Since I have 2 humidifiers and a CPAP machine, i go through a lot of distilled water. So i bought this distiller because i was tired of buying the water. This has been a great item to have, i use it almost every day (sometimes i dont have the time). Its almost paid for itself and i only bought this in early December. Its pretty easy to clean, it comes with a small container of citric acid. But i ordered a bigger package of citric acid when i ordered the distiller. The only noise with this, is the fan. Otherwise, its quiet. Would definitely recommend this item.
