7 Best Whole House Water Filters for Well Water of 2020

best whole house water filter for well water

If you own a home with a well, it makes sense that you should use your well water for drinking.

Around 13 million homes in the US use a private well for drinking water. While there are certainly benefits to this, it’s important to remember that in the case of having your own well, your water quality is entirely your responsibility. 

It’s common for well water to contain bacteria like E. Coli, protozoa, and some viruses which could cause you to fall ill if you were to drink it. It also contains a high content of hard water minerals, such as calcium and magnesium, and iron which can cause a mineral buildup in your home’s water pipes and heating system. 

Fortunately, it is possible to eliminate your risk of consuming potentially harmful and nuisance microorganisms, and the solution is as simple as running your water through a well water filter system. 

This guide will teach you everything you need to know about well water filtering, and help you to find the best whole house water filter for well water.

Aquasana 500,000 Gallon Well Water Rhino

Aquasana 500,000 Gallon Well Water Rhino

The Aquasana Rhino is a well water filtration system that is designed for whole home use. With a unique dual tank design, the Aquasana Rhino increases the water contact time with the filter media, allowing for more thorough filtration


  • Type: Carbon Filter & salt free water softener combo
  • Capacity: 5 years or 500,000 gallons
  • 7 GPM flow rate
  • Dimensions: 57 x 10.5 x 15 inches
  • Optional UV filter
  • NSF certified
  • 90-day guarantee

You can use the Aquasana well water filter for the removal of hard water contaminants, calcium and magnesium, which cause scale build-up in your home’s pipes. The system uses a salt-free means of softening water, known as scale control media (SCM) technology. It naturally alters the structure of hard water minerals, crystalizing them and preventing them from being able to bind to surfaces. 

The filter also includes an optional UV purifier, which sterilizes bacteria, viruses and cysts by altering the DNA of these microorganisms, killing them and preventing them from being able to reproduce. 

Additionally, a sediment pre-filter traps rust, silt and sediment; a copper-zinc and mineral stone filter reduces heavy metals and prevents algae growth; an activated carbon filter reduces chemicals like herbicides and pesticides; and a post filter eliminates any remaining sediment. 

Because the Rhino system contains filters, you will need to factor in for the cost of filter changes in the future. The filters have a 5-year capacity, so you won’t need to change them frequently to ensure that the system is working well. It’s important, however, that you don’t forget about filter changes, as the system won’t do its job once the filters have reached the end of their lifespans. 


  • Doesn’t add chemicals or salt to water during filtration/softening
  • Uses multiple means of filtration to eliminate a broad range of contaminants
  • Both filters and softens water


  • Lower flow rate
  • You will need to purchase additional fittings for installation

Pelican Iron & Manganese Water Filter

Pelican Iron & Manganese Water Filter

The Pelican Iron & Manganese system is a whole house water filter for well water. It uses a 4 stage system to filter out sediment and oxidize iron, which changes it to rust, and is then eliminated from the system. Coming complete and ready to install, the system removes up to 10 PPM of iron – drinking water should have a maximum of 0.3 PPM of dissolved iron. 


  • Type: Activated Carbon & Backwash combo
  • Capacity: 5 years or 600,000 gallons
  • 10 GPM flow rate
  • Dimensions: 62 x 37 x 23.5 inches
  • Chlorination filter
  • WQA Gold Seal Certification
  • NSF/ANSI 61 & 42 certified
  • 5-year guarantee

Each stage of the Pelican well water filter has a different purpose: 

  1. The first stage, a 5-micron pre-filter, removes sediment from water; 
  2. The second, a chlorination system, disinfects the water; 
  3. The third, the iron removal filter, traps the iron and flushes it out with a backwash system; 
  4. The fourth, the carbon filter, reduces chlorine, chloramines, sediment, and any particles that may affect the taste and odor of your water. 

The Pelican well water filter essentially plays the role of a water treatment center, but on a much smaller scale. It processes water using the same means of filtration and disinfection, providing a guarantee that your water will be safe to drink and pleasant in taste after treatment. 

Chlorination is an essential part of the water treatment process, and can kill disease-causing pathogens, like bacteria and viruses. The chlorination system operates without electricity, and adds the exact amount of chlorine needed for the volume of liquid entering the injector. 

The Pelican well water filter’s GreenSand Plus iron removal system complies with NSF/ANSI 61, meaning that it meets standards enforced by state and federal laws. The carbon filter complies with NSF/ANSI 42 for to certify that it meets the minimum requirements for removal of aesthetic contaminants, like water taste and odor. 

It has a 5-year performance guarantee, so maintenance is much more manageable than for other whole home water filtration systems. 


  • Easy to set up and install
  • NSF Certified for Standards 61 and 42


  • Some customers have reported a loud noise from the chemical injector pump
  • One of the higher priced well water filtration solutions

SpringWell Whole House Well Water Filter System

SpringWell Whole House Well Water Filter System

This SpringWell system is considered the best filter for well water by hundreds of customers, thanks to its innovative technology and the manufacturer’s decades of experience in the industry. It isn’t only designed to effectively disinfect and filter water from a private well – it has features that make it environmentally friendly and economical as well. 


  • Type: Backwash filter
  • Capacity: 10 years or 1,000,000 gallons
  • 9 GPM flow rate
  • Dimensions: 13 x 54 inches
  • Optional UV filter
  • Control settings with phone App
  • 6-month guarantee

The SpringWell system filters water in 4 different stages. 

  1. First, water flows through an air pocket at the top of the system, which oxidizes the sulfur, iron and manganese. 
  2. In their new forms, it is now possible for these particles to be removed from water. The SpringWell features a bed of green sand fusion, which traps the particles and prevents them from passing any further. 
  3. In the third stage of filtration, the system’s automatic backwash sends these particles out of the drain, and replaces the pocket of air with a fresh one. 
  4. The clean, fresh water that remains is then sent into your home’s water pipes for immediate use. 

If your well water contains iron, manganese, sulfur, or a combination of the three, the SpringWell filter will transform it into something that tastes good, looks clean,and  doesn’t stain or smell. The system removes up to 7 PPM of iron, 8 PPM of hydrogen sulfide, and 1 PPM of manganese.

One of the biggest plus points of this whole house well water filter is that it requires virtually no maintenance. This is because, unlike the majority of whole home systems, the SpringWell backwash system doesn’t actually use any filters. You can simply set the system to run a backwash on a daily basis, which will wash the contaminants away from the filter media and add fresh air to the system, removing the potential sulfur smell. 

A feature that sets the SpringWell filter apart from similar systems is its Bluetooth app, which lets you adjust your system’s settings from your phone without having to visit your system in person. With the SpringWell app, you can view and change your valve settings, start a backwash cycle, and view current and historical water usage data. 


  • No maintenance needed after installation; no filters used
  • App allows you to view and amend settings from your phone


  • Roughly double the price of an average well water filter
  • May need to factor in additional costs for professional installation

  3. The third filter, made from a carbon block material, captures chemicals in water, like chlorine, pesticides, herbicides and other chemicals that affect taste and odor. 

You receive three initial filters with your purchase, but you’ll need to be prepared to buy some more after 6 months to a year of use. The system won’t work once the filters have outlived their recommended lifespan, so it’s important that you’re prepared to invest in a yearly or bi-yearly additional cost before you purchase.


  • Simple enough to install yourself
  • Offers high flow rate filtration


  • Filters need changing frequently
  • You may need additional fittings and connections for installation

Home Master 3 Stage Filtration System

Home Master 3 Stage Filteration System

The Home Master system offers three stages of filtration and is ideal for using to treat well water. With large filter housings that allow for a flow rate of up to 15 gallons per minute, you won’t need to wait around for this system to produce clean, fresh drinking water for your home. The system is designed to remove up to 95% of chemicals, sediment, and other contaminants that affect water appearance, taste and odor.

  2. The second filter is a radial flow filter and reduces up to 3 PPM of iron
  3. The third, an activated carbon filter, removes chemicals like pesticides and herbicides from water. 

The oversized filters don’t require as frequent maintenance as other systems, though of course, some well water filters don’t use filters at all. In the case of the Home Master, you’ll need to change your filter roughly every 8 months to 1 year, depending on your water quality and household usage. You can buy new filters from Home Master online, and replacing them is simple enough for everyone to do.

Being designed specifically for well water use, the manufacturer advises against using this system for chlorinated city water. They also recommend checking your installation area, conducting a water report, and having a free consultation with them before purchasing your system. These steps will help to ensure that you invest your money in the best filter for well water based on your needs. 


  • Many people have found the system easy enough to install themselves
  • Multiple filtration stages target different contaminants


  • Requires more maintenance than other systems
  • Doesn’t remove as much iron as other filters

iSpring  3-Stage Whole House Water Filtration System

iSpring 3-Stage Whole House Water Filtration System

The iSpring 3-stage system is a whole house filter including a sediment well water filter and two carbon filters. Removing up to 99% of chlorine from water, the system can be used for city water in addition to well water. It also removes 95% of sediment, including rust, as well as chemicals like pesticides and herbicides, VOCs, industrial solvents, and other contaminants.

SoftPro IronMaster Water Filtration System

SoftPro IronMaster Water Filtration System

The SoftPro IronMaster is an iron filter for well water that also removes sulfur and manganese using air injection technology. Designed as an efficient, economical way to remove iron and other contaminants from water, the SoftPro system doesn’t use dangerous chemicals or expensive pumps to get the job done. It simply creates an air bubble for oxidation, before sending water through filter media. 


  • Type: Backwash filter
  • 6 GPM flow rate
  • Dimensions: 10 x 54 inches
  • UV filter: No
  • 60-day guarantee

When incoming water passes into the IronMaster, the system adds oxygen by sending it through an air bubble at the top of the tank. When this happens, the iron, sulfur and manganese become oxidized. The water is then sent through a filter bed, which prevents the oxidized particles from being able to proceed any further. As soon as the oxygen in the air bubble is used up, the system runs a regeneration cycle, removing the iron from the media and introducing more oxygen into the tank. 

The SoftPro IronMaster removes an impressive 30 PPM of iron from well water, along with 7 PPM of manganese and 5 PPM of hydrogen sulfide. It does all of this without using additional oxidizers or disinfectants like chlorine, which some whole home well water filters use. 

You don’t need to carry out much maintenance on the SoftPro unit, as the system is designed to clean itself, and there are no filters that need replacing. The tank also contains a horizontal piston, which breaks down iron and prevents it from building up in the valve, reducing your need for professional maintenance. 

For viewing and amending the system’s settings, the IronMaster has a digital control screen with touchpad functionality. You can assess the system’s current settings on the screen, which is backlit, making it easy to read even in dark spaces. 


  • Uses no chemicals to remove contaminants from water
  • Removes up to 30 PPM of iron
  • Good value for money


  • Installation may require a professional
  • Water flow rate may not be ideal for larger homes

Well Water Filter System Buyer’s Guide

It’s can be a big decision to select the right well water filter for your needs. To do so, having the appropriate knowledge to make your choice is super important.

That’s why we put together the following buyer’s guide to help you learn everything there is to know about well water filter systems. Enjoy!

Why do I need a water filter for well water?

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

If you drink water from a private well, you may be ingesting bacteria, parasites and other harmful microorganisms that could make you sick. The water most likely also contains minerals that have leached into the water from its surroundings, including sulfur, iron and manganese. These contaminants are dangerous to consume in large doses, and even in smaller doses, they can affect the taste, appearance or odor of water. 

A water filter can trap these contaminants in your water, allowing you access to much cleaner, fresher drinking water for your whole home. 

How does a well water filter system work?

Well water filters are usually recommended for installation at your home’s point of entry for water. When water flows through a pipe into your home, it will have to pass through the filtration system before it is used at any point.

Inside this system, one of several processes may be used to filter the water and make it cleaner. Some whole home well water filters use a number of filters, which trap contaminants and prevent them from passing through with water. Some systems use chlorination technology to disinfect the water, or a process called air injection to oxidize iron and manganese. You can also find whole home well water filters that include a UV lamp, which uses ultraviolet light to kill bacteria, some viruses, and other living organisms that are often found in well water. 

What contaminants does a whole house water filter for well water remove?

There is no set list of contaminants that a well 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. 

In every case, a well water filter should be able to reduce iron. It’s also common for well water filters to reduce heavy metals, manganese and sulfur, though different filters do this to a different level. Ideally, for the safety of you and your family, you should look for a well water filter that kills living microorganisms. 

Some well water filters can be used for city water too, and are designed to remove chlorine from water. As chlorine is added to water during the water treatment process, it’s likely that your chlorine content will be much higher if you have city water than if you have well water. For that reason, chlorine removal is generally less important for well water. 

How To Remove Iron From Well Water

The easiest way to remove iron from your well water is to find a filter that will do it for you. The first stage is to use the oxidizing process, which oxidizes ferrous iron into its ferric form, converting it into a solid. This means that the iron can then be filtered using a variety of iron filters. 

Manganese greensand, for example, uses an oxidizer called potassium permanganate. This traps the ferric iron particles, which are then flushed out with the system when it regenerates. The process is repeated as water travels through the system, oxidizing the iron and flushing it out at a constant rate. There are also iron removal filters, which use an oxidizing agent that converts iron to ferric, then catch the iron in the media. Often, this media is made from KDF, a material that is particularly effective at creating an oxidizing chemical reaction to convert the iron. 

iron filter for well water

Well water filters vs water softeners

It’s important to be aware that well water filters and water softeners are not the same. In some cases the process of contaminant removal may look the same, such especially in well water filters that use an oxidation process and flush out iron particles. But both systems are designed with completely different purposes, and you won’t be able to use a water softener to make your well water clean and safe to drink. 

The role of a water softener is to remove hardness causing minerals, like magnesium and calcium, from water. These minerals can cause scale in plumbing and appliances, and can affect the lifespan of an appliance and prevent it from working efficiently. 

A water softener usually uses the ion exchange process to replace these minerals with sodium, though there are also salt-free softeners that change the structure of the minerals, preventing them from sticking to surfaces. 

Unlike water filters, water softeners can’t remove any well water contaminants like iron, heavy metals, manganese. They especially aren’t capable of killing harmful biological contaminants in drinking water. Both serve their purpose – and you may find that you need a water softener as well as a well water filter – but the two can’t be used interchangeably. 

Key considerations when buying a well water filter

Well water filters can cost upwards of $2,000, so making sure you’re well informed before making a purchase is essential. It’s wise to consider the following when deciding on the filter for you:

Your available space

There are a number of different types of well water filters, and some take up more space than others. Systems with multiple filters and add-ons will need plenty of room, especially if regular maintenance is required. Be sure to measure your available space carefully before buying a unit that could potentially be too big. 

Maintenance requirements

Depending on the type of well water filter you go for, you will need to factor in for different maintenance requirements. Any system that has a filter will require extra work in making filter replacements, usually after 8 to 12 months of use. This can hardly be classified as extensive maintenance, but new filters do come at a cost.

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. 


There are a number of different certifications that a well water filter can have, and this largely depends on the components in the system and the benefits that the system provides. If a filter has been either third party tested to meet NSF Standards, or certified by the NSF itself, it’s a promising sign to you, the customer, that the system does what it claims to do. While a filter with no certifications may still work, you might choose to opt for a certified filter for peace of mind.

Your water pressure 

You need to understand how your own well water system works, and how this affects your water pressure, to ensure you buy the right well water filter for your needs. Additionally, the flow rate of a filter, measured in GPM, will help you to determine how quickly it will send water to all of your home’s appliances. You need a filter that won’t cause a distinct drop in pressure, and has a high enough flow rate to send water through your plumbing at a fast enough rate.


Some well water filters can be installed by the customer, while others recommend professional installation by a plumber. The best way to determine the difficulty of installation is to read customer reviews. If the overwhelming majority of customers have been able to install their system themselves, assume that you can, too. You might not be fussed at having to pay extra for professional installation, but if your budget is tight, it’s worth finding one that you can manage yourself.

How to choose the right size well water filtration system

The size of your well water filter depends predominantly on your family’s water needs. Generally, the larger the system, the higher the flow rate. A higher flow rate allows water to travel at a faster speed to all of your home’s appliances. 

If you have a larger home, with multiple bathrooms and three or more appliances running at once, you’d benefit from a bigger well water filtration system. This will ensure that your water flow rate is high enough to allow your faucets and showers to perform at their best simultaneously..

A 4.5” by 20” filter is the most popular size for medium to large families. Systems can go larger than this, especially with add-ons like UV lamps. It’s wise to speak to an advisor about your needs if you’re uncertain. Many manufacturers are happy for their representatives to chat to you about their different products if it may end in a purchase. 

Installation and Maintenance of a well water filtering system

It’s possible to install most well water filtration systems yourself, which will save you the cost of hiring a professional. We’ll keep things generic with this step-by-step installation example. You’ll need to read your own system’s instructions carefully before getting started. 

  1. Choose your filter location – You need to install your filter as close to your water’s point of entry into your home as possible. This is so that all your appliances and plumbing can benefit from filtered water. Be sure to choose a location where there is enough space for maintenance. 
  2. Cut your water pipe – Turn off your water supply, then mark your pipe, checking your filtration system’s instructions for guidance. Cut the pipe to make room for the filter and its fittings. Catch any remaining water with a bucket placed underneath the pipe.
  3. Assemble and install your filter – At each end of the water line, install a shut-off valve. Then connect your assembled system using the fittings provided. Some well water filters don’t provide all the fittings you’ll need, so be sure you’ve made the necessary purchases before getting started. 
  4. Turn your water supply back on – When everything has been fitted correctly, you can turn your water supply back on and check for leaks. If there are leaks, use plumbers tape to better secure the fittings. It’s important not to over-tighten the fittings. 

Not all well water filtration systems require maintenance. Here’s the work you can expect to do for each of the most popular systems:

well water filter system

Systems with a filter

For well water systems with one or several filters, you will need to change these filters according to your manufacturer’s guidelines. This is usually between 8 and 12 months. Filter changes don’t need to be done by a plumber; you just twist or click the old one to take it off, and add the new one in its place. 

Systems with a UV filter

If you buy a system with an added UV filter, the lamp will need changing after approximately a year. Again, this is very simple, and you’ll be able to find plenty of video material online if you’re unsure. You’ll also need to clean the UV lamp’s housing every couple of months.

Systems that use air injection technology

In the majority of cases, systems that use air injection or oxidize iron in your water will automatically backwash their insides, cleaning themselves. You will also need to make sure that the system regenerates frequently, which it should do automatically. 

In general, you should test your well water once or twice a year to check that there are no new contaminants that you need to remove. 


How do I know what my well water contains?

Simple: get your water professionally tested. Many businesses can provide you with an extensive report of the contaminant levels in your well water. You can use this report for reference when deciding on what you’re looking for in a well water filter. 

According to testing, my well water contains bacteria. Will a filter remove this?

In most cases, no. The majority of well water filters are designed to remove iron, sulfur, manganese, and chemicals like pesticides and herbicides. You should add a UV lamp to your system if you want to rid your water of bacteria. UV light alters the DNA of bacteria and prevents it from causing harm or spreading. 

Which is best: a system using filters or air injection technology?

It depends on what you’re personally looking for. Filters remove a broader range of contaminants, though some, like chlorine, aren’t much of a problem in well water. Air injection technology focuses more on iron, sulfur and manganese removal. It has the added benefit of requiring little to no maintenance, while filters will need changing. 

Can I install my well water filter outside?

Some filters are designed for outside installation, but others may not appreciate being subjected to icy temperatures in the winter. The majority of filters are designed for installation at water’s point of entry into your home. Be sure to check with a manufacturer before purchasing a system that you plan to install outside.
