Product review (3 stars): filters
Works okay, but the price it higher than desired. I am looking for alternative ways to humidify without continued filter replacements. We tried the ultrasonic humidifier and they put out a white dust over everything in the house. So back to the filters. The ultrasonic requires distilled water or water without the minerals(the white dust). Buying the distilled water is worse than buying filters. We try to buy things which are maintenance free (we are lazy, but we would like to think it is because we don't want to add to the planets pollution). We dispose of plastic water bottles, or filters, or the packages (not good for our environment).
