Air Cleaners

American Standard AccuClean Air Cleaner

American Standard has been finding new ways to deliver whole-home comfort to your family for over 100 years. When it comes to providing that comfort, temperature is only one piece of the puzzle. The fact is, indoor air quality plays a key role. Today’s homes are better insulated, tightly sealed and use less energy. Unfortunately, this also seals in humidity, dust and other indoor pollutants. In many cases, the quality of air inside a home can be worse than it is outdoors.The American Standard AccuClean is the most effective whole-home air filtration system on the market. Since it removes up to 99.98% of allergens from the filtered air and catches particles down to .1 micron in size, AccuClean is 100 more times more effective than a standard one-inch throwaway filter.


Aprilaire Humidifiers

Aprilaire Whole-House Humidifiers were introduced in 1954 as the first evaporative, flow-through design humidifiers. Since then, Aprilaire Humidifiers have been imitated, but never duplicated. They continue to lead the way in whole-house humidification systems. And only Aprilaire offers fully Automatic Digital Humidifier Control to monitor outdoor temperature and indoor humidity levels while providing convenient troubleshooting and maintenance reminders.
