Main Criteria to Look For in a Whole House Water Filter System

Main Criteria To Look For In A Whole House Water Filter

These are the five criteria we used to evaluate each whole home water filtration system, and they’re the main things that will determine if a system is right for your home.

Contaminants Removed

The water filter type a whole house system uses is going to determine the contaminants it removes, and these are the most common filters used in whole house water filter systems:

Filter TypeContaminants Removed
Carbon block filterOrganic chemicals, foul tastes and odors
KDF filterHeavy metals
Sediment filterSilt, suspended particles, rust
Air injection oxidizing (AIO) filter Iron, manganese, hydrogen sulfide

The best whole-house water filter system is one that removes the contaminants particular to your water, and you may get a water testing kit to identify which pollutants are most prevalent in your supply.

If your water contains germs or viruses, get a UV filter attachment with your water filter purchase.

Filter Lifespan & Capacity

Another thing to look at is how long it takes before you need to replace filters in water systems.

This is known as the water filter life or filter longevity. This can be anywhere from 6 months for pre-and post-filters, to years for the main one.

Similarly, capacity refers to the number of gallons a filter can process over its lifespan. Ease of filter replacement and cost are other things to consider as well.

Flow Rate

If you’ve ever tried to take a shower with a very poor flow, you know how frustrating it can be to have to wait on your water. 

The water supply, or the water pressure, that comes out of house water filter systems is one of the biggest things that affects customer satisfaction with a particular system.


The National Sanitation Foundation (NSF) and the Water Quality Association (WQA) are two independent entities that certify water filters for water purification and other products for meeting standards like the reduction of specific contaminants or using parts of a certain quality. 

Certification shows that brands put their money where their mouth is when it comes to claims about their products. See our guide to water treatment certifications here.


When looking at the whole house water filter systems, you have to take three factors into consideration to make sure it is cost-effective:

  1. The upfront cost of the water filter
  2. The installation costs of water systems
  3. The costs down the line from replacement filters and other maintenance
  4. Potential water waste

When shopping for a whole-house filtration system, keep in mind that it must be cost-effective and include the installation expenses as well as expected water filter replacements. These are the costs that most people overlook when purchasing.

Whole House Water Filter Buyer’s Guide

In our guide below you can learn everything you need to know about whole-home filters to make the best decision based on your home water needs.

What is a Whole House Water Filter?

A whole house water filter is a filter that treats all the incoming water that enters your home through its main water line.

This means that all the water in your home including sinks, showers, kitchen appliances, bathtubs, and any other water outlet will produce filtered water.

Whole house water filters are considered point of entry water filters because they filter water at your home’s main entry line.

There are a number of different types of whole house water filters which focus on filtering different contaminants based on the type of filter media they contain.

How Does a Whole House Water Filter Work?

A whole house water filter system attaches to your main water line’s point of entry.

When the water from your city or well supply runs into your incoming home water line the water passes through a filter or a set of filters before reaching appliances, faucets, and other water-using fixtures throughout your home.

This ensures that all the incoming water is filtered using the media in your whole home filtration system.

For a more detailed explanation check out our how do whole house water filters work page.

What Do the Best Home Water Filters Remove?

There are many different types of whole house water filters and they each remove different contaminants depending on what filter media they contain. The best systems will remove a wide variety of the most common water contaminants.

The main contaminants found in city water supplies:

  • Chlorine
  • Sediment
  • Rust
  • Sand
  • Chloramines

The main contaminants found in well water:

  • Iron
  • Manganese
  • Hydrogen Sulfide- produces the notorious rotten egg smell

Other potential contaminants in both (but more likely found in well water):

  • Herbicides and pesticides
  • Volatile organic compounds (VOCs)
  • Parasites, viruses, bacteria
  • Industrial solvents

In order to find out what contaminants are in your water specifically, you should educate yourself on water testing and purchase a water testing kit that will break down the types and amounts of each contaminant.

That way you can target your whole-house filter purchase to the one that will best meet your needs.

Most of our top models above will filter out a wide range of water contaminants for both city and well water. 

Why Use a Whole Home Water Filter?

Whole House water filter

There are several reasons to invest in a whole house water filtration system, from health benefits to improving the lifespan of your appliances.

Protect Your Health

The main reason homeowners decide to purchase whole house water filters is to keep their family members safe from illnesses associated with different contaminants like lead, pesticides, industrial run-off, bacteria, and more.

It’s not uncommon to find reports of excessive amounts of harmful chemicals in a city’s water supply.

Extend the Lifespan of Your Appliances

Cleaner water is also essential for your appliances. If the system has a filter that removes sediment, less sediment means less damage to the parts of your washing machine, water heater, dishwasher, etc.

Maintain the Color of Your Clothing

Do you ever notice that your clothes come out of the washing machine looking less clean than they started? 

White garments are particularly susceptible to stains due to dirty water.

Receive Better Results

You could fit a filter just on your kitchen faucet, but this would only provide you with clean drinking water – you’ll still be showering and washing dishes with contaminated water.

Adding individual filters to all your appliances and faucets could be an alternative, but this would be more expensive than installing one whole house filtration system.

More Sustainable & Eco-Friendly

By installing a whole home water filter instead of using bottled water you are also helping the environment since the use of plastic plays a role in harming our oceans and ecosystems. Not to mention it’s also a hassle to constantly purchase and store bottled water containers.

What to Look Out For When Choosing Your Home Filter System

There are significant differences between whole-house water filters, and when choosing the right one for you it’s necessary to think about your water quality issues and home specifications.

1. Make Sure the Specifics Match Your Home Water Needs

If you conducted a water test to determine which contaminants are in your water supply you will first need to find a home filter cartridge that removes the contaminants your water contains. Then you will need to make sure that the filter size, capacity, maintenance needs, and price fit your household.

See our cost breakdown guide here.

Depending on your home setup you may also need to look at factors like the dimensions of the system, the ease of installation and filter replacement, and the size of the inlet piping.

Make sure the specs match your home size and water issue and find the best price that fits those needs.

2. Figure Out The Right Type or Combination of Filters Needed

Think about what kind of whole house water filter would suit your needs. For instance, if your water source is well water that contains high quantities of iron, you’ll need to choose a filter system that removes iron.

If you have hard water as well as contaminants, you may need the best whole-house water filter and softener combo in one unit like Aquasana’s Rhino.

If your water contains bacteria or viruses, opt to include a UV filter attachment with your purchase.

The goal is to match the correct types of filters to your water contaminant needs.

3. Size The Filter Correctly

You need to determine the right size for the filtration system.

Large systems tend to offer a greater water flow, which is always beneficial for large houses. However, small homes and condos rarely require the same high flow – and it’s usually challenging to find space to fit a larger filtration system so it’s best to find a unit that fits those requirements.

4. Look at What Micron Rating is Ideal for Your Water

One additional consideration that may change how you want to set up your home’s filtration is the micron rating.

The micron rating tells you what size particles are filtered out of the water.

For instance, a portable water filter for hiking and camping has low micron ratings – down to as small as 0.1 microns. That’s because they need to remove tiny particles that could be dangerous to your health like microbial cysts.

In contrast, whole-house systems may only need a 5-micron filter. The exception is when the particles in your water are tiny, in which case you may need as low as 1 micron instead of 5 microns.

However, if you choose anything lower than this, your water flow pressure will drop considerably.

Suppose you require a tiny micron rating due to the incoming water’s low quality, but you’d rather not sacrifice your flow capacity.

In that case, a solution could be to purchase a standard whole house water filter and install an additional point-of-use filter where water needs to be extra clean – such as the kitchen sink.

That will keep the flow high enough to meet your needs on appliances like the washing machine and shower while still providing the cleanest drinking water at your kitchen tap.

Whole House Water Filter Installation & Maintenance


You may be asking yourself if installing and maintaining a whole house water filter is going to be a pain in the butt.

Basically, if you have some amount of plumbing or handyman experience working on your house then you should totally be able to install a new home filtering system without any issues. Most of the time the manufacturers include detailed instruction guides in the purchased kit and it’s not too complicated to set up.

On the other hand, if you have very little experience with handyman tasks then we definitely advise you to call a plumber to install your system. You don’t want to screw up your water line if you have no idea what you’re doing.

We go into detail on our whole home filter installation guide here.

In terms of maintenance with whole home filters, they really don’t take much time or effort to maintain besides a few routine tasks. Below are the basic steps to maintaining a home filter system:

  1. Install the filter correctly
  2. Implement a regular cleaning routine every few months (check for leaks and other issues)
  3. Change the filter cartridges on time (most have to be changed every 6-12 months)

Whole House Filters vs Reverse Osmosis Systems

While most whole house filters efficiently provide filtered water to your whole home, reverse osmosis filters are very inefficient and generate a lot of wastewater when used to filter a whole home.

Instead, reverse osmosis systems are most often used at individual faucets or fixtures for clean drinking water.

The reason reverse osmosis systems are popular is because of their effectiveness. They remove the most amount of contaminants from water including healthy metals, bacteria, chemicals, and most of the impurities whole house systems remove but the downside is they create a lot of waste and are very inefficient.

A good option to consider for the most complete water treatment solution in a home with very poor water quality is using a whole house filter on the point of entry and a reverse osmosis filter under your sink for drinking water. 

Just make sure to pick a reverse osmosis system that adds back in healthy minerals if you want that benefit.

Whole House Filters vs Water Softener Systems

Water softeners are point-of-entry systems that remove total dissolved solids (TDS) from the water like calcium and magnesium, which prevents scale buildup.

Most regular filters (including whole home) don’t remove TDS or minerals like calcium and magnesium, while most softener systems don’t remove heavy metals, chlorine, and other contaminants that whole home filters do.

Many people install both a water softener and a whole-home filter in one unit to take care of both contaminants and hard water minerals if their water quality is poor and some people decide to purchase one or the other or even both individual units.

Whole House Filter Additional FAQs


When other homeowners are looking for the best whole house water filter, these are the main questions that they’ve been asking.

Q: Do I Really Need A Whole House Filter? When Are They Not Needed?

A: If you get your water from a well, then you definitely need a whole house filtration system. While your city’s municipal water supplies should meet set standards for health and purity, you may want to remove some particles like fluoride or chlorine that remain, even though they’re at safe levels.

If you get your water tested and you find that there are no contaminants over recommended levels, then you may not need a whole house filter.

Likewise, if you’re only interested in increasing the quality of your drinking and cooking water, you can use a point-of-use filter on your kitchen faucet.

See our guide on determining if you need a whole house water filter for more information.

Q: Are Whole House Filters Worth It?

A: Yes, we believe they are. What’s the price tag for peace of mind? What’s the value of your family’s health? More tangibly, you’ll see real dollar savings since your appliances will have extended lifespans.

If you’re someone who thinks they want to create a DIY whole-house water filter to save a few dollars then make sure you are ready to deal with the hassles that come with that process.

Q: Can I Drink The Water Filtered By The Whole House Filter?
