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:
- Coliform Bacteria
- Heavy Metals (such as lead)
- Radionuclides (such as uranium)
|Noticeable Changes||Test Your Water For:|
|Corroded pipes or plumbing||Corrosion, pH, lead|
|Stained Laundry or plumbing fixtures||Iron, copper, manganese|
|Foul taste or odor, rotten egg smell||Hydrogen sulfide, corrosion, metals|
|Salty taste||Chloride, total dissolved solids, sodium|
|Scaly residues, soaps don’t lather||Hardness|
|Water appears cloudy, frothy or colored||Color, detergents|
|Dump, junkyard, landfill, factory, gas station or dry-cleaning operation nearby||Volatile organic compounds, total dissolved solids, pH, sulfate, chloride, metals|
|Rapid wear of water treatment equipment||pH, corrosion|
|Recurring gastro-intestinal illness||Coliform bacteria|
|Nearby areas of intensive agriculture||Nitrate, nitrite, pesticides, coliform bacteria|
|Gas drilling operations nearby||Chloride, sodium, barium, strontium|
|Odor of gasoline or fuel oil, and near gas station or buried fuel tanks||Volatile organic compounds|
|Household plumbing or service lines that contain lead||pH, lead, copper|
Why You Need a Whole House Water Filter for Your Well Water
Municipal water is closely monitored and disinfected, ensuring it meets strict EPA standards for safety. Private wells however do not have such regulatory safeguards in place, making them a riskier choice as contamination can occur.
A USGS study found one in five private wells was contaminated with hazardous substances or bacteria. Water tests can tell you what’s in your water today, but a filtration system is the only way to be sure you’re protected now and in the future.
Types of Well Water Filtration Systems
Whole house water filter systems for wells come in two categories: point-of-use, which treats water from a single tap, and whole-house, which filters water as it enters your home.
The best whole house filter systems are multi-stage and use several types of filters to reduce the most contamination possible. Enjoy pure, clean water from every tap with the right whole house filter for your well.
Whole House Filters for Well Water
|Brand||KDF Carbon Filter||Oxidation||Adsorption||UV||Softening or Conditioning|
|Pentair Iron & Manganese Combo||✔️||✔️||✔️|
|US Water Systems||✔️||✔️|
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: work by adsorption, permanently trapping organic contaminants in their pores, and 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: 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: 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: 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?
|Filter Type||Contaminants Removed|
|Air Injection Systems||Iron, Manganese, Hydrogen Sulfide|
|Carbon Block Filter||Organic chemicals, unpleasant tastes & odors|
|Sediment Filter||Silt, rust, metals and suspended particles|
|KDF Filter||Heavy metals|
|UV Filter||Bacteria and viruses|
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:
Carbon filters reduce:
- Select heavy metals
- Chlorine byproducts, including bromate and haloacetic acid
- 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:
- Some arsenic
- Select microorganisms
KDF filters remove:
- Hydrogen sulfide
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:
- Iron less than 5 PPM
They reduce no chemicals or pathogens.
High levels of iron in well water can cause tough orange stains and clog pipes, as well as give water a bitter taste.
To remove ferric and ferrous iron, use an iron filtration system that includes an inline sediment filter.
For higher levels (over 5 ppm), you may need to invest in a special softener with oxidation technology that turns ferrous iron into ferric iron and traps it in a separate tank.
How to Filter Coliform Bacteria in Well Water
Coliform bacteria may not cause illness, but other harmful fecal bacteria could be present in well water. RO and carbon filters address coliforms, yet chlorine or UV light are needed to safeguard from microorganisms like E. coli.
To heavily chlorinate wells, a home chlorinator is an option, though costly and requiring upkeep. A simpler, cheaper alternative is a UV filter.
How to Filter Arsenic from Well Water
Arsenic is a chemical element found in nature that can contaminate underground water supplies in some areas. Standard water filters and softeners remove arsenic but don’t always reduce it to safe levels, while reverse osmosis systems can usually reduce the presence to less than 90%.
For those living in an area with an elevated risk of arsenic contamination, the best option is to install a salt-based softener or RO system with an active alumina cartridge for maximum 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 fits your budget and removes the contaminants found in your water. Have a test done to identify target contaminants, then research potential risks from sources like landfills or farms that use pesticides in your area.
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.
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.
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.
Non-RO water filters produce water on demand, but reverse osmosis systems are limited in output and must meet your family’s usage needs, and can only produce so much water in a 24hr period.
Whole home RO systems tend to be expensive and impractical for most households; consider a point-of-use system instead – If you need RO capability, shop for a point-of-use system instead.

|Aquasanna EQ||500,000 Gallons||7 GPM|
|SoftPro IronMaster||600,000 Gallons||10 GPM|
|Pentair Iron & Manganese||600,000 gallons||7 GPM|
|US Water Systems||500,000 gallons||10 GPM|
|Express Water||100,000 gallons||15 GPM|
|Ispring||100,000 gallons||15 GPM|
Whole house water filters are often criticized for reducing the flow rate of water at the tap. To ensure your family can perform multiple water-using activities simultaneously, choose a filter with a minimum flow rate of 6 gallons per minute (GPM).
Most systems average 6–7 GPM, but some offer up to 20 GPM or more for larger households.
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.
|Seconds To Fill 5 Gallon Bucket||Well Pump Rate||Seconds To Fill 5 Gallon Bucket||Well Pump Rate|
|76-100||3 GPM||61-75||4 GPM|
|51-60||5 GPM||43-50||6 GPM|
|38-42||7 GPM||34-37||8 GPM|
|31-33||9 GPM||28-30||10 GPM|
|26-27||11 GPM||24-25||12 GPM|
|22-23||13 GPM||21||14 GPM|
|20||15 GPM||19||16 GPM|
|18||17 GPM||17||18 GPM|
|16||19 GPM||15||20 GPM|
|14||21 GPM||13||22 GPM|
|12||23 GPM||11||24 GPM|
Sediment pre-filters with a micron rating of no lower than five can filter out contaminants larger than five-millionths of a meter. RO membranes are even more effective, as they have a much lower micron rating — between 0.01 and 0.0001 — so that even the smallest bacteria is blocked.
However, these membranes are only capable of such thorough filtration because larger particles have been caught by the pre-filters.
Average flow-rates of household appliances and fixtures
The average American household uses 300 gallons of water daily, according to the EPA.
To understand your own usage better, check your water meter in the morning and at night for a 7 day average and calculate your usage with our chart below.
|Fixtures & Appliances||Flow-rate (GPM)|
|Washing Machine||3-5 GPM|
Professional Well Water Filtration Installation Costs
|System Type||Labor||Average Installation Cost|
|Well Water Filtration System||4 to 8 hours||$500 to $1200+|
|Reverse Osmosis System||4 to 8 hours||$500 to $1200+|
|UV Disinfection System||4 hours or less||$350 to $600|
|Softener or Conditioner||4 hours or less||$500 to $1200+|
A whole house water filtration system is more than a one-time purchase — maintenance costs should be taken into account. For example, a $500 system with activated carbon filters that need to be replaced every three months will cost $240 annually.
By opting for high-capacity filters that only need to be changed every six months, you can save up to $1,200 over a decade.
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?
For an easy-maintenance solution, the best well water filtration system is one that requires minimal effort and expense.
Most systems require filter replacement every 6 to 12 months, but investing a bit more upfront may reduce or even eliminate these annual costs. Consider your options carefully to determine what fits your budget and needs.
|Filtration Type||Annual Filter Replacement Cost on Average|
|Well Filtration System||$125 – $275+|
|Cartridge Based System||$150 – $350+|
|Tank Based System||$50 – $150+|
|Reverse Osmosis||$150 – $300+|
|Chemical Injection System||$50 – $250+|
|UV Disinfection System||$75 – $350+|
|Chemical Injection System||$75 – $400+|
Look for these helpful features:
- Tool-free filter changes
- Extended life cartridges
- Filter change indicators
- 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.
Independently certified water filters come with a guarantee of performance, but are the extra costs worth it?
Many companies use certified components to assemble their systems without opting for costly NSF and Water Quality Association certifications.
Although certification is important, other factors such as the brand’s reputation should also be taken into consideration.
Read our guide on “What NSF Certified Means Exactly.”
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
Choose a company that provides an iron-clad warranty and generous return policy when purchasing a water filtration system. Make sure to read the terms of service before buying to ensure that all parts are covered.
This can save time, money, and headaches in the future. Don’t get stuck with a “limited lifetime warranty” for an expensive part!
|Filtration Brand||Warranty||Money Back Guarantee|
|Springwell||Lifetime||6-month money back guarantee|
|Aquasanna||6 years||90 days|
|Pentair Iron & Manganese||5 years||60 days|
|Ispring||1 year||30 days|
|3M Aqua-Pure||5 years||30 days|
Money-back Guarantees – What You Should Know
Money-back guarantees should be expected for such expensive filtration systems. To make sure you’re making the right decision, try a trial period of more than 30 days. Be aware of restocking fees and return shipping costs in the terms & conditions, and check if these are your responsibility.
Look for a 30/60/90-day trial period without fees for a better deal.

Investing in an all-in-one unit for around $2,000 could save you money on the separate filter and softener installation costs. Plus, components are already compatible – no worries about system compatibility.
What type of filter do I need?
If you need the capability of a reverse osmosis system, get an under-sink filter for unlimited healthy water at the tap. Otherwise, go for a whole-home system: it’s just as affordable and ensures the highest water quality throughout your entire home.
Can install a well water filter myself?
Installing a whole house water filter is usually do-it-yourself-friendly, though some companies may require professional installation for a full warranty.
Most systems are easy to install with color-coded components and video instructions, while cutting into the main water line requires basic plumbing skills. Installation costs range from $350 to $550.
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:
- Shut the water off at the inlet
- Plumb the system into your water line
- Restore water and check for leaks
For under-sink systems:
- Turn the water off at the sink
- Assemble the filter with cartridges in place
- Connect the cold water line to the filter
- Connect the filter to the faucet
- 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?
Well water doesn’t have to be filtered if tests show no contaminants, but many homeowners opt for it to improve taste, soften water and protect their appliances. To stay safe from unknown threats in the water, testing is a must but only filtering can give you that extra layer of protection.
How often should I replace a whole house well water filter?
A well water filter should be changed as needed, but with proper care and maintenance, frames, housings, and fittings can last forever. High-capacity models with single disposable tanks may need to be replaced after a million gallons of use but offer the ultimate value for homeowners who want a hassle-free filtration system.
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.
