Second Chance Clean Air Optima CA-703

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.
