Product review (5 stars): Excellent replacement. Better than the original.
I purchased these based on the reviews and was actually impressed with how well made they are compared to the honeywell filters. Much more durable. I have been running my humidifier for the past 4 months 24/7 and it still puts out around 3 gallons of water a day. I am confident I will get a whole heating season out of one of these compared to using a couple of the name brand ones.
