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

It’s can be a big decision to select the right whole house filtration system for your needs. Having the appropriate knowledge to make your choice is essential.

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

🤔 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, 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, manganese and heavy metals. These contaminants are dangerous to consume in large doses, and even in smaller amounts, they can affect taste, appearance, odor, and overall water quality. 

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

🧪 Importance of Well Water Testing

Well water is untreated. meaning that it may contain traces of harmful drinking water contaminants. 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 as follows:

  • 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
  • Nitrate – flooded sewers or septic systems, local geology 
  • Manganese – derived from sediments and minerals in the earth 
  • Radon – naturally occurring in rocks and soils
  • Sulfur – oxidized sulfur ores in the ground

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. 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. 

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

iron filter for well 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. 

Most water filters aren’t capable of removing coliform bacteria, given its microscopic size. The best coliform bacteria removal solutions are whole house water filtration systems that kill the bacteria, rather than filter it out.

UV purification is one of the most popular methods of removing coliform bacteria. This method involves treating water with ultraviolet rays, which damage the DNA of bacteria and inactivate them, preventing them from reproducing or causing illness. 

Distillation and reverse osmosis can also be used to remove coliform bacteria, but these systems are less commonly used as whole-home applications. 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 can cause 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. These treatment methods are slightly more specialist, and most standard whole home filters won’t offer guaranteed arsenic removal.

Oxidation filters are designed 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 capable of removing larger 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 use the ion exchange process to replace hardness minerals with salt. A water softener can remove:

  • Calcium
  • Magnesium
  • Low levels of iron

Reverse Osmosis Systems

Reverse osmosis filters provide a thorough multi-process filtration solution and can 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. 

Check a product’s marketing information to see exactly which contaminants it can remove, and to what level of effectiveness.

🆚 Well Water Filters vs Water Softeners

Well filtration systems and water softeners are not the same. In some cases, the process of contaminant removal may look the same, especially in whole house filters that use an oxidation process and flush out iron particles. But both systems are designed with completely different purposes. 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 can cause scale in plumbing and appliances. They can affect the lifespan of an appliance and prevent it from working efficiently. 

A water softener uses the ion exchange process to replace these minerals with sodium. You’ll need to keep this type of whole house water softener well stocked with salt, and it requires backflushing to maintain consistently high performance.

There are also salt-free softeners that change the structure of the minerals, preventing them from sticking to surfaces. These don’t need salt to operate, and require less maintenance than an ion-exchange whole house water softener.

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.

💭 Key Considerations When Buying Whole House Filtration Systems

Well water filtration systems 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 filtered water system for you:

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. Generally, the more contaminants a filter can remove, the more money it will cost – but the better systems are worthy investments.

System Type

The type of system can affect size, performance, price, and maintenance requirements, so it’s an important factor to consider when you’re shopping around.

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

The type of system you opt for will largely depend on the contaminants you want to remove, as different system types are designed to remove different contaminants.

Filter Capacity

A filter’s capacity is the amount of water it can deliver to your home per day. It’s important to buy the right capacity system to ensure you get enough filtered water to meet your daily demands.

Flow rate and tank/filter size can all tie into capacity. The bigger the unit and the more water it can produce per minute, the bigger its capacity. You should look at how much water you use every month to determine the minimum capacity well water filtration system you need.

Most systems will tell you what sized home they’re suitable for (e.g. 1-3 bathrooms) in their product descriptions, but if you’re unsure, contact the manufacturer for guidance.

Water Pressure & Flow Rate

The water 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 water flow rate to send water through your plumbing to meet your demands. Low pressure may affect the water-based appliances in your home. You may find that if you have multiple appliances operating at once, there isn’t a enough water to keep them all running properly.

Your home’s ingoing water pressure is something to consider, too. Most well water filtration systems can only work with a minimum pressure of 40 PSI and a maximum pressure of 100 PSI. A water pressure that’s too low may mean that water doesn’t have enough force to pass through the multiple filtration stages, including the pre- and post- filter, in a whole house water filter. A water pressure that’s too high may damage the filters.

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

Depending on size and design, 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 that could potentially be too big. You’ll need to install your whole house water filter as close to your home’s point of entry as you can, whether that’s in your basement or elsewhere, 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.


Some of the best whole house filtration systems can be installed on a DIY basis, but many manufacturers recommend professional installation by a plumber. Installing a whole house water filter yourself means you won’t need to spend an extra few hundred dollars for a plumber to install it for you. However, if you’re not very handy, you might struggle with the job.

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. You might not be fussed at having to pay extra for professional installation, but if your budget is tight, it’s worth finding a whole house well water filtration system that you can install yourself.

Maintenance Requirements

Depending on the type of well water filter you go for, you will need to factor in 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. 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.

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 lamp, keep in mind that the lamp will need changing once a year, and you will need to clean the sleeve to keep it working well.


There are a number of different certifications that a whole house 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 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 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. Third-party testing is still a good sign, but it’s not quite as reassuring as being officially NSF certified.

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 your filter’s entire lifespan should anything go wrong. Not all manufacturers offer a lifetime warranty, though, and even a 5 or 10-year warranty is pretty good.

Aside from warranties, some filter manufacturers also offer a 6-month money-back guarantee, which entitles you to a full refund within 6 months if you’re not impressed with the quality of the filter. This is another great way for companies to reassure customers that their product will live up to expectations.

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 media tend to be cheaper to operate in the long-run as they require fewer maintenance duties. Rather than paying for new filter cartridges every few months, you will only need to pay for media replacements every 6 years or so.

📌 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.

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. You will need to rule out certain systems if they don’t remove your well water’s problem contaminants.

Some systems may also be out of your budget. Narrowing down your options will make it easier to choose the best whole house well water filtration system for your requirements.

3) Determine the System Size

Once you have an idea of the system types 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 will be 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.

❔ FAQs

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

It depends on what you’re personally looking for. Whole house water filters remove a broader range of contaminants, though some, like chlorine, aren’t much of a problem in well water. The best whole house air injection technology focuses more on iron, sulfur and manganese removal. An ait injection system will require 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 do well if they’re subjected to icy temperatures in the winter. The majority of whole house water filters are designed for installation at the 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.

Should I use a softener system for well water?

Perhaps you’ve already established that you need a well water whole house filter, but how about a softener? If you’re dealing with hard water issues, such as problems with water flow and scale formation, test your water for hardness. High hardness levels usually can’t be treated with even the best well water filtration system, so you’ll need a separate well water whole house softener for the job.

Can I use a reverse osmosis filter for my well water?

Yes. Reverse osmosis is one of the most effective well water whole house filter options. RO systems can’t deal with high levels of hardness, however, as calcium and magnesium will cause fast deterioration of the RO membrane. Iron bacteria will also damage the RO membrane. However, these systems can still filter and soften water with low hardness levels.
