What is the difference in the ionizer models?
Our best-selling models are the IG-133A and IG-133DG negative ion generators. The IG-133A has a metallic surface on top that attracts fine dust, pollen, mold, etc. and improves the performance and ion output of the unit slightly. It is less susceptible to decreases in negative ion output when the room humidity is low, such as in the winter, in an air-conditioned room, or in a desert environment. The IG-133DG has a built-in DustGrabberTM circuit connected to two dust collector surfaces that attract far more dust and pollution than the IG-133A. To determine which negative ionizer that you need: • If you live in a dry environment (dry in any part of the year), we suggest that you order the IG-133A or IG-133DG negative ionizer. • If you have high air pollution, such as a smoker in the house, the IG-133DG is a better choice. • If you live in a humid environment year-round, you can order the original IG-133 negative ion generator and save $10.00.
