Product review (2 stars): Disappointed customer
The plastic housing for the replacement filter disintergrates when washed. When the filter dries, it becomes very hard. This is ineffective as the dial on the humidifier registers that this new replacement needs changing and this filter needs constant changing. The new extra replacement filters (2) that were purchased 6 weeks ago have almost doubled in price since that purchase. The humidifier should be sold with multiple filters and now becomes a bad investment. We do not recommend this purchase.
