Product review (4 stars): Filter is fine
The only complaint i have about this Holmes humidifier is it doesn't tell you if the filter needs to be replaced. This is at my parents' house, so every time i visit, i check the filter, and it's always so old and dried out that it doesn't even draw water any more, making the humidifier spectacularly ineffective. And when it's that old and crusty, it's kind of disgusting to take the old one out, and the base needs a thorough cleaning. More disgusting. But cleaned up, new filter installed, i stop having nosebleeds at their house when the humidity is consistently well below 20% outside, so i love it!
