While the E2441 may not have the advanced features of some other Boneco models, it is a reliable and efficient humidifier. The simple controls are easy to use and the top fill tank allows for easy filling without the need for lugging heavy tanks back and forth. You simply fill with a pitcher or cup, making it perfect for anyone that cannot carry large volumes of water. It is virtually silent and the evaporative wick is easy to access and replace. Simple, small and energy efficient, the Air O Swiss E2441 will keep your space amply humidified without breaking your bank.
