Summary

We hope you’ve found this article useful and it has helped you get a better understanding of what a whole house water filter is and the important role it can play in providing your household with clean and safe drinking water.

Product Overview

Put simply – it is a water filtration system that filters all of the water that flows into your household. The way they work is by being installed at the Point of Entry (POE), normally before the water reaches any heating systems, faucets or machines. This is so that all water, whether hot or cold, gets filtered first.
This is different from the many other types of water filters that operate at the Point of Use (POU), such as connecting to a specific faucet or water pipe. Each has its own benefits and you can find reviews on the other types of filters on our website.

Why are they important?

There are a number of reasons why whole house water filters are a great choice for you and your family and these include:

Chlorinated water

Chlorine is one of the main ways that water companies treat water because it is very effective against bacteria and other harmful contaminants that can be found in a water supply.
However, just because it is good at removing harmful contaminants, doesn’t mean it’s good for you and studies have shown that it can affect your health, as well as your skin and hair. There is evidence that ingesting large amounts of chlorine can be dangerous for people’s health. It can also cause skin and hair to dry and look dull.

The environment

Choosing a whole house water filter will impact the environment less than other single point filters, and far less than buying water in plastic bottles.
However, this is because a whole house water filter doesn’t produce wastewater, unlike other water filter systems and so all water that you filter and subsequently enters the house gets used. Many of us purchase bottled water from the store and whilst these are often recyclable, they are still contributing to a growing carbon footprint and impact of the environment as they are being manufactured, bottled and transported.

Saving money

As mentioned above, this type of whole home water filter doesn’t produce wastewater and as a result, will save money compared to other systems. This is because you will not be paying the utility companies for water that you don’t use!

Furthermore, you will no longer need to buy bottled water from the store, as the drinking water in your home will have been filtered and as a result, be safe and healthy to drink.

How a whole house water filter works

You may be reading this whilst already having an understanding of what a water filter does and how it works in your household. Whilst there are some differences with a whole house water filter, in essence, it performs in the same way and aims to provide clean, safe filtered water.

The first thing to know is that a whole house water filter will connect to the main water line as it enters the property. This is so that all water is filtered prior to it being sent around the home or into a heater/boiler. It should be easy for you to find the main water line in your property but if unsure, you may need to ask for assistance.

For the vast majority of these systems, they operate in stages, with multiple filters or different types removing or reducing important harmful contaminants and unwanted minerals.

Stage 1

The first stage is normally a sediment pre-filter, whose main function is to remove larger particles from the water supply, such as sand, debris and sediment. This initial stage helps protect the subsequent filters, extending their lifespan and improving performance.

Stage 2

After this stage, whole house water filter systems go through an activated carbon filter which can be made from various materials, including coconut shell carbon, but they each have important characteristics. An activated carbon filter helps remove the vast majority of contaminants thanks to having a porous surface that the contaminants and harmful minerals attract to via adsorption.

These activated carbon filters (such as coconut shell carbon) will help remove chlorine, far smaller molecules of sediment and volatile organic compounds (VOCs). This is the point at which the taste and smell of your water will improve. Always check what carbon filter is used.

Stage 3

The next step is a special filter that helps further remove harmful contaminants including heavy metals, as well as bacteria. These filters are often called copper-zinc and mineral filters.

Stage 4

Now we get into the optional steps that some of the higher-end or more efficient whole house filtration systems will have. These include an ion-exchange phase which helps replace magnesium and calcium with sodium, making your water supply softer, particularly good for hard water areas. This process does add salt to the water but you can get salt-free water systems to counteract this.

Another optional stage but a very popular one is a water softener. Despite the filtration up until now, hard water can still be a problem and so a water softener is great at breaking down the small particles left. Likewise, an option UV filter can be included on the latest models to remove any remaining harmful bacteria, viruses or microorganisms. This will make your water supply truly clean and safe for your family to use as drinking water, washing with or cooking with.

Key Considerations

One of the most important steps in every purchase is learning about the key considerations and factors to be aware of. This is no different for the best whole house water filters on the market right now and we’ve put together some of the most important for you to think about.

Budget

First on our list of key considerations is perhaps the most obvious – budget! There are two ways to look at this and firstly, you need to think about what you can afford to spend and how much you wish to spend on replacement filters.

Once you have this in mind, you can see whether your budget is realistic for a whole house water system. If it is, you will have instantly narrowed down your potential options and speed up the buying process. After all, there is no point finding a filter that is twice your budget and unrealistic. If your budget doesn’t allow you to get what you need, then you need to think about whether a whole house system is what you need (perhaps it is just a single point filter) or look at whether you can increase your budget.

Flow Rate

This is a big consideration and an area you don’t want to underestimate. Fundamentally, all water going into your property will pass through this filter, so its flow rate which is calculated in gallons of water per minute will determine how your faucets, showers, appliances etc will perform.

To give you an example, most smaller households or apartments will cope with 10 gallons per minute (GPM) filter, but bigger households will find this frustrating and not suitable. There is plenty of research out there about the kind of flow rates required for each household size, the best for well water flow rates etc, so do your research first.

Types of filter used

As mentioned in the section above, whole house systems offer a range of filter setups, whether its multiple filters (such as a sediment pre-filter, activated carbon filter etc), added UV filter, water softener or a salt-free option. Each system will perform the basic filtration you’d expect, but then have a speciality or focus, unless you go for the higher end ones that deliver all-round performance.

As a result, we would advise you to understand what the water supply running to your house is like, whether it has a lot of harmful contaminants, high in heavy metals, bacteria or chlorine. That way you can then look at the most effective for your water. Perhaps you use well water and need a whole house filtration system that is best for well water.

Maintenance and filter longevity

A whole house water filtration system works hard because it filters everything that enters your house, unlike single-point systems that you can turn on and off or use sparingly. As a result, you need to research how long each filter or set of filters last. The vast majority will range anywhere from 100, 000 gallons up to 1,000, 000 gallons and within each system, filters will last different times depending on what they are.

Added to this subject is the consideration of maintenance. Fortunately, most of the latest systems require minimal maintenance but you don’t want to get caught out by buying a system that is complicated, time-consuming and costly to maintain.

Household usage

Do you know the water consumption in your household? It is unlikely you do unless you have specifically tested or checked. With the lower-priced systems you will burn through filters or suffer from slow flow rates and this is no good if your household usage is high. Likewise, you don’t necessarily need to buy the high-end models if you live in a household with lower consumption.

Installation

A final consideration is the difficulty and requirements for installation. The majority of the systems that made it onto our best whole house water filters are relatively easy to install and don’t require expert knowledge or a professional to help you. However, some of them may be more complicated than others, so it is a good idea to check reviews and manufacturers advice before buying. If you do need professional help, such as a plumber then this will add to the upfront cost of the unit and impact your budget.

Whole House Vs Reverse Osmosis

One of the common questions asked is whether to go for a reverse osmosis (RO) water system and why don’t whole house filters use one. To start with, reverse osmosis systems are one of the most effective systems for purifying water and will truly deliver clean safe pure water, but they are not efficient for most households.

A reverse osmosis (RO) system is slow at processing water and to perform at the required level for the average household, would simply not be possible, at least not without spending a fortune).

Secondly, you should remember that a lot of the water used in your household is for cleaning, washing, showering, laundry and more. That means you don’t need the cleanest, safest most pure water, unlike when using it for drinking water or cooking with.

Thirdly, the standard whole-house water systems don’t process wastewater, unlike reverse osmosis (RO) water systems, saving both money and protecting the environment.

It is our opinion that those people wanting to go for the safest, cleanest water should invest in an under sink reverse osmosis (RO) system so that only water at specific faucets go through this filtration system. It will be the most efficient and cost-effective way of doing things as you don’t really need pure whole house water supplies.

How to install whole house water filters

Each water filter has its own specific installation requirements and guidance, but there are some fundamental steps that all of them require, so to help you understand what will be required of you we have put them below:

Make sure you turn off the water system and drain it completely

Choose the correct location to place the water filter and mark it to ensure you measure it correctly. It is at this point that you should consider how easy it will be to access the location and replace filters when they are required.

Cut the pipe using the specific tools

It is here that you need to install the compression nut and fittings (brass/plastic) based on the specific instructions by the manufacturer of the system. Wherever you need to use tape, please make sure it is Teflon tape.

Install the whole house water filtration system with the in and out sections facing the correct way. Very important you don’t get this wrong at this stage!

Before you turn the water supply on, make sure you turn the water filters inlet valve off. Then turn on the water supply and check for leaks. If there aren’t any, then you’re good to turn the water filter inlet valve on. Repeat the process of checking for leaks.

Now that the installation process is complete (with the odd extra phase depending on the specific requirements of the manufacturer), you shouldn’t need to come back to the whole house filter except for changing over the filters inside. Every time you need to do this, make sure that you turn the inlet valve off and use the tools provided in the box. This is usually a specific wrench to fit the valves and nuts.
