What Is Alkaline Water and How Can You Make It at Home?
If you’ve ever found tap water too harsh, acidic, or unpleasant, you’re not alone. Water quality varies across regions, and for many people, the solution is turning to bottled alkaline water. But is that the best approach? What makes water alkaline, and can you achieve it without the environmental impact of plastic waste?
Alkaline water is often promoted for its sublime benefits. It can neutralise acidity, improve hydration, and enhance mineral intake. However, not all alkaline water is created equal. Some sources naturally contain essential minerals like calcium and magnesium. Alternatively, others use artificial methods to raise pH. Understanding how water becomes alkaline can help you make informed choices about your drinking water. No matter if you're after better taste, improved water quality, or a more sustainable alternative to bottled options. Phox specialises in refillable water filtration solutions that enhance alkalinity without plastic waste.
We'll cover the best ways to make alkaline water at home and how to choose a method that aligns with your health and environmental values.
What Makes Water Alkaline?
Water is considered alkaline when its pH level exceeds 7, meaning it contains fewer hydrogen ions (H⁺) and more hydroxide ions (OH⁻). However, pH alone does not determine whether water is alkaline – its mineral composition plays a crucial role. Bicarbonates, carbonates, and hydroxides from minerals raise water's alkalinity. These minerals include calcium, magnesium, and potassium.
The Science Behind Alkaline Water
The pH scale ranges from 0 to 14, with pure water sitting at neutral pH 7. In contrast:
- Acidic water (pH < 7) includes beverages like coffee (pH 5) and soft drinks (pH 3). Due to their high acidity levels, these drinks can contribute to enamel erosion and acid reflux over time.
- Neutral water (pH 7) includes most tap and filtered water. It is generally considered safe and balanced for daily consumption. However, depending on the source, it may still contain impurities.
- Alkaline water (pH 8-10) includes water with naturally occurring or added minerals. Many believe it has additional benefits, such as improved hydration and acid neutralisation.
According to the UK’s Drinking Water Inspectorate (DWI), tap water typically ranges between pH 6.5 and 9.5, depending on the region and treatment process. Alkaline water occurs when it flows over mineral-rich surfaces, such as limestone and chalk. It's this process that dissolves alkaline compounds into the water.
How Can You Make Alkaline Water at Home?
Instead of relying on bottled alkaline water, there are several sustainable ways to alkalise your water at home. Each method varies in effectiveness and environmental impact.
1. Alkaline Water Filters
The most efficient and sustainable method is using a refillable alkaline water filter. These filters raise the pH naturally by adding essential minerals while filtering out contaminants. The Phox Alkaline Pack is a reusable solution that boosts alkalinity without contributing to plastic waste. Unlike single-use filters, refillable options eliminate unnecessary plastic disposal.

2. Baking Soda Method
Baking soda, also known as sodium bicarbonate, is one of the simplest ways to make water more alkaline. Adding half a teaspoon per litre raises the pH by neutralising excess acidity. While this method is quick and inexpensive, it alters the taste and isn't ideal for daily consumption. So, do you want a long-term alkaline water solution that maintains excellent taste and natural mineral balance? If you do, a refillable alkaline water filter is a better choice.
3. Lemon Water (Surprisingly Alkaline!)
Lemons are acidic. Yet, once metabolised, they produce alkaline byproducts, which help maintain the body's pH balance. For the best effect, let lemon slices sit in water for at least 30 minutes before drinking. Many prefer this method for its natural detox properties.

Natural vs Artificial Alkaline Water
Not all alkaline water is the same. Some sources are naturally alkaline due to geology, while others are artificially enhanced. Understanding the difference can help us make informed choices about water quality.
Naturally Alkaline Water
Alkaline water is naturally formed when groundwater moves through mineral deposits. It absorbs essential elements that increase pH and contribute to a refreshing taste. Some UK spring water sources naturally contain calcium, magnesium, and bicarbonates. These minerals don't just enhance the taste but also contribute to essential daily nutrient intake.
Artificially Alkaline Water
Artificial methods increase water pH through:
- Electrolysis (ionisation): Using electricity to separate acidic and alkaline components, creating higher pH water artificially.
- Alkaline mineral infusions: Adding calcium, magnesium, and potassium to raise pH. This method replicates natural alkaline water but may not always provide the same mineral balance.
In the UK, alkaline bottled water consumption has surged. For example, ACTIPH, the UK's first ionised alkaline bottled water brand, doubled sales during the pandemic. However, bottled alkaline water contributes to plastic pollution. Therefore, home filtration like ours offers a far more sustainable option for eco-conscious souls.
Enjoy Alkaline Water Without the Waste
Drinking alkaline water shouldn’t cost the environment. Bottled alkaline water adds waste to landfills, and single-use filters require frequent replacement. The good news is that you can enjoy great-tasting alkaline water without the single-use plastic waste.
Phox’s Alkaline Refillable Filter pack is the UK’s leading solution for single-use plastic free water filtration. It can raise the pH, radicalise the taste, and reduce impurities in your water in an eco-friendly and cost-effective way. Our 3-month Alkaline Refill Pack is specially designed to keep your filtration system performing at its best. Better yet, it's delivered straight to your door for convenience.
