I only use batterys and never the AC adapter. This will allow the unit to clean itself internally under full power. Everything is fine and we love the water. We are moving in about 2 months which means I will have to un-plug the unit. This is why I purchased, from someone else, an ozone generator but it does'nt seem to work when there is smoke in the air.
Cigarette smoke is a complicated air pollutant.
Nicotine is not a gas and Ozone DOES NOT directly react with or break-down nicotine. Only the odor caused by nicotine reacts with Ozone. Ozone attacks the odors created by smoke particles. Ozones main benefit is to de-odorize a room after the smoke has cleared. Afterwards, the room does'nt smell like an ash tray.
