1) Every component of our Ultra RO system is U.S. made and FDA/ NSF approved. Many other systems in the water industry now use lower quality parts (foreign cloned) that break easily, clog up the system in a few months, and have a much shorter life-span.

Original Extruded KX Carbon Block Filters in every Ultra R.O. System ! 2) Our pre-filters are patented KX extruded solid carbon blocks. "Extruded block" means uniformly solid construction which prevents channeling or bypassing. Their superior material and construction offer greater absorptive and dirt holding capacity than other non-extruded carbon blocks or G.A.C. (granular activated carbon) filters. Most importantly, our carbon blocks do not release any carbon fines to clog up systems.

The Ultra RO System is equipped with two extruded carbon blocks to last longer before change-outs. Our pre-filters can treat up to 4000-5000 gallons of "filtered water", While other RO systems in the market typically can only last about 2000 gallons of filtered water. This means their filters have to be changed twice as often as ours. When other vendors claim that they can treat up to 10,000 gallons of "water," it means they can deliver only 2000 gallons of "filtered water." Remember, all RO systems need to generate brine water in order to produce clean, filtered water! You have to divide their claimed total numbers by 5. Once you understand this, you will not be misled by any number games.

3) Our FILMTEC membrane's average rejection ratio is proved to be about 98% to 99% and it lasts 5-7 years easily. While most other system's membrane rejection is between 89% and 95% and you would need to replace their membranes in only 1-2 years.

4) Our Ultra 5-stage RO is specially designed to treat all types of water while other ROs can treat only certain types of water. Our system has high allowances for variations in pH (2-11), in maximum dissolved solids (up to 2000 ppm), in water pressure (0 to 100 psi), in output (45-250 gpd), etc.... Meanwhile, a standard RO in the market is limited and can only treat water in the pH range 4-8, with maximum solids up to only 1000 ppm, with water pressure from 60-80 psi, and with output of only 15 to 25 gallons per day. This means if your input water happens to be harder, more acidic, or heavier than the usual standard water sources, those lesser RO systems will break down gradually, and not knowingly, you would be drinking bad water —your investment is wasted. |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.
