Indoor Air Quality
Few things are more important when it comes to your family's health and comfort than the quality of your home's indoor air. But that same air may not be as clean and healthy as you think. Consider this: U.S. Environmental Protection Agency studies have shown that Indoor Air Quality can be up to 100 times more polluted than the air outside - even in smoggy, urban areas.

To help protect the health and comfort of your family as well as your home and its belongings, the only truly effective solution is a whole-house solution from Aprilaire. Whether pollen, dust mites, mold spores or air that is too dry or too humid is your problem, Aprilaire has a whole-house, indoor air quality solution that can help.

Aprilaire Whole-House Humidifiers were introduced in 1954 as the first evaporative, flow-through design humidifiers. Aprilaire humidifiers introduce the right and healthy amount of moisture into your air, never too much or too little. Aprilaire humidifiers can help symptoms with dry sinuses, itchy skin, static shocks, dry, cracked damaged wood floors and furniture and help ease allergy and asthma symptoms.

The Aprilaire Models 1700 and 1720 Whole-House Dehumidifiers offer total comfort from the sticky, sweaty, and potentially unhealthy conditions caused by excess moisture. The 1700 and 1720 models differ only in capacity - with the model 1700 having a moisture removal capacity of up to 90 pints vs. the 1720 with total removal capacity of up to 150 pints per day.

An Aprilaire Air Cleaner can help rid your home of dust, dust mites, pet dander, mold spores, pollen, bacteria and viruses and more. Aprilaire Air Cleaners are installed as part of your home's central heating and cooling system - completely out of your way and out-of sight. Named the #1 whole-house air cleaner by a leading ratings magazine 3 years in a row. Aprilaire Thermostats control not just your home's heating and cooling, but your overall comfort. All Aprilaire Thermostats operate electronically (digitally). Unlike mechanical thermostats, Aprilaire Thermostats are mercury-free and provide pinpoint accuracy and control of single-or multi-stage forced air, heat pump or hydronic systems.

Aprilaire Whole-Home Ventilation Systems exchange the air inside of your home with fresh outdoor air. Aprilaire ventilation systems deliver the proper exchanges of fresh air for your home, making it a more healthy, comfortable and energy-efficient place to live.

One room too hot while another is too cold? Not with Aprilaire Zoned Comfort Control. Aprilaire Zoned Comfort Control is a system of more than one thermostat, electronically connected to a control panel which operates a number of dampers in your forced air heating/cooling system. Conditioned air is then distributed to various part of your home as needed.
