Buying Guide: How to Choose the Carbon Well Water Filter That’s Best for You
The following are key features worth considering when shopping for a carbon filter for well water. They will help you choose the right on for your needs and budget.
Finding the Right Carbon Filter for Your Specific Well Water Quality
The first step before purchasing any type of filter system is having your well water tested. Testing will give you an accurate picture of the contaminants contained in the water without having to resort to guesswork.
When it comes to well water there are two types of testing you can perform. The best option is to have your water professionally tested by a testing lab. This involves sending in a water sample and will give you an accurate reading of both of the contaminants contained in your well and their quantities.
Professional testing will cost a couple hundred dollars though, so if you’re trying to save money you can also use a home testing kit. This costs less, but won’t be as accurate and you won’t be able to test for the same amount of contaminants as with professional testing.
Once you’ve identified the contaminants in your well water, you’ll be able to target your filter purchase to eliminate them. There are different types of carbon filters, including both regular activated carbon and catalytic, each of which will eliminate different contaminants.
NSF Standards
Looking for NSF standards is the best way to make sure the water filter you’re buying actually does remove all the different contaminants it’s promised to.
When looking at carbon filters for well water, be on the lookout for the following NSF certifications:
NSF Standard 42(Aesthetic Effects): This standard covers the elimination of so-called ‘aesthetic effects’ from drinking water. This includes chlorine taste and odor as well as particles.
NSF Standard 53(Health Effects): This standard covers the removal of microbial contaminants with known health effects such as cryptosporidium and giardia as well as non-microbial contaminants like lead and VOCs.
NSF Standard 401 (Emerging Compounds): This standard pertains to the removal of emerging compounds like pesticides, herbicides, detergents, retardants, and chemicals from industrial runoff.
NSF Standard P473 (PFOA/PFOS): This is the standard for the reduction of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) – also known as forever chemicals which are highly toxic.
Be aware that not all systems will feature all of the above certifications. The type of filtration offered differs from model to model, so keep this in mind when looking at NSF certifications.
Whole House vs Point of Use
This refers to the two primary types of water filters – whole house (also called point of entry) and point of use systems.
Whole house water filters are installed where your home’s main water line enters the home. They’ll filter all of the water entering your house so you’ll have clean filtered water coming out of every faucet and fixture.
Point-of-use systems – like the name suggests – connect to a particular faucet or fixture and only filter water coming out of that fixture. There are numerous point-of-use system types – including under sink, countertop, and even filter pitchers and gravity filters, so you have plenty of options when it comes to design.
The Type of Carbon Used
There are two primary types of carbon used in well water filtration: Regular activated carbon and catalytic carbon.
Regular activated carbon is primarily used to remove chlorine taste and odor and is less effective than catalytic carbon. It will also remove some pesticides and herbicides, as well as certain VOCs and other organic chemicals.
Catalytic carbon is carbon that has gone through high temperature gas processing to modify its surface. It will remove the same contaminants as activated carbon, but will also remove chloramine, and hydrogen sulfide. Chloramine is less of a concern when it comes to well water, but hydrogen sulfide is very common in well water systems and creates a foul rotten egg odor that makes water unpleasant to drink.
Filter Life
Filter life refers to the filter’s lifespan before cartridge or tank replacement is necessary. This can be as little as 2 or 3 months or as much as 6+ years.
Tank-based systems last significantly longer than cartridge-based systems, although cartridge systems are less expensive upfront and tend to be easy to maintain. Cartridge costs can add up significantly over time as you’ll need to replace the filter cartridges one or more times per year.
Water Flow
Water flow is typically measured as flow rate. This refers to a system’s total capacity to filter water at one time.
Flow rates differ significantly depending if the system is a point-of-use or a whole house water filter. Whole house systems require significantly higher flow rates, as they must be able to filter enough water to run multiple outlets and appliances at once.
For whole house water filters, a system with an 8 to 10 gallon per minute flow rate should be enough for smaller homes with 1 to 3 bathrooms. Larger homes with 4 or more bathrooms will require a 12 to 15 gpm flow rate to avoid low pressure issues.
Point of use systems flow rates will differ significantly based on their design and function. It’s best to compare point of use systems to others of the same type to get a good comparison.
Installation and Maintenance
Whole house carbon water filters for well water will be significantly more complex to install and maintain than point-of-use systems, but that doesn’t mean you can’t install them yourself with a little DIY and plumbing skill.
POU systems are typically very easy to install, with under sink systems being the most difficult to set up, but even these can typically be installed in less than an hour with a few basic tools.
As far as maintenance goes, most carbon filters only require periodic filter cartridge replacement. Tank based systems may not even require any regular maintenance at all.
Space Requirements
Whole house carbon water filters for well water tend to take up significantly more space than their point-of-use counterparts. If you have limited space to install a system, you might need to consider a POU unit anyway.
Cost
While carbon filters for well water tend to be cheaper than other filter types, whole house systems, and systems with additional filtration stages can add up quickly.
As mentioned previously, tank-based systems tend to cost more than cartridge-based systems up front, although filter replacement costs will increase the cost of cartridge-based filters over time. Tank-based water filters don’t require regular cartridge replacements (other than perhaps a single sediment filter) so they tend to have much lower long-term maintenance costs.
Trial Period and Product Warranties
Whenever you’re considering shelling out a large sum of money on a water filter system, a solid warranty will provide significant peace of mind. Likewise, a money-back satisfaction guarantee gives you the ability to return the product for a full refund no questions asked if you run into any issues.
More on Carbon Filters for Well Water
Further Reading:
What Is a Carbon Filter for Well Water and How Does It Work?
While carbon filtration alone won’t remove some of the more common contaminants found in well water like iron, manganese, or microbes, it will remove pesticides, herbicides, VOCs, some lead and other metals, and in the case of catalytic carbon filters hydrogen sulfide.
Additionally, many wells require occasional shock chlorination to keep microbial contaminants in check. Carbon filters will remove any residual chlorine from your well water plus disinfection byproducts, and it will enhance the water’s taste and odor.
The Different Types of Activated Carbon Used in Water Filtration
We briefly touched on the main types of carbon filtration above, but there is a little more to it than that.
Granular Activated Carbon
Granular activated carbon refers to a carbon filter comprised of small ground-up carbon pellets. These pellets allow for a high flow rate but as the contact time with the water is low, they’re less effective than carbon block filters.
For houses or applications that require a high flow rate, it’s sometimes necessary to sacrifice some filtration effectiveness for increased flow rates.
Carbon Blocks
Carbon block filters are filters made of a single solid carbon block. The block is formed from crushed-up activated carbon powder and bound together with a food-grade binder.
This filter type is significantly more effective at removing contaminants than granular activated carbon but will slow down flow rates noticeably.
Catalytic Carbon
Catalytic carbon is an enhanced form of activated carbon that has undergone a high temperature process to enhance its adsorption properties. Catalytic carbon can either be in granular or block form, although the granular form is more popular.
What Are the Benefits of Installing a Carbon Filter for Well Water?
Cost
One of the biggest benefits of carbon filter systems for well water is their relatively low cost. Carbon filters – at least basic carbon filters – are very cheap while still being effective at contaminant removal.
This is especially true for POU systems that can be purchased for just a couple hundred dollars or less.
Water Taste and Appearance
Carbon filters are known for their ability to enhance the taste, odor, and appearance of well water and any water in general.
Healthier Water
Removing chlorine, disinfection byproducts, VOCs, pesticides, herbicides, and other chemicals not only enhances the well water’s taste but will also make it healthier for you and your family to drink.
Whole house chlorine removal will also lead to healthier-looking hair and skin when you shower or bathe.
Ease of Use
Most of the above systems require little maintenance and are easy to use. Even the whole house filters don’t require a drain connection.
Low Maintenance
Most carbon well water filters require very little maintenance, with most only requiring occasional filter cartridge replacements. Pitcher and gravity systems tend to require filter changes every few months, while under sink/whole house systems only require replacement every year or so.
Disadvantages of Carbon Well Water Filter Systems
Contaminant Removal
Perhaps the biggest drawback to using a carbon filter system to filter well water is that carbon alone won’t remove all of the contaminants commonly found in well water – think iron and manganese.
Now, most of the systems above use other filtration methods to get around this, but be aware that carbon alone may not be enough to filter your well water.
May Need Additional Filtration
If your well water is especially contaminated, then you may need to install additional pre-filtration. This is often the case for well water high in iron or manganese, both of which are difficult to remove and can be hard on filter systems.
Frequently Asked Questions (FAQ)
Should you use a carbon filter on well water?
Yes, using a carbon filter for well water is perfectly fine. Just know that it won’t remove some of the common well water contaminants such as iron and manganese.
How often should you change a carbon filter when used on well water?
It depends on the exact filtration setup, but for a point-of-use filter you’re probably looking at one or two filter replacements per year.
What are the advantages of activated carbon water filters?
Activated carbon filters are affordable and easy to use. Plus, they improve water aesthetics and some potentially harmful water pollutants such as pesticides.
What does a carbon filter remove from well water?
A carbon filter can remove the following contaminants from well water: Chlorine, disinfection byproducts, pesticides, VOCs, industrial solvents, and many other kinds of organic chemicals. It can also remove lead and few other heavy metals. Catalytic carbon also removes hydrogen sulfide.
Which is the best type of carbon for well water?
We recommend catalytic carbon due to its high effectiveness against sulfur. A carbon block filter also helps to remove sediments better than granular carbon. However, watch out for clogging!
How We Chose and Tested the Best Carbon Well Water Filters (Why Trust Us)
You won’t believe the wild ride we embarked on to conquer the realm of carbon filters for well water. Get ready for a review process that involved relentless research, daring experimentation, and intense scrutiny:
First, we had to create a list of criteria to serve as our ultimate benchmark. We uncovered 22 essential attributes that we deemed crucial.
Next, we had to find as many carbon well water filters as possible, so we went on the internet and gathered a whopping 35 different systems that would undergo our rigorous review process.
Round one involved diving into a treasure trove of information from manuals, descriptions, warranty conditions, lab reports, NSF certifications, and other data. We even reached out to the companies themselves (like SpringWell, USWS, and Clearly Filtered) to uncover the mysteries of their support level. The journey was arduous, but it narrowed down our contenders to no more than 15.
But we didn’t stop there. Oh no, we sought the wisdom of real users and third-party sources, seeking their feedback and ratings. And with that, only 7 worthy products remained.
It was time to put some of them to the ultimate test. We ordered + hooked them up to our water supply, taking note of installation difficulty, maintenance needs, filtered water aesthetics, etc. Each filter was put through its paces for at least two weeks. Meanwhile, we got our hands on water test kits from Tap Score measuring contamination reduction (chlorine, lead, fluoride, manganese, and more).
To arm you with the knowledge you need to find the perfect carbon filter for well water, we condensed everything we discovered into this user-friendly buying guide, which is 100% independent, unbiased, and fact-checked (most importantly, Buddhini Dolapihilla, MBSS played a pivotal role in verifying contamination reduction claims, which involved checking NSF certifications online and carefully examining lab reports and other test data).
