 60-day money-back guarantee on all products sold.

Five-year limited warranty on materials and workmanship on the following products:

  • IG-133 room ionizer
  • IG-133A room ionizer
  • DustGrabber™ ionizer accessory
  • IG-133DG room ionizer
  • IG-1215 ionizer

We have never charged anyone a restocking fee. After inspection of the returned merchandise, we refund the full purchase price, less shipping and handling charges (if any) of any ionizer or emitter displayed on our web site *.

Returned product(s) and all accessories (ion detector and ion emitters) must be received by us within 60 days of invoice date (or the day we shipped it to you, if that happens to be later than the invoice date) in like-new, saleable condition with all original packaging, ion detector, and ion emitter(s), etc. Before returning anything to us, please contact us for instructions and a return authorization first.

The bottom line is, the return rate on our products is less than one-half of one percent. That is a fact, and it testifies to the satisfaction of our ionizer customers.

But we do not want you to keep anything that you don't want or need, so if you purchase something from us and want to return it, please contact us for instructions and a return authorization.

* 60-day money-back policy applies to any standard ionizer or emitter displayed or sold on this web site. In other words, if we custom design a special ionizer(s) for your special application or installation, returns may be subject to a restocking fee or only covered under our warranty for materials and workmanship (that is, it/they may not be returnable for a refund or credit).
