A hydrometer is an inexpensive device that can measure indoor humidity levels. They can be purchased at any hardware store or through FamilyCare directly. A. Humidifier performance is rated in output per 24 hours. This simply means how much moisture is put into your air in a 24-hour period. The more the humidifier puts out, the better it is and the larger area it will humidify.
Capacity is simply the amount of water that the humidifier or vaporizer holds.
It is normal not to see any mist in Cool Mist, or evaporative type humidifiers. This is because the mist naturally evaporates off the filter. You will know the humidifier is working however because the water disappears. With Warm Mist and Ultrasonic models you can actually see the mist. Since everyone has different needs, FamilyCare offers both cool and warm moisture humidifiers to meet a variety of preferences.
