Green Air Deluxe 2 Plate HEPA and Odor Fighting Filter Air Purifier Ozone Generator

5 stars all around on this product. This is a handsome, well made unit that looks very elegant in any corner of a room. Years ago, I had an Alpine filter that made me remember how good these units are. All the hysteria about ozone generation is ridiculous, and it's not dangerous at all if used according to the instructions. It's important to place the unit as high up and near to a return a/c vent as possible to get maximum coverage. It's hard to believe a unit this size will cover the area it advertises but it absolutely will. It is incredibly efficient. To give you an idea of how efficient this thing is, I can cook bacon and sausage in a cast iron skillet and smoke my kitchen up. I turn the unit ozone generator on stage II and a high fan speed and within 15 minutes, all the smell and smoke in my entire house is cleared out and my home smells fresh again. It's that powerful. I like the timer functions on the unit and the ozone generator. I have mine set to come on about two hours before I come home from work and shut off before I get there. To be totally objective, there's two things I wish this unit would improve on: 1. I wish there were a way to dim the unit LED lights or turn them off entirely because they are pretty bright in a dark room. 2. I wish the fan was quieter. On high speed (which I don't use often at all), it's pretty loud. If you like white noise, this will be right up your alley. If loud fans bother you, it might be too much. However, you don't use it on high very often so it's not that big of an issue as far as I'm concerned. If the unit is on high, I'm using to to clear out the house for a short period of time. The unit is pretty heavy, comes well packed, and the instructions are pretty straightforward. Even with the improvements I suggested on the unit, this is still a five star purchase. It will do exactly what it says it will and then some. If you're looking for a way to really improve the air quality by means of 4 stage filtration and ozone generation, this is the unit to get. I couldn't be happier. Read more

29 Jan 23 update - just received and installed a replacement control board, the original had failed. Customer service responded to my request in minutes, and sent me a new part (I volunteered to fix it myself) which I received within a week of my reported problem. I’m very involved in customer service myself, and I have to say this manufacturer is on top of their game, but in quality and service. Original review: I was involved in Ecoquest’s MLM some years ago, so I have some familiarity with the technology involved with this air purifier. Without getting into terminology and shop talk, this unit is solid, highly functional, and very powerful. It is an ozone generator, so if you believe that ozone is bad for you, stay away from this one. However, if you have found the purification and odor control benefits of ozone, this is a very good investment. Fan is a little loud at high speeds, but no more than I would expect. I had the fan motor go bad after 10 months, and when I contacted the manufacturer through Amazon, they responded within minutes. They gave me the choice of sending the unit back to them, or sending the motor to me to repair myself. I chose the latter (having some experience with this kind of repair), and the motor arrived within 3 days, at no cost, with easy to follow instructions. To sum it up, this is a great machine, and the manufacturer is supportive of their customers concerns. Absolutely worth my money. Read more

So far so good. I bought this because my girl was having allergy problems relating to my animals. I had other air purifiers n the past, nice ones, but none of them allowed me to set specific time on when to turn on and off. They really only had timers specifying how long to run. The problem was, I she had to be home to push to button to turn it on. We got this and PROBLEM SOLVED. Now, we can set this item to turn on before she gets home and the air is clean before she walks in. I could not be happier. It has definitely made a difference in the air quality. We run it for a few hours a day and she has stopped sniffling, sneezing, and coughing. As far as noise, it CAN BE noisy if you have it turned all the way up. I am not sure what you would expect if you using such a powerful machine, but it can run quietly too on a lower setting. We have in the room where we watch TV and with it being on a medium setting, we don't even notice it anymore. Read more

It is a good unit. It can put out an abundance of O3. Everything works. It does need two things: 1. More control of fan speed. There are 4 speeds but even the calmest one is too strong and way too loud. 2. More control of the ozone level. Even the weakest one puts out too much unless the room is quite large. Our bedroom is 20 x 12 feet. I think I can remove an ozone plate and that might be a solution. If the maker would fix the fan noise problem, perhaps by adding a fifth speed that is whisper quiet, they would have a unit with more appeal. As it is now, the fan is too load for a bedroom or living room unless they are quite large. Read more
