Product description

Product Description

The RO Pure Reverse Osmosis System consists of four separate stages. Stage #1 - Five Micron Sediment Pre-Filter that traps particulate matter like dirt, rust, and silt that will affect the taste and appearance of your water. Stage #2 - Five Micron Carbon Block Pre-Filter that helps ensure a greater reduction of chlorine and other materials that cause bad taste and odors. (The first two stages are called Pre-Filters because they filter in front of the Reverse Osmosis Membrane). Stage #3 - The 50 GPD Membrane is the heart of the Reverse Osmosis System. This semi-permeable membrane will effectively reduce TDS (total dissolved solids), Sodium and a wide range of contaminants such as Lead, Percolate, Chromium, Copper and Radium. It will also remove over 99.95% cysts such as Giardia and Cryptosporidium. Stage #4 - Five Micron Carbon Post-Filter (105341) which is used as a final polishing filter. It is important that this system is properly installed and maintained with an incoming water pressure of 40 to 80 psi for it to operate as designed. 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 the fourth stage on its way up to the faucet. The end result? Crystal clear, high quality, and great tasting water! In the Box: RO Pure Reverse Osmosis module (pre-installed filters), Parts Bag, 3 Gallon Storage tank, Faucet, and installation instructions (manual).

From the Manufacturer

If quality and convenience are what you're in the market for, then this is the water filtration system for you. These filters change out at the push of a button. You don't need to turn off the water supply to the system and there's no waiting for the system to depressurize. Each individually contained filter just snaps into place, including the membrane. In order to maintain your system in its top performance it is recommended to change out both the Sediment and Carbon Pre-Filters every 6 months, the Carbon Post-Filter every year and the Membrane every 2 to 5 years depending on the quality of your incoming water supply. This will ensure you have crystal clear, high quality and great tasting water! This system is tested and certified by WQA to NSF/ANSI 372 Lead Free and Certified to NSF/ANSI 58 Certified Reverse Osmosis Units. Contact us on 1-800-752-5582.
