A good value, this whole house water filter system is a great option for those on a budget. This combination system redirects your entire household’s raw water supply to a filter and softener to reduce calcium, rust, chlorine, and other contaminants.


The best water filters can remove harmful contaminants, allowing you to enjoy healthy, hydrated water from every source in your home.

What is a Whole-House Water Purifier?

A whole-house water filter works to ensure filtered water is available throughout the home. It supplies a household with clean, soft and better-smelling water for drinking, bathing and washing clothes and dishes. This type of filtration system eliminates harmful contaminants like metals, chlorine, rust and bacteria to improve the quality of your water supply.

A good water filter system can also reduce hardness of your water by reducing mineral concentrations in it. This makes your pipes less likely to clog and can help extend the lifespan of your appliances, while making your skin and hair healthier.

Different whole house filtration systems have different capabilities. Some of them are designed to remove contaminants such as radon, arsenic, fluoride, chloramines and cyanide from your water. Others are designed to filter organic matter and volatile organic compounds (VOCs) from your water. Some are even designed to reduce dissolved iron, which can make your water taste metallic and unpleasant.

If your city or well water contains high levels of contaminants, a whole-house water filter is the right choice. It filters incoming water as soon as it enters your plumbing system to prevent these harmful substances from entering your home. This type of filtration system can come in 1-stage, 2-stage and 3-stage options. The most advanced models can even include a water softener to reduce hardness of your water. iSpring’s 3-Stage Whole House Water Filtration System is a great example of a feature-packed filter. It’s easy to install and requires minimal maintenance.

How Does a Whole-House Water Purifier Work?

A whole-house water filter system treats all the water coming into your home, which means that every faucet, shower and appliance dispenses clean, filtered water. These systems — also called point-of-entry (POE) filters — work differently from products like shower and undersink water filters, which target the specific areas where they are installed.

Most whole house water filtration systems use replaceable cartridges to filter out contaminants from all sources of your household water, including sewage and municipal drinking water. These cartridges, which are available in a variety of sizes and styles to fit your specific needs, include sediment, heavy metal, organic chemical and bacterial filter media that hold NSF certifications.

If your main water quality concern is hardness – which causes calcium and magnesium to build up on fixtures and pipes — then you should look for a system that includes a water softener as part of its filtration. These systems use ion-exchange technology to remove the minerals that cause scale buildup by replacing them with sodium molecules.

If your local municipal water supply contains chlorine and other chemicals that make your water taste unpleasant, then you may want to invest in a carbon-based filter for your whole house. These types of filters can reduce chlorine taste and odor, as well as organic pollutants like pesticides and herbicides. They can also reduce harmful heavy metals, such as iron and hydrogen sulfide, from your water.

What are the Benefits of Using a Whole-House Water Purifier?

A water filtration system ensures that you and your family have access to clean, healthy water. It eliminates the need for buying bottled water and allows you to use your faucets and showerheads with confidence. This will save you money, reduce the number of harmful contaminants in your body, and help protect your appliances from clogging.

A whole house water filter can also improve the taste and smell of your tap water. It will remove contaminants and impurities that cause unpleasant odors, which can be a major turn-off for some people. The clean, fresh-tasting water may even encourage you and your family to drink more water throughout the day.

In addition, a whole house water filter system can prevent the build-up of hard minerals in your pipes and water-using appliances. This can extend the lifespan of your appliances and improve the performance of your sinks, showerheads, and washing machines.

Unlike pitchers, refrigerator filters, and other point-of-use systems, a whole house water filter system treats all of the tap water entering your home. This is especially helpful if you live in an area that has a poor water supply. The system will remove chemicals and impurities, making the water safe to drink and use for cleaning. You’ll also enjoy softer skin and hair thanks to the removal of harmful mineral deposits.

How to Install a Whole-House Water Purifier

Unlike tap filters or water jugs, whole house filters can be installed in the plumbing line that supplies all faucets and fixtures throughout your home. This is a relatively easy project for someone who has some experience with plumbing and is handy around the house. It is best to hire a professional plumber if you are unsure about the job.

First, you must determine the type of contaminants that are present in your home’s water supply. Different types of filters target specific contaminants. For example, city water typically contains chlorine and chloramine while well water usually has high levels of sediment or hardness minerals. Knowing what you want to filter will help you to choose the right system for your home.

Next, you’ll need to turn off the water supply. After shutting off the water, you’ll need to drain the pipes by opening all faucets and fixtures. This will release pressure and allow you to complete the work safely.

Once the pipe is drained, you can begin the installation process. First, you’ll need to locate the location of your prefilter. Ideally, it should be located in a horizontal run after the main water shut-off valve. If this area cannot be found, an Ising’s Culligan technician can “tee off” a section of vertical pipe to create a new area for the filter.
