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 to ensure a safe water supply – have a look at some top rated water testing kits here.

Common Contaminants Found in Wells

While many consider well water to be a healthier alternative to municipal supplies, it’s not immune to contamination. Various factors, from surface runoff to corroded piping, can compromise its quality.

Common contaminants in well water include:

• Iron
• VOC’s
• Radon
• Sulfur
• Manganese
• Nitrates
• 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

Key Considerations

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

• Contaminant Filtration Capability: The optimal filter balances affordability with efficacy. Start by testing your water to pinpoint contaminants. Then, research local risks, such as nearby landfills or pesticide-using farms. With this knowledge, set a budget and find a filter that offers the best contaminant removal within your price range.
• System Type: The type of filter media dictates its purification capabilities. For instance, if iron is your main concern, your options might be limited compared to addressing lead, where carbon, KDF, or RO filtration could be suitable. While whole-home filters purify all the water you use, they can be pricey and unsuitable for renters. On the other hand, point-of-use filters, which treat only drinking and cooking water, offer significant health protection at a more affordable rate.

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

Capacity

When comparing water filtration systems, consider its capacity to filter out contaminants such as sediment, bacteria and other particles from your well water. To do so, keep in mind the following:

• Flow Rate: Measure the gallons per minute (GPM) of your well to determine its water flow rate.
• Total Capacity: Calculate the overall capacity you need based on your daily water usage and how frequently you plan to change filters or cartridges. For example, if you consume 300 gallons a day and want a system to last a decade, opt for one with a capacity rating of 600k-1M gallons.
• Additional Factors: Take into account any specific factors in your area’s water supply, such as sediment levels, hardness, and iron content.
• Micron Rating: Select a filter with an appropriate micron rating that aligns with your local contaminants and your personal preferences regarding taste and odor in your tap water from sources like home wells, rivers, or nearby lakes.

Flow Rate

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)
Dishwasher	1-3 GPM
Washing Machine	3-5 GPM
Shower	2-5 GPM
Toilet	2-3 GPM
Faucet	2-4 GPM

Brand Capacity & Flow Rate Chart

It’s worth noting that whole house water filters can sometimes be critiqued for diminishing water flow at your faucets. To ensure your household can simultaneously engage in various water-dependent activities, opt for a filter with a minimum flow rate of 6 gallons per minute (GPM).

While most systems typically maintain an average flow of 6–7 GPM, certain models cater to larger households, delivering up to 20 GPM or more.

Well Pump Flow Rate

his often overlooked detail can significantly impact your well water filtration system selection. Understanding your “effective flow-rate” is crucial for choosing the right-sized whole house filter system to suit your requirements.

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
10	25 GPM

Micron Rating

Sediment pre-filters with a micron rating of no less than five can effectively remove contaminants larger than five-millionths of a meter. For even finer filtration, reverse osmosis (RO) membranes excel with an ultra-low micron rating, typically between 0.01 and 0.0001. This fine filtration is made possible because larger particles are initially trapped by pre-filters, allowing the RO membrane to achieve thorough purification.

Certifications

The presence of independent certifications on water filters guarantees their performance, but is the added expense justified?

Many companies utilize certified components in their systems without pursuing costly NSF and Water Quality Association certifications. While certification holds importance, it should be balanced with other factors like the brand’s reputation.

In general, the systems we review typically feature one of these certifications:

• NSF/ANSI Standard 53: Signifying a reduction in harmful contaminants
• NSF/ANSI Standard 58: Reserved for reverse osmosis water treatment systems
• NSF/ANSI Standard 42: Focusing on aesthetic improvements, such as reducing chlorine, taste, and odor
• WQA Gold Seal Certification: Assuring structural integrity of filter housing and media containment
• NSF/ANSI Standard 44: Relevant for water softeners and conditioners
• NSF/ANSI Standard 61: Ensuring the integrity of water system components

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

Customer Support

While budget-friendly water filters may appear attractive, it’s crucial to consider what comes after the sale. Does the company offer installation support? Will they assist in troubleshooting performance issues? Are replacement parts readily available? And what about the warranty? Investing in a whole house water filter is a significant decision. Opt for companies that value your investment.

The Necessity of Well Water Filtration

Municipal water undergoes rigorous monitoring and disinfection, meeting stringent EPA safety standards. In contrast, private wells lack these regulatory safeguards, posing a risk of contamination.

A study by the US Geological Survey (USGS) revealed that one in five private wells contained hazardous substances or bacteria. While water tests can inform you about your current water quality, a filtration system is the sole means to ensure both present and future protection.

Methods for Purifying Well Water

Well water purification systems can be categorized into two main types: point-of-use, which treat water from a single tap, and whole-house, which filter water as it enters your home.

The most effective whole house filter systems employ multiple stages and utilize various types of filters to minimize contamination. With the appropriate whole house filter, you can relish in pure and clean water from every faucet in your home.

Removing Contaminants Based on Filter Types

The effectiveness of a whole house water filter in eliminating contaminants depends on the combination of filtration methods it employs. Here are some common filter types and the contaminants they can remove:

1. Sediment Filter

• Removes debris larger than its pores, including:
  • Dirt
  • Dust
  • Silt
  • Sand
  • Rust

2. Carbon Filter

• Reduces various contaminants, including:
  • PFAS
  • Phosphate
  • Select heavy metals
  • Chlorine
  • Chlorine byproducts (e.g., bromate and haloacetic acid)
  • Pesticides
  • Herbicides
  • Industrial solvents, and more
• The level of reduction depends on the quality of the whole house water filter system. Carbon block filters, with their larger surface area, are considered superior to granular activated carbon (GAC) filters for most applications.

3. Reverse Osmosis Systems

• The gold standard for filtration. When equipped with sediment and carbon pre-filters, they virtually eliminate various organic contaminants. They can also remove:
  • Fluoride
  • Minerals
  • Some arsenic
  • Select microorganisms

4. KDF Filters

• Removes:
  • Chlorine
  • Hydrogen sulfide
  • Mercury
  • Lead
• Manufacturers 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.

5. 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.

6. Water Softeners

• Remove minerals, including:
  • Calcium
  • Magnesium
  • Barium
  • Lead (less than 5 PPM)
• Effective, but increasingly unwelcome in ecologically sensitive areas because the briny wastewater they produce is bad for the environment. They also reduce no chemicals or pathogens.

7. Salt-based softeners (Water Conditioners)

• Changes the chemical composition of calcium and magnesium, preventing limescale formation. They are not as effective as traditional softeners but are cost-effective, produce no wastewater, and do not remove beneficial minerals. Water conditioners are suitable for various settings

Dealing with Iron

Excessive iron in well water can lead to stubborn orange stains, pipe blockages, and an unpleasant taste.

To combat both ferric and ferrous iron, consider an iron filtration system equipped with an inline sediment filter.

For elevated iron levels (over 5 ppm), consider investing in a specialized softener with oxidation technology. This process converts ferrous iron to ferric iron and captures it in a dedicated tank.

Addressing Coliform Bacteria

Filtering coliform bacteria from well water is essential, as their presence can indicate the potential for harmful fecal bacteria. While RO and carbon filters can address coliforms, they may not fully safeguard against microorganisms like E. coli.

To ensure complete protection — we’d consider using chlorine or UV light treatments. While a home chlorinator is an effective but costly option that requires maintenance, a simpler and more affordable alternative is a UV filter.

Removing Arsenic

Arsenic, a naturally occurring chemical element, can contaminate underground water sources in certain regions. While standard water filters and softeners can remove arsenic, they may not always reduce it to safe levels. In contrast, reverse osmosis (RO) systems typically reduce arsenic levels to less than 90%.

For individuals residing in areas with a heightened risk of arsenic contamination, the most effective approach is to install a salt-based softener or an RO system equipped with an active alumina cartridge for maximum arsenic reduction.

Installation Expenses

When it comes to installing a water filtration system for your well, there are various factors to consider, including labor and average costs:

• Complete Filtration System: Installation typically takes 4 to 8 hours and costs between $500 and $1200+.
• Reverse Osmosis System: Expect an installation duration of 4 to 8 hours with costs ranging from $500 to $1200+.
• UV Disinfection System: Installation usually takes 4 hours or less, with an average cost between $350 and $600.
• Softener or Conditioner: Installation can often be completed in 4 hours or less and may cost between $500 and $1200+.

These costs can vary depending on your specific location, the complexity of the installation, and the system type you choose.

Ownership Costs

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?

Simplified Upkeep

The ideal water filter for well water should offer hassle-free maintenance that doesn’t break the bank.

Typically, most systems necessitate filter replacement every 6 to 12 months. However, making a slightly larger upfront investment may help minimize or even eliminate these annual expenses. Take your time to evaluate your choices and select the one that aligns with your budget and requirements.

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+

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.

Understanding Warranties

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.

Pros & Cons

Pros:

• Filtration systems offer clean, safe drinking water for homes and businesses.
• They are cost-effective and low-maintenance compared to other filtration methods.
• These systems employ filters designed to eliminate contaminants like bacteria, viruses, sediment, and chemicals before water enters properties.
• They reduce health risks tied to contaminated well water.

Cons:

• Installing and maintaining well water filtration systems can be costly due to their complexity and specialized components, such as pumps and tanks.
• Neglecting maintenance can lead to reduced performance or system failure over time.
• Some contaminants may persist, requiring regular monitoring and testing.

Installation (Step By Step)

Here’s a straightforward guide on installing a whole home water filter system. You can often find helpful installation guides on YouTube or the manufacturer’s website.

1. Start by turning off the main water supply to your home. This ensures no water enters your house during installation.
2. Choose a suitable location for your filter, preferably near existing plumbing fixtures or in a basement utility room. Ensure there’s enough space for easy access and future maintenance.
3. Install shut-off valves before and after the filter. This allows you to turn off water when needed without disrupting your entire home’s water supply.
4. Connect a flexible hose from the outlet side of your well pump to an inlet port on the whole house filter system using appropriate fittings, such as compression fittings.
5. Attach another flexible hose from an outlet port on your filter system back into your home’s plumbing system using the right fittings.
6. Slowly turn on the main water supply valve to purge any air from the hoses connected to your new whole house filter system.
7. Check for leaks around the fittings and tighten them if necessary.
8. Turn on the shut-off valves before and after your filter system to allow water to flow through it.
9. Test water pressure from faucets and showerheads to ensure it’s within acceptable levels. If needed, adjust your well pump settings to achieve adequate pressure throughout your home.
