Ozone 500-i Ozonator + Negative Ion Generator for Air and Water
This is two devices, two machines in one neat package! In addition to the powerful ozone generator, it also has a negative ion generator which can be used to clean room air and build up healthy negative ions. You get two devices (ozone generator + negative ion generator) in one solid compact unit. The Ozone 500i comes with silicone tubing, which lasts longer than the cheaper polyurethane tubing other low cost ozone generators usually come with. One point is, the ozone generator and negative ion generator run separately, and you choose whether you want to run the ozone generator OR the negative ion generator. They do not run at the same time. No bells and whistles, just simple, rugged, longer lasting design for years of ozone and/or negative ions.
