Whole House Well Water Filtration Buyers Guide

Of the 60-million plus private well owners in America, more than half have serious water quality issues that could benefit from filtration. But choosing the best whole house water filter for well water is both a challenge and an investment, so you want to get it right the first time. There’s a lot to learn, and we want to help. Let our comprehensive buying guide be your key to choosing the best system for well water.

Why You Should Test Your Well Water

Although your well water may look clean and smell great, you should still test it to ensure that the minerals found in the water are safe for consumption. It’s important to know what minerals are in your water because certain ones can be good for you while other ones are known to cause health problems.

If you don’t regularly test your well water, you’re at risk of ingesting harmful minerals in your everyday drinking water. Knowing the exact content in your well water will give you peace of mind that it’s safe to drink.

Having your well water tested by a professional lab is the best way to go – have a look at some top rated water testing kits here.

Common Contaminants Found in Well Water

Well water is generally thought to be a safer and healthier source of drinking water than municipal water supplies, but this is not always the case. Wells can be contaminated by a variety of factors, including surface water runoff, pesticides and herbicides from agricultural operations, septic systems, malfunctioning well pumps, and corrosion of well casing and piping.

The most common water contaminants that are found in well water include:

• Iron
• VOC’s
• Radon
• Sulfur
• Manganese
• Nitrates
• Coliform Bacteria
• Heavy Metals (such as lead)
• Radionuclides (such as uranium)

Why You Need a Whole House Water Filter for Your Well Water

Municipal water is continually monitored and disinfected. The EPA sets strict limits for hazardous substances from toxic chemicals to disease-causing bacteria, so the public is assured what they drink is safe. But private wells have no regulatory safeguards. While many homeowners believe their supply is immune from contamination because it comes from underground where it’s filtered naturally through the soil, the truth is — unfiltered well water is risky.

More than 60 million Americans get their water from private wells, but at least 20 percent are contaminated. In a 2009 study, the USGS found one in five had harmful levels of hazardous substances from toxic chemicals to disease-causing bacteria. Others had hard water — high levels of calcium and magnesium that are healthy but take a toll on clothing, plumbing and appliances.

A water test can tell you what’s in your water today, but because contamination risks in your watershed from landfills to industry change over time, there’s no guarantee it will stay the same. Only a well water filtration system can protect you both now and in the future.

Types of Well Water Filtration Systems

There are two broad categories of whole house water filter systems for wells. Point-of-use systems treat water from a single tap for drinking and cooking — examples including filtration pitchers and under-sink filters. Whole-house well water filters water as it enters your home, guaranteeing that water from every tap is as pure as possible.

Filters are further categorized by filtration method — each targets different water contaminants. The best whole house water filter for wells are typically multi-stage, utilizing several types of filters to achieve maximum contamination reduction.

Whole House Filters for Well Water

There are seven basic types of whole house water filters:

Sediment Filters

They work like strainers, removing large suspend particles too large to fit through their microscopic pores. They’re ideal for reducing taste and aesthetic impurities, making water clear and more pleasant to drink. In a multi-stage system, they protect other types of filters prone to sediment clogs, but they don’t remove chemicals, bacteria or minerals.

Carbon Filters

Carbon filters work by adsorption, permanently trapping organic contaminants in their pores. A single gram of carbon has a surface area of 32,000 square feet, making it the ideal filtration medium. The amount and quality of granules determines a filter’s efficiency and lifespan.

Carbon filters excel at removing select heavy metals and chemicals from disinfectants to pesticides, refining both the taste and safety of water. Like sediment filters, they’re also used as pre-filters to protect delicate reverse osmosis membranes.

Reverse Osmosis Filters

Reverse osmosis filters purify water by forcing it through a semi-permeable membrane. Pores are significantly smaller than those in sediment filters, removing the tiniest particles sediment and carbon filters can miss. RO systems eliminate the highest percentage of contaminants possible, but they’re slow, and they create wastewater. They remove some but not all pathogens.

KDF Filters

KDF — Kinetic Degradation Fluxion — filters contain high-purity copper and zinc granules to reduce organic contaminants in water via oxidation-reduction. It’s used primarily to reduce chlorine and higher percentages of dangerous heavy metals like lead.

UV Filters

UV filters use ultraviolet light to treat microorganisms by rendering them unable to reproduce. Bacteria that can’t multiply cannot cause disease. It’s the highest level of pathogen treatment on the market short of chlorination.

Water Softeners

Hard minerals are healthy for the body, but they cause limescale buildup in pipes leading to high utility bills and appliance breakdowns. If hard water is a problem, softeners are the only cure. Their sole mission is to remove minerals via ion exchange, trapping them in resin to be flushed away.

Salt-based softeners are effective but increasingly unwelcome in ecologically sensitive areas because the briny wastewater they produce is bad for the environment.

Water Conditioners

Water conditioners, also know as descalers or salt-free softeners, change the chemical composition of calcium and magnesium so they can’t form limescale. They’re not quite as effective as traditional softeners, but they’re inexpensive to use, produce no wastewater, and they do not remove beneficial minerals. Water conditions are welcome everywhere.

Which contaminants does a well water filtration system remove?

The contaminants a whole house water filter removes depends on the combination of filtration methods used.

Sediment filters remove any debris larger than its pores, including:

• Dirt
• Dust
• Silt
• Sand
• Rust

Carbon filters reduce:

• PFAS
• Phosphate
• Select heavy metals
• Chlorine
• Chlorine byproducts, including bromate and haloacetic acid
• Pesticides
• Herbicides
• Industrial solvents and more

The level of reduction depends on the quality of the whole house water filter systems you choose. Carbon block filters have more surface area and are considered superior to granular activated carbon (GAC) filters for most applications.

Reverse osmosis systems are the gold standard for filtration. When equipped with sediment and carbon pre-filters, they virtually eliminate all of the above organic contaminants plus:

• Fluoride
• Minerals
• Some arsenic
• Select microorganisms

KDF filters remove:

• Chlorine
• Hydrogen sulfide
• Mercury
• Lead

Manufacturer often pair KDF and carbon filters for maximum lead removal. KDF also inhibits the growth of bacteria and fungi, keeping filters cleaner and enhancing their longevity.

Water softeners remove only minerals, including:

• Calcium
• Magnesium
• Barium
• Lead
• Iron less than 5 PPM

They reduce no chemicals or pathogens.

How to Remove Iron from Well Water

High levels of iron in well water cause tough orange stains in your toilet and tub, but what’s worse, it can clog pipes and give water a bitter, metallic taste. There are two types of iron found in wells — ferric iron, large particles of rust you can see and ferrous, or dissolved iron.

Sediment filters remove ferric iron, but only a water softener reduces ferrous iron. The catch is that ferric iron can damage softening media, so it must be removed first. The best iron whole house water filter system will come complete with an inline sediment filter.

Not all softeners can remove large quantities of iron. If you have levels above 5 ppm, the best way to remove iron from well water is with a special softener equipped with oxidation technology that turns ferrous iron into ferric iron and confines it in a separate tank.

How to Filter Coliform Bacteria in Well Water

Coliform bacteria rarely cause disease, but it suggests other more dangerous types of fecal bacteria could be lurking in your well. So while RO and carbon filters remove coliform bacteria, only chlorine or UV light protect you from microorganism like E. coli.

Home chlorinators are ideal for heavily chlorinated wells — it’s like having a private treatment plant in your basement — but they’re not cheap, and they require a fair amount of maintenance. UV filters are a simple and economical alternative.

How to Filter Arsenic from Well Water

Arsenic is a chemical element. It’s found in nature and can contaminate underground water supplies in select areas. Most water whole house water filters and even softeners remove arsenic to some degree, but it’s less than most homeowners would prefer given its toxicity — even RO systems remove less than 90-percent.

The overall risk of arsenic contamination is low for most people, but if you live in an area where it’s a concern, the best well water filtration systems would be a salt-based softener or RO system with an added active alumina cartridge for optimal reduction.

What to Look for in a Whole House Water Filter For Wells

Consider these key features when shopping for whole house filtration systems:

Contaminant Filtration Capability

The best well water filter is the one that removes target contaminants without breaking the bank. What are target contaminants?

Target contaminants are substances tests show are in your water now or could be in the future. Is there a landfill in your watershed or a large farm that uses pesticides? Do you live in an area where frequent floods could introduce bacteria to a shallow well?

A water test and a little research into the risks in your area will help you identify target contaminants. All that’s left to do then is to determine your budget and choose a whole house water filter that removes the most substances for what you can afford.

System Type

Filter media type determines which substances are removed. If you need the best way to remove iron from well water, your choices are limited, but if lead is the problem, you could choose from carbon, KDF or RO filtration. As a general rule, the best well water filter system is one that removes target contaminants for the lowest cost, but peace of mind counts, too.

Whole-home filters treat every gallon your family uses, but systems can be cost-prohibitive, and they may not be an option if you rent. Point-of-use filters treat only the water you drink and cook — eliminating most, but not all, health risks for a fraction of the price. Only you can choose a system you’re comfortable with.

Capacity

Non-RO water filters produce water on demand — there’s no maximum daily number of gallons they will filter — but reverse osmosis systems are limited. Quality filtration takes time, so they can only produce so much in 24 hours. Consider your family’s usage and choose only systems that meet your needs. Fair warning — whole home RO systems cost so much they’re impractical for most homes. If you need RO capability, shop for a point-of-use system.

Flow Rate

A common complaint about whole house well water filters is that they reduce water flow at the tap. No one wants their shower to turn into a trickle every time the kids flush the toilet.

Flow rate, measured in gallons per minute, determines how many water-using activities your family can do simultaneously without noticing a reduction in water pressure. If the flow rate is too low, it’s unlikely you’ll be satisfied with your filter long-term.

Since most water-using household activities require 2–3 gallons per minute, a minimum flow rate of 6 gpm is a must for a family of four. Most systems average 6–7 gpm, but some run as high as 20 or more.

Well Pump Flow Rate

You might not be aware of this important detail. However, it’s very important to know what your “effective flow-rate” is, so that you can purchase the right size whole house filter system for your needs.

How to Calculate Your Well Water Flow Rate

1. Make sure all water faucets indoors is closed off and not running.
2. Grab a 5 gallon bucket and locate your spigot nearby your well pump.
3. Begin filling up your 5 gallon bucket and set a timer on how many seconds it takes to fill up.
4. For example: 5 GPM would be roughly 60 seconds to fill up a 5 gallon bucket. See our chart below.

Micron Rating

A filter’s micron rating reflects the size particles it will remove — the lower the number, the finer the molecules it excludes. The best sediment filter will have a micron rating no lower than five — meaning it filters contaminants larger than five millionths of a meter. Sediment pre-filters that block more than tend to clog.

RO membranes have much lower micron ratings — between 0.01 and 0.0001 microns — for comprehensive filtration. They’re capable of removing even the smallest bacteria, but only because sediment pre-filters catch larger particles first.

Average flow-rates of household appliances and fixtures

For those that don’t know, the average American household uses roughly 300 gallons of water per day, according to the EPA.gov.

I know what your thinking…300 gallons of water per day? sure.. However, if you think about how many times you flush the toilet, run the sink, do laundry, shower and run the dishwasher — the gallons of water used do add up.

Calculate your own daily water usage by checking your water meter in the morning and at night and take the 7 day average to help understand your water usage, or have a look at our chart below:

Professional Well Water Filtration Installation Costs

Ownership Costs

There’s more to consider when buying a whole house water filtration system than its initial cost — maintenance is a factor. Capacity — the number of gallons a system can treat before filters should be replaced — plays a significant role in long-term ownership costs. Let’s look at an example.

A $500 filtration system with a activated carbon filter and sediment prefilters that need changing every three months at $60 each will cost $240 to operate annually. A similar model with extra-capacity filters that are changed every six months reduces yearly maintenance totals to $120, saving you $1200 over ten years.

Cost isn’t everything when it comes to whole house water filters — capability matters. But when features are equal, why not keep your money in the bank?

Maintenance

For most homeowners, the best well water filtration systems is the one they need to think about least. Complex systems requiring continual or technically challenging maintenance are a hassle.

Dependent on the well water filtration system you choose, you will need to replace the filter every 6 to 12 months. This can be a costly and time-consuming process, so it is important to consider these factors before you make a purchase.

You’ll need to decide if you’re willing to spend a little bit more upfront to eliminate some of these annual costs.

Look for these helpful features:

1. Tool-free filter changes
2. Extended life cartridges
3. Filter change indicators
4. Bypass valves that allow filter swaps without shutting off the main water supply

For water softeners, choose salt-free models unless you have the hardest water. What you’ll save in salt and utility costs more than outweighs the marginal difference in performance.

Certifications

Independently certified whole house water filters are guaranteed to perform as advertised, but are they worth the extra cost? NSF and Water Quality Association certification programs are voluntary and costly for manufacturers, so not all companies participate. Instead, most assemble systems from certified components.

If you stick with a reputable brand, certifications are a point in a product’s favor, but they shouldn’t be the sole determinant of quality.

Read our guide on “What NSF Certified Means Exactly.”

Support

Cheap water filters can seem like a bargain, but what happens after the sale? Does the company support installation? Will it help troubleshoot performance? Are replacement parts available? What about the warranty? A whole house water filter is an investment. Choose to work with companies that respect what you’ve spent.

Understanding Warranties and What To Look For

This is an important step for any buying process — understanding the type of warranty you will get. There’s nothing worse than to come home to a leaky water tank and to find that the most expensive part isn’t covered under their “limited lifetime warranty.”

So it’s very important to read the companies full terms of service before making a large purchase — this goes for anything in life, really.

So choose the right company/brand that stands behind their filtration systems with a iron-clad warranty and generous return policy.

Money-back Guarantees – What You Should Know

Money-back guarantees are to be expected, especially for how much these filtration systems cost. Having the ability to test drive your filtration system for longer than 30 days would be ideal so that you have time to decide before committing long term.

However, not all trial periods are equal and some product return policies might leave you with less money than you started with, so it’s important to read the terms & conditions.

30/60/90 day trial periods are all great and dandy, however, if they have restocking fees you’re not going to be to pleased. You also want to be sure that you will not be responsible for return shipping — depending on the water tank size, this could be a huge cost.

Well Water Filtration FAQ’s

Which company makes the best well water filter system?

No one can predict every consumer’s experience, but select brands have an undeniable reputation for quality, durability and customer care. These are our top picks:

Best Carbon Filter

iSpring

iSpring makes the industry’s best carbon filter for well water. They use only the highest quality block carbon for maximum filtration efficiency and filter life.

Express Water’s food-grade multilayered sediment prefilters are safe, efficient and long-lasting. Replacements are affordably priced.

Best Iron Filter

SoftPro

The best way to remove iron from well water is with a specially designed water softener. SoftPro Iron Master systems use air injection system to maximum iron removal up to 30 ppm— three times more than the competition. It’s the best iron filter with the highest levels.

Pelican makes perhaps the best whole home iron filter for wells with bacteria. It chlorinates water and removes up to 10 ppm of iron — it’s not cheap, but it makes heavily contaminated water biologically safe to drink.

Other manufacturers we trust include:

Aquasana

The EQ-WELL-UV-PRO-AST Filter System is our pick for the most comprehensive system. It conditions water, filters maximum contaminants and includes a UV filter for one low price.

SpringWell

SpringWell has twenty years of experience in the filter industry. Their 1,000,000-Gallon Whole House Well Water Filter System is a top performer and our best budget pick. Quality catalytic coconut shell carbon filter and KDF media target the highest number of organic contaminants, and it’s virtually maintenance-free for low long-term cost of ownership.

What does the best whole home well water filtration system cost?

Unless you’re on a strict budget, we urge you to consider value over the initial price. Capable whole-home systems start as low as $300, but they tend to require more maintenance over the long haul. Better systems cost two to three times as much initially, but you’ll save money and spend less time worrying about filter changes.

Expect to pay as much as $2000 for systems that filter and condition water. Still, these all-in-one units are typically more cost-effective than installing a filter and softener separately, and components are made for each other — there’s no worry about system compatibility.

What type of filter do I need?

If you need reverse osmosis capability, choose an under-sink filter. Filter pitchers make water taste better but only in limited quantities. Under-sink models provide plenty of healthy water for drinking and cooking plus filling travel bottles for pennies on the dollar.

Otherwise, we recommend whole-home water filters. Many are as inexpensive as point-of-use systems while offering the highest water quality throughout your home — you’ll never have to worry about which bathroom faucet the kids are drinking from.

Can install a well water filter myself?

Most of today’s whole house water filters are engineered for DIY installation. Under-sink water filters require no technical expertise, and manufacturers go out of their way to make it easy with color-coded components and video instructions. It incentivizes sales.

Whole-home systems are also do-it-yourself friendly, but installation requires cutting into the main water line, so comfort with basic plumbing is helpful. A few companies request professional installation in change for a full warranty. Consider the cost — $350– $550 — when pricing out systems.

How are whole house well water filters installed?

The process varies based on the model, but for a whole-home system, you’ll have to:

1. Shut the water off at the inlet
2. Plumb the system into your water line
3. Restore water and check for leaks

For under-sink systems:

1. Turn the water off at the sink
2. Assemble the filter with cartridges in place
3. Connect the cold water line to the filter
4. Connect the filter to the faucet
5. Restore water and check for leaks

How do I maintain a whole house well water filter?

For standard water filters, maintenance is as simple as changing cartridges per the manufacturer’s recommendations. Select RO systems may require annual storage tank cleaning that’s time-consuming but not difficult to do.

For systems with integrated salt-based softeners, replace salt as needed in the brine tank and backwash the system weekly to prevent the growth of bacteria in the softening tank. Salt-free conditioners need only a backwash.

UV lights should be changed precisely as directed. They can lose purifying strength without becoming noticeably dimmer. Most last a year.

Do I have to filter well water?

It isn’t necessary to filter well water if testing shows no worrisome contaminants. Yet many homeowners choose to because it enhances taste or softens water and safeguards appliances. Others just feel safer protecting their family against the unknown. Remember, only a water test can tell you what’s in your water, but only a filter can protect you from what’s in it.

How often should I replace a whole house well water filter?

Filter components should be changed as directed, but with proper care, frames, housings and fittings can last a lifetime. A few high-capacity models with single disposable tanks are discarded when they’ve reached capacity — usually a million gallons or more. But these models require no maintenance and can be the ultimate value for homeowners who want a fix-it-and-forget-it filter.

What water filter works best with well water?

This will come down to having a proper water test to see what contaminants you will need to remove. Having said that, the SpringWell WS does a great job at handling most common contaminants found in well water.

Where do you put a sediment filter for well water?

A sediment filter should be connected to your main water line before your filtration media tank. This will ensure all heavy metals don’t enter your tank.

What micron filter is best for well water?

In most cases, you’ll find the best sediment filter options for well water have micron rating of 5 to 50. However, for very fine sediment, look for a range of 1 to 5 microns.

Final Thoughts

The best whole house water filter for well water is one that brings you peace of mind — fewer investments can impact your health more. If your water isn’t as pure as it should be, a well water filtration system is a simple, cost-effective solution. It’s a gift to yourself and your family that can last a lifetime.
