Product review (3 stars): Extend Filter Life
Purchased an Essick 'MoistAIR' humidifier MA1201 in November 2011 at Home Depot and I have been extremely pleased with it. However, the MAF-1 Filter got moldy within less than four weeks. Home Depot did not carry replacement filters in the store and had to order three at $15.97 (plus tax) each online in order to get free shipping. I became annoyed at the projected cost of simple maintenance and decided to add a 1/6 bottle of Hydrogen Peroxide every time I fill the 1.9 gallon bottle (tank). It works. The second filter installed in December still looks like new after 5 months of operation!
