Did you know....The American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) recommends that indoor relative humidity (RH) should be controlled between 30% and 60% (See chart below). Keeping your RH in this range provides many health benefits and helps to protect your home and belongings. Proper levels of humidity will also keep you more comfortable.
Controlling the Humidity in Your Home
Most homes cannot achieve the 30% to 60% range without having a humidifier or dehumidifier installed. To determine if your house is too dry or too humid, simply purchase a device called a hygrometer. 
A hygrometer measures the amount of moisture in the air and gives you an RH% reading. This inexpensive device can be purchased online from the Aprilaire eStore, part number 9960 Weather Station. Simply place it anywhere in your home and you can instantly see the level of humidity in your home.
The next step is to call you local Aprilaire dealer. The dealer can install an Aprilaire whole-house product that can control the RH to the correct levels, protecting your health and house for years to come.
