Water is life and one cannot imagine a life without it. This is the reason we all give utmost priority to ensure we get 
clean water to drink. But with increasing pollution, the quality of water is not the same in all the locations, particularly in metropolitan cities where the water is full of contaminants that create huge adverse impact on our health. If the contaminated water is purified and consumed with pollutants, it can cause such deadly diseases that one can’t even imagine. Therefore, if the quality of water is low, it must be purified properly with the help of proper filtering mechanisms, and water purification systems are one of the best known options. Today, there are various types of water filters that are available in the market but one of the best in the lot is the reverse osmosis water system. Reverse Osmosis Filtration is an effective water purifying system that can kill and remove up to 99% of contaminants present in the water. It also removes various types of chemicals present in the water that couldn’t be normally filtered by other water filters. And this is the main reason, these reverse osmosis water systems are more popular than any other system available in the market today. With so many features and types, there are many types of reverse osmosis systems available and hence it is difficult to pick the right one. Let us look at some of the best ones in the lot and understand what is it that makes them the top players in their domain. We have also written a complete guide about the best water purifiers.
Key features to consider when choosing the best reverse osmosis water system
If you have ever taste the water that is purified by a reverse osmosis water system, you would know how refreshing
and pure it tastes and smells. Reverse Osmosis (RO) filtration is perhaps one of the best and most popular water filtration methods available and provides outstanding quality of water for your family and friends. Here are some of the features you can consider while buying a RO:
The Design
Reverse Osmosis filtration technology has evolved a lot in the recent years to give you safe and refreshing drinking water. If the filtration system is well designed and properly operated, it offers troublesome performance for long periods of time. Especially the membrane used in these filtration systems are designed for long useful life, hence while picking the one for your house, you must take into consideration this feature. On the other hand, if there are design flaws in the system, the operation of reverse purification system can lead to problems and reduces the membrane life, which is one of the most important part of these systems. Check out our complete guide about the best whole house water filters.
Material
Reverse Osmosis Water filtration systems use semi-permeable membrane to filter out molecules, ions and larger particles from the impure water, making it fit for drinking purposes. In the system, an applied pressure is utilized to overcome the osmotic pressure that is driven by chemical differences of the solvent. The result is that solute remains intact on the pressurized side of the membrane and pure solvent passes on to the other side. That’s why it is important that the membrane should be such that it doesn’t allow the ions and molecules to pass through it but at the same time, it should let the smaller particles (that’s the solvent molecules) to pass through it.
Filtration Stages
Reverse Osmosis system includes various stages through which the contaminated water is cleaned stage by stage,
giving you highly purified water as a result. Most of the contaminants that lead to diseases are filtered out in a stage that makes water pass through the semi-permeable membrane, however, there are additional stages that make sure other different types of contaminants are also filtered out. While some of the ROs have 3-stage structure, there are models that come with 5 stages and 7 stages also. As the name suggests, the difference lies in the number of stages these systems use to filter out the pollutants. For instance, the 3-stage RO comprises of a pre-filter stage, the reverse osmosis membrane stage and the post filter stage. Similarly, the 5 stage reverse osmosis drinking water system comes with – Polypropylene sediment filter stage, carbon water filter, 1 Micron Polypropylene water filter, osmotic membrane stage and carbon water post filter stage.
The most basic systems are designed with only two stages – the first stage, known as the pre-filtration stage, that uses a carbon block to filter out certain contaminants and the second stage that filters out the tiny particles that passed out from the first stage.
But normally the tap water doesn’t have high pressure and hence the rate of flow of water into the system is slow. If the water remains in the storage tank for long, it develops a taste and to solve this problem, more stages are introduced to get high quality drinking water.
The third stage is the post filtration stage that comes with second carbon filter to remove the unwanted taste of water. The fourth is usually an augmentation of third stage, where a sediment is placed before the carbon filter to filter out debris and dirt. The first stage is not an actual filtration stage but it reintroduces some of the minerals that the membrane had filtered out in the filtration stages. The sixth, seventh and eighth are just the advanced improvement stages that aim to remove whatever contaminants had escaped in the initial filtration stages of the purification system.
Pros and cons of Reverse Osmosis Water System
Pros:

Cons:
- Some of the basic RO systems remove necessary minerals from the water as part of purification process
- Some of the models do not have proper pressure pumps that can retrieve only 10-15% of the water and rest is drained out along with impurities

of impurities are in them. This allows you to choose a filter best suited to your needs. For example, cities like LA, Dallas and Washington in the USA use chloramine – an aggressive disinfectant – to treat it’s municipal water supply. Therefore, a user should look for a filter that is effective at reducing chloramine, such as those with catalytic carbon. If you have ‘hard’ water that is high in mineral content, avoid using fine filters as it will cause them to clog faster.
medium, which is a mix of 55% copper and 45% zinc mineral alloy – effective for reducing chlorine and water-soluble heavy metals. Also in the top is a crushed mineral filter stone to enhance the water’s PH and control scale on internal plumbing. Both are effective at prohibiting the growth of bacteria and algae.
water filtration system is particularly effective at reducing iron and manganese, up to 99%, thanks to an iron and manganese filter that lasts up to three times longer than greensand, as the catalytic media is not consumed in the process. In a test of water with an iron level of 6, the filter was able to reduce it to less than 0.01 parts per million (ppm., and manganese from 3 to 0.01 ppm.

expensive filtration systems. However, if the water in your municipality is just lightly contaminated and lacks heavy metals, a two-stage design may suffice.
Built for high performance, the system provides healthy, great tasting water for the entire home, with no drainage, back flushing or water waste. It is capable of removing up to 97% of chlorine, thus giving users healthier skin and hair by reducing the body’s exposure to harsh and synthetic chemicals that may cause damage and excessive drying. This also means better quality air, as chlorine can evaporate in the shower steam. Meanwhile, cleaner water ensures that clothing is preserved, and requires less detergent.
does the a decent job, especially with well water applications. Not only does it provide clearer and better tasting drinking water at a fraction of the price of expensive models, it also captures sediment, dirt and rust for cleaner water for bathing and washing. Consisting of a carbon filter media made from polyester material, it reduces chlorine and impurities as small as five microns in size, in addition to eliminating sulphur which gives water that rotten egg smell and taste. However, the single filter has limitations as it is unable to filter certain elements such as flouride.
inexpensive solution to your household’s water woes. A three-stage system, it helps to remove dust, dirt, silt, sand, rust and scale particles at the first stage through a premium quick-connect 5 micron sediment filter.

Boasting not one or two but a 5-stage design, it is capable of reducing over 1,000 types of contaminants, including lead, chlorine, arsenic, fluoride, asbestos, calcium and sodium, in addition to preventing bacteria and viruses. Suitable for both municipal and well water, it consists of a multi-layered filter system with three pre-filters. The first stage is a polypropylene sediment filter, then a granular activated charcoal which helps to reduce the ‘hardness’, and last but not least, a carbon block CTO filter. The mainstay of the system is its Reverse Osmosis filter, made to remove contaminants down to 0.0001 microns.
m bad tastes and odours.
immunity and prevent diseases, increase metabolism, aid in weight loss and slow down the aging process by removing free radicals. Some pitcher filters not only filter but also ionises water, upping its alkalinity, whilst adding beneficial trace minerals such as calcium and magnesium – which tend to be filtered out in reverse osmosis or whole house filtration systems.
turns ordinary tap water into great-tasting, potable drinking water, without the need for expensive reverse osmosis systems. Touted to remove 2000% more contaminants than its competitor brands, the Aquagear filters out harmful substances such as fluoride, lead, chromium 6, chloramines, mercury and chlorine – whilst maintaining healthy trace minerals like calcium and magnesium.
water, whilst making it safe to drink. The set comes with two multi-stage PH001 filters, consisting of a zeolite, stone and ceramic ball blend, micro nets, activated coconut carbon charcoal and ion exchange resin. They work to remove up to 99% of chlorine, chloramine, VOCs, sediment, sand, rust and turbidites, whilst also filtering heavy metals such as arsenic and lead, for odourless, colourless drinking water. Fluoride is reduced by about 20%. Meanwhile, remineralisation adds healthy minerals such as selenium and calcium, so if you have hard water, expect some cloudiness, especially if you leave the water in the filter for several days. Overall, the filter impressed with its taste and quality, which had a smooth and silky texture.
blends carbon and ion exchange materials to reduce 96% of mercury and 95% of selected industrial pollutants, as well as chlorine for better tasting, odour-free water. Its carbon filters are made from coconut shells that have been heat treated with steam, which produces pores within each grain of carbon with up to 1,000 square meters of surface area per gram of carbon – ideal for absorbing and trapping contaminants. Per NSF certification, the filter is able to reduce 21 types of contaminants. This may not seem as much as some other filters on this list, but for regular use, the PUR suffices.
tastes and odours from chlorine, copper, zinc, mercury and cadmium, typically found in municipally treated tap water. This is achieved through an activated carbon shell. Users should note that while the Brita is sufficient as a basic filter jug, it will not be able to remove certain heavy metals or contaminants such as lead, asbestos, VOCs like benzene, or microorganisms such as protozoan cysts. Given its price and performance at reducing the taste and smell of chlorine, it is still a noteworthy option to consider.
cadmium, five of the most common contaminants in municipally treated tap water. If you have metallic tasting water, most likely from zinc, the filter is able to significantly reduce this, in addition to the odour of chlorine. Built in mesh screens prevent unsightly black flecks. The final result still maintains a healthy level of fluoride, which is beneficial in small amounts to promote strong teeth. Apart from the five contaminants mentioned above, the filter should not be used as a water purifier, as it is unable to filter out microbial organisms such as protozoa, bacteria or viruses.
seven-stage cartridge made from ion exchange resin, activated carbon, ion ceramic ball, far infrared ceramic ball, mineral balls and PP pad. Primarily, the filter helps to remove chlorine, zinc, copper, mercury and cadmium, disinfectants most commonly found in municipally treated water. It also removes 90% of lead and pollutants that give water an unpleasant odour or taste, organic and non-organic matter such as sand, silt and algae, and reduces free radicals, toxins and high negative ORP to effectively increase energy levels. The filter leaves in healthy minerals such as selenium and calcium, whilst making the water more alkaline by increasing its pH value between 8.5 and 10. The OXA is well catered for households with hard water, as the cartridges are designed to reduce limescale.
water – at an inexpensive price. It is much more cost effective and offers more savings as compared to constantly buying bottled water, which is also harmful for the environment since the plastic ends up in landfills. Thanks to a patented aeration design, the filter works fairly quickly and serves up water within minutes. An activated carbon core reduces chlorine and mercury which gives a foul taste and odour to tap water, while the ion exchange resin captures copper, zinc and cadmium. A built in mesh screen prevents black flecks. Although it reduces sediment, dust and dirt, The Brita’s capabilities are limited, so it should not be expected to remove heavy metals such as lead, VOCs or organic matter.
harmful substances from water, but also ionises it for a fresher, more natural taste. The filter features a composite six-stage cartridge, with an activated carbon shell, a nano-kinetic degradation fluxion, AS plastic and tourmaline ceramic to remove chlorine and heavy metals such as lead, cadmium, chromium and arsenic from water. It also decreases the concentration of organic pollutants such as mercury, manganese and nitrogen dioxide, whilst retarding growth and reproduction of microorganisms. All in all, the filter is able to remove up to 90% of potentially harmful substances within minutes.
layer made from non-woven materials, to filter out rust, dirt, silt and suspended solids. The next layer is an activated carbon fiber (ACF. from Japan, which has 10 times better adsorption than ordinary carbon, to reduce chlorine, VOCs and other contaminants. An ion exchange resin lowers water hardness by reducing limescale in tap water. Combined, the ACF and silver ion antibacterial technology inhibits up to 99% bacterial growth to ensure a clean water supply. Finally, a post filter, also made from non-woven materials, further removes other contaminants.
reviews of its great tasting water. Using patented BWT technology, the filter not only reduces chlorine, scale and certain heavy metals such as lead and copper, but also mineralises water with magnesium for a natural, fresh taste, and softer mouth feel. Magnesium deficiency is common among the population, with up to 70 percent of the adult population lacking this in their diet, and the BWT provides much needed magnesium in one’s diet. Thanks to the filter’s material, which contains silver, it provides antimicrobial protection and reduces polymeric beads or black flecks in the water.Another plus point is that no pre-soaking is required to activate the filter.
water, with a pre and post filter on the top and bottom, followed by a second layer of activated carbon which removes chlorine, heavy metals such as lead and arsenic, as well as contaminants. The third layer is where alkalisation happens, as the unit turns water to a pH of 8.5 – 10pH, whilst infusing beneficial calcium, potassium and magnesium. The fourth layer adds antioxidants, raising it from 200 – 400mv, while the fifth layer sports a hexagonal and micro clustered mechanism which creates smaller water clusters that are easily absorbed by the body. In addition, the Pure Green rids water of bacteria, E.coli and pesticides.
ionise tap water. When it works, its six-stage mineral carbon water filter removes chlorine, 65% fluoride and contaminants, whilst increasing pH value to over 7. Menawhile, tourmaline and other mineral stones add up to 20 trace minerals such as calcium, magnesium and potassium for softer, better tasting water that mimics natural stream water. However, the filter is not always consistent, with many users chiding its lackluster performance, the biggest point of frustration being its tendency to clog up. Optimally, it should take 15 to 30 minutes to filter. As it lacks a mesh to trap charcoal particles, black flecks may appear in the water.
mercury, benzene and limescale, in order to provide your household with clean water that is free from bad taste and odours. This makes it great for cooking, brewing tea or coffee, or watering houseplants and feeding to pets. It also softens hard water, and takes only a few minutes to filter.
patented ACF military technology, it reduces up to 97 % of chlorine, mercury, rust, sediment and suspended particles to produce clean water free from unpleasant colours, tastes and odours. The multi-staged cartridge consists of a nylon pre sediment filter which removes red rust, suspended solids and sediment, while a Swedish-made ion exchange resin reduces hardness, limescale and heavy metals such as mercury and lead.
water high in mercury content should consider this unit, as it uses MAXION filter technology to remove 95% of the element and 96% of trace levels of pharmaceuticals. In addition, the unique blend of activated carbon and ion exchange resin reduces bad odours and taste from chlorine, while leaving behind beneficial fluoride.The carbon filter is made from coconut shells that are heat treated with steam, producing small tunnels and spaces that provide a larger surface area to absorb and trap contaminants.
water evaporates to makes clouds. These clouds grow saturated with water which falls to the ground as rainwater and snow. This rainwater and snowmelt feed our fresh water supplies such as lakes and reservoirs.
