The new Luxaire® Acclimate™ Model 4000 WaterSaver Humidifier from Johnson Controls, the global leader in building efficiency, features a patented water delivery system that includes:

•    Wicking water panel that uses a sponge-like action to move water from the bottom of the panel toward the top, ensuring all  water in the unit is used during the evaporation process
•    Electronic water level sensors
•    Small float chamber that eliminates the need for a reservoir

The technology and design of the Model 4000, including quick left-right bypass conversion and reversible housing, allow for easy installation and require minimal maintenance. All humidifier housing parts that come into contact with water are nonmetal (except the valve and humidifier pad) and will not rust or corrode under normal operating conditions. In addition, the humidifier pad and scale control insert efficiently trap mineral deposits.

The WaterSaver’s performance benefits make it suitable for a variety of applications, including homes with septic systems, older drum-style humidifiers and no floor drains. The whole-house humidifier conserves water and energy and improves indoor air quality and comfort.

How It Works

An Aprilaire Whole-House Humidifier is installed directly to your central new or existing heating and cooling system. Humidity is introduced into your home’s air in the form of water vapor, which prevents minerals from entering the air in your home and potentially into your lungs. Water is supplied to the distribution tray, allowing it to flow evenly across the Aprilaire Water Panel®. The resulting humidified air is then distributed via your heating and cooling system ductwork throughout your home.

Protect your family and your home from the unhealthy and damaging effects of over-dry air. Dry nose, cracked, itchy skin, and sore throats. Aggravated allergy and asthma symptoms. Painful static shocks. Chipping paint and plaster. Splitting or cracked wood floors, furniture, trim and molding. Sound familiar? Why go through another season with these problems when there is a solution—an Aprilaire Whole-Home Humidifier.

Turning your temperature up in the wintertime will keep you warm but won’t increase your home’s humidity level. Daily activities such as showering, cooking and doing laundry don’t produce enough moisture to keep your home’s air from being too dry. According to medical experts, many viruses thrive in low humidity increasing the likelihood of catching colds, flu and upper respiratory ailments. The American Society of Otolaryngology even reports that it is important to prevent an overly dry environment because it makes people more susceptible to infection.

A Whole-Home Humidifier from Aprilaire, installed by your heating and cooling professional, will deliver the perfect amount of moisture to your air making you feel more comfortable at lower thermostat settings. In fact, the EPA states that you can save up to 4% on your heating bill for every degree you lower your thermostat! Increase your family’s level of comfort and protect your valuable furnishings by adding just the right amount of moisture with an Aprilaire Whole-House Humidifier.

“If too dry an environment is your problem, consider a humidifier. Clues like awakening with a sore throat, dryness in your nose, or even a nose bleed are signs of too little humidity.”
