Best Reverse Osmosis System – Guide & Reviews

You may not be happy with the filter jug for various reasons such as bad odor, risks of residual chemicals, and unpleasant taste. Bottled water may combat all these issues, but is not a solution for daily water requirements. Isn’t it a good idea to employ the same technology that bottled water filtration uses to get a regular supply of healthy, tasty, and pure drinking water?

Reverse Osmosis (RO) is one such leading water filtration technologies that have emerged to be successful. The RO systems are based on reversing the natural direction of water flow. It makes the water flow from a concentrated to a dilute solution through a specialized filtering membrane. The systems have several stages of pre and post filters that purify the water.

The RO system is preferred because it filters the harmful chemicals like chlorine, total dissolved solids (TDS), organic pollutants and most of the other contaminants that are easily removed by the regular filters such as dirt, silt, dust, and other sediments.

How to Choose Reverse Osmosis System

How to choose an RO system that best suits your needs depends on multiple factors. Here are some of them that can help you to pick a good RO system.

Type of Water

The first consideration to select an RO system is the type of water that you wish to filter. Different RO systems efficiently filter tap water, water from well, be it hard or soft water.The resulting water need not be always assumed to be used for drinking or cooking. It may be for your aquarium or some laboratory use.

The type of contaminants that are present in the water differs from one place to another. The contaminants can include chlorine added by the water authorities before it is supplied, bacteria that may grow in still water, lead and rust from corroded pipes, dissolved solids, and sediments that can be added in any of these stages.

There are different stages in any RO system that purifies each of these types of contaminants. Carbon blocks are incorporated to filter out the sediments and other particulate matter. There are specific stages designed to remove the TDS and other minerals.

You can use some of the best tools to determine what types of contaminants are present in the water at your place. You can choose the RO system that can remove the specific contaminants. You may also seek help from your local authorities to find out the quality of water that reaches out to you.

Often the fourth stage is the actual reverse osmosis stage that has a sheet of the filter with fine perforations with pore dimensions as low as 0.0001 microns. It squeezes the solute contaminants and allows only the solvent water to pass through it. The semi-permeable membrane is known to be the heart of the RO system.

Maintenance required

The first task of the owner after buying the RO system is installation. The size of the RO systems varies from one model to another. There are light-weight, easy-to-fit models as well as strong and heavy-duty models. Again it depends on your requirements to choose one of them.

Some RO systems have simple architecture and can be installed easily with the help of the detailed manual. Some brands have YouTube videos to help customers. There are others which may need professional help to install and start using the RO system.

Some RO systems carry six stages while others have four. Although it is not mandatory to have bigger size as the filter stages increase, it can be considered as one of the indications. Some systems are known as countertop while others are under the sink. If the RO systems are designed to be compact, it can virtually fit any place.

Although many RO systems may advertise themselves to be maintenance-free, that may not be totally true. Like all other equipment, RO systems also need maintenance. The filters need to be changed regularly. The membrane should be replaced. These are the common maintenance that may be required. But there are more to add to the list as the RO system ages.

The life of the filters and membrane should be longer. Some systems provide six to twelve months life. The automatic shut-off, storage tank, faucet, and other connectors should be made of good quality material so that they last long. It should not require calling up technicians to fix issues such as leakage or clogs.

The ease of changing the filters is also a notable feature that may be considered while deciding on which RO system to buy. Some RO systems have easy push button facility while others may need plumbers to replace all the filter cartridges.

Features

The main features that you look for in an RO system will often reflect the effectiveness of the water filtration process and the ease of handling the system. There is no point in having a designer faucet if it does not provide water with a good flow rate.

The RO systems come in different color and designs. Looks may not be the priority but can be one of the attractive features. Nobody would want to have something that looks shabby in their kitchen cabinet or something that can ruin the reputation in front of clients.

Some of the minerals that may be required to be present in the water to make it healthy may get sometimes removed during reverse osmosis process.Re-mineralization is one of the advanced features where the purified water is added with essential minerals such as magnesium and calcium.

Automatic shut off, indicators that suggest when to change the filters, or any leakage in the system are some of the desirable features. Color coding of the filter cartridges helps easy replacement. Tool kit included in the set is also one of the useful additions to the RO system package.

UV layer may be required to protect from microbes in the water. But if you are supplied with chlorinated tap water, it may not be an absolute necessity.

The RO system provides water that is often used for drinking or cooking. It will be an icing on the cake if it has easy options to connect to refrigerator or ice maker.

Performance

A survey says a normal person needs half a gallon of water per day. There are capacities such as 50 GPD, 75 GPD, 90 GPD, and so on. Depending on your needs, you can choose the capacity of the RO system.

The capacity of removing TDS by RO systems are up to 99%.Measuring the purity of the resulting water may be difficult. Nevertheless, there are claims of producing 99.9% pure water by some of the RO systems based on the various contaminants it can remove and the conditions of the input water.

A specific range of pressure and temperature of the incoming water would be favorable for the RO system to work efficiently. If your water supply does not meet these requirements, you may have to use additional equipment such as boosters and pumps that can enhance the pressure and control the temperature.

The pH level of the water is said to be disturbed after reverse osmosis. Many RO systems re-mineralize and bring back the pH level to acceptable levels between 6.9 and 7.5.

The purified water flow rate is another important performance characteristic. The time taken to turning on the faucet and the purified water coming out of it should be as less as possible. There may be other defects such as clogs in the filters that may affect the flow rate.

Budget

The biggest constraint in choosing an RO system will be your budget. Even if you have a fairly high budget dedicated for an RO system, you will not prefer one which is not worth the money.

Apart from just the price of the RO system, you need to think about the installation costs, maintenance costs, and the cost involved in buying any accessories required for it. A good research for an hour can tell many tales about different RO systems in the market.

Some RO systems may require professional plumbers for installation and sometimes the company offer to send technicians to your doorsteps to install the RO system for free. Regular service may also be free for a certain period.

You need to include the cost of the filter cartridges that would fit the RO system. Some RO systems come with an additional set of filter cartridges. Also, check the cost of other parts like membrane or storage tank that may require being changed after specified period.

It would also be wise to check both online and in-shop costs of the RO systems. Although online costs are often cheaper, do not forget to add delivery charges and any other service tax when you buy online.

On a positive note, you get a decent RO system in the mid-range budget. There are RO systems that have been reviewed to be good value for money.

Which Type Of Reverse Osmosis System Is the Best?

As seen above, there are several types of reverse osmosis systems in the market. It would be difficult to name one of them as the best as each of them serves a different purpose. Depending on your requirements, you could choose one of these types and the best RO filter in that type.Here are a few categories that can be considered.

Different stages involved in the filtration process

There are three to nine stages of filtration in the RO systems. Typically residential RO systems have up to seven stages and nine stages may be required if the RO system is being used to produce more than just drinking water. Each stage is designed to remove a specific type of contaminant.

The three main stages include pre-filter to remove sediments and activated carbon filter to remove other chemicals causing bad odor and taste. As the number of stages increase, each stage is involved in removing specific type of contaminants such as particulate matter, sediments, chemicals, organic pollutants, bad taste, and odor.

Some stages are designed to add the minerals that may have been removed during RO process. The pH level of the water is balanced through alkalization. Calcium and magnesium are added in sufficient quantity to ensure the water is healthy and pure.

It may not be true that as the number of the stages increase, the quality of purification increases. But it only indicates a dedicated stage for purifying different types of contaminants. Additional stages such as remineralization are an obvious plus. When you know what kind of contaminants is present in the water supplied, it can be easier to choose the RO systems that suit you.

RO membrane

Depending on the presence of chlorine in the water, the RO systems can be selected. Two types of RO membranes are used in residential RO systems. Apart from this commercial RO membranes are also present that have higher capacities and cost little more.

Cellulose Triacetate (CTA) is that type of membrane that can filter chlorinated water with a capacity of producing up to 20 Gallons per day. Thin Film Composite (TFC) or Thin Film Material (TFM) can filter non-chlorinated water and has higher capacities of up to 150 Gallons per day. The standard low-pressure membrane has a spiral winding and is designed to fit the regular RO systems.

TFC membranes are more common than the CTA counterparts. But when TFC membrane is used, the pre-filter should have an active carbon to remove chlorine from the water. Otherwise, TFC membrane becomes susceptible to degradation.

The commercial RO membranes are capable of operating with an input water pressure in a range between 100psi and 225psi, unlike residential membranes which operate between 40 and 100psi. The commercial membranes are capable of treating sea and brackish water.

The membranes have a longer life depending on the pre-filters. If the pre-filters can protect the RO membrane by eliminating sediments and chemicals such as chlorine, the RO membrane can survive for longer. The pre-filters are often replaced every six months while the average life of RO membrane is about a year.

The RO membrane forms the heart of the reverse osmosis system. That means, the type of RO membrane should be able to purify the type of water that you input into the RO system.

Under the sink or countertop

Depending on where the RO systems can be installed, its portability, and the design, they can be categorized as under the sink and countertop RO systems.

Under the sink RO systems are installed under the sink as its name suggests.If the kitchen cabinet is too small, the consumers find a different location from where the water can be supplied easily. They have higher capacities and can be used for large families and commercial purposes. They cannot be portable easily but can be fixed in your kitchen or close to a water supply. They often do not store filtered water. But they filter the water once the faucet tap is opened and release the purified water. They may cost a little more than the countertop RO systems but are a reliable source of unlimited supply of purified water.

The countertop versions are often compact and are easily portable. They are easy to install and can be most useful for small families. They can be ideal if you are looking for a cost-effective and efficient RO system that can suffice your daily needs of drinking water. They may not be great for large families or commercial usage as it does not produce a large quantity of water.

Both the RO systems have different stages of filtration. They can have all other facilities such as carbon blocks, easily replaceable push-button filters, and remineralization processes. Depending on what amount of water that you require daily and where you would use the RO system, you can choose one of the above two types of RO systems.

Recommended Products

Home Master and APEC have ruled the industry for quite some time and are leaders in producing efficient RO systems. Both have tremendous experience and have earned patents for their technologies.
