Aerisa Inc

Aerisa, now rebranded as Air+ and headquartered in Rye, New York, manufactures bipolar ionization-based air purification and odor control systems. Originally founded as IONz International and rebranded to Aerisa in 2008, the company later adopted the Air+ name. Their core technology uses cold plasma ionization to release charged oxygen ions (O2+ and O2-) into air spaces, proactively attacking odorous and corrosive compounds at the molecular level. For the wastewater sector, Air+ targets hydrogen sulfide, ammonia, mercaptans, and VOCs at headworks, solids buildings, pump stations, and lift stations. Key products include the DM-6000 and DM-18000 duct-mounted auto-cleaning needlepoint ionizers for systems up to 6,000 and 18,000 CFM respectively; the 500F tube-style ionizer for commercial and industrial systems up to 10,000 CFM; the Ion Bar for air handler mounting with auto-cleaning needlepoint ionizers; the Odor Beast, an ionization-based scrubber for continuous odor reduction and corrosion protection in high-H2S environments; and the Supply Scrubber, a custom double-wall outdoor air handler delivering ionized air into buildings or tank headspaces. The company also offers AirCalcs+, a free web-based ASHRAE 62.1 IAQ Procedure calculation tool. Their technology claims approximately one-sixth the energy usage of traditional air cleaning solutions with no chemical byproducts, though operator reviews have reported reliability concerns including frequent bulb failures.
