This is the second humidifier that we have purchased on this model. Easy to fill and we have had no problems with leaks. Resaonably quiet especially on the lower speeds. The best feature is its small footprint, fits into locations most units with this much capacity just cannot fit and it doesn't leave a white mineral dust all over the house. Buying replacement filters is not a problem and they are easy to change. If you need a humidifier I would highly recommend this unit.
