Question about Stadler Form Albert little

the part is great, needs no maintenance or has a removable air filter on the back - but it is made to be washed out. Once a year is enough.

You just have to take into account that if you don't work with the hose (we have it in the laundry room in the basement and the hose goes directly into the drain) then the water accumulates in the container and you have to empty it regularly, which is quite an effort because it fills up depending on the humidity (1x day for us) and then the device stops working. But you have that with EVERY dehumidifier.
