What To Look For When Choosing The Best Sulfur Filter


Here are the traits of the best hydrogen sulfide filter system that you should key on when shopping for one of these filtration systems:

Sulfur Treatment Method

The water purifier works by removing hydrogen sulfide and sulfur-consuming bacteria, which cause sulfate-related issues in tap water. Most water filtration systems work very straightforwardly 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 of a whole house water filter. For example, most catalytic carbon filters can remove chlorine, and more from water but not all water filters are created equal. 

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 it needs.

This includes a device with such features as a remotely programmable control head.


System Flow Rate

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

Ensure that you know the working flow rate of any sulfur filtration system you are thinking about buying so that it doesn’t affect your water pressure.

Construction & Durability

The chances are that you will be installing your whole house water system 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.


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.      


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 in choosing the best sulfur water filtration system that removes or reduces hydrogen sulfide.

Sulfur Water Treatment Systems Buyers Guide


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

What is Sulfur or Hydrogen Sulfide?

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, diarrhea, and eye irritation. High sulfur concentrations in tap water can also cause that water to be a skin irritant, so it is important to filter sulfur out of house water. 

It’s also not good to breathe large amounts of hydrogen sulfide, so you shouldn’t expose yourself to the sulfur smell for long. Good sulfur filter systems 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 purchasing a sulfur removal system if you have any form of this element present in your water to get pure, filtered water to avoid health issues and eye irritation.

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 table 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?

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 and drinking water. 


Our Best Water Test Kits article can read more details on this test kit and other reliable water testing options.  

Seeing what contaminants 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 iron and sulfur removal needs. 

What Types of Water Filter Removes Sulfur?

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.

A hydrogen sulfide water filter is often combined with oxidation or chemical injection equipment to make it easier for them to eliminate sulfur and hydrogen sulfide from drinking 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 the water and a water filter that can end issues related to the presence of hydrogen sulfide in the 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, 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 hydrogen sulfide 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 smell, 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 air injection is best. 

Can You Find Sulfur In Hot Water?

If your cold and hot water both have a rotten-egg odor, it’s most likely because of hydrogen sulfide in your water supply. The bacteria use the septic tank’s contents as a source of food and, in so doing, produce hydrogen sulfide gas.

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 never to 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.

However, I still believe the drawbacks to sulfur-laden water far outweigh the investment that is necessary to get water filtration systems that eliminate hydrogen sulfide.

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.
