Holmes offer many different styles of warm mist and cool mist humidifiers for your office or house, no matter how large or small the room.
All models have special treatments to inhibit the growth of mold and bacteria. Many also have digital programmable humidistats to help maintain an optimum humidity in your room. Some even have a filter condition monitor.
There is a wide range of filters available, and it is recommended that filters are replaced regularly, as efficiency decreases when filters get older.
