Buying Guide – What to Look For in a Reverse Osmosis Filter System

A look at some of the filter systems available in online and offline stores shows that there are many types to choose from. You need to consider the efficiency of the filter system. The best ones are those that have been fitted with high grade filters to ensure that they produce more gallons of water in a shorter period. Usually, the output is determined by the size of the system and not just the efficiency of filter systems. It also is important to choose systems that are not prone to leakages. If you talk to anyone who has been using water filters for long, they will tell you that after several years, the filter housing gets worn out. This is because it is subjected to constant pressure when in use. In addition to that, several routine maintenance take a toll on its strength and therefore, breakages and leakages occur. You can easily avoid this by choosing a filter that has a strong housing. For instance, while there are those that have a plastic housing, others have stronger ones.
It also is important to think about water wastage when buying a reverse osmosis filter system. The best systems are those that have been fitted with regulators to control both the pressure and the amount of water that flows through the filters. This way, you can control the amount of water to be filtered based on your daily consumption. It is the perfect way to reduce your bills while getting clean water at the same time. In addition to that, you should look for a system that is user-friendly. Even though you want more features, it will be useless if you find a system that makes everything too complicated for you. Whether you are thinking about routine maintenance or just daily use, make sure that you know what to do with the system. The best thing is that most of them come with user manuals and therefore, you should never find it too difficult to use them.

Types of Water Filters

Although reverse osmosis is incredibly popular, there are various other types of filters that can be used to purify water. They range from simple methods that can easily be improvised at home to the most complex ones used by big companies. For instance, many people across the world still use the simple active charcoal or carbon filters. These types use the power of activated charcoal to remove every type of dissolved inorganic solids. You can easily set up such a system in your house especially if you do not have access to the better types. Other types include ceramic filters, cartridge filtration, ion exchange resins, and ultraviolet sterilizers. There also are people who prefer to use combination units. In such a setup, various water filtration techniques are used in order to come up with the most effective way of filtering water. Are you wondering which one will suit you? You do not have to. Your choice should simply be determined by your own unique needs. At the end of the day, the most important thing is for you to get clean water.
Among all these water filtration processes, there is no doubt that reverse osmosis filtration is the most effective one when it comes to getting rid of total dissolved solids. These systems are fitted with various filters to ensure that the output consists of water that if one hundred percent purified. The fact that they have been approved both by environmentalists and leading scientific research companies shows how effective they can be. It also is easy to install these systems at home. Unlike the other types that would require a lot of time, reverse osmosis filters only require you to know where to drill the holes and fit them,. Once you are done, there is nothing else you will be required to do unless it is time to change the filters of fix a few things. Even when that time comes, you do not have to worry about anything because getting rid of total dissolved units from water is quite a simple process.

What is Total Dissolved Solids (TDS)

Total dissolved solids are majorly inorganic salts that are dissolved in water. They include magnesium, calcium, potassium, chlorides, sodium, bicarbonates, and sulfates. These salts usually come from natural sources and therefore, it is difficult to stop them from getting into water. Such sources include urban run-offs, sewage, wastewater from industries, and chemicals that are used to treat water. The piping or any other hardware used to supply water can also be a source of total dissolved solids. In most countries, industrial action has been cited as one of the biggest sources of TDS. For those who live near the costs, seawater intrusion can also lead to the occurrence of these solids. In agricultural fields, the use of sprays and fertilizers can also lead to water contamination. The only solution is to ensure that the water is properly filtered before it can be used especially for drinking. With a good reverse osmosis filter system, you have all that you need to ensure that you have safe drinking water in your house.
Best Reverse Osmosis Filter Systems
In a nutshell, total dissolved solids are the accumulation of positively charged and negatively charged ions in water. These ions can react to completely change the characteristics of water. For instance, you may notice that the water has an unusual smell, has some coloring, and has some unusual taste too. The most affected water is that drawn from sources such as wells, springs, rivers, and general natural sources. These are more prone to intrusion by external agents that contain inorganic salts. Sometimes, companies and other health organizations take TDS tests on ware before allowing people to use it. The results of a TDS test are a qualitative measure of the ions although it does not indicate the nature or the relationship between these ions. Things such as a salty taste, elevated hardness, and corrosiveness are just some of the effects of total dissolved solids. Since everyone likes clean water that tastes great and has no health risks, these solids need to be removed from water before it can be used. A filter system is designed to separate the salts from water.

Do I need an Air Gap Faucet?

An air gap faucet is meant to offer a siphon break in the drain line of an under sink that has a reverse osmosis system. There are homes that only have a filter on the drain line and not a reverse osmosis system. For such cases, an air gap faucet will not be necessary. This is because there is no drain connection in the first place. Many people get confused when they find out that there are drain lines that require air gap faucets while others do not. Even when you are not a professional plumber, you can easily see that there is no drain connection in a system that has no reverse osmosis. However, most homes do have reverse osmosis systems and therefore, it is important for them to know if they really need this kind of faucet. In a situation where a reverse osmosis unit is fitted, an air gap faucet may or may not be needed.
Best Reverse Osmosis Filter Systems
First, you need to understand that the purpose of this faucet is to ensure that water from a stopped-up sink does not get sucked back into your reverse osmosis unit through the drain connection. The faucet has a trough built in its base where this water gets sucked through the use of air. The water then drops on the other side of the faucet and is directed into another drain pipe. Because of this mechanism, the faucet requires three tubes as opposed to the one that is usually needed. Because of this, the faucet requires a wider hole for installation in the sink and also has a wider base. The installation may also be more complicated that you think. As to whether or not you need an air gap faucet, it depends on your system type. However, whenever possible, you should ensure that it is fitted because it gives that extra assurance that not dirty water will be sucked back into the reverse osmosis system. It is more necessary if you filter a lot of water every day because you will require more accuracy.

Reverse Osmosis Water Output

There are various factors that affect the output of a reverse osmosis filter system. Most of the time, different brands have different output capacities. However, the conditions under which they are used and the type of total dissolved solids being filtered also determine the output. For instance, water that has too much chlorine may take longer to purify meaning that the output will be low. On the other hand, water that only has a few contaminants will pass through the filters faster. When buying these systems, you may want to look at the number of filters that they have. You also should look at their size. This is because the two directly determine how much water can go through the system at any given time. Inquire from the supplier about these facts before setting for one of the systems in order to avoid some of the confusions that most customers find themselves in.
Apart from the features of a reverse osmosis filter system, external factors are also likely to determine the output. Experts say that temperatures have a direct effect on the output speed. If you are filtering warm water, the filters will be enlarged and therefore, the water will most likely flow through them faster. You also should look at things such as the pressure in your tank and the types of pipes used. Also consider using faucets that allow for more output if you want to filter water fast. It is more important if there are lots of people who want to use the water. For instance, if you are using the system in a busy restaurant, you have no option but to go for one that has a higher output. The best part is that no matter how much water you want, you will always find a system that can meet your needs.

PH Values in the Feed Water

Reverse osmosis systems are meant to reduce the PH values in water. However, there may not always be a noticeable difference based on various factors. During the filtration process, slats and other elements that cause acidity are removed and therefore, it is expected that the output should have lower PH values than the feeder water. The type of water being filtered determines the kind of PH values to be expected in the output. Environmental factors often determine the acidity or alkalinity of water and therefore, you should expect the difference in PH volumes to vary from one place to another. Rather than worrying about the PH volumes, you should be more concerned with the effectiveness of your reverse osmosis system. Once you are assured that the filters are up to the task, you can be sure that the output water will be safe for drinking regardless of the PH values in the feeder water.
Best Reverse Osmosis Filter Systems
The levels of gases in your local water supply also determine PH values. For instance, if there is too much CO2 in your area, you can expect it to have an effect on the acidity of water. This also means that there will have to be through filtration in cases where these gases are too much. However, there is nothing to worry about here because regardless of the environment that you live in, you will always find a reverse osmosis system that perfectly filters all the contaminants to make water suitable for human consumption. The only thing you should be thinking about should be how to get the best system from among the many that you are likely to find in the stores.

How do Reverse Osmosis Systems Work?

Reverse osmosis is a simple and straightforward process used to filter water. The system uses pressure to push water molecules through a filter membrane in order to remove contaminants. There usually are various semi-permeable membranes that act as filters during the process. As the contaminants are removed from water and flushed away, they leave a clean output that is safe for drinking. There are over 65 contaminants that can be found in water and scientists say that reverse osmosis can remove up to 95% of them. The water is pushed through a sediment filter, carbon filter, reverse osmosis membrane, and a polishing filter before finally coming out of the system. The speed at which the system removes these contaminants depends on various factors including the brand, type of water and local temperatures.
