Product review (4 stars): Venta replacement filter
I bought a Venta air humidifier in the Winter 2007/08 and we are very much satisfied with it. However, depending on the frequence you use it, you have to change from time to time the filter. As we are using it 24/7 in the heating period, it must be replaced all 2-3 month. Unfortunately, in the shop where we bought the air humidifier (bed, bath & beyond) we could not buy the filters anymore. But with Amazon we could get them and even much cheeper as in the shop and the filters were delivered within a few days
