The system is good and should improve health. However, beware, here in Florida, a company is selling it for about twice the listed retail price which is, approximately 675 plus installation 250. EQA (Environmental Quality Assurance) states that the system usually costs, not installed, 2,495 and from there they suggest a discount if you take it on the spot. Finally the invoice raises to 1,635 an excess of 700! The salesman came home stating that he was a technician and not a salesman and that he would check with the company ... etc. etc.
The guy who installed it (1 hour) referred to him as the "salesman"!
They got me but I intend to fight back!
