This unit is easy to clean and fill and has Air Washing pre-filter that reduces dust in your air. It also has 3 years limited warranty. One of the more notable features of this model is that it has two tanks. Two tanks makes carrying easier. The wheels on the unit make it a pleasure to move around.
Its design is probably not as pleasing as other models but most people use this unit for performance not looks. It does a great job and can humidify a large room with ease. The filters can be expensive to continue to replace but that is a small price to pay for the fact that the air quality is better in the room. It is relatively easy to refill and maintain the unit and the noise level are acceptable and to be expected in a humidifier.
