Will a Brita Filter Remove Sulfur?

Jason Barrett Jason Barrett | | Brita

Wondering if or will a Brita filter remove sulfur from your water? I was in the same position before I did some digging.

Find out more about how Brita filters work and their effectiveness in removing different contaminants.

Will a Brita Filter Remove Sulfur?

Yes, a Brita filter is capable of removing some sulfur from water.

  • Sulfur is often present in water as hydrogen sulfide gas, which can give water an unpleasant smell and taste, similar to rotten eggs.
  • Brita filters utilize activated carbon to reduce common impurities, including certain chemicals, odors, and tastes.
  • Activated carbon has the ability to adsorb hydrogen sulfide, thereby reducing its presence in the water and improving its quality.

Brita filters are not specifically designed to target sulfur removal, and their effectiveness may vary depending on the concentration of sulfur and other factors.

Will a Brita Filter Remove Sulfur Stains?

Brita filters are not designed to remove sulfur stains from water. Sulfur stains typically occur when water with high sulfur content comes into contact with certain surfaces, such as:

  • sinks
  • faucets
  • clothing

The discoloration or staining is a result of chemical reactions between sulfur and the materials. Brita filters primarily focus on improving the taste and odor of water by reducing impurities.

To address sulfur stains, it is necessary to explore other methods such as using water softeners or specific stain removers

Can a Brita Filter Remove Sulfates from Water?

Answer: Brita filters are not specifically designed to remove sulfates from water. Sulfates are dissolved salts that can be present in water sources.

Brita filters primarily target impurities such as chlorine, heavy metals, and certain organic compounds.

While the activated carbon filter used in Brita pitchers and dispensers can reduce some sulfate levels, it may not be as effective as specialized filters designed specifically for sulfate removal.

If you have concerns about sulfate levels in your water, it is recommended to explore alternative filtration options that are specifically designed to target sulfates.

Why Does My Water Have a Sulfur Smell?

The presence of a sulfur smell in water is often due to the presence of hydrogen sulfide gas.

  1. Hydrogen sulfide can occur naturally in groundwater sources or be a result of certain types of bacteria breaking down organic matter in water.
  2. When water with high levels of hydrogen sulfide is heated or comes into contact with air, it can produce a distinct rotten egg smell.
  3. The sulfur smell is typically more noticeable in hot water due to the gas being released at higher temperatures.

While the odor may be unpleasant, low levels of hydrogen sulfide in drinking water are generally not harmful to health.

Are Traces of Sulfur in Water Toxic?

Traces of sulfur in water are generally not considered toxic. Sulfur is a naturally occurring element and can be found in various forms, including sulfates and hydrogen sulfide.

In low concentrations, sulfates and hydrogen sulfide are not harmful to human health. In fact, sulfates are commonly found in many natural water sources and are even present in certain foods.

High concentrations of hydrogen sulfide gas in the air can be irritating and potentially harmful if inhaled in large amounts.

How to Remove Sulfur From Water

To remove sulfur from water, there are several methods and treatment options available. Here are a few commonly used techniques:

  1. Activated Carbon Filtration: Activated carbon filters can effectively remove low to moderate levels of hydrogen sulfide gas and reduce the sulfur smell and taste in water. These filters work by adsorbing the sulfur compounds onto the carbon surface.
  2. Oxidation: Oxidation methods, such as using chlorine or hydrogen peroxide, can help convert hydrogen sulfide into solid particles that can be filtered out. This process is often combined with activated carbon filtration for better results.
  3. Aeration: Aeration involves exposing the water to air, which allows the hydrogen sulfide gas to escape. Aeration can be achieved through air-stripping towers, cascading water, or air injection systems.
  4. Chemical Injection: Chemicals like chlorine dioxide or potassium permanganate can be injected into the water to oxidize and remove sulfur compounds. This method is often used for larger-scale or well water treatment systems.
  5. Ion Exchange: Ion exchange systems can effectively remove sulfates from water by exchanging sulfate ions with chloride ions or other suitable exchange materials.

It’s important to note that the choice of treatment method depends on the specific sulfur compounds and concentrations present in your water.

Why Does My Brita Smell Bad?

Answer: There can be several reasons why your Brita may develop a bad smell over time. Here are a 4 possible causes:

1. Contaminated Filter

If you notice a foul odor coming from your Brita, it could be due to contaminants that have accumulated in the filter over time.

Filters can trap impurities, bacteria, and organic matter, which can lead to unpleasant smells.

2. Mold or Mildew Growth

Moisture can accumulate in the pitcher or other parts of the Brita, creating an environment conducive to mold or mildew growth. If you don’t clean and dry the pitcher properly between uses, mold or mildew can develop, leading to a bad smell. It’s important to clean the pitcher, lid, and any removable parts regularly with mild soap and water.

3. Stagnant Water

Allowing water to sit in the Brita pitcher for an extended period without use can result in stagnant water, which can develop an unpleasant odor.

To prevent this, empty and refill the pitcher regularly, especially if it hasn’t been used for a while.

4. Contaminated Tap Water

In some cases, the smell may not be coming from the Brita itself but from the tap water you are using. Certain minerals, chemicals, or organic compounds present in the tap water can cause an unpleasant odor.

In such cases, using a different water source or considering an additional water treatment method may be necessary.


Brita filters are designed to reduce certain impurities and improve the taste of water, but they may not effectively remove sulfur compounds such as hydrogen sulfide.

Sulfur in water can cause unpleasant odors and taste, and specialized treatment methods may be necessary for effective removal.

If you are concerned about sulfur in your water, have your water tested and explore alternative filtration options specifically designed for sulfur removal, if needed.
