Product review (1 stars): The are NOT OEM pads and do not work nearly as well
These are not OEM pads, they are the cheap-o replacement pads. I gave them a try (to save money) and I regret it. When I use these pads the humidifier can not humidify the house adequately.

I believe the problem is the foam that they are made from. The holes are too small/tight and the air does NOT flow through them. That means they are very inefficient.

I am very unhappy with these filters and will never buy them again. Since I bought 4 of them I will also end up throwing away three of them. Learn from my mistake!
