TRANE CleanEffects™ air filtration system and Perfect Fit™ electronic air cleaners use only about the same amount of electricity as a 40-watt light bulb. However, to do their job, the heating and cooling system must be running.

In this regard, Trane Home Comfort Institute experts report that new technology in the field of electronic fan motors and controls is drastically reducing the cost of running a fan continuously. Setting your thermostat to run the fan continuously helps filter your air and gives you even temperatures from room to room. Consult with your Trane dealer if you live in a particularly humid area before running your fan on continuous.

And they say this new generation of motors and controls not only allows more economical air cleaner operation but also lowers overall operating costs, reduces noise and provides greater levels of comfort.
