I bought the D510 model is the model below and has a slightly lower extraction capacities, and I am EXTREMELY satisfied! I use it for 4 months now and it gives me satisfaction: - In my small bathroom of 4m2 where I insufficient ventilation, it permtet avoid fog, and ambient water vapor and passed the relative humidity of 80% to about 55% in 2H. - In my room of 11 m2 where I condensation and mold problems (because my PVC window has no aerator, big mistake ...), this device has solved the problem: left running at night, he keeps a degree of humidity between 48 and 52% by adjusting the fan on low speed ... However, it's still quite noisy and probably well above the advertised 34dB (it's well over noise than a refrigerator with the compressor on ...) but as I sleep with ear plugs it does not bother me. At the performance level, it extracts one night between 1.5L and 1L of water depending on the temperature and humidity), so it works great ... Some caveats: - Integrated carrying handle is inconvenient, there is no "grip" so be careful not to drop the unit hands because shock may damage the compressor - LCD control panel is inconvenient because you have to squat to read and manipulate the buttons. Furthermore each press of a button emits a "beep" which is quite unpleasant, and you can not disable - No wheels for moving the unit, but despite its slightly higher weight (11 kg) and pognée impractical remains fairly easy to move, and suddenly it is very stable. Some tips to utilsiation: - VERY clean filters regularly !! Use a vacuum cleaner to suck dust from the filter screen, then remove it and also suck the HEPA filter, this at least 2 times a week ... And every month I advise to also remove the HEPA filter + coal and directly suck the gate of the compressor and cleaning the dirt that accumulate and then clean with a sponge and also to spend the screen filter in soapy water to clean it thoroughly. - TRIGGER ALARM FILTER (3 beeps every 30 min): in 4 months, Filter replacement alarm has already triggered 2 times, while the HEPA filter is not dirty at all ... In my opinion the trigger occurs after a predefined period of use ... Anyway, just in this case deactivate the alarm by pressing simultaneously for 2 seconds on the timer button and the "% "...
