Best Whole House Water Filters 2023 – How to Choose a Good One

What is a whole house water filter?

A whole house water filter is any unit that purifies all incoming water in a household, removing most contaminants and pollutants. Because of its size and power, a whole house water filter must be installed by professionals. This type of system eliminates the need for additional filtration devices such as under sink filters or shower filters.

Whole house water filters allow you to make one simple connection between your home’s main supply line and your home’s interior plumbing. In this way, the filtered water reaches every tap inside your home. They do not depend on electricity and can work with low-pressure sources such as well supplies or rainwater harvesting systems.

Types of Filters:

There are two types of whole house water filters. Each type is designed to remove different types of contaminants from the water supply.

1. Whole House Sediment Filters

A sediment filter traps suspended particles in your incoming water supply, removing dirt, rust or other solids that may be present. The reduction of sediment leads to improvement in the overall clarity and color of your water supply. 

2. Whole House Carbon Filters

Carbon filters are also effective at trapping various solids in the water but they do not remove metals or sediments like a sediment filter does. These units contain activated carbon which is porous and has an extremely high surface area for contaminant absorption (similar to how a sponge absorbs liquid). As contaminants pass through this media, they stick to the carbon and are trapped in the filter. These units need to be replaced on a regular basis depending on use, typically between 6 months and 1 year.

Why you should use a whole house water filter:

Using one of the best whole house water filter will eliminate the need for and hassle and expense of additional under-sink or shower-head filters. You’ll save space in your home and keep all your drinking, cooking and washing water free from contaminants. However, it is important to make sure you install a unit made specifically for water filtration (which means they may not be suitable for marine applications).

What is an undersink water filter?

An undersink water filter attaches under most standard sinks and uses activated carbon technology to trap impurities that can affect the taste, odor and color of your drinking water. These filters typically connect directly to your tap using a small plastic tube and can provide up to 100 gallons of filtered water before they need to be replaced.

An undersink water filter is a great alternative to an under the counter filter or whole house water filter for those that don’t have the available room, or just want a simpler solution that can be easily moved from one sink to another.

Whole house water filters are not designed for marine filtration applications where saltwater and freshwater will mix, but could possibly clog the filter element inside the unit if these conditions were present over an extended period of time. For serious marine use, you should look into purchasing a boat water filter system which was specifically designed with these conditions in mind. Take a look at our detailed comparison chart below to find out how each unit stacks up against other so you can make an informed decision when you are ready to invest in one of the best whole house water filters.

Buying Guide For Whole House Filter Systems

As you’re well aware, having clean drinking water is an important part of living a healthy life – but unfortunately it can be difficult to find great tasting water at the tap. This is because many systems are not designed with your health in mind, instead they simply focus on cleaning up after problems have already occurred. Today we’ll be exploring some excellent whole house filters that will provide you with cleaner, healthier drinking water right out of your kitchen sink!

If you live in any one of these areas then this should be high on your list of priorities – not only for yourself but for your family as well! If you want to make sure that everyone has access to clean, pure water inside their homes then this is certainly the way to do it.

As a rule, you’ll want to average around one gallon of water per day depending on your size and activity levels. If this sounds like a lot then you’re probably in need of a whole house filter – this allows for much cleaner drinking water without having to worry about seepage from the pipes or dirt in what’s left behind after filtration.

These systems are able to bring safe drinking water from any source – be it lake, river or otherwise thanks thanks to their high performance filters that can help remove harmful contaminants from many different sources with ease!

How Does It Work? How does this system work?

Great question, and one that we’re all too happy to give you an answer for! You see there are a few different types of filters on the market – most commonly they use either carbon or KDF filtration systems. Carbon filter systems feature activated charcoal which is used to remove several contaminants from your water supply including dirt, pesticides, chlorine and more. They can even help soften your drinking water by releasing healthy minerals back into it!

KDF filters are designed to work with copper-zinc alloy catalysts that can reduce or eliminate bacteria growth in your home’s pipes. This also works as a great protection system for any other metal elements being used around the house so you won’t have to worry about corrosion either.

The benefits of this type of filtering system are numerous, not only do they provide you with more healthy water for drinking but they can help prolong the life of your pipes inside your home – keeping them safe and working at their best!

This is also a great choice if you’re looking to save some money on your monthly water bill. Even though systems like these cost more up front, they pay for themselves after just a few months thanks to reduced distribution costs that will be passed along to you. This effectively makes purchasing one of these true long term investments that will work hard for you every single day!

How To Choose A Whole House Water Filter What do I need?

We’ve covered what whole house filters can do in general terms here on our website before, but we’re going to go a bit more in depth here and discuss what these systems actually do. We’ll also look at some of the best options on the market for this type of system and even take a look at how you can choose the right one for your needs!

Depending on where you live, finding high quality water to drink may be difficult – especially if you’re not careful. This is because it’s possible that those who handle your water supply will use harmful chemicals to deal with situations such as algae or bacteria growths that can be potentially hazardous to those drinking them.

However, there are other issues that you may need to worry about as well – like trapped debris from sources out in nature for example. Thankfully whole house filter systems are designed to help remove all of these potentially harmful things so you’ll never have to worry about your family getting sick!

How Do I Choose? With so many options on the market, how do you choose just one?

There are a couple of different ways that you can go about choosing the right whole house water filter for your needs – here’s what we’d recommend doing first.

Start by taking a look at your home. Are there any special situations where it doesn’t make sense to install an external system like this one (i.e near pools or shallow outdoor areas) If you do live in such an area then it may be best to try and purchase something like an inline filter instead which will work much better with shallow spaces like this one.

Once you’ve ruled that out, it’s time to look at your water supply source! If you have a private well then there are probably very few if any contaminants in the water to begin with so you can actually get away without purchasing a whole house filter. The same applies if you live in an area where the government regularly monitors your local tap sources – chances are they will test for common things like bacteria and other harmful items which will mean that even smaller filters may be enough to provide clean drinking water.

If this isn’t the case however, don’t panic just yet! Instead, try looking into pre-filtering devices that help remove some of these specific contaminants before being pumped into your home through another system. This way you can keep the overall cost down when compared to a high end whole house filter while still reaping many of the same benefits such as cleaner water and better overall protection.


Fortunately, there are enough options on the market for this type of system that you should be able to find something that’s well suited to your needs – no matter what they may be! Just remember to take your time when selecting one and make sure that you’re buying something that will work best in your particular situation. That way you’ll always know that your family is protected from harmful elements like bacteria or chemical runoff in any tap water source – giving you peace of mind each time somebody takes a drink!

Here are some of the most frequently asked questions about whole house water filter systems.

Q: What are the most important factors to consider when choosing one?

A: The first thing that you absolutely need to do is determine what contaminants are in your water supply. Different systems will filter out different things so it’s important that you know exactly what they are before purchasing.

Once you’ve got that down, you’ll need to figure out the best way for the system to be installed – especially if it has special requirements or can easily be damaged with incorrect installation. You should also keep an eye on how much space it needs as well as its overall weight so you don’t damage your home by accident!

Finally, look at how much waste water is created by the system and whether or not this could affect any landscaping or other items around your home. If you’re not careful this can lead to some major problems down the line which is why it’s important for you to know beforehand!

Q: How do I make sure that it will fit?

A: That depends entirely on what type of system you end up buying. Some whole house filters are designed to work in conjunction with existing ones like those installed by pool owners, while others rely on pre-installed components.

You’ll also need to keep an eye out for any special requirements that might affect where you place the filter itself – especially if anything nearby could be damaged by regular waste water runoff or excess pressure. This is something that may seem unimportant at but could actually cause damage if ignored!

Q: What are the best ways to maintain my whole house water filter?

A: Most of these systems operate on simple pressure cycles before eventually shutting off completely – giving you plenty of time to check for any leaks or other problems. If you notice anything like this, make sure to turn it off and contact your local contractor immediately! Later on down the road you may also want to consider getting a professional cleaning done if possible as well. This will ensure that everything continues working properly for years at a time with minimal maintenance required beyond basic upkeep.

Q: Will it be expensive to install?

A: That depends entirely on how large your home is and where exactly you plan on installing the system itself. The good news is that many of these systems are designed to be installed by anyone who’s at least partially handy – including you! This means that the cost won’t likely exceed what you would pay for a professional installation. Ideally, however, you should look at having it professionally done to make sure that everything is positioned correctly without any issues!

Q: What type of system will be best for my needs?

A: That depends entirely on how much space your home has available as well as whether or not you’re planning on using the water in other areas besides just drinking water. For example, if you want cleaner bathing water then you’ll need one that can handle additional pressure and work with your existing plumbing – saving space where possible. If, on the other hand, you’re more interested in the quality of drinking water then you might want to look into something that can handle all of your needs and more!

Q: Are there any dangers to be aware of?

A: Yes, there are! These systems use fairly large amounts of pressure and chemicals to cleanse water effectively which means that improper installation can cause serious problems. You should never attempt to install one on your own unless you have some professionals who will be able to assist with it afterwards if need be. 

If your system uses chlorine at all then you should also take extra care not to mix it with other substances as this can create dangerous gas which can lead to some very serious health problems if inhaled.

Finally, keep an eye out for smaller contaminants – especially things like algae or bacteria that could affect the taste of water before even getting into the filter itself. If left alone these may cause the entire system to have to be replaced before it’s even been installed!

Q: What can I use my home water filter for?

A: That all depends entirely on your needs as well as what you’re going to be using that water for. For example, if you just want cleaner drinking water then a simple pitcher-style system would do the trick. On the other hand, if you’re looking for better bathing or cleaning solutions then a larger whole house system might actually fit your budget better in the long run – even though it may take more work and cost at first.  

Even something like an outdoor spa could benefit from this type of treatment because it relies on large amounts of pressure to make sure everything is properly filtered. This means that you can use it both indoors and outdoors without any problems whatsoever.

Q: What do I need to know about the chemicals?

A: When choosing a system you should always check to see if chemicals are needed at all. This is especially true if you’re looking for a more natural solution which works using nothing but pressure from your home or business’ existing pipes! If they are required, however, then make sure that the system itself is designed to handle them so that there aren’t any issues during cleaning cycles.

In addition, be careful of what type of water goes into the filters in the first place – especially after it’s been cleaned with other methods like boiling or distilling. Since these tend to leave substances behind that can eventually lead to clogging, you should always clean things with a simple vinegar or baking soda solution before putting it into the system itself.

Q: Can I make a DIY water filter?

A: Yes! In fact, there are even kits out there which will allow you to do so with relative ease. The issue is that they may not be able to handle all of your needs while still being cost effective enough for your budget .

For example, if you just need cleaner drinking water then something like this would likely work well for you. On the other hand, if you’re looking for better bathing and cleaning options then one of the larger systems would probably suit that purpose better – especially since it could remove more harmful chemicals from the water.

Q: What kind of system should I choose?

A: Again, that all depends on your needs and budget. If you’re looking for something small then a pitcher-style filter can cleanse small amounts of water quite effectively if it’s properly cleaned out regularly. On the other hand, there are also larger systems that work to treat an entire house’s worth of water at once – saving both time and money in the long run by not having to replace filters as often or worry about cleanups after using certain chemicals!
