Best Sulfur Removal Systems

If you have well water coming into your home that has a high sulfur content (usually in the form of hydrogen sulfide), I wholeheartedly understand why you are so determined to get rid of that sulfur from your tap water.

I remember regularly going to my best friend’s house as a teen to work out and I absolutely dreaded taking a shower afterward.

That’s because of the overwhelming sulfur-related ‘rotten egg smell’ that permeated the entire bathroom once the shower valve was turned on. It even lingered on my skin after my shower was finished. 

That rotten egg smell coming from your drinking water is just one of the drawbacks of having household water with a high hydrogen sulfide content. 

The good news is that sulfur water filter systems have been developed that do an outstanding job of removing sulfur and other contaminants from your incoming tap water.

In this article, I will take an in-depth look at the best sulfur removal systems. 

I will also discuss what to consider when shopping for a hydrogen sulfide treatment device and talk a little more about why it’s a good idea to remove sulfur from your water.

This will enable you to purchase the best sulfur removal system for your water quality needs.

What To Look For When Choosing A Water Filter For Sulfur Lowering

Here are the traits of a sulfur filter system that you should key on when shopping for one of these devices:

Sulfur Treatment Method

This is how a system works to remove hydrogen sulfide and the sulfur-consuming bacteria that contribute to sulfur-related problems in tap water. Most water filter system devices work very straightforward and do not require ultra-sophisticated processes.

Other Contaminants Removed Or Altered By The System

Sulfur water filters may also eliminate or reduce other tap water contaminants too. The more the better and this can be a deciding factor in your purchasing decision. For example, most catalytic carbon filters can remove chlorine and more from water. 

Ease of Installation & Maintenance

You certainly will want to know how easy the sulfur lowering system that you are thinking about purchasing is to set up, operate & clean, and what other types of regular maintenance that it needs.

This includes a device having such features as a remotely programmable control head such as that shown below.

System flow rate

While it’s true that you need to remove problematic sulfur from your incoming water, you don’t want to sacrifice a huge amount of water pressure in your home to accomplish this. 

Make sure that you know the working flow rate of any sulfur filtration system that you are thinking about buying.

Construction & Durability

Chances are that you will be installing your water filter in a garage or basement. These are generally tough working environments for equipment.

That’s why you want your water systems that eliminate sulfur to have a tank that does not dent easily and is made using corrosion-resistant parts.

Warranty

Warranties and guarantees are also a nice little bonus that can impact your sulfur water filter purchasing decision. The better the warranty/guarantee, the more it indicates that a manufacturer has much confidence in their product being able to do what they claim it can.      

Price

Not many of us have unlimited budgets when it comes to installing specialized equipment around our homes. So, the purchase price always has a role to play when it comes to choosing a water filter that removes or reduces sulfur.

Review of Best Sulfur Removal Systems

If you have high sulfur content in your incoming tap water, I don’t think that you can go wrong by purchasing any filtration system on this list to correct that issue.

#1 SpringWell Whole House Well Water Filter System

SpringWell-WS-Whole-House-Water-Filter

This is a nicely designed and highly rated sulfur filter. Its main purpose is to treat incoming well water for problematic sulfur, iron, and manganese.

This sulfur water filter system does a very good job at this and getting rid of the rotten egg smell that goes along with sulfur in water conditions. 

That’s why it is easily our top choice for reducing sulfur content in your home’s water.  

It combines a 4-stage filtration process with advanced air injected oxidation. The SpringWell Whole House Well Water System also has a very constant flow rate and is built tough so it should last you well over 20 years once you have installed it.

Although this water filter’s initial cost is somewhat high, you shouldn’t overlook the fact that it does a great job reducing sulfur in water, is virtually maintenance-free after the initial setup, and has a Bluetooth control head so it can be remotely operated.

It’s designed to last 20+ years and is also backed up by an outstanding satisfaction guarantee and warranty.

Main Features & Benefits

Sulfur Treatment Method: This filtration system uses what is known as oxidation to eliminate the vast majority of sulfur (in the form of hydrogen sulfide) that passes through it.

In Layman’s terms, adding an oxygen particle to the sulfur particles in water enlarges them and makes them easier to filter out.

Activated carbon filters then remove the bigger pieces of sulfur from the system. SpringWell is so confident in this system’s ability to remove hydrogen sulfide down to 8 PPM, they guarantee it.  

Other Contaminants Removed or Reduced: This water treatment device is specifically designed to reduce problematic iron, sulfur, and manganese in well water. In addition to removing all but trace amounts of hydrogen sulfide, it will also provide iron removal up to 7 PPM and manganese removal up to 1 PPM.

An optional bacteria-killing UV light can also be purchased for use with it.

 #3 Matrixx Infusion Iron and Sulfur Removal System

This sulfur treatment filtration system is unique because it uses a combination of chemical injection and filtration system rather than a completely self-contained oxidation tank system. 

This has proven to be a very effective way to eliminate sulfur (hydrogen sulfide) from incoming well water.

It will also remove significant amounts of iron and manganese. Other features include a control head that can be programmed using an app on a smart device, a 15-gallon peroxide tank, and a precision injection panel.

It has a decorative and durable stainless-steel tank, can remove sulfur from water in homes with up to 4 bathrooms, and it offers the convenience of being a maintenance-free well water treatment system.

Main Features & Benefits

Sulfur Treatment Method:

This sulfur lowering system works based on what is known as continuous injection technology. It uses hydrogen peroxide in the oxidation process that makes it possible for its catalytic carbon filters to remove sulfur and hydrogen sulfate from your tap water.

It will reduce sulfur content in your tap water to a level that is less than 30 ppm. This will eliminate all of the different sulfur-related problems that you are experiencing with your water. 

Other Contaminants Removed or Reduced:

This system is specifically designed to target sulfur, iron, and manganese.  It will also inhibit the growth of sulfur and iron-feeding bacteria and remove any silt, sand, sediment, and cloudiness that is present in your incoming water.

Ease of Installation & Maintenance:

Because it’s more complex to set up a hydrogen peroxide injection treatment system, you will want to have this professionally done.

The operation of this sulfur lessening system is made simple by its control app and automatic backwashing feature but at the same time, you will have to manually refill the hydrogen peroxide storage tank when it runs low.

Flexxapp

Its Catalytic Carbon filtration media also needs to be refreshed periodically.

No other maintenance is needed to keep this sulfur in water removal working efficiently.

System Flow Rate:

Here is another one of those water filtration systems that can be used in homes that have up to 4 bathrooms. That’s because it boasts having a flow rate of 15-gallons per minute.

Construction & Durability:

This sulfur system has a decorative and durable chrome exterior tank that will resist corrosion over a very long time. All of the components in the system are designed to make it hold up well for 10 plus years.

#4 Pelican Sulfur Water System

pelican-sulfur-water-system

This is a dual-tank whole-house sulfur water filter system from the reputable water filtration company Pentair. It’s an injection-type system that uses chlorine as a means to convert sulfur (hydrogen sulfide) into a filterable form.

You can count on it to remove several other contaminants from your well water too. This system can also filter out any contaminant particle that is 5-microns in size or larger and kill bacteria.

The setup of this filtration system is a little complicated and it takes some periodic maintenance but overall, it’s pretty simple to operate and maintain. It’s also a well-made system but several parts need to be connected to make it work.

Main Features & Benefits

Sulfur Treatment Method:

Adding chlorine to tap water where sulfur is present works in two ways. The first is that when sulfur contacts chlorinated water it forms big yellow chunks that are easy to filter out.

Chlorine can also destroy the bacteria in well water that feeds on sulfur and, in turn, produces the hydrogen sulfide gas that causes the sulfur smell and other problems in water.

The chlorine this sulfur system uses to resolve hydrogen sulfide issues in tap water is then removed by the carbon filter in its main tank.

Other Contaminants Removed or Reduced:

You get much more than just odor free water with this combination injection and filtration tank system. Due to its 5-micron filtration ability, it will also remove high concentrations of chlorine, sediment, pesticides, copper, zinc, pharmaceuticals, industrial solvents, and herbicides.

Ease of Installation/Operation/Maintenance:

I have had people say that this is an easy unit to install but I am not buying that. You will probably need professional installation to plumb in its tanks an injection system into your incoming water line.

Operation is easy because the system has no control head and just runs continuously. It does require periodic chlorine tank refills and changing out the sediment pre-filter when it gets dirty. A helpful metering pump comes with the system too. 

System Flow Rate:

At 14 gallons per minute, this has a more than acceptable flow rate. As with the other sulfur in water removal systems on our list of the best ones, it is more than serviceable for use in homes with 1 to 4 bathrooms.

Construction/Durability:

This system is fairly well built but it has more small parts to attach than any other sulfur treatment device on our list. 

Some of that is offset by the fact that it does not have an electronic control head that can break down and its stainless steel filtration tank is very durable and corrosion-resistant.

Warranty/Guarantees:

I am not a big fan of the warranty that comes with these water systems. That includes the manufacturer standing behind that tank, valve, and electronics for only 5-years and the rest of the parts on the system for 1-year.

Its 90-day satisfaction guarantee does give peace of mind when purchasing this unit.

Price:

This is the lowest-priced sulfur lowering system on our list but don’t let that mislead you. Many would still consider it to be a somewhat expensive piece of water filtration equipment.   

Pros:

  • 5-micron water filter
  • Effective chlorine injection system
  • Dual tank design
  • Filters out more than just sulfur
  • 90-day satisfaction guarantee
  • No backwashing necessary
  • Does not need an electric hookup

Cons:

  • High initial cost
  • Warranty could be better for the price
  • Requires periodic chlorine refills and filter changes
  • Initial setup is difficult
  • Needs chlorine refills and sediment pre-filter changeouts

Sulfur Water Filter Buyers Guide

Here is some good information to know before you start shopping for sulfur treatment equipment.

What is Sulfur?

Many people do not realize that sulfur is actually a non-metallic element that has its own place on the periodic table. It’s naturally occurring and is often present in rocks, rock layers, and areas that have had previous volcanic activity.

This element is also an essential compound that’s found in every living cell.

Health Issues with Sulfur

Although the CDC considers sulfur in water to have low toxicity, it still can contribute to such health issues as dehydration and diarrhea. High sulfur concentrations in tap water can also cause that water to be an eye and skin irritant. 

It’s also not good to breathe large amounts of hydrogen sulfide, So you shouldn’t expose yourself to the sulfur smell for long. A good sulfur water filter can eliminate this problem altogether. 

Getting rid of the sulfur in your water will also prevent scale buildup on pipes. That’s necessary because this buildup which contains trace metals will eventually find its way into your body when it comes loose and goes back into the water supply.

This is why I will always recommend the purchase of a water filter that removes sulfur if you have any form of this element present in your water.

How Does Sulfur Get into Your Water?

As was mentioned, sulfur is often present in rocks and rock layers. It can end up in water sources through chemical reactions that take place with soil, rocks, and coal deposits. 

Sulfur-consuming bacteria that like low oxygen environments are found in groundwater, wells, and plumbing systems. These can also introduce hydrogen sulfide into your drinking water source. 

How to Test Your Water for Sulfur?

health-metric-well-water-test-kit

Both lab and home testing can determine if you indeed do have sulfur water. 

The Health Metric Well Water Test Kit is one of the simpler ones to use to detect the presence of hydrogen sulfide in your household water. 

More details on this test kit and other reliable water testing options can be read about in our  Best Water Test Kits article.  

Seeing what contaminants that you need to remove from your incoming water will help you better identify the water systems that eliminate hydrogen sulfide that should interest you. 

It’s also never a bad idea to know what other organic matter and contaminants are lingering in your water supply too. That will also help you determine what water filtration system best meets your sulfur and other impurities removal needs. 

Types of Filters that Remove Sulfur

reverse-osmosis-system-1

Granulated activated carbon filters and reverse osmosis systems are the only types of filters that can eliminate sulfur from tap water but neither of these is considered to be reliable and effective on its own.

That’s why a sulfur water filter often is combined with oxidation or chemical injection equipment to make it easier for them to eliminate sulfur and hydrogen sulfide from household water.   

It then makes it easier for an activated carbon filter to do its job. Try to stay away from water filters that use the poisonous substance potassium permanganate.   

Sulfur Water Filter FAQs

Here are some of the most common questions that I get when it comes to the presence of sulfur in water and a water filter that can end issues related to the presence of sulfur in water.                 

Why Does My Water Smell Like Rotten Eggs Or Sulfur?

The rotten egg smell in water is caused by hydrogen sulfide gas. This is produced by the various types of bacteria that feed on sulfur that are often present in well water. 

Do Typical Water Filters Remove Sulfur?

No, because oxidation or chemical injection is required to do this and most typical water filtration devices do not have that capability. So you need a special water filtration system to do this task.

Can You Drink Well Water With Sulfur In It?

Yes, but perhaps it’s better to ask why you would drink water with sulfur content in it. Although it’s considered safe to drink, it may cause some minor digestive system problems and its smell and taste may not make your water desirable to consume.

Will A Carbon Filter Remove Sulfur Smell?

No, because an ordinary carbon-based water filter cannot remove the hydrogen sulfide which is the source of the rotten egg smell in tap water. 

So an activated carbon filter alone will not get you odor-free water. A water filtration system that uses oxidation or chemical injection is best. 

Some Final Thoughts on Sulfur Removal Systems

Even after experiencing just a few times the effects of smelling hydrogen sulfide in tap water and how it impacts water’s taste, that’s enough for me to never want to deal with the problems that sulfur in tap water causes.

Yes, I realize that the presence of sulfur in water does not cause serious health issues and the systems that remove it are expensive to install.

I do, however, still believe the drawbacks to sulfur-laden water far outweigh the investment that is necessary to get a water filter that eliminates sulfur.

This is especially true if you buy a system that removes many other harmful contaminants in the water that you and your family drink every day.
