a negative ionizer back in the 80's that literally, if you turned it up high would create a room full of static electricity and serious dust as particles fell from the air. It was metal (this one is plastic) and a quarter the size. Perhaps it is because I live in Florida with high humidity and low dust particles, or perhaps with so many more electronics now with computers and phones these ionizers can no longer produce that high of ionization without damaging them, but compared to what I bought almost 40 years ago, this is a way inferior product; at roughly the same price. I have very little dust evidence that it is doing its job or notice much of a difference in air quality. Thinking of sending it back. Hard to believe this is the strongest ionizer on the market today.
