Showerhead water filters use various materials to make the water you shower in clean and contaminant free. Here are the most common materials used:
Activated Carbon
Activated carbon is the most used material in water filtration. It works through adsorption where contaminants are trapped in the tiny pores of the carbon material.
-
How it works: Activated carbon has a large surface area with many tiny pores. As water flows through the filter, impurities like chlorine, volatile organic compounds (VOCs) and odors are adsorbed onto the surface of the carbon.
-
Benefits: Removes chlorine, improves water taste and smell, and reduces other organic impurities.
-
Common uses: Used in household water filters, including showerheads, to improve water quality.
KDF (Kinetic Degradation Fluxion)
KDF is a high purity copper-zinc formulation that uses a redox (oxidation-reduction) reaction to remove contaminants.
-
Explanation: KDF media converts harmful contaminants into harmless components. For example, it can convert free chlorine into water soluble chloride which is then washed away.
-
Benefits: Effective against chlorine, lead, mercury, iron and hydrogen sulfide. Also inhibits growth of bacteria, algae and fungi.
-
Common uses: Used in combination with other filtration media in showerheads and whole-house water filters.
Vitamin C
Vitamin C (ascorbic acid) is being used more and more in shower filters because it can neutralize chlorine and chloramines.
-
Function: Vitamin C reacts with chlorine and chloramines, neutralizes them and makes the water safer for skin and hair.
-
Benefits: Reduces skin irritation and dryness caused by chlorine, improves hair health, and enhances showering experience.
-
Effectiveness: Good for people with sensitive skin or allergic to chlorine.
Ceramic Balls
Ceramic balls are a natural filtration medium that can purify water by removing impurities.
-
Description: These balls are made from natural materials and remove contaminants and improve water quality.
-
Role in filtration: Removes heavy metals, chlorine and bacteria from water.
-
Health benefits: Provides cleaner water for healthier skin and hair.
-
Common use cases: Found in many eco-friendly shower filters and water purifiers.
Calcium Sulfite
Calcium sulfite is known to remove chlorine and heavy metals from water especially in hot water environments.
-
How it purifies water: Calcium sulfite works well at high temperatures making it ideal for use in showerheads where hot water is present.
-
Benefits: Removes chlorine and heavy metals fast and effective.
-
Limitations: Less effective in cold water and may need to be replaced frequently depending on water quality.
