Those devices use a process call IONIZATION to clean the air. What this does is make high voltage that jumps out into the air and attaches to particles in the air. Those particles are now attracted to anything with an opposite charge. In some machines there is a plate that has the opposite charge and a fan that pulls the air into the machine. When particles that are charged come into the machine, they are drawn to that plate and stick. The plate gets dirty pretty fast and has to be cleaned. The problem comes when the ionizer begins to spark. This creates ozone and ozone is harmful to people and animals, rubber and many other things. I looked up the name of the machine that you listed and the closest I can find is a really old reference to a radio shack device. the Environizer™ (630-0612/630-0613)
This device was made just after regulation by the federal government that says 50 parts per billion is the limit so that device SHOULD be ok. However it has to be maintained and cared for. There is a great article here:http://www.allergyclean.com/problems-with-ozone-generators-and-ionizers-that-produce-ozone/
Just keep in mind the difference between ozone generators and air ionizers, they are not the same thing. If you need more info let me know.
