The 5 star review is fake

Fox Valley Air is a marketing branch for Pure Opportunity from FilterQueen. FilterQueen is currently the only consumer level air quality control system recognized by the FDA as a Class II medical device. Made by Health-Mor Industries out of Cleveland, Ohio; FilterQueen has been a reputable product line for over 80 years. Yes, Fox Valley Air performs demonstrations of these products in home and operates on a referral platform, but does not "prey" on anyone. The overall mindset of team at Fox Valley Air is that the product can speak for itself without any gimmicks or fancy sales jargon. Like any sales organization there may be individuals who press harder than others for the sale. If you don't like buying/selling high quality items at an appropriate price point don't do business with them. Otherwise this company is filled with amazing people all over the world.
