Buyer’s Guide – How to Buy a Well Water Filtration System

A whole house well filtration system has many benefits, IF you choose one that’s up to standards. But what does that even mean? Here’s our buyer’s guide with everything you need to know about how to buy the best water filtration system for well water.

Whole House Filter Types

Most whole house filters use activated carbon to remove water disinfectants and their byproducts, (in-)organic chemicals such as pesticides, a few heavy metals, and, at least as important, unpleasant taste and odor. Usually, the carbon is in granular form. Carbon blocks are rarer.

Often, those whole house filters also apply pre-filtration to get rid of sediments that would otherwise clog the system. More sophisticated models might even feature additional filter media, for example KDF (kinetic degradation fluxion), a copper-zinc mixture, to improve overall filtration effectiveness and prevent microorganisms from accumulating.

Whole house water filtration systems specifically designed for the treatment of well water, however, are different. They often focus on filtering the different forms of iron as well as manganese and hydrogen sulfide (rotten egg smell[2]), which are common contaminants in well water. Filtration methods used include aeration, chlorine injection, and ozonation for pre-oxidation often followed by mechanical filtration.

We also find well filter systems that will only remove suspended solids – think sediments and inorganic metals – to enhance water quality. One example for a 5-micron sediment filter is the Fleck 5600 listed above. Its primary filtration media is ChemSorb.

Then we have well water filters that also apply sterilization which is key if you’re dealing with waterborne pathogens. Most prominent are UV filters that inactivate up to 99.99% bacteria like E Coli, viruses, and other microorganisms.

Filtration Stages

Another way to group whole house filter systems is whether they’re cartridge-based units or whether they use one or more large media tanks. The latter is more expensive upfront but doesn’t require much of your attention once set up. Well water filters that work with cartridges need regular maintenance. Above that, the cost for continuously buying replacement filters can really add up over time.

Well Water Quality & Treatment

Which of the above whole house filter types is best suited for your well depends on its water quality.

Thus, before buying a water filter make sure to have your well water thoroughly tested so that you can answer the following questions:

  1. Which harmful contaminants are present in your private well and at what levels?
  2. What’s your water’s pH range?
  3. What is the hardness level and TDS (total dissolved solids) concentration

Only by testing for these water parameters can you buy a filter system that’s capable of effectively removing any undesirable contaminants.

How to test? Theoretically speaking, you could do this yourself using one of the many water test kits available at your local hardware store, but results may lack accuracy and you can only test for a narrow range of pollutants. What we recommend instead is hiring a professional lab, Tap Score for example. This will give you a more complete picture of the situation.

Micron Rating

Sediment filters remove suspended solids from water. A low micron rating means even the smallest particles will get caught.

1 micron = 1/1000 of a millimeter

However, a lower micron rating may also reduce output water pressure. And if you go too small all you get may be a fine trickle or water flow will stop entirely. In other words, try to find a good balance between filtration effectiveness and usability.

By the way, common micron ratings are 50, 25, 10, 5, and 1. Submicron ratings are rare with whole house water filter systems. From our list, only the Aquasana EQ-Well-UV has a submicron rating.

Flow Rate & Water Usage

trickling faucet

It is estimated that the average domestic water use per capita and day is between 50 and 100 gallons of water. This can be broken down into:

  • Showering: Back in the day, high-flow shower heads used up to 7 gallons of water per minute. Today, low-flow models use no more than 1.5 gallons per minute.
  • Faucets: The current federal standard for kitchen faucets is 2.2 gpm. Bathroom faucets use no more than 0.5 gpm with a high-efficient aerator.
  • Toilets: Old toilets used up to 7 gallons per flush, while newer models use as little as 1.3 gallons.
  • Washing dishes: The most efficient dishwashers use no more than 4 gallons per load. In the past, they used to consume 15 gallons.
  • Washing machine: Did you know that front loaders save a lot of water compared to top loaders? 15 gallons per load versus 40.[3]

If you do the math, you’ll find that your peak water usage might be higher than you had expected – when your kids are taking a shower, your spouse is washing vegetables in the kitchen sink, the dishwasher is running, and you’re putting a new load into the washer.

Why is this important? Because your potential new whole house water filter must be capable of meeting your water demand at times of peak consumption. Otherwise, you might see a water pressure drop or unfiltered water bleeding through.

A good baseline is at least 8 to 10 gallons per minute for the average-size household (family of 4). Larger homes may need 15 gallons per minute and more.

Filter Life

Media beds last for at least several years; filter cartridges not so long which means higher maintenance needs.

Available Space

Whole house filter systems aren’t exactly small, so double-check that you have enough room near the main water supply line to accommodate a unit.

Budget

If you’re not a do-it-yourself type of guy, don’t forget to take into account the cost for professional installation and maintenance before buying a home water filter.

Especially long-term expenses can be much higher than the initial cost of purchase with cartridge-based filter systems.

What Is a Whole House Water Filter for Well Water

best whole house water filters for well water thumbnail large

If you’re on well water a whole house filtration system is a must. It connects to the main water line to treat all water at the point of entry and before it gets distributed via the various lines in your home.

Why is using a whole house water filtration system important? Because it protects your health and it extends the life of your entire plumbing system and home appliances. Additionally, water taste and smell will be much better, and your clothes won’t stain and keep their color.

Once installed, a whole house water filter is easy to maintain. In fact, many systems don’t require any servicing for years. With cartridge-style filters need replacement every 6 to 12 months.

Why Do I Need a Well Water Filter System?

Do you even need a whole house water filter when you’re on your own private well?

A well water source can expose you to a variety of harmful contaminants like arsenic. While municipal water systems use water treatment and monitoring to protect consumers, private wells do not receive the same services. It’s in the well owners’ own responsibility to filter their water.

Contamination Sources

Contamination sources affecting private wells can be naturally occurring and man-made. For example:

  • Heavy metals can leach into your well water directly from your home’s plumbing or from industrial and commercial sources including mining operations, petroleum refineries, and municipal waste disposal. There also are natural deposits that can contaminate private wells through groundwater movement and surface water seepage. Harmful metals commonly found in well water include arsenic, chromium, and lead. High exposure can result in toxicity, organ damage, and cancer.
  • Microorganisms originate from human sewage and animal waste. They enter wells when being picked up by water run-off from rainfall or snow-melt. Other pollution sources are leaking underground waste storage tanks and septic fields. People that drink polluted water can experience gastrointestinal illnesses and infections.
  • Organic chemicals as found in many household products and widely used in agriculture and industry contaminate private wells through surface water run-off, waste disposal, and spills. People that are exposed may suffer from kidney and liver damage, and impairment of the nervous and reproductive system.[4]

Apart from protecting yourself from being harmed, filtering your well water also protects your plumbing system and home appliances from damage.

How Does a Whole House Water Filtration System for Well Water Work and What Does it Remove?

Installed at the main water supply line, a well water purification system filters all water at the point of entry.

Many systems use surface pre-filters to remove larger particles and thus prevent clogging of the other filter elements.

This is followed by the main filtration process. Depending on the type of system, this might be a large media tank that combines air injection oxidization – other methods for pre-oxidation are chlorine injection and ozonation – with greensand filtration to reduce iron, manganese, and sulfur content. Simply put, well water flows into the filter system. Then, the water passes through the media bed and re-enters your plumbing system all nice and clean.

Another common type of well water filter focuses on removing nothing but high amounts of suspended solids. These filters are also called sediment filters.

Filtration using granular activated carbon makes sense if you found organic chemicals like pesticides in your well water. Carbon also helps with the removal of excess chlorine in case you rely on shock chlorination for disinfection. And it greatly improves water aesthetics in most cases.

KDF media is often added to support contaminant removal and control microbial growth. Bone char and activated alumina can be used to remove naturally occurring fluoride.

UV filtration is the best way to sterilize water killing up to 99.99% viruses and bacteria AND algae.

Where and How to Install a Whole Home Well Water Filter

In well water systems, you should install your whole house water filter after the pressure tank and before any water softening or water condition equipment. This allows the filter system to backwash and at the same time it protects the water softener or conditioner from damage caused by contamination.

Should you try installing a whole house water filter yourself? If you are handy with tools and maybe even have some prior plumbing experience we think you should definitely give it a try. Not having to call a professional handyman will save you hundreds of dollars. And if you use flex tubing and shark bite fittings you won’t even have to do any soldering.

To give you a basic idea of what the installation process looks like, here are some general instructions. Please remember that the individual steps may differ for your specific setup:

  1. Some filter media require priming before use. In case this applies to your filter system, follow the manufacturer instructions. The priming can take up to 48 hours.
  2. Next, close the valve at the main water line. All remaining water needs to be drained. You can do so by opening the nearest outlets.
  3. Cut into the water line. Remove a short section where you install and service your well filter system comfortably.
  4. Some manufacturers recommend installing a shut-off valve on both sides of the filter. A bypass can make a useful addition, too.
  5. Making sure the whole house filter stands on level ground and faces the right direction is key. Then, connect the filter inlet to the incoming water supply and the filter outlet to the outgoing water supply. Plumber’s tape should be applied to all threaded ends for proper sealing – unless instructed otherwise.
  6. Slowly open the main valve with the filter system still in bypass position. Check for leaks.
  7. Open the bypass valve and let water enter the system. Check for leaks and flush out any air and installation debris.
  8. The whole house water filter might require proper flushing before use.

Maintenance: Changing a Whole House Water Filter

Whole house water filtration systems are maintenance-free for the most part. Only filter cartridges need replacement up to a couple of times per year. What’s important is that you replace each filter stage in a timely manner to ensure peak performance (check the product manual for more info).

When it’s time for a filter replacement, you can follow the process as outlined here:

  1. Shut off the water supply to the filter. All remaining water needs to be drained. You can do so by opening the nearest outlets.
  2. A filter housing is best to be opened with a filter wrench or strap.
  3. Remove the old filter cartridge from the housing.
  4. The inside of filter housings may require cleaning or sanitizing.
  5. Check the condition of O-rings. Lubricate or replace if need be.
  6. Insert a new filter cartridge into the filter housing and screw it back on.
  7. Slowly open the water supply. Check for leaks.
  8. The new filters might require proper flushing before use
