Our IG-133- series negative ionizers generate FAR more usable negative ions than others costing several hundred dollars, yet sell for a fraction of the cost. They are genuine, high-density negative ion generators.

Most cheap "ionizers" being sold are actually ozone generators and produce few, if any, negative ions.

"I first purchased your products over a year ago. They are excellent and unique in the field. I believe that your products are superior in performance to any others I've found or used. I think you'll understand what I mean when I say that your approach is 'no-nonsense.' You produce products of the highest efficiency because you will not sacrifice performance for appearance. Your products are certainly not the most `flashy` looking on the market, but as your site reports (and I, myself, have had an opportunity to test) many of the most flashy products don't really `produce` negative ions. So, thank you for both the your products and your integrity."

"I wanted to thank you for the promptness of your order and wanted to wait to write you until I had used the ion machine for about a month to get a good feel for if it made any difference in the way I feel. I can definitely say that I wake up with more energy and in general, just plain feel better!!! In fact, so much better that I would really like to have one of these machines with me all the time..."
