🧾 Whole House Water Filter for Well Water Buyer’s Guide

Selecting the right whole house filtration system for your needs is a big job. Having the appropriate knowledge to make your choice is essential.

We’ve put together the following buyer’s guide to share everything there is to know about well water filter systems and maintaining your own water quality at home.

🏠 What Is a Whole House Well Water Filtration System?

A whole house well water filtration system is a system designed to remove harmful contaminants that are commonly found in well water.

As the name suggests, whole house water filtration systems filter the water in your entire home. They’re installed at your waterline’s point of entry, upstream of your water heater.

Some whole house filters for well water have multiple filtration stages, while others use a dedicated treatment process, like air injection.

How a Whole House Water Filtration System for Well Water Works

Most whole house well water filters combine two or three processes:

  • A sediment filter – which removes large particles and protects the media in the main treatment stage.
  • A main treatment stage – such as KDF, activated alumina, and carbon filters, a second sediment filter, or pre-oxidation and greensand or birm media.
  • A post filter (optional) – such as a UV filter, which removes microbiological contaminants that can’t be removed by most filters.

💸 How Much Does a Whole House Well Water Filter Cost?

The cost of a whole house well water filtration system varies widely. Expect to pay anywhere between $500 and $5,000 for this system, depending on the complexity of the filtration process, the number of filter stages, and the number of contaminants removes.

The annual cost of owning a whole house filtration system for well water is $50-$350, depending on how much, and what type of, maintenance is required.

🤔 Why Do I Need a Water Filter for Well Water?

Well water isn’t tested by the EPA ( Environmental Protection Agency) in the US. This means that you have no third-party proof of your water quality and that it is safe to drink – and chances are, it isn’t. 

If you drink water from a private well, your water may contain bacteria, parasites and other harmful microorganisms that could make you sick, as well as minerals that have leached into the water from its surroundings, including sulfur, iron, manganese and heavy metals.

The best whole house water filter system can trap these contaminants in your water, allowing you access to much cleaner, safer, fresher drinking water for your whole home. 

📌 How to Choose the Best Filtration System for Your Home

There are four important stages to choosing a whole house water filtration system for well water:

1) Understand Your Well Water Quality

The first step is to find out what your water contains. Use a DIY testing kit, or, for more accurate results, get your water tested by a certified laboratory. Note down which contaminants are most predominant in your water, and which you’d like to remove.

water testing with tap score

2) Identify the Appropriate System Type

Next, look at the types of systems on offer, and decide which system type is best suited for your contaminant removal needs.

Some systems may be out of your budget. Narrowing down your options will make it easier to choose a single filter that you can afford.

3) Determine the System Size

Once you know what system types are available, work out what sized system you need. To do this, you need to find out how much water you use every month. Look at your water bill to work out your average monthly water usage in gallons.

You can then look for systems that have high enough capacities to deliver the water you need every month. Some systems will have multiple size options, but most are designed for the average family of 3-4 people.

4) Find a System That Fits Your Needs

By now, you should have narrowed down your choice of whole house filtration systems significantly. Of your available options, choose the filter that best suits your budget, installation and maintenance needs, and space available.

🧪 Importance of Well Water Testing

If you don’t test your well water and treat it accordingly, you may end up drinking dangerously high levels of chemicals, heavy metals, or microbiological contaminants.

Testing your well water equips you with the knowledge you need to choose the best well water filtration system for your home. You can learn more about the importance of testing your well water here.

🧫 Most Common Contaminants Found in Well Water

The contaminants you’re most likely to come across in well water, and how they get into your water, are:

  • Arsenic – industrial and agricultural pollution, such as fertilizer run-off
  • Fluoride – naturally occurring in rocks and sediments
  • Volatile Organic Compounds (VOCs) – industrial pollution
  • Microbiological contaminants – poor well construction, leaking septic system
  • Radionuclides – natural deposits in rock formations, industrial processes like mining
  • Iron – seeps from the earth’s crust

How To Remove Iron From Well Water

Iron in well water can present itself in ferrous (soluble) and ferric (insoluble) form. Because ferrous iron is completely dissolved in water, you won’t be able to see it or smell it, while ferric iron may show up in water as reddish-brown cloudiness, and will stain your faucets and fixtures when it comes into contact with air.

The easiest way to remove iron from your well water is to find a filter that will do it for you. Oxidation systems oxidize ferrous iron into its ferric form, then filter it out using greensand or birm. 

The best whole house water filter systems can remove up to 30 PPM of iron from contaminated water.

How to Remove Coliform Bacteria from Well Water

Coliform bacteria is found in human and animal feces, and can cause diarrhea, abdominal pain, fever, nausea, and loss of appetite if consumed in drinking water. 

The best coliform bacteria removal solutions kill the bacteria, rather than filter it out.

UV purification involves treating water with ultraviolet rays, which damage the DNA of bacteria and inactivate them, preventing them from reproducing. 

You can learn more about the best ways to remove coliform bacteria here.

How to Filter Arsenic from Well Water

Arsenic is a semi-metal element that naturally occurs in the earth’s crust. It can also leach into groundwater sources through industrial pollution, and causes long-term health problems, including cancer and cardiovascular disease.

A number of filter systems can be used to remove arsenic from well water, including reverse osmosis, ion exchange, distillation, and activated alumina systems.

Click here to read up on the best methods of arsenic removal. 

✔️ Types of Well Water Filters & Contaminants They Remove

Oxidation Filters

Oxidation filters use chemical injection or an oxygen bubble to oxidize dissolved impurities, then filter them out using a media. These filters can remove:

  • Iron
  • Manganese
  • Hydrogen sulfide

Mechanical Sediment Filters

Mechanical sediment filters are cartridge filters that physically block large suspended solids that could damage your plumbing and delicate filtration stages. Targeted contaminants include:

  • Sand
  • Dirt
  • Sediment
  • Rust

Carbon Filters

Carbon filter cartridges use the process of adsorption to trap contaminants in their media. They can reduce or remove:

  • Chlorine
  • Fluoride
  • Pesticides
  • VOCs

KDF Filters

There is a range of KDF filters available, each offering its own unique performance. Depending on the KDF filter you opt for, it may be able to remove:

  • Chlorine
  • Iron
  • Copper
  • Zinc
  • Other water soluble heavy metals

Water Softeners

Water softeners are tank-based systems that use ion exchange to replace hardness minerals with salt. A water softener can remove:

  • Calcium
  • Magnesium
  • Low levels of iron

Reverse Osmosis Systems

Reverse osmosis systems provide thorough multi-stage filtration, including a semi-permeable membrane, and remove virtually everything from water, including:

  • Heavy metals
  • Chemicals
  • Bacteria
  • Fluoride
  • Arsenic
  • Nitrates and sulfates
  • Hardness minerals

UV Light

UV purification treats water with ultraviolet light. This process can remove:

  • Bacteria
  • Viruses
  • Protozoa
  • Cysts

There is no set list of contaminants that a whole house water filter must remove, which is why it’s important to get your water professionally tested to see which contaminants you most need a filter to target. 

🆚 Well Water Filters vs Water Softeners

Well filtration systems and water softeners are not the same. You can’t use a water softener to make your well water clean and safe to drink. 

A water softener produces soft water by removing hardness-causing minerals, like magnesium and calcium. These minerals cause scale in plumbing and appliances, affecting their quality and lifespans.

Unlike water filterswater softeners can’t remove any well water contaminants like viruses and bacteria, heavy metals, or manganese. Water softeners aren’t capable of killing harmful biological contaminants in tap water.

You may find that you need a water softener as well as a filtration system – but the two can’t be used interchangeably. 

Related: Best water softeners for well water (updated: 2022)

🆚 Whole House Well Water Filtration Systems vs Regular Filters

The biggest difference between whole house well water filtration systems and regular filters is installation location.

A whole house well water filter is installed at the earliest possible point in your home’s plumbing, has large tanks, and often backwashes or requires electricity. This kind of system filters the water supply in your entire home.

A regular water filter is used to treat your drinking water. Regular filters are small, compact, and affordable, but they don’t offer the same level of protection as a whole house well water filter.

💭 Key Considerations When Buying Whole House Filtration Systems

Well water filtration systems can cost upwards of $2,000, so it’s essential to be well informed before making a purchase. When deciding on the filtered water system for you, consider:

Contaminant Reduction Capability

The best whole house water filters for well water should be capable of removing the contaminants that are a problem in your own drinking water supply. You won’t know which well water filtration system best suits your needs until you know what your water contains.

Get your water tested to determine which contaminants you want to remove. You can then look for well water filtration systems that remove these contaminants, and compare them against one another.

System & Technology Type

The type of system can affect its size, performance, price, and maintenance requirements.

Most well water filtration systems are either tank or cartridge based. There are advantages and disadvantages of both. Tank based systems use a media that lasts longer than filter cartridges. However, they can be more expensive.

The type of filtration system you opt for should depend on the contaminants you want to remove, and to what extent.

Filter Capacity

Capacity refers to the volume of water a filter can treat before it becomes saturated with contaminants. Typically, this is expressed in gallons, but some manufacturers provide a suggested timeframe as well.

Backwashing systems, like air injection oxidation filters, have high capacities as the media doesn’t adsorb the contaminants and is backwashed daily. In these cases, the media bed will need to be replaced every 5-10 years once it becomes worn out. Cartridge-based filters are much smaller and tend to have shorter lifespans due to their restricted capacities.

Express Water Filter1 year or 100,000 gallons
Home Master HMF3SdgFeC1 year or 100,000 gallons

Water Pressure & Flow Rate

The water flow rate of a filter, measured in GPM, determines how quickly water can travel through the system.

SystemFlow Rate (GPM)
SpringWell WS12-20
SoftPro IronMaster6-12
US Water Systems Matrixx10-20
Pentair Iron & Manganese Filter Combo10-15
Aquasana Rhino7
Express Water Filter15
Home Master HMF3SdgFeC15

You need a filter that won’t cause a distinct drop in pressure, and has a high enough water flow rate to send water through your plumbing to meet your demands.

Here are the flow rates of common household appliances:

Appliance/ FixtureFlow Rate (GPM)
Toilet2-3
Shower1.5-4
Faucet2-3
Dishwasher2-4
Washing Machine3-5

Most well water filtration systems can only work with a minimum pressure of 40 PSI and a maximum pressure of 100 PSI. Make sure your home’s water pressure is within this range, and consider buying a booster pump if it isn’t.

You can measure your water pressure with a pressure gauge.

Sediment Pre-Filter Micron Rating

The micron rating of a sediment filter tells you what sized particles it can remove. The lower the micron rating, the smaller the particles the filter can remove.

A sediment filter with a 5-micron rating or higher is best. Higher-micron filters don’t clog as easily as filters with lower micron ratings.

Space Available & System Footprint

Some whole house filtration systems take up more space than others. Systems with multiple filters and add-ons, such as UV lights, will need plenty of room, especially if regular maintenance is required.

Measure your available space carefully before buying a unit. You’ll need to install your whole house water filter as close to your home’s point of entry as you can, so make sure you have the space you need before you buy.

Some of the best whole house water filters can be installed outside. Double-check if you’re exclusively looking for a system that’s safe for outside installation.

Installation

Some of the best whole house filtration systems can be DIY installed, but many manufacturers recommend professional installation by a plumber.

No matter what whole house water filter system for well water you opt for, installation will be relatively complex. You’ll need to cut through your main water line to install the system, and if you do it wrong, you’ll have to pay for the damage to be fixed.

The best way to determine the difficulty of installation is to read customer reviews. If the majority of customers have been able to install their system themselves, assume that you can, too.

Maintenance Requirements

Any system that has a filter will require this filter to be replaced, usually after 8 to 12 months of use. New filters come at a cost, and you’ll need to remember to change the filters every few months if you want to keep your system operating properly.

Tank-Based SystemsHigher upfront costHigher CapacityLimited maintenance involved
Cartridge-Based SystemsLower upfront costLower CapcityRequire frequent filter replacements

Well water systems that don’t use filters tend to perform their own automated maintenance, like system flushes, and require less frequent maintenance in the long run. If they contain media, this media will need replacing eventually; usually after 8 years.

If your whole house water filter comes with a UV filter lamp, the lamp will need changing once a year, and you will need to clean the sleeve to keep it working well.

System TypeAnnual Filter Replacement Cost
Cartridge-Based Systems$100 - $500+
Tank-Based Systems$25 - $100+
Well Water Systems$25 - $100+
UV Disinfection Systems$100 - $300
Reverse Osmosis Systems$100 - $500+
Chemical Injector Systems$50 - $500+

Certifications

If a filter has been either third-party tested to meet NSF Standards, or certified by the NSF itself, it’s a promising sign that the system does what it claims to do.

Common certifications for whole house water filters for well water are:

  • NSF/ANSI 61 – indicates that a system has been made from quality components
  • NSF/ANSI 42 – for chlorine or chloramine removal
  • NSF/ANSI 53 – for the reduction of health-harmful contaminants, like lead
  • NSF/ANSI 58 – for reverse osmosis filters that reduce total dissolved solids (TDS)

A number of whole house water filter manufacturers choose not to get an official NSF certification because of the costs involved. It’s usually cheaper for the manufacturer to have a third-party company test their whole house filtration system to check it meets NSF standards.

Warranty & Money-Back Offers

The greatest peace of mind that a manufacturer can offer is a lifetime warranty. When you know that a system has a lifetime warranty, you can rest assured that you’re protected throughout the system’s entire lifespan should anything go wrong.

Aside from warranties, some filter manufacturers also offer a shorter money-back guarantee, which entitles you to a full refund within so many weeks or months if you’re not impressed with the quality of the filter.

Ongoing Ownership Costs

The type of well water system you buy will determine your ongoing costs.

A cartridge system, such as a carbon filter system, will require regular filter replacements. This will increase your ongoing costs. Some filters last longer than others, so if you want to reduce your annual spend, look for a system with extra-capacity filters.

Whole house water filtration systems that use tank-based media are cheaper to operate in the long-run as they require fewer maintenance duties.

🛠 How to Install a Whole House Water Filter

Here, we’ve outlined the general process of installing a well water filtration system at your point of entry. Check your user manual to learn exactly how to install your filtration system.

  1. Check if you need to perform any tasks prior to installation, such as priming the media (this can take up to 24 hours).
  2. Shut off your water supply and open your faucets to drain the water from the pipes.
  3. Use a hacksaw or a pipe cutter to remove a piece of your main water line. Install bypass and shut-off valves upstream and downstream of the filter.
  4. Connect the whole house system, ensuring that the inlet and outlet ports are in the right positions. Use Teflon tape to seal the threaded ends.
  5. Gradually open your water supply and check for leaks. Tighten or add more tape if necessary
  6. Allow the filter to flush for several minutes – then it’s ready for use.

🔧 Whole House Well Water Filter Maintenance

Your maintenance duties are determined by the type of whole house water filter you buy. For instance, for tank-based systems containing media, you’ll need to replace the media every 6 years or so. For chemical injection systems, you’ll need to top up the chemicals every few weeks.

For standard cartridge-based systems, you’ll need to replace the filters as recommended by the manufacturer. Here’s a step-by-step on how to change a filter:

  1. Shut off the water supply and drain the water by opening your faucets.
  2. Use a filter wrench to open the filter housing and remove the old filter.
  3. Insert a new filter and lubricate or replace the O-rings if necessary.
  4. Turn on the water supply and check for leaks.
  5. Flush the cartridge if necessary.
