Trouble Shooting

Q: I hear the fan turning, but I don’t see any mist. Is my humidifier operating properly?

A:Dry air is pulled through the system and a fan disperses invisible, moisture balanced air. There is no “mist” emitted. When operating normally you will feel only cool air coming from the unit. Monitor the water level in your Tank/ Base. If you notice a decrease in the Water Tank over 24 hours then the unit is operating normally.

Q:My unit has been running for several hours. I hear the fan spinning, but I do not notice the water level in the tank decreasing.

A:First, check the filter to ensure it is wet. If the pad appears dry, remove it from the Base and gently rinse under cool water. Reposition wet filter in the Base. You may also want to note the current moisture level in your home. If the humidity level is over 60% the unit will not put out much moisture as your air is already saturated. Also verify the upper enclosure and water tank are properly seated.

Q: My filter has turned light brown and rust colored. Do I need a new filter?

A:Probably not. Since your filter has been made with Protec™ antimicrobial the change in color indicates only a mineral deposit. Soak filter in a sink full of cool water to help break up deposits. The discoloration may remain but will not affect the humidifier’s performance.

Q:My humidifier doesn’t appear to be as clean as when I first purchased and/or I’m smelling an unpleasant odor. What should I do?

A:You probably need to replace your Protec™ Antimicrobial Cartridge. This cartridge helps your humidifier stay cleaner, longer and helps freshen the mist. If you have been using your humidifier regularly for over 30 days replace the Protec™ cartridge and follow the cleaning instructions.
