With technology installed in hundreds of thousands of applications, Nushield-R is a self-cleaning, no maintenance needlepoint bipolar ionization generator designed specifically for treating air in any ducted HVAC system up to 6 tons. As the air flows past the NuShield-R, positive and negative ions actively treat the supply air, reducing certain bacteria and viruses* in the coil and living space. The ionization process also reduces smoke, odors (cooking, pet, VOCs), as well as other particles (no more sunbeams) in the air. Nushield-R meets UL 2998 zero ozone emission certification.
NuShield-R treats the air in any brand of ducted HVAC system up to 6 tons (2400 CFM) in size with no maintenance and no replacement parts. Designed for universal mounting, the NuShield-R can easily be installed inside of the system using the included hardware or it can be attached using the integrated magnets. Simply connect to power using its patented multi-voltage input capability. Install downstream of the last filter in the HVAC system. Alternate mounting locations are on the supply air duct or the return air duct after the filter. NuShield-R always works at peak performance, producing over 160 million ions/cc per polarity (320 million total ions/cc), more than any other ionizer product on the market. Its patented self-cleaning design includes a programmable cleaning cycle that can clean the emitter brushes every 24 hours. NuShield-R does not create “black walls” as negative-only ionizer products will do.
