Best Water Filter for Well Water:
1. Springwell WS1 Whole House Well Water Filtration System
The WS1 is Springwell’s flagship well water filtration system and one of the most popular and coveted water filters on the market. It’s the ideal solution to orange and reddish tint caused by iron, or rotten egg smell due to excess sulfur.
The Springwell WS1 is also one of the most convenient whole-house filters we’ve come across and it more than lives up to its reputation as a “set and forget” system. Once installed, it can be operated remotely via the Springwell Water Smart app, which gives you a great deal of control over its valve settings and insights into your water usage. This is great if you’re looking to reduce the amount of water you use at home and bring down your water bills.
Let’s take a look at the key features that have earned this filter the top spot on our list.
AIO Technology
The Springwell WS1 uses Air Injection Oxidation (AIO) technology to up to 8 PPM of hydrogen sulfide, 7 PPM of Iron, and 1 PPM of manganese. The water flows through the pocket of compressed air on the top of the tank to oxidize these contaminants. When the water flows into the media bed, oxidized contaminants stick to the media, leaving you with clear, odorless water.
The media bed is then washed and drained automatically to get rid of oxidized contaminants.
Green Sand Filtration Media
The WS1’s green sand filtration media targets and removes harmful contaminants like:
- Chloramine
- Chlorine
- PFOS
- PFOA
- Iron
- Sulfur
- Manganese
After the water has passed through the air pocket created by the AIO tech, the green sand filter traps the oxidized contaminants to prevent them from entering your home’s water supply. The end result is clean and safe water throughout your entire household.
Low Maintenance and Digital Controls
You’ll be pleased to know the system itself does not require any maintenance. You just have to set your preferred settings and let it run. There is an option for daily backwashing so you can enjoy clean water at all times.
Thanks to Bluetooth technology, you can control the system settings through your phone or tablet. This allows you to monitor and adjust backwash cycles, media regeneration, and valve settings easily. You can also see your water usage.
High Flow Rate and Excellent Warranty
With a 12 GPM flow rate, the Springwell WS1 can deliver constant water pressure for large houses. The unit is built with NFS-certified components and comes with a lifetime warranty and a six-month grace period.
If you feel that the system isn’t up to par with your needs, you can return the unit during those six months (provided it isn’t damaged or modified) for a refund. However, Springwell charges a 25% restocking fee, so you won’t get a full refund. Beware that shipping charges aren’t covered by the warranty. You’ll also have to pay for return shipping.
Just bear in mind that the installation isn’t very easy, and you may have to hire a professional if you aren’t experienced with DIY plumbing projects.
Pros:
- We really like the fact you can set the system to automatically backwash on a daily or weekly basis. This flushes the media and ensures the system is running with optimal efficiency.
- The WS1 is designed to require little to no maintenance and the filter media’s lifespan is over 10 years. This means you can simply let it do its work without the need for frequent repairs and replacements.
- Another thing we love about this filter is the fact it doesn’t cause any drops in water pressure. Once it’s installed, your faucets and shower heads will maintain the same pressure levels as they did previously.
- If your water pressure is anywhere between 25 to 80 psi, the WS1 can deliver 12 GPM (gallons per minute).
Cons:
- Installing the WS1 yourself can be quite difficult as some experience with plumbing and household tools is required. On the plus side, SpringWell includes a detailed instruction manual, which we found really helpful.
- The WS1 is one of the most expensive systems on the market; upgrades for it, like the UV water purification system, can cost more than $1,000
- Iron removal up to 7 PPM
- Hydrogen Sulfide removal up to 8 PPM
- Manganese removal up to 1 PPM
- Can deliver 12 GPM
- Springwell AIO System that used oxidation technology
- Daily backwash setting
- Bluetooth control
2. Aquasana Rhino Well Water Filter System With UV Filter
The Aquasana Rhino is another excellent well water treatment system that comes with a UV Filter that eliminates 99.99% of viruses and bacteria. Thanks to a combination of KDF, Activated Carbon, and UV light filters, it removes and reduces many contaminants, including but not limited to chlorine, herbicides, pesticides, lead, and sediment.
This reduces the health risks associated with these contaminants and provides you with clean water for bathing, cooking, cleaning, and all other uses.
As well as removing harmful bacteria, the Aquasana Rhino also reduces the levels of hydrogen sulfide, chlorine, and iron in your well water. This prevents rust staining and removes unpleasant, eggy odors. The filter system’s key features include:
Three-Stage Filtration and Dual Tank System
Once you install the system, water flows through the pre-filter, the dual tank, and the post-filter before it reaches the last step of filtration: the UV light.
Thanks to the dual tank system, the water spends a long time flowing through the filters, allowing the filter media to grab more contaminants than single tank units. Most contaminants are eliminated by Carbon and KDF filters, and the UV light takes care of microorganisms, viruses, and bacteria before the water is distributed to the house.
The dual tank design ensures maximum contaminant removal and makes the unit a lot less prone to clogging. Bacteriostatic media prohibits algae and bacteria growth in the system.
The Rhino delivers up to 14.7 GPM flow rate with constant water pressure.
Cost-Effectiveness
The Rhino is the cheapest filtration system we picked. It offers a great cost/quality ratio, even if you have to change the UV lamp annually. It comes with a five-year warranty and a 90-day money-back guarantee. The company doesn’t pay for return shipping costs.
However, the Rhino requires frequent filter replacements. You’ll need to replace the pre-filters every two months, the post-filters every six months, the UV lamp annually, and the tank every 5 years. While pre and post-filters aren’t very expensive, the UV lamp replacement can set you back around $100.
You should also bear in mind that if you choose to install the system on your own, you will need to order a Pro-Grade Install Kit ($100). Yet, the Aquasana Rhino can be hard to install by yourself if you don’t have experience in DIY plumbing projects. In that case, you may want to consider hiring a professional installer.
NSF (National Sanitation Foundation) Certification
Another key feature of this system is the fact it’s certified to NSF/ANSI standard 42. Essentially, this indicates that the media and overall system are certified for the effective reduction of contaminants.
To gain certification, the system is rigorously tested to determine how well it improves the taste, odor, and appearance of well water.
Pros:
- The three-stage filtration system promises “better than bottled water” quality for the whole household
- The use of UV light sanitation eliminates the bacteria and viruses that are commonly found in well water
- It’s a more affordable option than the SpringWell WS1
- It can deliver a flow rate of 14.7 GPM, which means it’s ideal for homes with 1-4 bathrooms. Plus, you won’t experience a drop in your water pressure once the system has been installed.
Cons:
- If you enlist the help of a plumber, the installation process is quick and easy. However, as with the SpringWell WS1, DIY installation can be quite tricky. If you choose to install it yourself, you’ll need to order the Pro-Grade Install Kit which can cost up to $195.
- The Aquasana Rhino doesn’t include backwashing which means the filters must be regularly replaced
- A dual tank system
- Pre-filter and post-filters
- A well-designed shut-off valve

Our Review Criteria for Well Filtration Systems
We evaluated home well water filter systems based on the following criteria:
Contaminants Removed
The most important parameter is the filtration system’s ability to filter out different types of contaminants. We ranked how well the systems eliminate different contaminants, such as heavy metals (copper, cadmium, arsenic, lead, and chromium), micro-organisms, viruses, bacteria, organic chemicals, and substances such as pharmaceuticals, pesticides, paint, and disinfectants.
The winner in this category is, hands down, the Aquasana Rhino Water Filtration System. This unit is a jack of all trades, but the most impressive fact is that it manages to do everything that it’s supposed to at the highest possible level.
The Springwell WS1 came second, and it’s the best for removing iron, hydrogen sulfide, and manganese from water. While it’s not as efficient as SoftPro when it comes to removing high levels of iron, it’s one of the most well-reviewed and appreciated filters in the market.
Springwell LCR is the best for removing lead, PFAS, and PFOA (also known as forever plastics) in well water.
Although SoftPro Ironmaster came fourth, don’t be fooled by its humble rank. This unit can remove a staggering amount of iron (up to 30 ppm), as well as hydrogen sulfide and manganese, from water without breaking a sweat.
Springwell STR removes tannins and hard minerals. It’s basically a water softener.
Well Filtration Systems (Best to Worst) | Well water Contaminants Removed |
Aquasana Rhino | 99.99% of bacteria and viruses. 97% of chlorine. Reduces harmful contaminants like lead, mercury, herbicides, pesticides, rust, silt, sediment, water soluble metals and industrial solvents, VOCs, and more. |
Springwell WS1 | 7 PPM of Iron, up to 8 PPM of Hydrogen Sulfide, and 1 PPM of Manganese |
Springwell LCR | Lead, PFAS, PFOA and treats cysts, chlorine, chloramine, and other harmful contaminants |
SoftPro Iron Master | 30 PPM of Iron, 5 PPM of Hydrogen Sulfide, and 7 PPM of Manganese |
Springwell STR | Tannins (dissolved organic materials in the water) and hard minerals |
Flow Rate
Water flow rate is the amount of water the system can handle at any given moment of time. It’s measured in gallons per minute (GPM).
While most houses use 2 or 3 GPM, the norm for whole-house filtration systems is 7 GPM. This is a solid number and anything below that will likely decrease the water pressure. If you have multiple bathrooms and kitchens, you’ll appreciate a system with a high flow rate.
The Aquasana Rhino is capable of delivering constant water pressure levels of nearly 15 GPM.
That said, all our picks feature a flow rate higher than 7 GPM, which can comfortably support up to 4 bathrooms.
Well Filtration Systems (Best to Worst) | Flow Rate |
Aquasana Rhino | 14.7 GPM |
Springwell WS1 | 12 GPM |
SoftPro Iron Master | 12 GPM |
Springwell LCR | 8 GPM |
Springwell STR | 8 GPM |
Filtration Technology
We can’t exactly rank filtration technologies from best to worst since they eliminate different contaminants.
If you need to remove hard minerals from the water, a simple ion-exchange water softener device might be sufficient. But if you have a more serious issue, such as viruses and bacteria in your water, you’ll need different technology, like a UV filter.
Aquasana Rhino uses three different filtration methods, including a carbon filter, a KDF media filter, and a UV lamp.
Thanks to ionic-exchange technology and 0.5-micron filters, Springwell LCR removes lead and forever plastics from your well water.
Springwell WS1 and IronMaster both utilize air injection technology to remove iron and manganese from the water.
Finally, Springwell STR is an ion-exchange device, or more simply, a salt-based softener that removes hard minerals from water.
We’ll explain each filtration technology in more detail in the next section. For now, here is a handy list of each product and the filtration tech they use.
Well Filtration Systems | Filtration Technology |
Aquasana Rhino | Carbon + KDF + UV Filtering |
Springwell LCR | 0.5 micron filter +Ionic Exchange |
SoftPro Iron Master | Air Injection Oxidation (AIO) |
Springwell WS1 | Air Injection Oxidation (AIO) |
Springwell STR | Ion Exchange |
Ease of Installation
We also ranked each system according to the ease of installation.
Some of these systems are relatively easy to put together if you’re used to DIY projects, but a few are more complex, and you might need professional help to set up.
If you don’t have experience with plumbing projects, it might be a good idea to hire a professional.
Beware that some professionals may refuse to assemble the system to avoid voiding your warranty. You can ask your local plumbing store if they sell the unit you wish to purchase. If yes, they’ll be able to set it up for you quickly and efficiently.
Each unit on our list comes with a set of instructions to help you assemble the filter. You’ll also find helpful YouTube videos for each product online.
While each unit comes with all the essential parts, you’ll still have to purchase connectors that fit your water pipes.

Our number one pick is Springwell WS1. It’s a set-and-go system that requires no maintenance. You can monitor it through Bluetooth via your phone.
Softpro Iron Master requires very little maintenance. The katalox media lasts 5 to 10 years (or 3 to 5 years in extreme circumstances). You might have to replace inexpensive parts, including the piston or seals, due to sediment infestation. The system doesn’t require regular maintenance.
Springwell LCR is similarly easy to use. You only need to change the pre-filter every 100,000 gallons or after 1 year of use.
Springwell STR features a Bluetooth mode that allows you to monitor the salt levels in the brine tank. Since it’s a salt-based softener, you need to add salt to the system regularly.
Finally, we have Aquasana Rhino, which needs more maintenance compared to other systems. Its pre-filters should be replaced every two months, post-filters every six months, the UV lamp annually, and the tank every 5 years.
Well Filtration Systems | Maintenance Requirements |
Springwell WS1 | Minimal |
SoftPro Iron Master | Minimal |
Springwell LCR | Low |
Springwell STR | Regular |
Aquasana Rhino | Advanced |

The Most Common Water Filtration Technologies
Naturally, we all want the best possible filter that we can afford, but which technology is the best? Well, the answer isn’t cut and dried. The best filtration technology is the one that best serves your needs
Let’s look at the most common water filtration technologies and see how they compare:
UV Filtering
UV water filtering systems make use of special UV lamps that emit UV light at a certain wavelength that disrupts the DNA/RNA of microorganisms such as bacteria, viruses, or cysts.
UV light waves use a Germicidal Spectrum or Frequency, which is 254 nanometers (nm). As the water passes through the UV filter, bacteria and viruses are exposed to this frequency and destroyed.
UV water treatment units have risen in popularity because they are a surefire way of removing 99.99% of all harmful microorganisms. However, UV filtering only works when paired with pre-treatment solutions. Otherwise, viruses and bacteria can hide behind sediment and other particles. The water has to be completely clear for the system to work. UV filters are often used as the last step in water treatment systems.
KDF Filters
KDF or Kinetic Degradation Fluxion filters are staples in water pre-treatment in both residential and industrial water filtration.
The filters feature zinc-copper alloys and produce an electrochemical reaction known as oxidation-reduction (redox). The process can remove or reduce lead, chlorine, mercury, iron, magnesium, hydrogen sulfide, chromium, calcium carbonate, fungi, algae, and bacteria from water.
The most common KDF filter on the market is the KDF 55, which is catered to fine granule mediums and reduces substances such as chlorine and soluble heavy metals.
Air Injection
Air injection filtration is a great water treatment approach that removes iron, sulfur, and manganese. As water flows through a tank equipped with an air chamber, the iron in the water oxidizes. When it reaches the media bed, the oxidized iron is trapped in the media.
The same method is used when removing substances such as sulfur and manganese.
Granular Activated Carbon Filters
Granulated activated carbon filters (GAC) are one of the most utilized filters in pitcher filters and dispensers. You will find them in stock in your local supermarket and local retail shops.
Granulated activated carbon can adsorb certain chemicals in the water. It’s effective for removing VOCs, organic chemicals, chlorine, and hydrogen sulfide (sulfur or rotten eggs smell).
Carbon Block Filters
Carbon block filters are similar to GAC filters, but they’re more effective in filtering contaminants due to their compact structures (1 micron or less in size).
When water passes through the carbon block, carbon eliminates chemical contaminants. Sediment and other physical contaminants can’t pass through the block due to the small pore size.
Carbon block filters with 0.5 microns are well equipped to remove most contaminants found in well water, including chlorine, herbicides, pesticides, PFOS, pharmaceuticals, VOCs, and certain bacteria. Top-quality carbon filters can remove PFAS, mercury, asbestos, and radon from water.
You can expect a carbon block filter to remove anywhere from 50-60 contaminants from your water.
Reverse Osmosis
The products we choose don’t use Reverse Osmosis (RO) technology, but some of them offer an RO filter addition you can purchase.
RO systems have 0.0001-micron size semi-permeable pores that remove dissolved solids, as well as bacteria and viruses, from the water.
RO systems can remove lead, sodium, chromium, copper, and chloride from water. They can reduce hard minerals like magnesium, calcium, and potassium as well as nitrate, arsenic, sulfate, fluoride, phosphorus, and radium.
Basic RO systems will successfully remove about 14 different contaminants on their own, but they really shine when they are combined with activated carbon filters. Together, they can remove about 70 contaminants—which is the pinnacle of water filtration at the moment. We also have a reverse osmosis system for well water article you can check out.
Frequently Asked Questions
Out of all the products we picked, the Aquasana Rhino removes and reduces the most contaminants, thanks to its triple carbon + KDF + UV light filters.
That said, you can also use a whole house RO system paired with a carbon block filter to eliminate the highest number of contaminants from water. Beware that RO systems have multiple disadvantages, though. You may not be able to use them in some states due to environmental regulations since they produce a lot of wastewater.
They also remove healthy minerals from the water, and you have to install a remineralizing filter to make up for the loss.
A new well filtration system can cost you $1,300- $2,500.
However, these are mostly whole-house systems that address specific problems.
You can also purchase affordable under-the-sink systems from $150 to $1,200.
Experience with DIY plumbing projects as well as a dedicated toolkit is very helpful when you’re installing a well filter. Each product we recommend in this article comes with instructions, and you can find multiple videos online to see how the installation works.
While the installation package for these systems usually includes all the important parts, in most cases, you’ll need to buy connectors and fittings that are the right size for your pipes. Other than that, you might require a wrench, some adhesive, tape, maybe a pipe cutter, a ladder, a screwdriver, and some drills.
Springwell (we recommend three different products from the company!), Aquasana, and Quality Water Treatment are all great brands. Other popular brands include 3M, GE Appliances, and Whirlpool.
