The Centralux, a central vacuum system, is unmatched in convenience.The main power unit, installed in either a basement or garage, is linked to inlets in each room, covering up to 7,000 square feet total.Unlike portable vacuums that can recirculate dirt and debris in the air, the Centralux carries dust, mites, pollen, animal dander and other allergens out of the home to improve indoor air quality. Plus, installing a Centralux is considered a permanent improvement that actually adds to the value of your home.
