A7K Ozone Generator by A2Z Ozone | Repeat Timer | Remote Control, Eliminating Odors in Homes, Cars, Large Rooms

This ozone generator is amazing. I've used an older ozone generator for about 25 years. Ozone generators are great for shock treatment of areas that have developed problems, especially mildewy smells. For example, I typically run an ozone generator in the basement one day in the spring and one day in the fall when the air is most prone to get musty. Or when I added a bunch of used books from a book sale to my home library and the air got a mildewy smell, I used an ozone generator and it took care of it. I've also used an ozone generator inside my car to take care of musty/mildewy smell, and even ran one inside my front-loading washer to get rid of the smell. In short, I've found an ozone generator to be a very effective way to treat musty, mildewy smells.So what's different about this A2Z A7K ozone generator? Power. With my old Panda ozone generator, I generally had to run the machine for several hours or overnight in a 15x15 foot room to really get an effective shock treatment. This A2Z model is much more powerful. I ran it for one hour in a 15x15 foot room and the result was better than running my old machine overnight. This thing puts out a lot of ozone. I also tried it an a more unusual application. When our furnace started running again this year, the air from the vents smelled musty. So I opened up the plenum in the basement, turned the A2Z ozone generator on, and set the furnace fan to run continuously for an hour. It did a surprisingly good job of freshening the whole house's ductwork in an hour. In fact, the generator produced enough ozone, even when distributed through the whole house, that I had to wait out the process on the front porch.This machine generates enough ozone concentration that you'll really want to seal off the room where you're using it, run the machine, then come back in and open a window for an hour before you open the room back up.One issue: When the machine's timer runs down, the fan keeps running. This creates the impression that the ozone generator is still running, but it's really just blowing air at that point, not making ozone. (I wonder whether this might be the reason that some users reported still having smells, even after running the generator for hours?) Personally, I wish the fan would shut off when the timer runs down, so that the unit shut down completely, but it's no big deal.Bottom line: This is a seriously powerful ozone generator, with a convenient timer and a powerful circulating fan. It's very effective at solving, not just masking, musty odors due to mildew.

Ok, first off I am giving this unit 5 stars based on the assumption that you are looking for an ozone generator. I am not giving ozone odor removal 5 stars.Pros:-Very sturdy metal case and good build quality.-One of the highest outputs available-Unit worked perfectly when I used it for 3 days in a row at 4 hours a day.-Output can be cut in half by only using one plate-Either plate can be turned on independently. Other units have reviews talking about a plate burning out or a plate that stops working due to it getting dirty. In this case you could only use the other plate, and still have the same output as most other models on the market.-Built in timer-RemoteCons:-The timer has set intervals of 30 mins, 1hr, 2hrs, or 4 hrs. I have seen people recommend running the units for much longer than 4 hours, and I could see wanting to run it for a shorter amount of time in a car or something small.-Remote is not as well built as the rest of the unit. The remote works fine, but it flimsy plastic. But most units don't have a remote, and I don't have any need for one.Other note: the repeat timer button will cycle the unit on and off on the interval set on the timer. If the timer is set to 2 hours, it will go on for two hours, off for two, on for two... It doesn't seem very helpful for anything I want to do, but it doesn't hurt that it is there.

Bought this 3 months ago since I have a lot of rental property. Haven't needed it until today. Opened the box to play with my new toy and it doesn't work...at all. Won't even power on. When you push the buttons on the front control panel, the lights that come on don't even correspond to the button being pushed. I would guess a bad control board. I hope someone from A2Z Ozone is following this. I am way past the Amazon return window so now I have to rely on them. Lesson learned...even if you aren't going to use it right away, open it and make sure it works!

Loved it for the first two weeks, but over the next two weeks...less and less O3 was producedInherited a house and several rentals that has bad odors. This worked on the first place and with each subsequent place...less and less soCould hear the corona arcing less and lessIf it continued to work like it did the first two week...I'd give a five star.Also purchased spare generators. Never opened them and also returned themReturned it and am very glad to be a Prime member

Si que genera una cantidad abundante de ozono en poco tiempo, mucho más rápido que los comunes que vemos en restaurantes en México

si bien genera ozono y de verdad elimina olores , se descompuso a la tercera semana de uso. El timer nunca funcionó bien .
