I like the RO OmniFilter

I've had mine for about 4 years and the water quality has been great. Unfortunately, the plumber 'rented' it to me for @22/month that was supposed to service the unit and change the filters once a year. The last two years, they did not use the correct filters and I stopped paying them when they refused to properly replace the filters. I'd advise you to order from this site and have your trusted plumber install it. Get the filters while you are at it. The unit is great!
