Description

With your smartphone, you can also control the Clean Air Optima CA-604B Smart Top Filing when you're not at home. You can easily connect the humidifier to the app. The humidifier measures the humidity. When the humidity decreases, it turns on automatically. The device has a UV-C light. This light kills bacteria and viruses in the water. This means you humidify the air and purify it as well. Thanks to the built-in ionizer, dust particles and other undesired substances fall to the floor. The water tank has a 3.8L capacity. You can easily refill the tank via the top of the humidifier.

  • Unfortunately defective after 2 months of use

We were very satisfied with the product. Unfortunately this was short lived. The product has now been reported for repair as it keeps giving a message that the water tank is empty while this is not the case. Even after cleaning with original descaling agent. Assume this is bad luck. Once it does it works great and the difference in the room is definitely noticeable.
