iWave-R treats the air in any brand of residential duct air conditioning systems up to 6 tons (2400 CFM) in size with no maintenance and no replacement parts. Designed for universal mounting, the iWave-R  is easy to install inside or outside of duct, or can be attached magnetically near the indoor fan in the air handler. Simply connect to power using its patented multi-voltage input capability. Mount the iWave-R after the return filter. The iWave-R can be mounted before the coil if the primary concern is treating the coil. If the primary concern is treating the occupied space, then the iWave-R should be installed on the supply side of the coil. In regions with high humidity, it is always recommend being installed on the supply side of the coil. iWave-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 patent-pending self-cleaning design includes a programmable cleaning cycle that can clean the emitter brushes every 1, 3, 5 or 10 days. The iWave-R is factory set to clean every third day which is adequate for a typical installation.
