The Duo-11/24V and Duo-14/24V air purifiers are two new additions to Field Controls’ Healthy Home Combo System line of products. The purifiers include a two-stage purification process that works with virtually any forced-air system, the company says. The first stage of the purifiers uses an ultraviolet germicidal light that neutralizes intruding airborne bacteria, mold, fungi and viruses. The second stage incorporates technology to convert harmful organic compounds and odors into harmless water vapor. The system can be installed over the A-coil, in a return or in the supply duct of any HVAC system, and is available with an 11-inch or 14-inch ultraviolet C lamp.
