22 Top Picks: Best Whole House Water Filter (Why You Need One Today)

If you don’t already have a whole house water filtration system, you should really get on it. With so many chemicals and foreign particles contaminating our water, having clean and safe drinking water has become a challenge. You can buy bottled drinking water to get clean drinking water but that can get really expensive in the long run.

Thankfully, there are water filters and water filtration systems that you can buy and install in your home to turn your tap water into clean, safe, pure and potable water.

Aside from drinking, water is used for a lot of other things, too, and that includes cleaning the house, cooking, watering the plants, taking a bath and brushing your teeth, among others. For these tasks, you’ll also need clean and safe water.

There are lots of water filters available in the market. Some are meant to filter water from the kitchen sink to turn it into drinking water, others are made to filter water from the shower to make sure it’s clean enough for cleaning your body and there are those that are designed to filter tap water and convert it into alkaline water.

While all those are sure to be useful, installing a water filter on every water source around the house can be expensive. If you want to make sure that you get clean and safe water all around the house all the time, why not get a whole house water filter? It’s like having all kinds of water filters for different water sources around the house in one.

A good whole house water filtration system will remove chemicals and contaminants in your water as it enters the plumbing system so that what you get from the shower, sink, or faucet is clean and safe for use and consumption.

Here are some other things to consider before grabbing one of these
products for your home...

Whole House Water Filters 
(Other Considerations)

While water that comes from the tap may already be treated, and can be considered clean, the fact is, many chemicals have been put into it – primarily chlorine – and the acidity or alkalinity of the water may not be the best for our own bodies. This is the reason why it is important to consider the use of a whole house water filter.

Before judging whether or not your home or neighborhood is likely to require a whole house filtration system, complete the following steps:

  • Do your homework. Find out from the local government offices how clean the water really is. This is particularly important if you’re near an industrial area, or if you know that the water source (a reservoir, for example) is near a manufacturing district. The same applies if you know that the local area has water infrastructure that hasn’t had a heavy upgrade in the recent past.
  • Gather even more info. Talk to neighbors to find out if people in the area have issues with the water, such as a strange taste, or if some of their family members routinely have upset stomachs. If you're new to the place, this may come of as a bit nosy so get friendly first, if at all possible.
  • Consider the whole 9 yards. Nothing is stopping you from having the water that comes out of the tap analyzed by a professional laboratory. This will give you solid, concrete data and a clear idea on what filtration systems you should use for your own home.

If your local government suggests that it’s a good idea to have your own filtration system, or if you think from anecdotal and factual evidence from neighbors that you need it, then it’s time to get one, if only for the health security and peace of mind that having a whole house filtration system can give you.

As a rule of thumb, you should consider filtration if you live in an area where water filtration on the community level is problematic because of water plumbing issues or source and main filtration concerns.


A true whole house water filtration system actually has to address many different issues:

1) Pre-filtering – Your first filtration tank or water filter section should be able to remove dirt and sediment, within 10 microns, if possible. In addition, it should be able to remove at least 80% of the chlorine that has been put into the water. This will do for your basic water filtration.

2) Filtration for waterworks maintenance – Depending on the water chemistry, you will probably have to treat the water with a second-stage filter that will remove most of the hard minerals in the water. This will ensure that your plumbing and fixtures will last longer, with less sediments depositing over time. It is also effective for your laundry, as it will prevent discoloration and will allow your detergent to be more chemically active with the water.

It should be noted that this type of filtration “softens” water, and some people may have skin issues with it. It’s also not a good idea to use softened water for plants or gardens.

3) Filtration for drinking water – You should install a third stage for your water filtration, particularly for the water you will use for drinking. You should use a water filter that can effectively filter particles down to 0.5 microns, and it should a of a solid-block type, like carbon.

At the end of the day, you should really determine your system’s functionality depending on the water situation within your local area. Here is another article on the different types of water pollution and how water filters can help with each type.

A good whole house filtration system would have basic and hard mineral filtration connected to the whole house, such that your whole water system will be filtered in this manner. However, you should have a third filtering stage fitted for your kitchen, so that you will have potable water available in the kitchen – something that you won’t necessarily need for other areas of the house.

Special Whole House Water Filtration Needs?

best whole house water filter products

Most whole house water filters are based on solid-block, granulated, and ceramic filters, all of which ensure that particle contaminants are removed. These filters are usually paired with activated carbon components and deionization filters, to remove dangerous chemicals and a considerable number of harmful organisms in the water.

However, in some places, special filtration systems are needed.

Water softening – As mentioned before, this will help with maintaining plumbing, and at the same time minimizing laundry discoloration. It also allows soap and detergents to lather up more. Ion exchange filters are normally used for this effect, where calcium and magnesium are replaced with sodium.

Ozone – Ozone filtering is used to kill bacteria and other microorganisms by aerating the water with ozone.

Ultraviolet light Like ozone filtering, ultraviolet light is meant to kill microorganisms and bacteria. This is usually done by having a small section of the filtration piping replaced with a translucent material that will allow ultraviolet light to pass through.

How Much Water Will You Be Filtering With Your Whole House Water Filtration System?

Aside from the various filtration modules that you may need, you will also need to consider the volume that you will be using. For a house with a small group of people, it’s possible that you will only need a small tabletop or under-sink filtration system. However, for larger families, offices, or even small buildings, you definitely will need large-scale filters that may have to be installed in the basement or in an outlying shed. These circumstances will ultimately guide your decision-making process when investing in the best whole house water filtration unit for your custom situation.

Breaking The Bank For The Best Whole House Water Filter

One important factor in planning your whole house water filtration system is cost. If possible, it’s probably a good idea to install it in segments first, so it won’t be such a big strain on your budget. In such a case, you could start first with basic filtration, and then keep on adding special filters as you save up more money.

The total cost for a whole house filtration system is usually around a thousand dollars or so, with a lower limit of around $500 to $600 for smaller families and houses. Whole house water filtration may sound like overkill for many people, but it is actually a serious health and safety issue. It is definitely worth the cost and preparation.
