Product review (5 stars): BestAir Humidifier 3BT-6 Treatment
We bought this item at the start of cold weather in SE Kansas (Nov 1).  We usually had the wick last 3 - 4 weeks before replacing at a cost of around $10.00 which translates to a cost of $70.00 for the cols weather season our house is 2300 square feet.  We run 2 humidifiers.  With this item we are still on our 1st set of filters (March 5th) and they are still going strong no odor or algee build up.  This is a great product and a huge saving for any humidifier beand both ours are Sunbeams.
