We had the guy come out to see the dust in our home to see if the EPS they say they would put in our duct work would fix dust. Showed the guy ring of dust on washing machine lid . He said their EPS would fix it. Two men came over 10 hours late , asked for a drop cord , came back down stairs and asked me repeatedly about deer hunting on our property. Package is free meat and said nothing about the system. In the 2nd week we called and called no answer. Went on site sent notice no response. Now the people are saying it only takes out germs now saying they never said it takes out dust. They showed before and after slides of dust in presentation. They even have a thing in contact that only gives you option to go to Richmond VA to sue them. These people never brought chemical in our house , these people never ever said anything about buying chemicals EVER!! My wife asked the deer hunters what did she need to do next . The so called installers said call the guy James McAllister in 12 months to check it. This guy so they are saying does not even work there any more. It is a RIPE OFF They want come and get whatever it is so they say they installed an will not give us our money back. My wife has had nasal surgery in past . I am retired fire fighter we were trying this thing to help breathing. Do not let this company into your home!!
