Pros and cons

According to our dehumidifier expert
  • The carbon filter, the UV-C light, and the ionization function not only lower the humidity in the air, but also improve the air quality.
  • The dehumidifier is easy to move because it has wheels.
  • You get a condensation drain hose with the air purifier, so you can drain the condensed water continuously.
  • To drain the water, you always need to lead the condensation drain hose to a lower-level drain.

Description

With the Clean Air Optima CA-704, improve the air quality. That's because this dehumidifier and air purifier in one uses 4 filter technologies to improve the air quality: a pre-filter, a carbon filter, an ionizer, and a UV-C light. The carbon filter helps prevent odors, and the ionizer ensures that floating dust particles become heavier and land on the floor. In addition, the UV-C light keeps bacteria, fungi, and viruses from multiplying. To indicate the current humidity level, this dehumidifier uses a humidistat and a colored light ring. Red light means it's too humid, green indicates that the humidity is just right, and yellow means it's too dry.

It works but has some flaws

I've been using it for just a week now. Even though I have written a lot of negatives, I am not (yet) very dissatisfied with it. The product works but it does take some time. Contrary to other reviews, I don't find the sound really disturbing. You can hear him, but that also seems quite logical to me. It sounds a bit like a fan and has a monotonous sound. So even in the bedroom I prefer this noise to the noise of my neighbors. What is annoying is the bright blue light. This is disturbing in the bedroom. Even on standby it still gives a little blue light. What's also annoying is the beep it gives when it's full. He lets them hear every second instead of every minute, for example. It even does this in standby mode. So if you want to replace the container early, you have to pull the plug unless the beep doesn't bother you. The device has a humidity sensor. It would be nice if you could set it to turn on and off automatically depending on the humidity. Unfortunately this is not a possibility.
