Evaporative humidifier having wick filter with color change indicator

A evaporative humidifier comprising:

• a. a base including a portion defining a reservoir for holding water,
• b. a housing mounted on said base over said reservoir said housing having an air inlet and an air outlet,
• c. a cylindrically shaped wick filter seated in said reservoir and extending into said housing, said cylindrically shaped wick filter having an open end and a sidewall, and
• d. a fan inside said housing for drawing air into said housing through said air inlet then into said cylindrically shaped wick filter through said open end, then out through said sidewall of said cylindrically shaped wick filter and then out of said housing through said air outlet,
• wherein said wick filter further includes a color change indicator disposed on said wick filter for providing indication when said wick filter should be replaced.
