Save Money with DIY Alkaline Water Filters

August 30, 2023 5 min read

Alkaline water has gained popularity in recent years due to its numerous health benefits.


However, purchasing bottled alkaline water or investing in a commercial alkaline water filter can be expensive. A DIY alkaline water filter is an affordable alternative that allows you to enjoy the benefits of alkaline water without breaking the bank. In this article, we will explore various DIY alkaline water filter methods and share tips for maintaining your filter to ensure optimal performance.

What is Alkaline Water?

Alkaline water has a higher pH level than standard tap water. It typically ranges from 8 to 10. The pH scale ranges from 0 to 14, with 7 being neutral. A pH level below 7 indicates acidity, while a pH level above 7 indicates alkalinity. Alkaline water contains minerals such as calcium, magnesium, and potassium, which can help neutralize acidity in the body and promote overall health and well-being.

Benefits of Alkaline Water


Some of the potential benefits of alkaline water include:

  1. Improved hydration: Alkaline water molecules are smaller and more readily absorbed by the body, leading to better hydration.

  2. Neutralization of acidity: Consuming alkaline water can help neutralize acidity in the body, promoting a balanced pH level and supporting overall health.

  3. Enhanced nutrient absorption: The increased hydration and reduced acidity associated with alkaline water can improve the body's ability to absorb essential nutrients.

  4. Antioxidant properties: Alkaline water contains negatively charged hydroxyl ions, which act as antioxidants to neutralize harmful free radicals in the body.

  5. Improved bone health: Research suggests that alkaline water may help support bone health by reducing calcium loss and promoting the formation of new bone tissue.

Building Your DIY Alkaline Water Filter

  1. Choose your filtration method: The first step in building your DIY alkaline water filter is selecting a filtration method. There are several options, including activated carbon filters, reverse osmosis systems, and sediment filters. Each method has its own advantages and drawbacks, so research each option to determine the best fit for your needs.

  2. Select your alkalizing agent: The next step is to choose an alkalizing agent that will raise the pH of your water. Common alkalizing agents include calcium and magnesium, which are essential minerals that contribute to overall health. Other options include Maifan stones, which release essential minerals into the water, and magnesium prill beads, which increase the magnesium content of your water. Consider your desired pH level and mineral content when selecting an alkalizing agent.

  3. Assemble your filter: Once you have chosen your filtration method and alkalizing agent, you can begin assembling your DIY alkaline water filter. You will need a water filter housing, filter cartridges, tubing, and fittings. Follow the manufacturer's instructions for assembling your filter, ensuring all connections are secure and leak-free.

  4. Install your alkalizing agent: After assembling your filter, add your chosen alkalizing agent to the appropriate filter cartridge or stage. Follow the manufacturer's recommendations for the correct amount of alkalizing agent and placement within the filter.

  5. Test your water: After installing your DIY alkaline water filter, test your water's pH level using a pH test kit or digital pH meter. This will ensure your filter is effectively raising the pH of your water to the desired level. If necessary, adjust the amount of alkalizing agent to achieve the optimal pH.

  6. Maintain your filter: Regular maintenance is essential for the longevity and effectiveness of your DIY alkaline water filter. Replace filter cartridges and replenish alkalizing agents as needed, following the manufacturer's guidelines. Test your water's pH periodically to ensure it remains at the desired level.

DIY Alkaline Water Filter Methods


There are several methods for creating a DIY alkaline water filter:

  1. Baking Soda: Adding a small amount of baking soda to your water can raise its pH level and create alkaline water. However, this method can result in a slightly salty taste.

  2. pH Drops: pH drops are concentrated alkalizing agents that can be added to your water to increase its pH level. These drops are available at health food stores and online retailers.

  3. Alkalizing Water Pitcher: Alkalizing water pitchers are designed to filter and alkalize tap water simultaneously. These pitchers often contain a filter cartridge with a mix of alkalizing minerals that release into the water as it passes through the filter.

  4. Water Ionizer: Water ionizers are electronic devices that separate water into alkaline and acidic streams using a process called electrolysis. Although water ionizers can be expensive, they produce high-quality alkaline water with customizable pH levels.

  5. DIY Alkaline Water Filter System: You can create your DIY alkaline water filter system by combining a standard water filter with an alkalizing agent such as mineral stones, magnesium prill beads, or a ceramic dome filter. This method allows you to enjoy the benefits of filtered and alkaline water simultaneously.

Tips for Maintaining Your DIY Alkaline Water Filter

  1. Regular maintenance: To ensure optimal performance, clean and replace your filter components regularly. Follow the manufacturer's guidelines for specific maintenance instructions.

  2. Test your water quality: Regularly test your tap water to monitor the level of contaminants. If your water has a high level of contaminants, consider installing a pre-filter or using a reverse osmosis system to remove impurities before alkalizing.

  3. Experiment with different alkalizing agents: Try different alkalizing agents to find the one that works best for you. Each agent offers unique benefits, so experiment with various options to achieve the desired taste and mineral content.

  4. Monitor your water's pH level: Regularly test the pH level of your filtered water to ensure it remains within the desired range. pH test strips or a digital pH meter can help you monitor the alkalinity of your water.

  1. Stay informed about water regulations and quality in your area: Keep up-to-date with any changes in water quality or regulations in your area. This information can help you adjust your DIY alkaline water filter system to provide the best quality water possible.

  2. Educate yourself on water filtration technologies: Stay informed about advancements in water filtration technologies to ensure you are using the most effective and efficient method for creating alkaline water at home.

  3. Consult with a water treatment professional: If you have concerns about the quality of your tap water or need assistance in setting up your DIY alkaline water filter system, consult with a water treatment professional for expert advice.


A DIY alkaline water filter is an affordable and effective way to enjoy the numerous health benefits of alkaline water. By creating your filter system or using readily available alkalizing agents, you can save money and take control of your water quality. Regular maintenance and monitoring of your water's pH level will ensure optimal performance and long-lasting benefits. With a little research and experimentation, you can create a customized alkaline water filter system that meets your specific needs and promotes a healthier lifestyle.
