Dry air difficulties
Relative humidity is the percentage of moisture in the air compared to its maximum capability to hold moisture under the same conditions. 70 degree air can hold more than 12 times as much moisture as 10 degree air. Outside air at 10 degrees and 70% relative humidity drops to 7% relative humidity when heated to normal room temperature without other internal sources of moisture, such as cooking, laundry, showers, etc.
Consider this: the relative humidity of the Sahara Desert is 25%; Death Valley is 23%. The average heated home has a relative humidity level of 13% to 16%.
That's only a fraction of the humidity recommended for the average heated home, and it's this 'desert dryness' that makes you feel uncomfortable and takes moisture from your home, furnishings - even you and your family.
The recommended indoor relative humidity is 35% and up to 45% in warmer climates or where special construction prevails. Not all humidifiers have the capacity to reach these levels.
Doctors often times have mentioned dry air as one of the causes for nose, throat, and other physical aggravations.
Heated air dries out and shrinks wood framing around doors and window frames. Gaps will then occur, permitting cold outside air infiltration. Heat loss and higher heating costs are often the result.
Heated, parched air causes separation of wood in floors, trim, and furniture...excessive wear of fabrics and carpets...loss of piano tone quality... wall and ceiling cracks...plant damage and annoying static shocks. These are all by-products of dry air.
Aprilaire is the answer
Proper humidity reduces heating costs by stopping wood shrinkage, which reduces cold air infiltration around door and window frames. In turn, you'1l feel warmer at lower temperatures. You can actually dial down your thermostat and still be comfortable.
In cases where excessive dry air has been the cause of physical aggravations, doctors have prescribed whole-house humidification.
Furnishings are protected with proper humidity too - reducing the damaging effects of heated, parched air upon everything from your wood floors to your plants.
Aprilaire, safe and proven
Aprilaire® humidifiers are safe and proven. They were the first evaporative, flow-through design humidifiers, and, since their introduction in 1954, millions of users have enjoyed the many benefits of proper humidification with a minimum of maintenance.
Featuring the Auto-Trac™ Control System, many Aprilaire humidifiers are now even more convenient, automatically adjusting to outdoor temperature to ensure optimum humidification inside. This newest generation of humidifiers provides matchless convenience in humidification control.
All Aprilaire humidifiers produce humidity in a safe, pure water vapor form. No mist or droplets are present which can carry impurities. The flow- through design is your assurance that all minerals and impurities left from the evaporation process are either flushed down the drain or deposited on the replaceable Water Panel® evaporator.
A natural process
All Aprilaire humidifiers utilize Nature's own process - the introduction of humidity in the form of water vapor. Aprilaire provides the refinements necessary for positive, accurate humidification control.
