Comparable to a cartridge system, but more effective peak

Attention to the choice of model for the same product is left with several different brands on Amazon (Elro, Duronic, etc ...) with substantial differences in prices, so compare prices before.
Pretty basic product, compact, easy to use (pressing On and go) with 500ml collector but stops automatically after 250ml.
Condensed water by thermoelectric effect: the air is sucked with the fan between two metal plates of different materials between which a circulating electrical current, the heating plates and the other is naturally cooled (electric Peltier effect). The air is thus heated and rapidly cooled, the temperature difference, causes the condensation of moisture on the cold plate (as in a window pane).
The vessel is closed with just a small hole for the drain which prevents setting of everywhere, and no risk of puddle around (you can put it on the carpet without risk)
Side efficiency is very correct, it can be compared to Rubson collectors cartridges, but with an "attack" more powerful if moisture peak (which will drop faster at first) because it draws in air, with the advantage of not having to constantly buy cartridges and the inconvenience of having to cut or turn on at the right time so do not to ensure permanent maintenance of control (when a cartridge collector is discreet and runs continuously).
The sound is low but enough to interfere impossible to let the night 24/24 if it is in a room (another advantage for cartridge systems).
It depends on the humidity level that you have to control. It is essential to buy a small hygrometer (available on Amazon for a few euros) to verify its effectiveness and turn it at the right time (humidity> 60/70%)
More moisture (condensation, mold> 70/80%) or temperature (> 30 ° C) will be more high efficiency make the difference, otherwise you will not see much. More air is cold and dry, the more effective will be small but that's normal, around 50/55% and below 20 ° C, hold ... and the product becomes inoperative to 40%.
It will take a good day to see the rate down to an acceptable level, for example 80% to 60% (20 ° C) if the source of moisture is not too pregnant, which is already not so bad because the cartridges can take days for the same work (nothing to do with big dehumidifiers dry them in 1 or 2 hours).
Namely an ideal indoor humidity is between 40 and 60% at 20 ° C, it should at least comply with minimum 30 to 70% but this also depends strongly on the temperature, the hotter it gets, the less moisture will tolerable because the air will contain more water vapor.
I have seen from experience that by measuring a rate beyond 65/70% humidity becomes tolerable evil and there I run in the morning and in the evening I stop device, it falls to 55% what is reasonable.
To reserve for small parts (no more than a dozen m2).
If you have rooms with very large problems (leaks), it will probably move to a higher capacity product, it is more suited to users who want to change cartridges to clean an average and more timely moisture (drying eg machine parts or north)
Small positive point, the 220V cable is long enough (1.50 m) therefore facilitates its installation.
