After we put a lot of time and energy in the evaluation of humidifiers, the Beurer LB 88 remained as our favorite also equal in the bedroom and living room. Basically, the device is very beautifully finished, the cleaning is easy by hand and the amount of water that is distributed in a very short time in the air, very impressive. One star deduction is available for the noise level and the super-bright blue LED lighting that really no need on this device. The lighting interferes with the use in the bedroom even more than the somewhat too high noise levels. It should be noted that none of the humidifier we tested had a lower noise level. So I guess that's just part.
The variable adjustment of the water quantity to be dispensed is a very great thing and help for every room to create a stable humidity. Even if the device eg: short turns from falling asleep within 30 minutes, a pleasant room climate is established (eg: our 15m² bedroom from 25% to 40% relative humidity in half less than one hour).
Be careful with really hard water. The evaporation surface is very small and with the supplied lime pads is two days a neat hard limestone crust to see the String should be removed immediately.
Conclusion: great device, we are happy to recommend.
