Product review (2 stars): Waste of time and money
At first, this filter worked great. But in time it became useless. Once you start the cleaning habit, it goes downhill rapidly. It very easily comes apart even if you try to handle it carefully. I have a baby to tend to. I don't have time to nurture the delicate needs of a filter of all things! It is worth my money to buy the disposables to ensure the efficient operation of my humidifiers to keep my kids healthier. Sorry, but there is nothing permanent about this filter except that it is permanently out of our home.
