Yup I have several of these sharp air filter/humidifiers and I find that they really improve the indoor air quality. It's very subtle, and for the most part you don't even notice a difference when they are running. But when I have accidentally left one turned off for a while I have definitely noticed when I woke up with a horrifically dry throat and nose, or come home to a very stale smelling house.
