I just want to let you know how happy I am with my system. I have a condo in Mesquite Nv. and the water is so bad there that I couldn't take a shower with out flaking skin after the shower and the water smelled so bad. I had the system installed in Dec.2007 and I changed the filter in Feb.2008 the filter was dirty but the water tasted great and no smell. I love my PSE1800 full house system.It is so easy to maintain I just have to change the filter and that only takes 10 minutes to do.My husband and I have High Blood Pressure and Diabetes and this was the only system that I could find that didn't require salt. No more buying bottled water .What a plus that is.I would recommend Water Filter-USA Systems to anyone that wants to improve there quality of water coming into their homes or businesses. The Customer Service is the BEST EVER. I had to email the Customer Service to ask for help in finding someone that could install my system 80 miles out of Las Vegas and I received an email back with a Name and phone number within 24 hours. I called to get a new O-Ring and I had it within 3 days. I just called to get 2 extras O-Rings to have on hand I spoke to Richard and he found out about the one I would need and called me back within a few minutes to say they were sending them to me right away. GREAT CUSTOMER SERVICE RICHARD AND WATER FILTER-USA.Thank You
