Running your heating system in the winter pulls moisture out of the air, causing the air inside your home to become very dry. Humidifiers reduce dry, uncomfortable air, so you can breathe easier. Enjoy a more comfortable interior with one of these quality humidifiers.

  • The Preferred™ Series Steam Humidifier provides stable humidity levels throughout your home with a daily moisture output of 34 gallons, ideal for larger homes.
  • The Preferred™ Series Large Fan-Powered Humidifier provides increased comfort with 18 gallons of daily moisture delivered quietly and evenly throughout your home.
  • The compact Preferred™ Series Small Fan-Powered Humidifier maintains optimal humidity levels in modest-sized homes with 12 gallons of daily moisture output.
  • The Preferred™ Series Bypass Humidifier provides 12-gallon or 17-gallon daily moisture outputs when added to a furnace or other warm air delivery system.


Summertime temperatures in southwest Michigan tend to be moderate, but residents do experience slightly muggy months when relative humidity spikes. Increased humidity inside your home can lead to mold and mildew growth and provide a humid environment for dust mites and other allergens to thrive. Improve your home’s indoor air quality and protect asthma and allergy sufferers in your household by controlling moisture and reducing indoor humidity with a whole-house dehumidifier. Whole-home systems offer a more comprehensive solution than portable units that only alleviate humidity in a single room.

  • The Preferred™ Series Whole-home Dehumidifier is energy efficient and removes moisture through an independent refrigeration system that includes a blower, coil and compressor and uses a permanent MERV 8 filter that captures dust particles.

These systems are compatible with any furnace or fan coil and can even be mounted remotely with top or side ducting when you have limited space. Whole-house dehumidifiers operate quietly and require minimal maintenance that typically includes coil inspection and cleaning or replacing the filter.

Air Purifiers

Improving your indoor air is easier when you treat the air flowing into your heating and cooling system before it circulates. Whole-home air purifiers remove pollen, mold, bacteria and viruses from the air before they can enter your home.

  • The Evolution® Air Purifier is the highest performing solution for furnaces and fan coils and features Captures & Kills™ technology designed to remove harmful airborne particles that aggravate asthma and allergy symptoms and could carry cold and flu viruses.
  • The Preferred™ Series EZ Flex Cabinet Air Filter features an efficient MERV 10 filter that treats 100 percent of the air flowing through your heating and cooling system.


Bring fresh, prefiltered air indoors without opening a window with a ventilator. These indoor air quality systems replace the stale, polluted air trapped inside your home so you can enjoy cleaner air.

  • The Preferred™ Energy Recovery Ventilator is ideal for year-round use in larger homes in hot climates and brings fresh air in while keeping unwanted airborne moisture out.
  • The Preferred™ Upflow Heat Recovery Ventilator is ideal in areas with colder winters and low to moderate summer humidity. Available in a variety of sizes, these systems feature a crossflow core that melds indoor heat with incoming air to provide fresh air throughout your home.
  • The uniquely designed Legacy™ Series Energy Recovery Ventilator can mount directly onto furnaces or return air ducts to provide lasting fresh air solutions for any budget.
