Want to know the secret to boosting your profits through effective humidity control? Only an Ultra-Aire system can provide the high level of humidity control that a home needs, regardless of air conditioner operation or outside moisture. Small, inexpensive residential dehumidifiers just aren’t powerful enough or efficient enough to properly dehumidify a whole home. Two fifty-pint residential dehumidifiers use more power than a single Ultra-Aire, yet they remove considerably less water from the air. A single Ultra-Aire will maintain relative humidity levels below 50% in air-conditioned homes up to 2,500 square feet. In larger homes, a top-of-the-line Ultra-Aire can control up to 3,500 square feet, or multiple units can be easily employed.
