Reviews of the Best Reverse Osmosis Water Systems of 2017
Watts WP5-50 Premier
Watts WP5-50 Premier is the ultimate NSF certified R.O water filter. It features a powerful 5 stage R.O filtration system comprising of a 5-micron sediment and a coconut-shell carbon. The sediment filter captures large solids like slit, rust which affect the taste of water, as well as reduce the health benefits of it. A 5-micron carbon filter banishes the unpalatable chlorine taste and other materials that cause the water to develop bad taste and odour. The device has another carbon block filter that has microscopic pores which block the microscopic chloramines. In the fourth stage of the filtration method, the water travels through the membrane. The paper-thin, porous membrane blocks hazardous materials such as lead, arsenic, nitrate, TDS, parasitic cysts and bacteria from the water. The final stage begins when the water is the storage tank is forced through the faucet. A GAC filter improves the taste of the water.
APEC Premium 5 Stage Reverse Osmosis Water Filter
Like Watts WPF, Apex also has a manifold 5 stage, GDP essence R.O drinking water filter system that produces quality mineral water 24 x 7.The mechanism doesn’t differ much from the other similar models.

What is an R.O. filter exactly? What does it do?
Reverse Osmosis is a well tried and tested method for water purification, also known as desalination. Untreated water consists of harmful chemicals, contaminants and salt. The water is pumped using high pressure through a semi-permeable membrane which expels the impurities. Reverse osmosis systems are also used for removing hard mineral ions from water, this process is called water softening. Although there is a significant difference between water filters and water softeners, R.O filters, to a certain extent, performs both functions with equal efficiency. The most dilemmatic part about choosing a right filter is that all the devices look the same. To an uninitiated, it’s almost impossible to distinguish between them without the knowledge of membranes and filters which are the heart and soul of such equipment.
How does it work?
The scientific term for reverse osmosis is hyperfiltration. In this process, dissolved inorganic particles such as salt are decreased to the molecular level. Clean water is achieved by pushing the tap water through a semi-permeable membrane placed inside the filter. These thin membranes only allow water to penetrate through it, barring any other material. The strained pollutants are then flushed down through the drain. The conditioned water is delivered to a holding tank. You can obtain the water anytime by opening the faucet.
Apart from the quality of the membrane, another critical factor that impacts the quality of filtration is the type and intensity TDS in the water. It is an abbreviation of Total Dissolved Solids. The temperature and force of water are also essential. Remember, pollutants with a molecular weight above 200 are likely to be discarded by the system. Below I’ve elaborated the process of reverse osmosis water filtration step by step for a better understanding:
- Prefiltration: In this primary stage, the water enters the system and flows through a prefilter. This step is mainly important for eliminating large particles (scale, rust, slit) from the water, in order to prevent clogging of the membrane. Activated carbon prefilters, integrated into some advanced devices of today push out chlorine particles as well as other contaminants from the water.
- Membrane: During the second stage, the water traverses through the center of the system, the membrane. This special membrane contains numerous microscopic pores that allow only Hydrogen and Oxygen molecules to permeate. As you know, water is composed of 2 molecules of hydrogen and one molecule of oxygen, it can easily pass through the membrane. The tiniest particle which made its way through the prefilters is blocked by the membrane. The particles then exit through the drain.
- The last stage: Post the filtration process, the water gets stored in the holding tank. The automatic shut-off feature holds the water inside the system. It doesn’t come out until you turn on the faucet. The final stage of the R.O method is carbon filtration that comes into being when you open the faucet. The innovative carbon filters remove chlorinated taste and odour from the water. Once you taste the water from an R.O filter, you’ll know why it is so special. After the completion of the three consecutive phases, up to 99% percent of dissolved particles, bacteria, virus, chemicals and hard ions get removed from the water.
Note that all R.O systems can strain dangerous pesticides, chemicals and bacteria of having smaller molecular size than the water. Only R.O systems with carbon filters can perform the meticulous task of abandoning these difficult-to-remove materials from water. Standard R.O filters tend to waste approx. 2-3 gallons water during the purification process.
Wrapping up the Reverse Osmosis Confusion
Water is life-clichéd but true. Reverse Osmosis systems are one of the smartest ways to tick off harmful materials from water. Contaminated water can trigger a number of diseases. Balancing the level of salt and pH in the water is the basic function of an R.O filter. Since the market is inundated with various models, it’s not unlikely to get overwhelmed while trying to find the best reverse osmosis system. Be wise enough to get reviews from the trusted sources. The seller might give you an exaggerated description for personal gains. The products I’ve reviewed in this article are the best in the business and have received praises from other experts.
