A:AnswerThis model will require the same maintenance as your less expensive unit. The filter will need to be replaced every 6 months and vacuumed once a month. We do not have a life expectancy as it is an appliance. As long as it is properly used and cared for, the unit can last many years.
A:AnswerThis is not an oscillating unit. The air is brought in through the back of the unit and pushes out each side of the unit to ensure proper air circulation.
