Introduction to Alkaline Water Pitchers

What are Alkaline Water Pitchers?

Alkaline water pitchers are specialized water filtration devices designed to both purify tap water and increase its pH level to make it more alkaline. These pitchers typically raise the pH of water to between 8.5 and 9.5 on the pH scale, compared to neutral tap water which has a pH of 7 (Santevia, n.d.).

The basic concept behind alkaline water pitchers is that they filter out contaminants while also adding minerals that increase alkalinity. As water passes through the multi-stage filtration system in the pitcher, impurities are removed and alkaline minerals are infused into the water. This process not only improves the taste and quality of drinking water but also creates water with a higher pH that some believe may have health benefits.

Alkaline water pitchers work through a combination of physical filtration and chemical processes. As tap water is poured into the top reservoir of the pitcher, it slowly drips down through a cartridge containing various filter media. This typically includes activated carbon to remove chlorine and improve taste, as well as mineral balls or other alkalizing materials that raise the pH level. The filtered, alkalized water then collects in the main pitcher reservoir, ready for drinking.

Key Components of Alkaline Water Pitchers

The heart of an alkaline water pitcher is its filtration cartridge, which contains several key components:

  1. Activated carbon: This highly porous form of carbon acts as an adsorbent, trapping chlorine, volatile organic compounds (VOCs), and other contaminants that affect taste and odor. Activated carbon is extremely effective at improving the basic quality and flavor of tap water.

  2. Mineral balls: These are typically made of materials like tourmaline, zeolite, or ceramic and are infused with alkaline minerals like calcium, magnesium, and potassium. As water passes over the mineral balls, these beneficial minerals are released into the water, raising its pH level.

  3. Ion exchange resin: Some pitchers include ion exchange materials that can remove heavy metals like lead and copper by swapping them for less harmful ions.

  4. Far-infrared ceramics: Certain high-end pitchers incorporate far-infrared emitting ceramics, which are claimed to reduce water molecule cluster size for better hydration, though scientific evidence for this effect is limited.

  5. Other filter materials: Depending on the specific model, pitchers may include additional filtration media like KDF (Kinetic Degradation Fluxion) to remove chlorine and heavy metals, or ceramic filters for fine particle removal.

The combination and quality of these filter components determine the overall effectiveness of the alkaline water pitcher in both purifying water and increasing its pH level.

Primary Functions

Alkaline water pitchers serve three main functions:

  1. Removing contaminants from tap water: The activated carbon and other filter media work to reduce chlorine, sediment, and various chemical contaminants that may be present in municipal tap water. This improves both the safety and palatability of drinking water.

  2. Raising water pH level: Through the addition of alkaline minerals, these pitchers increase the pH of water from the neutral 7 to a more alkaline range of 8.5-9.5. This is the defining feature of alkaline water pitchers compared to standard water filters.

  3. Adding beneficial minerals: As the filtration process removes impurities, it simultaneously adds back beneficial minerals like calcium, magnesium, and potassium. This mineral fortification can potentially improve the nutritional value of the water.

By combining these functions, alkaline water pitchers aim to produce clean, great-tasting water with a higher pH level and mineral content than typical filtered or tap water.

Potential Benefits of Alkaline Water Pitchers

Water Quality Improvement

One of the primary benefits of alkaline water pitchers is their ability to significantly improve overall water quality. These devices are effective at removing a wide range of common contaminants found in tap water:

  • Chlorine: Activated carbon filtration can remove up to 99% of chlorine, eliminating the associated taste and odor (Brita, n.d.).
  • Heavy metals: Many alkaline water pitchers can reduce levels of lead, copper, and mercury, which can be harmful even in small amounts.
  • Pesticides and pharmaceuticals: Advanced filters may reduce trace amounts of pesticides and pharmaceutical residues that can make their way into water supplies.

A study by Kohlová et al. (2020) found that pitcher-type water filters were effective at removing various contaminants, with removal rates of up to 100% for certain substances. However, the researchers noted that effectiveness varied between brands and depended on proper maintenance.

Beyond contaminant removal, alkaline water pitchers often significantly enhance the taste and odor of tap water. By removing chlorine and other chemicals that contribute to off-flavors, these pitchers can make water more palatable, potentially encouraging increased hydration.

Mineral Fortification

A unique aspect of alkaline water pitchers is their ability to add beneficial minerals to the water during the filtration process. Common minerals added include:

  • Calcium: Important for bone health and cellular function
  • Magnesium: Involved in hundreds of biochemical reactions in the body
  • Potassium: Crucial for heart function and muscle contraction

While the amounts of minerals added are generally small, they may contribute to overall mineral intake. A study by World Health Organization (2009) suggested that drinking water can be a meaningful source of essential minerals, particularly in areas where dietary intake may be insufficient.

It's important to note that while mineral addition is a feature of alkaline water pitchers, the health implications of consuming mineralized water are still a subject of ongoing research. Some studies have suggested potential benefits:

  • A review by Quattrini et al. (2016) found that magnesium-rich mineral water may have beneficial effects on cardiovascular health.
  • Research by Wynn et al. (2009) indicated that calcium and magnesium in drinking water may contribute to reduced risk of osteoporosis.

However, more comprehensive studies are needed to definitively establish the health impacts of mineral-enhanced water from alkaline pitchers.
