I recently had a whole house filtration system installed, and the choices were a bit confusing — to say the least.

After doing a TON of research, reading the latest house water filter reviews, and talking to a handful of installation companies I put together this guide to help you choose the best whole house water filter for you.

Let’s face it… the water flowing out of our sinks isn’t the cleanest.

While most cities in the US have stringent cleaning standards, they can’t filter everything out. Water treatment facilities also tend to add high levels of chemicals like fluoride and chlorine.

If you want to get your drinking water clean and pure — just as nature intended — you need to do more filtering. Water filter pitchers are an inexpensive way to filter water quickly but need to be filled often and, obviously, don’t filter the water running over your toothbrush or the water you might use to cook with. Small water filters also tend to miss a lot of water contaminants. 

To quickly, efficiently, and more effectively filter the water into your home and improve your water quality, you need a whole house water filter.

If you want pure, clean water in your home and have been considering a whole house water filter, read on for a closer look at the best whole house filters, plus an in-depth look at how to sort through the many water filtration systems available.

The Best Whole House Water Filter for You

The best whole house water filter for your home really comes down to your needs and budget. With so many different types of filters available, you must consider what you need before you even begin to look at filters.

Do you want a filter that will get rid of the high chlorine content in your water?

Or do you need a filter that will eliminate the strong sulfur taste in your well water?

Once you know what you need… it’s time to think about budget and installation.

Do you have space for a whole house water filter?

How to Install a Whole House Water Filter

Once you’ve picked the filter that’s right for you, it’s time to get it installed!

Like we mentioned above, if you have some experience with DIY projects around your home and are comfortable working with water lines, you can probably install a whole house water filtration system.

But if not, you’ll be much better off calling a plumber. If you break or damage a water line, you may end up having to call a plumber anyway and pay far more than you might have by simply having a plumber do the work in the first place.

Now that you know what you’re in for… here are the basic steps to install a water filter.

First, you’ll need to find your main water line and shut off the water coming into your home. You must shut off the main water line before working on any pipes in your home.

Next, turn on a few faucets around your house and drain as much water out of the water supply as you can.

Once your pipes are ready, decide where you want to install the filter. Be sure to check the manufacturer’s instructions and check the components involved. You’ll want to make sure you have plenty of space so everything fits.

After you’ve found your spot, begin marking where each component will go and where cuts will need to be made in the water lines. Have a few buckets available to catch any water that may still be in your pipes.

Once everything is clearly marked, it’s to make your cuts. Cut the section of pipe where the filter will be installed with a pipe cutter.

Next, begin by installing the sediment filter along with the main filter and other filtering components. Be sure to refer to the manufacturer’s instructions for a detailed look at the necessary steps.

It’s also a good idea to install shut off valves before and after the filter. These can be very handy when changing filters or performing any maintenance on the system.

Once everything is in place, inspect all connections carefully and, again, check the manufacturer’s instructions and guidelines to make sure everything is installed properly and that all connections are secure with your new water filter system.

With everything in place and double checked, turn your water supply back on inspect everything for leaks.

If you don’t see any leaks, you’re water filter is now ready to go!

You should now have fresh, clean water at every source in your home.

Finding the Right Filter System for Your Home

Picking the best whole house water filter for your home can be tough… if you don’t know where to start.

Remember to begin with your needs and budget in mind. With so many different models available, you’re sure to find the best whole house filter that’s just right for your home.

What is a Whole House Water Filter?

Like the name says, a whole house water filter is designed to filter all of the water used in a home.

Unlike the filters found in some refrigerators or under some sinks — which only filter water at one source — whole house filters ensure that every drop of water used in your home has been cleaned of contaminants. This means you can take a shower free of chemicals like chlorine and have great, freshwater at every tap in your home.

How Water Filters Work

As you’ll see, some house water filter systems function differently than others. But all whole house filters perform the same (or very similar) function: remove water contaminants from drinking water as it enters your home.

To make this happen, a whole house water filter attaches directly to the main water supply line as it enters your home. This ensures that the water flowing to each of your fixtures is clean and ready to use.

Some filters pass all incoming water through several different filters, while others may only use one. Either way, you’ll get clean, ready to use water at every source throughout your home. All of the filters we’ve looked at use a fairly simple house filtration system that requires little to no maintenance — besides an occasional filter change for some.

Get Rid of Chemicals and Water Contaminants

Even though the water in your home may have come from a water filtration plant, it still may not be as clean as you’d think. Many filtration plants miss a lot of sediment in water and more is often picked up along the way. Rust particles are also common in many home water sources.

Water filtration plants also add chemicals to drinking water. Chlorine, fluoride, and other chemicals are often pumped into water as it’s treated.

Whole House Water filters can also help remove many contaminants from your drinking water, like:

  • Chlorine
  • Sediment
  • Rust
  • Sand
  • Chloramines
  • Herbicides and pesticides
  • VOCs

If your home gets water from a well, it can still be loaded with plenty of unpleasant stuff. You may not have chemicals added to your water, but well water is often full of heavy metals which can make water stink, taste funny, and stain your fixtures.

Water filters for well water can help get rid of:

  • Heavy metals including: iron, manganese, lead, mercury, sulfur, copper
  • Herbicides and pesticides
  • Parasites, viruses, bacteria and other harmful substances found in well water

Why Your House Needs a Home Water Filter

The great thing about a whole house water filter is the simplicity of the system.

While you may pay a bit more upfront, a whole house filter means that you don’t need to worry about where you’re getting your water from.

Want clean filtered water to fill your coffee pot?

Just use the kitchen sink rather than worrying about pulling a filtered pitcher out of the fridge.

A whole house water filter also ensures that your family isn’t regularly bathing or brushing their teeth with water that’s loaded with chemicals like chlorine, or contaminants like pesticides that are often found in water. Some filters even remove fluoride — a chemical that many are growing increasingly wary of.

Whole house water filtration systems are a great way to improve the health of your family by removing harmful substances from the water you use every day. Cleaner water can also help extend the life of your appliances and keep your clothes and dishes cleaner.

What to Look For When Shopping for a Water Filtration System

Whole home water filters come in many shapes and sizes. While shopping for the best filtration system for your needs, it’s really important to think about what your needs and priorities are.

A home that relies on well water will have very different filtering requirements than a home in a city, receiving regular tap water. 

The size and number of bathrooms in your home are also another major whole house water filter consideration. Bigger homes will need a bigger filter or a filter with a better flow rate.ff

There are a few major factors to consider when shopping for a filter. Make sure you understand each and how they’ll affect the water quality in your home.

Filter Type

When shopping for a water filter, you’ll notice that there are really just two types of filters.

The first type of filter available are large, heavy duty filters that are designed to last for a long time. These filters typically have a lifespan of about 1,000,000 gallons of water — or 5 to 10 years of use. These filters usually also feature a carbon block filter, designed to catch most major contaminants.

The other type of filters are smaller filters with one, or several, removable canister style filters that need to be changed more often. The filters in these models often need to be changed every 6 months to 2 years. This second type of filter is often much more affordable than the heavy duty style models, but do not filter out quite as much.

Filtration Stages

Most home water filters have at least two stages: a sediment filter and a primary filter. Some filters have multiple stages though, with various filters designed to catch different types of contaminants.

Water filters can even include UV filtration designed to kill bacteria and microorganisms, salt conditioning filters, and other special filters designed to get your water just the way you want it.

Be sure to consider what you want to remove and the necessary filter stages needed when shopping.

Flow Rate

No one likes low water pressure. 

So, be careful when shopping for a filter to look at the flow rate. The flow rate is usually calculated in gallons per minute or GPM. 

Filters with flow rates close to 15 gallons per minute will ensure that all of your fixtures have adequate water pressure.

Micron Rating & Filtering Capabilities

Another factor to consider is how much and what contaminants can be filtered by the water filter you’re interested in.

Many water filters have a micron rating which indicates how small of particles can filtered from water. Most whole home filters have micron ratings from around 1 to 5 — which is more than adequate for most homes.

The other filtering factor to be aware of is what type of contaminants and chemicals can actually be removed from water by the filter. If you want water free of chlorine and similar chemicals, be sure to check the filters you’re researching.


Installing a whole house water filter is a bit more involved than other types of filters designed to be used in a fridge or on a sink. If you’re an experienced DIYer and are not afraid to work with water pipes, you can probably handle installing a filter in your home.

But, if you’re not, installing a home water filter is usually a very simple job for a plumber to perform.


Price is obviously a major concern for anyone shopping for a home water filter. Thankfully there are a variety of models designed to fit many budgets and needs.

The heavier duty models do cost a bit more, but last much longer and filter more contaminants, so be sure to look at your budget and decide what’s right for you.
