D and S Air believes in "whole home" HVAC care. As the leader in innovative solutions to indoor air quality problems, it’s no surprise that we recommend and install the PuriFi system.

When particulate levels are too high the PuriFi PM Sensor activates the patented PuriFi Generator. The Generator, which is installed in your central HVAC system, uses their patented Airborne Molecular Purification (AMP) technology to begin sending an overabundance of natural, high-energy, molecular ions through all of your air ducts.

The patented blend of natural, long-life, positive, and negative ions flood every room and begin the purification process. Each register in your home or business becomes an air and surface purification system.
