Review on Digital Generator Purifier Capacity Purifies by Heather White

What keeps ozone generators away from most people is just the price (my largest ozone generator is around $280), but this one costs well under $150 and gives you a nice digital display (always a plus ) and features selectable fan speed and ozone output settings, as well as a timer and cycle mode that runs every 12 or 24 hours. It's hard to argue with such a compact and surprisingly powerful (10,000mg/h) device that has all the display and timer settings for this price point. Most people don't need an industrial setup. Most people need one per room and this small unit is perfect. It's pretty quiet, unless you turn it on at full power there will be good sound. And even on the lowest level, it produces enough ozone. I've always liked the smell of ozone and am not sensitive to it. Some people are very careful with the ozone generator and you should not operate it in a busy room or be in a room with it while it is running. I ran it to test ozone performance and I can confirm that it does indeed work. Very good result. The only problem (and a small one) is that the instructions say how to work with it and mention a removable filter but never say how to remove or clean it. It's really just a wire mesh pre-filter held in place by a plastic cage on the back. To remove it, simply pry up the cage on the back, exposing the pre-filter. If you're using this in a dusty environment (which you really shouldn't be doing) you might want to buy some oven filter material and put it on the air intake. The supplied screen "Filter" removes some particles, but not much. My other small ozone generator has the same pre-filter setting. Only my very expensive unit has a HEPA filter, so if you want to upgrade to something that releases ozone and filters the air, look at the more expensive models. I am very happy with it and consider it a very well working and powerful ozone generator for the money. $130 is a steal for this, and the feature set makes it a no-brainer.
