This product is amazingly efficient. It took about five hours to fully charge (which is good in my experience, the longer the battery is charged the longer it will last before needing to be recharged and the longer the battery life will be as well). As soon as I pushed the button, it immediately started producing ozone. I've found that it's best to run it out of the room because the air will fill with O2 fairly quickly. Every time I saw that it stopped working, I moved it to another location and let it work. I've always liked air quality when it has a decent mix of ozone and the health benefits. are a plus, especially for my husband who has a lower autoimmune system than me. In addition, the air becomes cleaner and fresher.
