REO Pure 10 Reverse Osmosis Review

REO Pure has been a very popular reverse osmosis (RO) manufacturer for us for the last several years. Before I was hired by Water Value Co., I had purchased a REO Pure 10 system so my opinions in this review will be unbiased. I will be looking at this RO from a consumer's point of view.

The REO Pure reverse osmosis system I'm going to review is the one I have in my home. It is around 10 years old and is designed to produce 14 gallons per day on a CTA membrane. The CTA membrane was replaced last year. They are no longer manufactured by anyone in the industry as the material the membrane uses is no longer necessary. CTA membranes were designed to handle the effects of chlorinated water. Anyone getting their water from a municipality, community well or adding chlorine to their well, needed to use a CTA membrane. Now we simply remove the chlorine with a carbon filter.

This REO Pure reverse osmosis system has a sediment and carbon pre-filter, the 14 gallon-per-day membrane and a carbon post filter. It also had a TDS (Total Dissolved Solids) indicator that plugs into the output line to indicate filter or membrane replacement. The indicator was just that; a light that came on if the TDS reading became higher that a certain level. What level? I do not know. I no longer use it because I have access to a more precise TDS meter. This RO is also connected to the ice-maker in the freezer. It has been producing purified water this way for 10 years.

Cooking, drink mixes, ice-water, coffee and tea are all products of the water from this RO for a family of six. The retention tank has never run out of treated water during normal use, so the 14 gallons-per-day produced by this system seems to be sufficient for our needs. One of the best features of this system is the fact that it uses industry standard sized sediment and carbon filters. I can pick up replacement filters for it anywhere. Not like some manufacturers (who shall remain nameless) that purposely manufacture systems requiring replacement filters which can only be purchased through them. A new REO Pure comes with a GAC-10 (Granular Activated Carbon 10-inch) and a P5 (5-micron sediment), but you do not have to use a GAC-10. You can use any standard carbon filter cartridge and still remove chlorine.

I did not install this particular unit. It was there when I bought the place, but I have installed dozens of these things in local homes and businesses. Installation is a breeze. Simply connect the water source, connect the drain line and mount the faucet. The only potential for difficulty is mounting the faucet. Drilling a hole in a stainless steel sink is easy, but a ceramic style sink can turn into a mess if you've never done it before. One possible answer to that problem is mounting the faucet next to the sink in the counter-top so that the faucet can still swing over the basin of the sink.

As you can tell, installation and maintenance are refreshingly easy and inexpensive. The main function of this REO Pure RO is to provide purified water for the household, which it does very well. The peace of mind provided by a reverse osmosis system is hard to beat. I know that if for whatever reason, our city water supply becomes temporarily contaminated, the REO Pure 10 reverse osmosis system will keep us safe. I also know that my family is consuming water with zero TDS or bacteria and that's a good feeling.
