Product review (5 stars): Makes A Difference in Humidifier Efficiency
There's a noticeable difference when we use this in the humidifier vs. when we don't. When we do use it, the water filters through the humidifier much faster and more efficiently. When we skip a night, there's definitely more water left in the humidifier after a night of use. I think it will help lengthen the life of our humidifier filters, too, by keeping the water clean. Very happy with the product.
