Alkaline Filter
Alkaline Filter Function in Water Purification
An alkaline filter is designed to improve the pH level of purified water and enhance its mineral content. This filter is often used as an additional stage in water filtration systems, particularly in reverse osmosis (RO) systems, where the water can become slightly acidic after the removal of minerals.
Function of the Alkaline Filter
- Increases pH Levels:
- The alkaline filter raises the pH of the purified water, making it more alkaline. This is achieved by adding back healthy minerals like calcium, magnesium, and potassium that were removed during earlier filtration stages.
- Adds Essential Minerals:
- Reintroduces beneficial minerals, which not only improve the water’s taste but also contribute to better health. These minerals are essential for maintaining proper body functions.
- Improves Taste and Freshness:
- By balancing the pH and adding minerals, the alkaline filter enhances the taste and freshness of the water, making it more appealing for drinking.
- Balances Acidity:
- Counteracts the slight acidity of RO-purified water, creating a more neutral or slightly alkaline water profile that some believe is better for hydration and overall wellness.
- Provides Antioxidant Properties:
- Some alkaline filters also produce water with a negative oxidation-reduction potential (ORP), which is associated with antioxidant benefits.
Advantages of Alkaline Filters
- Promotes better hydration due to improved water absorption.
- May help neutralize acidity in the body and support pH balance.
- Enhances taste, making water more pleasant to drink.
- Provides trace minerals for overall health benefits.
When to Use an Alkaline Filter
- Post RO Filtration: Ideal for systems where demineralized water is produced, such as reverse osmosis systems.
- Low pH Water Supply: If the source water is naturally acidic, an alkaline filter helps balance the pH.
Maintenance
- Replacement Interval: Alkaline filters typically need to be replaced every 6–12 months, depending on usage and water quality.
- Signs of Wear: Reduced mineral taste or lower pH levels in the filtered water indicate the need for replacement.
