Product review (4 stars): Filter Review with Water Recommendation
This filter works as well as the original. The cost was less than most sites and the delivery is quick.
I highly recommend that you use Reverse Osmosis (RO) water or De-Ionized (DI) water with your humidifier. They will greatly extend the life of the filter, because most of the filter clogging minerals are removed. RO water can be found at most convenience stores for 25 cents a gallon.
