Product review (5 stars): Excellent Filter
After a months use of this product, I find the quality at least as good as that sold by Honeywell, and you get two of them for less than the price of just one Honeywell filter! I highly recommend this product. Just a couple words of advice to properly maintain whatever filter you use: 1) Flip it around every other filling of your humidifier tanks to keep it from over drying on the one end. 2) Use a water treatment solution to kill bacteria and prevent mineral buildup. I recommend Golden Solutions II. But note, you can get this for about half the price by buying it from Lowe's than by ordering through Amazon.
