What Makes the Systems So Efficient

There are many types of filters available, including under counter, faucet, or whole house systems. Among all the types, the latter is the most effective and reliable for many reasons, some of which we will immediately list:

  • Extended action – While the other types of filters only act on a certain water source, this system covers the entire house and delivers clean water at any faucet or shower. It is important that you use clean water for any purpose, including bathing, cooking, or with your appliances, and having it installed means all the water in your house will be clean and fresh.
  • Wide range of chemicals removed – These are complex systems that retain a wide range of water contaminants. The combination of cartridges and sometimes of other filtration systems like softeners or UV light maximizes the efficiency of these systems in removing a wide range of impurities from the water.
  • Limited maintenance – Having a filter installed in every kitchen or bathroom means that you will have to replace cartridges for each one so your maintenance work will be significant. On the other hand, having this system means you only have to replace one filter and less often since these systems can handle up to 1,000,000 gallons of water without needing a replacement. Less maintenance means less hassle.
  • Lower costs in the long run – Although the initial costs of the filtration system are higher, you will eventually limit your investments mainly because you won’t have to install multiple units. The maintenance and service costs of a single system will be lower than the ones implied by having many filters installed at home.

Health Benefits of Purified Water

It can be quite the investment if you spend your money on a top of the line model. But know that your money won’t be spent in vain, as there are a lot of health benefits that you will enjoy due to making this addition to your home. To find out what are the benefits that we are referring to, check out the following list:

  • The carcinogenic effects of drinking, cooking, inhaling, and bathing with chlorine-filled water will be greatly reduced.
  • Rashes and skin irritations won’t appear anymore due to the fact that chemicals like chlorine won’t exist in the process of washing your clothes.
  • Bathing with clean water greatly alleviates the symptoms of allergies and asthma due to the fact that the air is cleaner in the bathroom.
  • Your hair and skin will look a lot better due to the fact that you will be cleaning yourself using water that is free of all types of harmful contaminants.

How to Install The System

Have you just made the purchase and you want to save up some money by installing it yourself? Then you have come to the right place because we will give you all the information you need in the following lines for you to be able to do the procedure all by yourself, without the help of a professional. What’s best about doing this DIY project is the fact that you will feel even more satisfaction knowing that you are the one who has provided the entire family with clean water for drinking, cooking, and bathing.

Choose the perfect location

Before you proceed to install it, you have to think about the exact location where you want to place it. The ideal positioning is in a spot that is easily accessible to you, ensuring that you won’t struggle when the filters need to be changed. The best thing to do is to place it near the shut-off valve, by doing this ensuring that you will have an easy time turning the water on and off when you are doing maintenance work.

Drain the water from the system

Now that you have figured out what is the desired location, it is time to proceed with the installation steps. First of all, you must turn off the water supply to be able to work freely. When the water is cut off, from the lowest point in your home, you must open a faucet in order to release the pressure and drain the water that has remained in the system.

Cut the pipe following the template

All filtration kits come with a template that helps you mark the pipe for precise placement. If you have followed the previous steps, you already know where you want to install it, so all that you have to do now is go to that location and cut the pipe while following the template that is included in the package. As you use the pipe cutter, make sure that you make two cuts and remove the marked section. Next, with the help of a twist handle, tighten the cutter onto the pipe, and rotate it around the pipe while you continue to twist the handle. Do this procedure until the cutter cuts all the way through.

Attach the fittings

On one of the ends of the cut pipe, place a compression nut and slide the ferrule on. When you are done, repeat the procedure for the other end of the pipe. The instructions manual that comes with the product will further explain what needs to be done here in case you cannot handle the procedure with ease, so there is no need to worry that you might get stuck at this step.

Install the filter

To install it, position it on the water line, and let it temporarily hang between the ferrules. Next, tighten the compression nuts onto the fittings using your hands, and keep it straight and upright while doing so. The last step when it comes to the installation procedure is to take two wrenches and simultaneously tighten the fittings.

Turn the water on

The kit comes with a special handle that you can use to turn the inlet valve to various positions, like filter, bypass, and off. For you to turn the water on, what you must do is to slowly turn the water on at the main valve, and check for leaks. Use the special handle to turn the valve to the filter position, this being the moment when the filtration procedure commences.


Generally, these systems are supposed to run perfectly for years on end, especially in cases where maintenance requirements are met. However, there is always the possibility for something to go wrong, even a potential malfunction to appear, moment when the water you drink and use ceases to be filtered by the system and the health of all household members is unknowingly put in danger.

Water Pressure Drop

Potential causes:

  • Missed filter replacement has caused the cartridges to become overused.
  • High sediment content in the water that runs through the pipes has caused the cartridges to clog.

Solution: Most likely, a simple replacement of the old cartridges with new ones will fix the issue, restoring the initial pressure of the system. However, if this doesn’t solve the problem, it might mean that the sediments in the water have a higher micron rating than the sediment filter of the system. What you should do in this case is to replace the sediment filtration media with one that has a higher micron rating.

Bad Smell/Taste of Filtered Water

Potential causes:

  • Filter replacement has not been performed on time.
  • Water contamination issues that overwhelm the system and its capabilities.
  • The system cannot handle the types of contaminants present in the water.

Solution: Evidently, your first course of action should be to replace the cartridges in the system with new ones. If the problem does not cease and you test the water to see that certain contaminant levels are still worryingly high, you can either replace the system as a whole with a new one that can tackle the issue at hand, or you can boil the water and let it cool before drinking it to ensure that the remaining impurities don’t threaten your health.

Brands We Recommend You Purchase From

Since the water filtration market is filled with a variety of products that you can purchase, your task of finding the right model to go with will be made a lot harder than you would expect. To make your search for the best easier, we will list the top brands in the following lines.

  1. Aquasana

Aquasana is undoubtedly the leading manufacturer on the market as it produces only NSF certified systems that reduce most common contaminants found in drinking water. The high performance of the products that this brand distributes and the fact that it is a dependable company when it comes to customer support is what helped make it the market leader. Furthermore, all systems produced by Aquasana are manufactured with the safety of the environment in mind, the components being engineered for minimal waste.

  1. Pelican Water Systems

Pelican Water Systems is another respected brand that produces high-end systems and that we recommend you purchase from. This company produces a wide variety of filters for all types of living situations, like houses, apartments, RVs, condos, boats, and more. The cutting-edge technology used in the manufacturing process of the products is what gives the Pelican Water Systems company its success, these products being at the top of the market when it comes to their performance.

  1. Crystal Quest

With an experience of over 30 years in this market, Crystal Quest is one of the companies which is noticeably concerned with the quality of the water we drink and use for mundane activities. Providing a large array of water purifying systems to choose between, regardless of the problem you are faced with, whether it is hard water that you want to be softened or contaminated water that you want to be cleaned, you are bound to find a perfect selection when purchasing from Crystal Quest.


How long does the installation process take?

If you call in a professional for the installation process, it will not take longer than 1 hour for the system to be in place and up and running. However, if you take matters into your own hands, the duration of the installation process depends on your speed and wit when it comes to DIY installation tasks.

How can I be sure that it is what I need?

More or less, we all could benefit from installing a whole-house system. What makes us so convinced about this statement is the fact that the system’s role is an essential one – cleaning the water that runs through your pipes of impurities. As the system removes impurities before the water reaches the end of its destination, you will benefit not only from clean drinking water but clean cooking and bathing water as well.

What are the common water issues resolved by the system?

The answer to this question depends on the filtration media that come with the systems. Generally, high-end models soften hard water, get rid of bacteria and germs, reduce chlorine levels, and eliminate most types of contaminants. For a clear answer, check the product’s spec sheet.

Does the number of filtration stages the water is passed through matter?

While the number of filtration stages does play an important role as it shows through how many layers of filtration media the water is passed before it reaches your glass, it is more important to see what type of media is used during the stages. To put it in simpler words, quality tops quantity when it comes to filtration efficiency.

What role does UV sterilization play?

An extra option which all systems should come with, UV sterilization tends to destroy bacteria, germs, and viruses that linger in the water you consume. Thus, not only will the water be free of the common contaminants which include fluorine, chlorine, lead, iron, and so on, but it will be so pure and free of any harmful contents and organisms that even the baby or child will safely hydrate with it.


As you have reached this point in the article, it is already more than obvious why our top pick was the Aquasana Rhino. It might be a hearty investment upfront, but it more than makes up for the initial cost as time passes. Furthermore, it is hard to top its performance when it comes to water filtration. What makes us so convinced are its 97% contaminant removal success rate, the 100 PSI operating pressure, the 10-year lifespan of the tank, as well as the fact that it can tend to destroy a plethora of contaminants. Of course, our other two top entries are not to be neglected either as the Pelican PC1000 boasts a great flow rate of 15 gallons per minute, while the Crystal Quest Eagle has an impressive 99.9% success rate when it comes to removing whatever pollutants lurk in your tap water.
