NSF certified water filter parts and reverse osmosis water filter systems and purifiers , your one stop solution to most water contamination and water pollution problems. Pure water and safe water guaranteed!

Frankly, these are useless features added just to help sell products. Membrane flushing is an old technology that is only used for commercial RO membranes these days. Most of the residential RO membranes now are using new technologies that require no flushing. The most dangerous is the "auto flush" type, because it actually "reduces" the life of your small home membrane by flushing it constantly, even when there is no need for it. We know others claim that with their flushing, their membrane can last 2-4 years. Yet our advanced membrane, without hassles of flushing, lasts 5-8 years if you just change your pre-filters regularly.

The built-in TDS meter is also just another marketing gimmick. We think adding it actually misleads customers rather than helping them, because the TDS meter does not indicate it is time to change your filters. It lights up only when your TDS is high —after your membrane is damaged! If the meter is on the system, you will tend to wait for the red light before you change the pre-filters. But then it is too late. The membrane is dead already when you see the light. So this function actually helps kill the membrane rather than preserve it. We tell customers to just change filters every year and their membranes will be protected. And we can send you a free hand-held TDS meter so you can check on the water once every few months or so if you are worried. This way there is no dependence on the monitor to tell you when to change the filters. | TOP |

Facts On Reverse Osmosis Water Filters

Reverse osmosis, also known as hyperfiltration, is the finest filtration known. This process will allow the removal of particles as small as ions from a solution. Reverse osmosis is used to purify water and remove salts and other impurities in order to improve the color, taste or properties of the fluid. It can be used to purify fluids such as ethanol and glycol, which will pass through the reverse osmosis membrane, while rejecting other ions and contaminants from passing. The most common use for reverse osmosis is in purifying water. It is used to produce water that meets the most demanding specifications that are currently in place.

Reverse osmosis uses a membrane that is semi-permeable, allowing the fluid that is being purified to pass through it, while rejecting the contaminants that remain. Most reverse osmosis technology uses a process known as crossflow to allow the membrane to continually clean itself. As some of the fluid passes through the membrane the rest continues downstream, sweeping the rejected species away from the membrane. The process of reverse osmosis requires a driving force to push the fluid through the membrane, and the most common force is pressure from a pump. The higher the pressure, the larger the driving force. As the concentration of the fluid being rejected increases, the driving force required to continue concentrating the fluid increases.

Reverse osmosis is capable of rejecting bacteria, salts, sugars, proteins, particles, dyes, and other constituents that have a molecular weight of greater than 150-250 daltons. The separation of ions with reverse osmosis is aided by charged particles. This means that dissolved ions that carry a charge, such as salts, are more likely to be rejected by the membrane than those that are not charged, such as organics. The larger the charge and the larger the particle, the more likely it will be rejected.
