  • Its other filters also feature excellent water quality, resulting in the removal of 95 percent of contaminants
  • Reasonable price point compared to other models, like the 3M Aqua Pure


  • Unable to remove all iron from your water. However, as the Home Master HMF3SDGFEC whole house water filter eliminates more than 90 percent, this should not be a cause for concern.
  • It is difficult to install. In particular, it is essential to install plastic on the copper fitting to avoid leaks.

What Are Whole House Water Filters?

As the name suggests, whole house filters clean all the water that enters your home. The filter removes any contaminants in the water supply to ensure that water is purified before it reaches your pipes.

How Does a Water Conditioner or Filter Work?

Although every filter system is different, all whole house filters work in much the same way.

This type of filter system is attached to your main water line point of entry. That causes the water to pass through a filter or a set of filters before reaching appliances, faucets, and other water fixtures, including toilet water.

In some water systems, the water passes through just a single activated carbon filter. In others, it passes through any number of sediment pre-filters and copper-zinc or mineral post-filters, like with a reverse osmosis whole house water filter system, for example.

The excellent news with these types of whole house water filters is they waste much less water than reverse osmosis water systems, and they are more effective than a single point of use filter.

What Do the Best Water Filters Remove?

Every whole house water filter removes different contaminants. The best whole house water filters remove a wide variety of contaminants, whereas more budget options just remove certain substances. 

Filtration systems for city water may remove:
  • Chlorine
  • Sediment
  • Rust
  • Sand
  • Chloramines
Systems for well water also remove:
  • Metals, iron, manganese, lead, mercury, sulfur, copper
  • Hydrogen Sulfide
  • Herbicides and pesticides
  • Volatile organic compounds (VOCs)
  • Parasites, viruses, bacteria
  • Industrial solvents

Most of our top models above will filter out a wide range of water contaminants for both city and well water supply. Still, if you know that you just need to remove fluoride, you can see our best fluoride water filters page, or if you know you just need to remove iron in your well water, you can visit our best iron filters for well water page.

Why Use a Home Water Filter?

Protect Your Health

The main reason homeowners decide to purchase a whole house water filter is to keep their family members safe from illnesses. The contaminants in water can be damaging to your health in various ways. Removing them keeps you safe and gives you fresh, cleanly filtered water.

Extend the Lifespan of Your Appliances

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

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 universal system.

A Buyers’ Guide to Water Treatment Systems

There are significant differences between different water filter systems. When choosing the right one for you, it’s necessary to think about your priorities and requirements. For instance, it would be pointless to choose the best whole house water filter for well water if your home receives city water. Similarly, if you have a small house, you don’t need a whole house system featuring a high water flow.

What to Look For in Your Water Filtration System

When comparing water filters, there are several characteristics to consider. 

Understanding what each means and how it impacts the unit will help you figure out the best filtration system.

Flow Rate

The flow rate of a filtration system is specified in gallons per minute (GPM). The GPM needs to be high enough to meet the household’s water needs — for the average home; this will be about 15 GPM. When this rate is too low, water pressure to faucets and appliances drops.

Micron Rating

The micron rating tells you the extent of the filtration. For instance, portable water filters for hiking and camping have low micron ratings — down to as much as 0.1 microns. That is because they need to remove tiny particles that could be dangerous to your health.

In contrast, whole-house systems may only need a 5-micron filter. The exception is when 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 flow capacity. In that case, a solution could be to purchase a standard whole house water filter and install an additional filter where water needs to be extra clean — such as on the kitchen faucet. That will keep water flow high enough to meet your needs on appliances like the washing machine and shower.

Filtration Stages

As well as the micron rating, you can determine how well the system will filter water by looking at the number of stages. As the water passes through each stage, it becomes progressively cleaner. As a general rule, the more stages the filtration system has, the more purified the water will be.

For example, a 4 stage whole house water filter or 7 stage whole house water filter is handy. A three stage whole house water filter is decent but not quite as useful. A 2 stage filter is the most basic.

However, the number of stages alone only gives you part of the picture. The micron rating for each stage (5 microns or 1 micron) and what kinds of impurities each stage removes also matter.

Filter Type

That brings us to the next characteristic: filter type. There are two main types.

The first is heavy-duty filtration. These filters feature a ten-year filter life (or between 500,000 and 1,000,000 gallons), and maintenance is minimal. They typically have a carbon filter tank — as such, they are often called carbon tank models.

The second is standard whole-house filtration. These systems require whole house replacement filters at least every one or two years (or after up to 200,000 gallons), but the advantage is you can choose the filter you use to clean water of specific contaminants. Look for filters that have certification by the Water Quality Association.


Finally, there’s the cost of the water filtration system. In terms of upfront costs, standard whole house water filter systems are less expensive than heavy-duty filtration units. However, there are several additional expenses to consider. For instance, the filters of different models have different prices — and the more filters the system has, the higher the cost to make replacements.


If you have some experience with DIY projects, you may be able to install a simple water filtration system yourself. If you plan to call a plumber for the job, complexity is less of an issue, as the plumber should be able to install whatever system you choose.

Finding the Best Whole-House Water Filter for Your Needs

Now you know what qualities to look for in your filtration system, you need to assess your personal water needs. An excellent place to start is by testing your water. That will tell you what impurities are present in your water — and to what extent.

Next, 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, you may need the best whole house filtration system and a softening system. If your water contains bacteria, opt to include a UV attachment filter with your purchase.

Finally, you need to determine the right size of 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.

Installing a Whole House Water Filter System

If you have no experience with DIY projects, you’re better off relying on a plumber to install your water filtration system.

However, if you do have some basic knowledge, you may not find the task too difficult.

Below are the basic steps:

1. To start, turn off your main water supply. Do this by finding the shut-off valve and turning it until it’s completely closed.

2. Next, you need to drain as much water out of the system as possible. That involves turning on a faucet and waiting until the water runs dry.

3. Now, you’re ready to install the filtration system. Choose the location on your water source carefully, as you’ll need plenty of space to access the unit whenever it comes time to replace a filter. It’s also best to keep the system out of reach of any children in your household.

4. Once you have a spot, measure where you will position the shut-off valves and pressure gauges. Mark these places. With a bucket available for any water that remains in the pipes, use a pipe cutter to cut the water line. A reamer is excellent for removing any burrs.

5. The instruction manual for your whole house filter system may say that shut-off valves are optional, but they are handy for changing filters. Add them to both ends of the pipe. After this, you can mount the unit itself — you can mount it on plywood or mounting brackets.

6. Then, install the sediment pre filter, followed by the other filters (the correct order is typically available in the manual).
