When I was looking to buy a negative ion machine there was very little independent information available on the web, and what was out there was highly technical in nature. It took sifting through a lot of websites and pdf's to get the necessary data and make an intelligent choice on which brand/model to buy for my own place.
I have spent countless hours pouring over the information available and decided to turn it into a website to help you make your own search easier. On the resources page I have added a list of all the resources I used in putting this site together. You are free to use them for further research if needed.
One thing you should take away from this website it takes a little bit of digging to find a suitable negative ion generator. You want to stay away from those that generate ozone.
