Product review (5 stars): Here's the funny part though
We have well water, so the filters get hardened in several weeks. So when that happens, and the humidifier doesn't move as much water, I remove the hardened one and place it in a ziploc bag, add a couple ounces of white vinegar, and fill the rest with water, and let it soak overnight. This removes the deposits, and I leave it (wet) in the ziploc bag. Meanwhile, I have replaced the filter with one I had already cleaned by above procedure. Rotating between two filters, I get around 3 months per filter. Here's the funny part though. the first filter to give out was the original Honeywell filter. The first replacement filter is still going strong. So that is the reason for the 5-star rating. It moves just as much water as the Honeywell filter, and lasts longer.
