Timer
When you want to run an ozone air purifier at a high level for a short period of time, in order to remove a strong odor you'll either have to remember to turn it off -- or use a purifier with a timer. With the XJ-3000C Air Purifier, when you need to treat a space with a strong level of ozone for 1, 2, or 4 hours while you're gone, simply use the built-in timer. The XJ-3000C will automatically turn off after the specified amount of time with no further intervention from you.
