Review: Better than expected! Both the GT50 and Seller!!!! - I have had my GT50s for several weeks and now feel confident in their operation to be able to write what I hope is a useful comment. Bottom line up front - These are high quality units that seem to do every thing that is claimed of them well. I have not found any competition for twice the price in my searches. So, if you need an air purifier for a small space, look no further than the GT50. I would recommend that you buy them from The Green Giraffe. I have not dealt with a company more interested in making sure that the customer was happy and the product did what it was expected to do! In my experience and having lived all over the world I have never received more concern than from The Green Giraffe! I would rate them 5 stars! More if I could.... I had two problems that I had hoped to solve. We have a cat and her box is in our bathroom. Although it is kept clean, there are times it doesn't smell that way. The other was in my office at the university. Both areas are larger than the 50 sq. feet that the GT50 is designed to deal with. So, I began searching the Internet and began my research. I had read about a larger system on Dr. Mercola's site and looked on other sites where I had previously bought a purifier. I found a review on the GreenTech GT3000 and it looked a lot like the one that was so well recommended on Dr Mercola's site. It met the requirements what I wanted, but was designed for a larger area than those that I needed to purify. So, another search on GreenTech found the GT50. It sounded perfect for the task and it was only $50! So, I ordered two! They arrived 2 days later and I installed the first one in the bathroom. Within minutes of being turned on the air smelled fresh and clean! I did adjust the output to get the most benefit without any ozone odor. The next day I took the other one to work and it worked just as well in making the air smell clean! It seemed to give me increased energy as well. I did comment on the merchant feedback that I was very happy with the GT50s, but that they were louder than I had expected from previous customer comments that they were silent. It is not that they are loud, but that they were not silent. They sounded like they had a small fan inside which you can hear from as much as 10 feet away if it is quiet and if you are listening for it. I was surprised the next day to receive an email from the owner of The Green Giraffe who was concerned with the sound and asked if I would call her. I called and we had a very useful conversation about the sound and her worries that the product was not operating correctly. She was sufficiently concerned to immediately send out two new units and return label information for the two that I had. They arrived the very next day!!! I replaced the one in the bathroom and monitored it. It made the same sounds as the one it replaced... a quiet not objectionable fan noise. I called her with this news and said that I thought that there was a fan inside, thus the noise was not a problem. In fact, I asked her if I could keep the first two and pay for the new ones that she had already sent. That was arranged and now I have four! The owner wrote the next day and said that she had contacted the manufacturer of the GT50 and they had confirmed that there was in fact a fan in the unit. Again she went far beyond any merchant would normally go to investigate a problem due to her concern with wanting to provide a quality product and customer experience! One of the new GT50s went in my son's room that despite cleaning the carpet still had the faint smell of cigarette smoke from previous owners of our home. Although this room is almost 8 times larger than the stated capacity of the GT50 it smelled clean and smoke free by the next morning! The other was installed in the kitchen that is also much larger than the 50 sq. feet served by the GT50. The result is excellent! I will close this "book" by reiterating that the GT50 is everything claimed of it so far and that there is no better place to buy it than from The Green Giraffe! No... they didn't pay me to write this!
Review: It's cranking out Ozone for sure - The GT50's method of generating negative ions is through coronal discharge that is generating Ozone and Nitric Oxides. So it's really and O3 generator and not strictly a negative ion generator. They don't market it this way as Ozone has bad press. The GT50 generates very small amounts that are safe. Ozone is, however, dangerous in higher concentrations. I'm in a 3,000 plus square foot house. I plugged it in the bathroom on the main floor and within 15 mins. I could smell Ozone half way across the house. That's pretty impressive for this little thing. Most people can detect Ozone in concentrations as little as 10 parts per billion. So it must be at least that strong where I'm sitting. If you can smell Ozone - you're cleaning the air. The extra Oxygen is cracking off and reacting with anything it can. This includes odors, bacteria, viruses, and anything and everything else that will oxidize. Even the pigment in the ink in photographs on your walls. Don't worry, we are talking very small amounts here. (Should you ever buy a commercial grade Ozone generator - used in fire restorations - you'd be surprised what you can destroy besides odors.) It would be difficult to build up a high concentration with what the GT50 is putting out. Under normal conditions, Ozone has a half-life of about 30 mins. The negative ions are cleaning the air as well. The will attach to positively charged particles and then be pulled to your positively charged floors or even walls. You will eventually vacuum that up. In any case, it's out of the air and you're not breathing it. The GT50 does make a hissing noise. That noise is the coronal discharge and fan noise combined. It's not loud or objectionable (at least my two are not). It has a light on it which makes a great night light - especially having these things placed in the bathrooms. They do need to be cleaned once a month, but cleaning them is very easy. I'm happy enough with the two I bought that I just ordered another two for the other bathrooms. They do seem to be well made. I just hope they last long enough that I'll feel like I got my 50 bucks worth. Lastly, they will keep your bathrooms smelling fresh. Space several through out your house and the whole house is going to be smelling fresh.

### ⭐ Consider the hazards before buying this product!
*by A***E on February 3, 2012*

I was excited once this product arrived so plugged it in right away on med-low setting, waited, and took in a BIG breath of this "purifying air"... and became light headed. I did some research and became frightened, so I returned it. I highly recommend those interested in buying this product to review the governments Air Resource Board before purchasing. "Not all air-cleaning devices are appropriate for home use -- some can be harmful to human health. The ARB recommends that ozone generators, air cleaners that intentionally produce ozone, not be used in the home. Ozone is a gas that can cause health problems, including respiratory tract irritation and breathing difficulty (Ozone and Health). In response to legislation, Assembly Bill 2276 (2006, Pavley), the ARB has adopted a regulation to limit the ozone emissions from indoor air cleaning devices. For more information on the regulation, please visit: (Air Cleaner Regulation Webpage link that Amazon won't let me insert)" - California Environmental Protection Agency, Air Resources Board. Consider getting a purifier on this list like I did: CALIFORNIA CERTIFIED AIR CLEANERS: (also failed link, sorry) ----------------EPA's Fact Sheet - Ozone Generators March 2006 ------------------- //Why are ozone generators still on the market? If ozone generators are ineffective at removing air pollutants, and they pose major health risks to users, why do they continue to be sold? The unfortunate answer is that misleading advertising by manufacturers is very effective, and no government agency has the authority to fully regulate these devices. Thus, ARB is actively working to educate professionals and the public about the dangers of using ozone generators. //What are the adverse health effects from exposure to ozone? Buyers of ozone generators may not be aware that ozone can harm the cells in the lungs and respiratory airways. Exposure to ozone irritates and inflames the lining of the respiratory system. It causes symptoms including coughing, chest tightness, and shortness of breath. In persons with asthma, ozone can worsen asthma symptoms, and one study indicates that ozone may contribute to the development of asthma. Ozone impairs breathing. Elevated exposures to ozone can cause permanent lung damage, and repeated exposure can even increase the risk of dying among persons already in poor health. Persons especially vulnerable include children and those who suffer from asthma or other respiratory diseases, including the elderly. Due to the health hazards of ozone, California has worked aggressively for decades to reduce outdoor ozone levels, with considerable success. For more information on the health effects of ozone, visit [...] In addition to its impacts on health, ozone can also damage materials such as rubber, fabrics, plastics and other indoor furnishings.
