Product review (3 stars): They stay in place better and don't fall over
Although these are priced lower than the Vicks brand, they are the same and don't seem to last more than 3-4 months. What I do when they get a little mushy is to use 2 of them together. I just squeeze them to make sure that they fit. They stay in place better and don't fall over. Use filtered water, and every time I fill the reservoir I reverse the filters to make sure they are wet all the way to the top. I use the humidifier all winter long, 24 hours a day, to keep the humidity level as close to 50% as possible. You have to handle them carefully or you can rip the fabric which is why I only give them 3 stars, along with the price. They shouldn't cost that much for what your getting. Also the filters that have the metal in them (to help them stay up and straight) are a little better.
