How to Choose A Whole House Water Filtration 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.

There are many things to take into consideration when choosing the whole house water filtration system that is right for you. Once you make the decision that this is the water filtration system that is right for you, we can help you choose what brand, model and type will supply your needs.

Water Types

What type of water do you have? That is probably the most overlooked question yet it is also the most common problem you need to address when seeking a filtration system for your home. Some systems only remove basic elements such as chlorine, rust and dirt. Others may remove all of those and trace minerals, harmful contaminant such as lead while others may help remove mercury, fluorides and much more.

Whether you have well water, city water or other type of water system, you want to be sure that all the pollutants that can be removed are missing from your water supply after filtration. Well water and some other water supplies such as cisterns and creek banked sump pumps often contain sediments such as dirt, small insects and leaf/grass particles. City water contains chlorine which is added due to government and environmental laws. All water supplies could contain lead, copper or other contaminants from old pipes and bacteria.

Understanding what types of water you have will help you to choose the system that will protect you and your family best. Most whole house water filtration systems include several stages for filtering your water. Each stage will remove specific types of contaminants and are equally important. How many stages you need will be dependent on what type of water you have. Water types vary from place to place and the water type you have may not be exactly like that of your neighbor.

To learn what kind of water is in your water supply, have it tested for a full list of contaminants or a simple test kit you do yourself will give you the basics. Even though millions get their water from the same source when they use city water, the pipes and other access points can often create variances in the contamination.

Simple stage whole water filtration systems are designed to remove the larger heavy sediments such as dirt, rust, leaves, algae and debris. Secondary stage sometimes called two stage are best suited to remove the heavy sediments and some specific chemicals such as chlorine. Triple stage systems remove all of the above but also remove other contaminants such as mercury, limes, some pesticides and lead. Larger multi-stage variables are available and can even remove some toxins and bacteria.

This is why knowing what type of water you have is so important. Unless you know, you will not fully comprehend which type of system you need to remove all of the harmful contaminants in your water.

System Maintenance

From installation to replacement, there are factors you must consider when buying a whole house filtration system.

1. Size if the unit - will it fit in the space available?

2. How hard is it to install - can you do it yourself or do you need to call a plumber?

3. Will working parts need maintained or changed and how often?

4. Is this maintenance do-able by you or does it require professional maintenance?

5. What, if any, guarantees or warranties does the system have?

6. How often is the normal time for need of full-replacement?

Size of the Unit? Some units are quite small and consist of a single filter while those with multi-stages are larger and require more space.

Installation of most units, especially the single filter units, could be done by you if you are the handyman type. Most would opt for a plumber to do the install unless they have “a friend” who is handy and knows what they are doing. The actual install and initial checking should only take a few hours for a regular installation.

How often will it need maintenance and can you do it? Most will opt for a plumber just because they are not handy. The handy-dandy do-it-yourselves could do most common maintenance repairs. The most common maintenance being changing filters.

Warranties and guarantees? These will vary by brand, type and even by the plumber or person who does the installation. Some plumbers may actually offer more guarantees and/or warranties than are issued with the new system.

How long before I need to do a total replacement? This varies by brand and by type. Many last for years when properly maintained. Some could last more than ten years. The latter tend to be more expensive but in comparison to a system which is good only for a few years and very limited numbers of gallons filtered before replacements or wear out, in the long run… these are often the best deals.

System Features

he 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.

Unlike on the tap filter systems, most often the whole house water filtration system will be attached the main water line into the home. Looks is not a priority and most systems are very similar while differences in the number of filtering stages may apply.

Most systems have auto shut-off and reset features built into the system. The auto shut-off features will warn when time to replace filters and possible leaks. Multi-stage systems often color code the filters and most will supply tool kits to make it easier to maintain your system.

A very few have an extra feature not common in the general groups. These have an extra “tube”, not really a filter which will re-add some beneficial chemicals “back into” the water.

If you are not on city water or have a chlorinating system already on your water supply, you may want the UV layer systems which help to kill microscopic organisms in your water.

Many whole house water filtration systems are adapted for connection to your ice-makers built into your refrigerators.


Unlike pitcher filters, performance is not based on how fast your whole home water filtration will filter a gallon of water but is based on how much water it will purify at a steady stream rate of flow (gallons per day). Along with the GPD rate, temperature is often a factor on the optimal operation of your system. You may need to add a pump or booster to your water intake “before” the system to help control the water pressure and temperature for your systems requirements.

Purity ratio is also a performance factor. The best systems are the ones that remove the most contaminants and are the higher percentages of purity. A system that performs a 95% purity is better than one that is 90%. 99% is difficult to achieve but some will claim this and higher.

Reverse osmosis systems may re-add basic minerals back to your water to raise the pH levels. Suggested levels are 6.9 to 7.5 pH.

The Cost Factor

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.

The first thing everyone looks at is the price. It makes sense to most that it is the most important factor. When you take into consideration the other factors, though, it is not the most important but is equally as important as the other factors. Some whole water filtration systems are a few hundred dollars while others are well over a thousand dollars in price. Immediately, most would say the best value would be the lowest price.

The problem with this type of thinking when it comes to your family’s health and your water supply needs, is that the cheapest may only be a single stage type which only removes sediments and must have filters changed on a monthly or bi-monthly basis and full replacement every two or three years. While the more expensive units are meant to remove most known contaminants, re-add beneficial trace minerals and require filter changes once or twice a year and full replacement in 5 to as many as 10 years.

When you figure in the shipping and handling of the system, cost of plumbers to change filters, systems and the cost of the number of systems used in the longest amount of time, often the best deal is really a more expensive initial cost whole water filtration system. When you also factor in your time and the flow rates and even the percentage of purity, initial costs are often offset by the time, later costs for maintenance and the benefits to you and your family’s health and well-being.

That doesn’t mean you should automatically choose the most expensive and not try to save money. There are many good mid-priced systems that will give you great features, better price and most reliable long-lasting service.

Final Verdict

When it comes to city water, most would be fine purchasing the small single or two-stage systems. If you have a well or other hard water source such as a cistern where the water may remain in a semi-stagnant or highly metallic containment, then you may want a combination of sedimentary filters and carbon filters in multi-stages. Water with heavy mineral content might require two sediment filters where a high chemical content water would require two or more carbon filters. If you are concerned about pesticides and other residual toxins then a system that offers the CTO carbon block or the thin membrane filtering system to stop bacteria and other contaminants. A UV lamp system that kills salmonella, e-coli and more would be necessary for those who are pumping their water from ponds and riverbanks as is often the case in the farmlands and out of town areas. The final verdict is actually simple. Test your water and determine what you need then compare the types for the best features and benefits for your water supply and then compare pricing. Remember even your neighbor’s water supply may test differently than yours.You may take a look of  another blog on kitchen cookware
