Product review (5 stars): Time and money saver
Has made a big difference in keeping our humidifier clean. Makes the filter last longer and saves us a lot of cleaning time and effort. We heat with wood and because that dries the air, we have to use a humidifier. Without Bacteriostat, the humidifer tank and especially the filters become dirty and require frequent cleaning and replacement. With this product we have no problem--we're very happy!
