Watts Premier RO-Pure 531411 4-Stage Reverse Osmosis System
Why Filter Your Water?

The RO-Pure water filtration system provides you with water that exceeds the quality of most bottled water, at a fraction of the price and eliminates the inconvenience of heavy bottles and containers. This process puts the bottling plant right at your kitchen. Our filters turn your tap water into an efficient source of great tasting, clean water. Many things can affect the quality and purity of well and municipal water such as water usage, temperature, and even weather. Household plumbing can also introduce contaminants such as rust and lead into your tap water. The RO-Pure water filtration system can alleviate these effects by providing a consistent level of filtration, giving you high quality water at a reasonable price.

Four-Step Water Purification Reduces the Tiniest Contaminants
  • 5-micron Sediment Pre-Filter traps particulate matter like dirt, rust and silt that will affect the taste and appearance of your water.
  • 5-micron Carbon Block Pre-Filter reduces chloramines, chlorine as well as unpleasant taste and odors.
  • RO Membrane removes up to 96 percent of dissolved solids and up to 99.9 percent of cysts, bacteria, and viruses. This step is the heart of the reverse osmosis technology. This 50-gallon per day semi permeable membrane will effectively reduce total dissolved solids (TDS), sodium and a wide range of contaminants such as lead, arsenic, perchlorate, chromium, copper and radium. It will also remove over 99.95 percent of cysts such as Giardia and Cryptosporidium. The larger production membrane of this state of the art system has been designed to reduce nitrates and nitrites from your drinking water.
  • Carbon Post-Filter for final "polishing" of drinking water.

Each individually contained filter snaps into place, including the RO membrane.

Product description

Product description

This four stage reverse osmosis system consists of a stage 1 five micron Sediment filter that traps particulate matter like dirt, rust, and silt that will affect the taste and appearance of your water. Stage 2 is a five micron Carbon Block filter that helps ensure a greater reduction of chlorine and other materials that cause bad taste and odors (these are called PRE-filters because they filter in front of the reverse osmosis membrane). Stage 3 is the heart of the reverse osmosis system, the RO Membrane. This 50 gallon per day semi permeable membrane will effectively reduce TDS (total dissolved solids), Sodium and a wide range of contaminants such as Lead, Arsenic, Percolate, Chromium, Copper and Radium. It will also remove over 99.95% cysts such as Giardia and Cryptosporidium. The larger production membrane of this state of the art system also means this system has been designed to reduce Nitrates and Nitrites from your drinking water. It is important that this system is properly installed and maintained with a minimum incoming water pressure of 40 psi for it to operate as designed. Stage 4 is a high quality Carbon filter (this is called a POST-filter because it filters after the membrane). The filtered water passes through the membrane and enters the storage tank. When you're ready for a taste, it will leave the storage tank and pass through this fourth stage on its way up to the faucet. The end result? Crystal clear, high quality, and great tasting water!
