What exactly is a whole house water filter?

As the name suggests, this is a filtration system that filters all of the water which enters your home. Systems like this are also called POE (point-of-entry) because they are installed at the very beginning of the plumbing system, before the heater. This allows them to efficiently filter every single drop of water that runs in your house – cold or warm.

So, the filtered water will run from every single faucet, every shower, and will be delivered to your dishwashing machine, your washing machine, your toilets, and every other appliance connected to the plumbing system in the house.

Features to look for when buying a whole house water filter

Because we all use different water sources and live in different areas, the quality of the water in our homes differs. This means that if one water filtering system works perfectly for someone in one city, it may not be efficient at all in another.

Since whole house water filtering systems are important for our health and are also usually quite expensive, it makes sense to consider the features you should look for when choosing the best whole house water filter for your home.

Here is what to consider when shopping for a whole house water filter:

Your overall water consumption

If you want to make the right choice and get a filtering system that will work adequately and filter all of the water in your home, you should first consider your whole household water consumption.

Choose a filtering system that will meet your consumption without the need to replace the filters every month.

Calculate how much the filters cost and how often you will need to replace them, given your current consumption to make the best and most financially reasonable choice.

By planning ahead, you will know how much the average cost of maintaining the whole house water filter system will cost you over time.

Try to balance the consumption of water and the longevity of the filter for the best results.

The water quality, and the contaminants in it

To ensure that you purchase the right type of whole house filtering system which will actually clean your water and ensure that it is safe to drink and use on a daily basis, you need to know what the contaminants in your water are.

The best way to find out is to test the water with a home test kit or ask a professional to perform the tests.

Even without a test, if you are using municipal water, you can be pretty certain that it is chlorinated. If your water source is from a well, there are risks of heavy metal, chemicals, and other contaminations too.

Even though chlorine is an excellent disinfectant and is essential for decontaminating the water, in high doses, it could be harmful to you. Plus, some people are allergic to chlorine.

The tell-tale signs that your water needs filtering include a cloudy appearance, a strange smell and taste, dust and other small particles floating in it, high levels of bacteria, and others.

You should choose a water filtering system that is capable of reducing or eliminating the specific contaminants your water is affected by.

Many of the whole house water filters on our list have sediment and chlorine filters. These are more suitable for those of you using municipal and chlorine-treated water.

Others will capture and trap sediments, as well as certain heavy metals like iron or lead. These are suitable for households using well water or water with high levels of these harmful heavy metals.

The size of the particles removed

Each filter has a certain capacity of removing contaminants and particles of a particular type and size.

After looking at your water test results, you should pick a filtering system which can remove the contaminants found in your water.

The high-quality filters will remove particles and pollutants as small as 0.35 microns. These are suitable for water which comes from a highly contaminated source.

If your water test results are not so alarming, you may want to opt for a less expensive filter that removes particles as small as 1 micron.

1 micron is equal to a thousandth of a millimeter.

The filtration stages

Just about all whole house water filters can remove the sediments and other primary contaminants from the water. These include sand, dust, rust, chemicals, and others. In fact, many inexpensive whole house water pre-filters can do this job pretty well too.

Most of the filtering systems on our list offer more than one stage of filtration. This means that the pre-filter will trap the larger particles, and the water will pass through the next filters for additional filtration for specific contaminants like iron, lead, manganese, bacteria, and various other impurities, as well as the foul smell and taste of the water.

Keep in mind that only the reverse osmosis filtering systems can guarantee that 100% of the impurities will be removed from your water. This though is an extremely expensive investment to make, so if you do not have serious problems with contaminations, you may want to opt for the two or three-stage filtering systems which can remove 95-97% of these contaminants instead.

The filter type

As mentioned earlier, the different types of filters can block different types of contaminants. It is essential to base your choice of a whole-house filtering system on the water tests and choose the filter types that will remove the pollutants plaguing your own water source.

There are filters for chlorine, pesticide, herbicides, and VOCs, as well as filters for heavy metals like lead or iron. The UV filters are a must if the water test results show high contamination of bacteria.

Filter NSF certification

The certification of a filter proves that it can remove the precise contaminants it is being advertised for.

There are several standards for filter certification by the NSF and ANSI, including:

NSF/ANSI 42 – filters which reduce odor, chlorine taste, and particulates only

NSF/ANSI 53 – filters which utilize carbon to eliminate certain heavy metals, herbicides, pesticides, giardia, and others

NSF/ANSI 401 – filters which are capable of capturing pharmaceuticals found in water, including chemicals, prescription drugs, pesticide, herbicides, and others

NSF/ANSI 58 – filters used by the reverse osmosis water filtering systems for removing radium, fluoride, nitrate, nitrite, perchlorate, heavy metals, and other dangerous contaminants

The longevity of the filter, and the replacement interval

As you can see from our product descriptions, each system, and each filter has a specific capacity. Some have capacities of 50,000 gallons, others for 100,000 gallons, and we have picked a system that has a humongous 1,000,000 gallon capacity too.

This capacity is the amount of water the system can filter before its cartridges or filters need to be replaced.

An average household of four people can expect to use a filtering system with a 100,000 gallon capacity for 1 year.

The same household can use a filter with a capacity of 1 million gallons for up to 10 years before the need for a replacement.

Some systems have quick-change systems, making the filter replacement very easy.

Others, like the Whirlpool whole house water filter, are actually filterless and flush themselves automatically, but they are not as advanced in removing some more specific contaminants from the water.

So, calculate your overall water consumption, and check out the capacities of the filtering systems, as well as the prices for the replacement filters before buying a whole house water filter. This will give you an idea of the ongoing maintenance costs you will need to prepare for.

The flow rate of the system

In order to prevent any drops in the water pressure throughout your home, you should opt for a water filtering system with a flow rate sufficient to supply every single faucet, toilet, shower, appliance, and other places in the home that require water with filtered water. You should choose a filtering system that will have no impact on the normal water flow, even if several faucets are opened simultaneously.

A system with a flow rate of 10-15 gallons per minute (GPM) should be sufficient for most average households.

The warranty

Since most whole house water filter systems are quite expensive and will have ongoing costs over time for filter replacements, you may want to check out the warranty terms of the different manufacturers before picking the best filtering system for your needs.

Obviously, the longer the warranty, the better.

Some of the systems on our list offer 30-day to 6-month money-back guarantees too, which is another excellent offer for peace of mind.

Additional features

There are some other features that are worth taking into consideration when shopping for a whole house water filter.

One is the ease of installation. This is important if you are looking for a system that you can install by yourself. Some of the water filter systems come with all the tools and kits needed for installation. Others are more complicated and may require a professional plumber.

The cost. Obviously, the cost is something that everyone pays attention to. But remember that a whole house water filter may be a one-time purchase, but the majority of these installations need ongoing maintenance and filter replacements, some of which can be pretty costly.

The types of filters for whole house water filter systems to choose from

While all of the whole house filtering systems work on the same principle and are attached at a point-of-entry to the main water line, prior to the heater and before entering the home, the different filters included in these systems have different functions.

Here are the basic types of filters to consider for your own whole house water filter system:

The pre-filter

The pre-filter is usually an inexpensive and straightforward filter, which, in most cases, can be washed and reused or will clean itself. The pre-filter captures the larger contaminants, like slit, rust, sand, dust, debris, and sediments.

Not only will this filter prevent these larger particles from entering your home plumbing system, but it will also keep them from passing from the next, more complex, and more expensive filters in the system.

A good pre-filter can seriously expand the longevity of the other filters in the system.

An activated carbon filter

This is among the most essential components of any whole house water filtering system, as it is capable of removing a wide variety of contaminants.

The activated carbon has a porous surface that attracts and absorbs the contaminants naturally.

Activated carbon filters can remove smaller sediment particles, VOCs, as well as any bad smells and tastes from the water.

In some cases, these filters are impregnated with silver in order to eliminate bacteria as well.

Copper zinc and mineral filter

This one is usually located after the activated carbon filter and can remove a large percentage of the remaining contaminants from the water. It can remove the residual chlorine, heavy metals, and microorganisms, including bacteria. It also helps descale the water.

A water softener or descaler

After the incoming water has passed through the filtering system, it may pass through an optional water descaler or softener. Many manufacturers use ion-exchange filters, which help soften the water through special sodium ion filled resin beads. Others use salt-free softeners instead.

A UV filter

This is another optional filter that you can consider adding to your whole house water filter system. The UV filter is capable of eliminating any remaining microorganisms, viruses and bacteria in the water after it has passed through the filtering system.

A UV filter is a must if your water has high bacteria contamination.

The post-filter

This is the final stage of the water filtering process. The post-filter will remove the smallest particles that have made their way through the primary filters. Usually, post-filters look like mesh. The size of the holes of this mesh is what matters. There are some post-filters which can stop particles as small as 0.35 microns from passing through, though the more common type of post-filters is capable of capturing particles as little as 1 micron.

Final words

We are hopeful that this comprehensive guide on buying whole house water filter systems has helped make a more informed decision about the one which will be the most appropriate one for your needs.

We recommend that you perform a water test, and measure the overall water consumption of water in your home first. These two steps will give you the basis for finding the most appropriate water filtering system which will efficiently remove the specific contaminants found in your water, and which will be as financially efficient as possible.

With a good quality whole house water filter system, you can rest assured that all of the people, animals, plants, and appliances in the home will be much safer and healthier.

You will also save tons of money from using separate filters for each faucet or appliance, buying bottled water, and paying for repairs and replacements of the devices which use water and get damaged by the sediment build-ups.

Good luck with your purchase, and enjoy your perfectly clean water from any faucet in the house, with one of these excellent whole house water filters!
