It features 1” input and output ports, and it is easy to install and use. This system utilizes a 2-stage process for filtration, and it can remove up to 98% of chlorine, sediment, VOCs, and other contaminants that could be causing problems with your water. The sediment filter can help to reduce pressure loss, and it can help to ensure fewer clogs. The carbon block, which uses coconut shell carbon and compact fabrication improves the efficiency of the filter and helps with longevity.

The system has a 50,000-gallon capacity before a filter will need to be replaced. The filters are typically capable of providing from six months to a year of clean water for a family of four. Of course, this can vary based on just how much water you are going to be using and running through the filter.

The system is preassembled, and DIY installation is possible for those who want to tackle the installation on their own. The system is a good option as a point of entry filtration system, and it can work well for a home or a business whether you are getting city water or well water that has can with chlorine. The filters that are used for this unit will measure 4.5” x 10”.

Aquasana Premium Rhino

The Aquasana filter system is a high-quality option that can remove 97% of chlorine for 1,000,000 gallons of water. The system has a dual tank design, which means that the water will spend more time in contact with the media that help to clear away contaminants. This is a long-lasting system that can provide great tasting water in all areas of the home.

This version of the system comes with a salt-free water conditioner, which can help reduce the scale buildup on the internal pipes and plumbing. Since it does not use salt, as many water softener systems do, it could be a good option for those who may be on a low-salt diet. An optional upgrade is a professional installation kit, which includes bypass valves, brass fittings, and bend supports. It is also possible to get UV filtration for the system if desired, which can help to remove a range of viruses from the water.

The system is simple to install; it is durable and long-lasting. Many homes using this system will not need to have a replacement for up to 10 years. It could be a good option for those who want a simple way to get better tasting, healthier water in their home.

Express Water Heavy Metal Whole House Water Filter

The 3-stage system from Express Water is another popular choice for whole house water filters thanks to its stellar design. The filter can remove a wide range of contaminants from the water, including chlorine, rust, lead, pesticides, sand, viruses, fungi, silt, aluminum, herbicides, and much more.

The system features a precise first stage, so you can monitor the system and know when you need to replace the filters. This makes it easy to know when replacements are needed, so you can have them ordered before they are required. The filters are easy to replace, as well, so you will not have to spend a lot of time on maintenance when you have this system.

In the first stage, sediment is filtered from the water. Here is where rust, dirt, sand, and similar contaminants are removed from the system. At the second stage is the KDF or Kinetic Degradation Filter. This will capture contaminants like lead, arsenic, viruses, algae, mercury, and chlorine. At the third stage is the Activated Carbon Block, or ACB, filter. This also captures chlorine that may have made its way through the second stage. It also removes pesticides, chemicals, and similar contaminants.

The system has heavy-duty construction and is made from food-grade materials. All of the components in the system meet the NSF/ANSI standards. The housings utilize high-capacity flow connectors, and the connections are rated for up to 0.25 gallons per second at 45-80 psi. Each of the sets of filters will be good for up to 100,000 gallons, which will generally mean they only need to be replaced every six months to a year. Of course, it will depend on the amount of water being used.

iSpring WGB22B

The system features a gradient 2-stage system that will help to remove a range of contaminants like chlorine, rust, VOCs, and more. It features a 1” NPT inlet and outlet and can allow for water flow up to 15 gallons per minute. You can install this system at the main water supply, and it will be able to treat all of the water that is used in the home. Keep in mind that this is not a reverse osmosis system, so it will not remove all of the TDS from the water. This means that it can still keep the healthy minerals in the water.

The first stage of this system can achieve filtration to five microns, while the second stage is a carbon block filter that uses coconut shell carbon. The system has a 100,000-gallon capacity, and it should be capable of removing up to 95% of the contaminants that could be causing issues with your water. In most cases, the filter will last for about a year, but this will depend on the amount of water that is being used in the home. The system tends to work best for those who have lightly chlorinated and lightly contaminated water, such as those that you would get from a municipal water source. This is not the best filter option for those who are using well water.

3M AquaPure Model AP903

3M is a popular company that makes different types of products, including water filtration systems. The system features a noncorrosive stainless steel head; a carbon filter media that will reduce chlorine taste and odor from the water. It allows for a high flow rate of 20 gallons of filtered water per minute. Another one of the benefits of the system is the fact that it has a simple twist-off system for replacing the cartridge. This means you will not need to have any special tools or anything.

Something important to note about this system is that the manufacturer recommends that you also have a prefilter system in place in front of the unit. This will help to trap dirt and rust. The filters for the system have a 100,000 capacity, which should be able to last most homes for six months to a year depending on the amount of water that is being used.


You will find that this is a very different option from most of the others on this list. This system is an ultraviolet water purifier sterilizer filter. The housing is a 40W 37.2” x 2.5” stainless steel chamber that can allow for a flow rate of 12 gallons per minute. The installation is quite simple, and you should not need to have a plumber. It will need assembly when it arrives, but assembly is also easy. Keep in mind that horizontal installation for this system is recommended from the manufacturer.

The system does not make use of any chemicals, which means it is environmentally friendly. It also means that the PH of the water will stay the same, and there will be no negative changes to the taste or odor of the water. The UV disinfection process degrades the DNA of any organisms that might be in the water, which will ensure that anything in the water is dead and harmless to those who drink it. It can reduce the number of bacteria and microbes in the water by 99.99%.

This doesn’t have a typical filter that will need to be replaced. However, the lamp will need to be replaced on an annual basis. Also, the quartz sleeve will need to be cleaned about every six months and replaced every two years. Because this is only a UV system, you will likely want to have pretreatment and another filter system in front of this system.

Aquasana Rhino

The system is serviced to remove more than 97% of the chlorine in tap water, and it can reduce the other harmful elements that might be in the water, such as herbicides, pesticides, rust, sediment, industrial solvents, and more. You will also find that the overall durability and design of the system make it a solid choice for those who are looking for a system that will last. The filters themselves have a 300,000-gallon filtration capacity. The dual tank design helps to trap more contaminants, and it can prevent the system from clogging and needing to be fixed or needing to have a filter replaced prematurely.

When you use SimplySoft with the system, you will find that it does not remove essential minerals from the water, and it does not put additional salt or chemicals into the water. Also, it does not require electricity, as you will often find with water softener systems that are part of a water filtration system. Overall, it is a simple system that will not require very much at all in the way of maintenance. Replacing the filters and components when needed is all you will need to do. You don’t need to worry about continually replacing salt, as you would with a standard water softener system.

Filtersmart 1-4 Bath Filter System and Softener Combo

The filter system seen here is a good option for households that have between one and four bathrooms. Also, being a water filter, it does double duty as a water softener like several of the other options on this list. The system has a pre-sediment filtration that will help to remove the more significant bits of rust, debris, and silt from the water. The system also has granulated activated carbon, which can remove chlorine and help to improve the overall taste and smell of the water.

The water conditioner for the system is salt-free, so it can be a good option for those who do not want or need the added sodium in their water that some softener systems provide. It could be suitable for those who are on a low salt diet. The media used for the softener will help to suspend hard water particles so they will not create limescale in your home.

The system can be installed quickly, inside or outside of the home. You will only have to change the filter every eight to 10 months or so. There is no other maintenance that you will need to worry about with the system.

iSpring RCS5T

The system will work well for residences, as well as for light commercial use. The system has five different stages of filtration and can produce up to 500 filtered gallons per day. The system can remove up to 99% of more than 1,000 different types of pollutants, such as lead, arsenic, pesticides, and pathogens.

It also features a pressure gauge to make monitoring the system easy.

The system offers fast flow filtration, which can provide up to 0.25 gallons per second. You can remove heavy metals and other contaminants and get the healthy, clean water that you and your family need.

What is a Whole House Water Filter?

The whole house water filter is far different from the filters that many people use directly on their faucets. These whole house filters, as the name suggests, are generally able to provide you with all of the filtration needed for the entire house. They are often called point of entry systems, as they are placed close to the spot where the water comes into the home. Placing the system before the water heater will ensure that both the cold and the hot water are treated. When you have one of these systems installed, it will mean that all of the water in your house, whether it is the kitchen or one of the bathrooms, will be fully filtered.

The filters are meant to remove particles of varying sizes, usually down to around the five-micron level. There are typically many different stages with the various filters, as you have seen. Different systems and setups will, of course, have a different number of stages and types of filter. However, the basic principles of how they work are going to be the same. The filter will be attached to the main line, as mentioned above, and the water will then first go into what is called a sediment prefilter. This filter will remove the larger particles in the water. This might include rust, sand, silt, and other types of sediment that might be in the water supply.

The sediment prefilter is also helpful in ensuring that the other filters in the system last longer without needing to be replaced. If there were no sediment prefilter on the water filtration system, it would mean that those other filters have a higher risk of becoming clogged. Naturally, that would mean more filter changes, which could get expensive.

Once the water passes through the first filter to remove the sediment, it will move on to the other filters in the setup. It will often include an activated carbon filter. Most consider the activated carbon to be the most important filter in the setup since it will remove the bulk of the contaminants in the water. These filters will have a porous surface, and through the process of adsorption, attract contaminants to the filter. It can remove volatile organic compounds, chlorine, remaining sediment, and more. This is the part of the whole house water filter system that will ensure that there is not any terrible scent or taste in the water.

The water will then typically go through a copper-zinc and mineral filter, which will remove even more contaminants from the water. It can help to remove heavy metals, bacteria, and any of the chlorine that might remain. This filter can also help to reduce scale in the water.

In the case of some of the systems, including several on our list, the water will also pass through a softener system, which will remove the hardness of the water. There are several other potential options, as well. Different filters will have different stages and options available, and you might find that some need to have some additional filtration as a part of the setup to provide the best results. For example, the UV filters tend to work best when there are other filters, such as a sediment filter and an activated carbon filter, in front of it.

Benefits of Using a Whole House Water Filter

Do you need to have a whole house water filter? While some choose not to have any filtration system in their home, they will soon find that it can cause some problems for them. It will mean that they are getting water that is either right from a well or from the city that does not have all of the treatment that it should have. This can lead to water that smells and tastes terrible, and it could even mean that there are dangerous contaminants that make their way right into your drinking water.

If you have chlorinated water, you are going to taste chlorine when you drink from the faucet. While chlorine can disinfect the water, it is not healthy for you to drink. It can also have negative effects on your hair and your skin. If you are washing with chlorinated water, it can make the skin and the hair dry. Think about how you feel after getting out of a chlorinated pool. You don’t want to have chlorine on your body if you don’t have to, and you certainly do not want to be drinking it.

Using a whole house water filter will help immensely. It will ensure that you can get the clean water that you and your family need, and it is also good for the environment. Even though you have to change out the filters occasionally, it is much greener than drinking water out of plastic bottles all the time. Also, a filtration system does not create any wastewater. The water that goes into it will be the same amount of water that comes out.

Most homes and many businesses will benefit from using one of these water filter systems. If you have chlorinated water, if your water has a high concentration of bacteria, if it is cloudy or has sediment in it, or if it has a strange taste or smell, you will benefit from proper filtration.

Do You Need a Water Softener System if You Have a Filter?

One of the common questions that come up when talking about home water filters is water softener systems. There is some confusion surrounding them, and it is essential to realize that they are not the same thing. Therefore, if you not only want to remove contaminants from your water, but you also want to remove hard water problems, you will need to have both a filter and a softener system. As you have seen on the list above, it is possible to find some filtration systems that also have a softener system attached to it. These could be a good choice for those who want to have a single system. Those who already have a softener system will want to choose one of the options that do not have water conditioning and softening already added.

Important Things to Consider When Choosing Your Whole House Water Filter

You know that you want to have a water filter, and you are starting to narrow your decision. However, you need a little more guidance and want to know what some of the most important things to consider are when you are making your choice. Let’s look at some of the significant elements.

First, you will want to make sure that you can choose a water filter that can provide you with a substantial amount of filtered water per minute, such as those listed above. If you have a lower quality filter that can produce a couple of gallons a minute, your water pressure is going to be terrible. You need to have a system that can provide you with the flow you need for the entire home.

Also, you will want to think about the filter types that come with the system. Will it be enough to provide you with the clear water you need, or will you need to add anything else to your setup. Does the unit have an activated carbon filter and a copper-zinc mineral filter? Should you also get a UV filter? Think about what you need and what you want from your filter before you make your decision.

You should also think about the longevity of the filters for the system and compare that with the consumption of water in your home. You want to choose a filter that you will only have to change our once or twice a year at most. Stay away from low-quality filters that will need to be replaced every month or so. Not only will it be a hassle, but it can become expensive.

Tips for Installation

Installing a whole house water filter system might seem like a big and challenging job, but it is not as difficult as you might think. Many people who have a little DIY spirit and the right tools will be able to handle it on their own, as you will see from the basic tips below. However, you might find that it is better to work with a professional for the installation if it is a little too intimidating for you. However, for those who will be able to handle it on their own, it is relatively simple. Even with the different types of systems, you will follow the same basic steps.

However, even though the guidelines below will provide you with a good idea of what you can expect, you will still want to make sure that you follow the instructions that come directly from the manufacturer for installation.

You will want to turn off the main water supply and drain the system, and then choose a location for the filter system. When you are selecting a location, you likely want it to be out of the way and near the area where the water comes into the home. However, since you will be changing out filters, you also want to make sure it is easy to reach.

Mark the spot, and then cut the pipe with the pipe cutter. You will install the compression nut and fittings, using Teflon tape for the fittings. Install the filter and make sure that it is facing the right direction. This means that the in and the out ports are facing the right direction. Turn off the filter’s inlet valve and then turn on the main water supply. You will want to check for leaks. If there aren’t any, you can then turn on the inlet valve on the filter and check for leaks again.

That is all there is to installing most systems. It shouldn’t take long to do at all. Just make sure that you have all of the right tools in place, and that you are confident before you begin.

Tips for Changing Out the Filter

While the systems tend to be very low maintenance, they will need to have their filters changed out occasionally. The process for changing the filters will vary from one model to the next, but there are quite a few similarities at the basic level. For example, you will want first to turn off the water filter’s inlet valve. Some of the systems have easy to remove and replace filters that will not require any tools. For others, you will need to have the proper wrench available to remove the filter. Put it in a bucket to contain any dripping water.

Clean out the inside of the system with a clean and dry cloth, add the new filter and tighten it up properly. Turn the inlet valve back on and then let the water run for about 10 minutes. This will give the filter time to activate. Once you do that, the filter is good to go until the next time it needs to replacement. As you can see, it is quite simple, and it should not take you more than a few minutes.

You should now have quite a bit more knowledge on what you should be looking for in your whole house water filtration system. You also have a list of the best options on the market today, so finding the perfect solution for your home should be easy. Find what you need today and improve the quality of your water.
