The Model 4000 series air cleaners from Aprilaire feature a MERV 13 filter, and according to company spokespeople, the industry’s only patented Air Cleaner Control, which gives homeowners the visibility and control they seek to manage Indoor Air Quality.

Aprilaire’s consumer research has found homeowners want and are willing to pay for the benefits offered by a whole home air cleaner, along with the interaction provided by portable air cleaners. The cleaner can be active 24/7, on the half-hour, for three hour intervals, or for 24-hour periods.

When installed next to a thermostat or on the air-cleaning unit, the new control provides validation the air cleaner is working by indicating through a sequence of bars that rise when the blower on the heating and cooling system is activated. It also indicates when the filter needs to be replaced, based on blower run time.

Coleman has released three new humidifiers: a high-capacity fanpowered humidifier, and small and large bypass humidifiers. Coleman believes these products provide a more complete line to meet the needs of any home with a forced air system.

Coleman humidifiers provide humidity in the form of pure water vapor to prevent minerals from entering the air stream. Water is supplied to a distribution tray and flows evenly across a water panel. Heat from the heating system causes the water to evaporate. Properly humidified air (vapor) is then distributed throughout the entire home.

During operation, a constant flushing action occurs, which sends mineral leftover from evaporation to a drain at the bottom of each humidifier.
