Product review (2 stars): Bad design
There is one thing that drives me crazy about the design of this. It does not stand up and instead flops all over the place, which makes me wonder if it is even effective for filtering. Plus, it needs to be replaced often because it eventually lies down and becomes impossible to put the cover on correctly. It would be better if the ends were stitched together and maybe if it was shorter. I love the humidifier itself, but this filter is terrible.
