Product review (1 stars): Not worth the money...even though they cost less.
I bought these mostly because they are approved for use in my humidifier, and the cost is much better than others I've purchased. It was a waste of money. They are the worst replacement filters I've purchased, making them MORE costly because I'll have to replace them sooner. The first one became dry and discolored within one week (24/7 use) of placing it in the humidifier (with name brand and other filters, it usually takes about 2 months of 24/7 use for this to happen. The filter also had an odor develop within the same time period, and it started "collapsing" so that it didn't function properly inside the humidifier. I am very disappointed, particularly since I discovered this just days after my 30 day return period with Amazon.com passed. I won't buy these again. I should add these were used in the Honeywell Germ Free Cool Mist Humidifier.
