Pick the right InnoGear, this one is powerful. [SEP] If you are looking for an intermittent one then pick gen 2, it will last into the entire night when you sleep. But if you are looking for something more powerful to deodorize your room quickly, then this is the one you want. It does not have an intermittent every 30 seconds mist power, instead it either blasts fully or 70%, in no time your room will smell amazing. I do caution you due to its powerful misting ability, it can cause some dampness from the mist so please make sure it is placed somewhere water from the mist won't damage your property or use something that can'tdampen your furniture.
