Water is essential for our survival, but the type of water we should be drinking isn’t always clear. Alkaline water filters have become increasingly popular in health and wellness circles, prompting many to consider adding them to their homes.
The Science of Alkaline Water
Alkaline water filters increase the pH level of drinking water, typically to a range between 8 and 9.5. This is accomplished through electrolysis, which separates water into acidic and alkaline components.
However, these filters do more than just adjust pH levels.
Most alkaline water filters are multi-stage systems that incorporate activated carbon filtration and often reverse osmosis before the alkalinization process. This means they make your water more alkaline and purify it by removing contaminants like chlorine, lead, and some bacteria.
The theory behind alkaline water stems from the idea that modern diets tend to be acidic. Drinking alkaline water may help balance our body’s pH levels, potentially leading to better hydration, improved digestion, and even anti-aging effects.
However, our bodies are quite adept at regulating pH on their own, and the scientific community continues to debate the extent of these benefits.
Types of Alkaline Water Filters
When selecting an alkaline water filter for your home, you’ll encounter a range of options. Let’s explore the main types:
Pitcher Filters
Pitcher filters are an excellent entry point for those curious about alkaline water. These affordable options typically cost between $50 and $100 and need no installation.
Simply fill the pitcher with tap water, and the filter does the rest.
However, they have limited capacity and need frequent filter changes.
Pitcher filters are ideal for people or small households who want to try alkaline water without a significant investment. They’re portable and can be easily stored in the refrigerator.
Keep in mind that the alkalinization process may be less robust compared to more advanced systems.
Countertop Systems
Countertop alkaline water filters offer a step up from pitchers in terms of capacity and filtration capabilities. These units connect to your faucet and sit on your kitchen counter.
They provide a constant supply of alkaline water without the need for frequent refilling.
Countertop systems often incorporate more advanced filtration stages, potentially removing a wider range of contaminants. They’re a good choice for those who want a dedicated alkaline water source without the complexity of under-sink installation.
However, they can take up valuable counter space and may not blend seamlessly with your kitchen decor.
Under-Sink Systems
For those serious about incorporating alkaline water into their daily lives, under-sink systems offer the most comprehensive filtration and alkalinization. These systems are installed beneath your kitchen sink and typically come with a separate faucet for dispensing filtered, alkaline water.
Under-sink alkaline water filters often include many filtration stages, such as sediment filters, activated carbon, and reverse osmosis membranes, before the water undergoes alkalinization. This results in highly purified, alkaline water.
While they’re out of sight, these systems can be pricey, with high-end models costing over $3,000.
Whole House Systems
The ultimate commitment to alkaline living comes in the form of whole house alkaline water systems. These treat all the water entering your home, providing alkaline water from every tap.
While this offers unparalleled convenience, whole house systems are expensive and complex to install.
Whole house alkaline water filters are best suited for those who want to fully embrace alkaline water for all household uses, including bathing and laundry. However, the high cost and potential need for professional installation make them a significant investment.
Factors to Consider When Choosing an Alkaline Water Filter
Selecting the right alkaline water filter involves weighing several factors:
- Budget: Consider both the initial cost of the system and ongoing expenses for filter replacements and maintenance.
- Available Space: Assess where you can install or place the filter in your home.

Installation Process
The installation process for your alkaline water filter will vary depending on the type of system you choose. Here’s a general overview of what to expect:
Pitcher and Countertop Systems
These are typically the easiest to set up. For pitchers, you’ll simply need to gather the filter components and fill the reservoir with water.
Countertop systems usually need attaching a diverter valve to your faucet and connecting it to the filtration unit.
Under-Sink Systems
Installing an under-sink alkaline water filter can be more complex:
- Turn off the water supply to the sink.
- Install a dedicated faucet for your filtered water if required.
- Connect the filter system to your cold water line.
- Install any remineralization or alkalinization cartridges.
- Mount the system securely under the sink.
- Turn the water supply back on and check for leaks.
- Flush the system thoroughly before use.
If you’re not comfortable with plumbing work, it’s best to hire a professional for under-sink system installation.
Whole House Systems
Whole house alkaline water filter installation is the most complex and typically needs professional help. The process involves:
- Shutting off the main water supply to your home.
- Cutting into the main water line to install the filtration system.
- Installing a bypass valve for maintenance purposes.
- Connecting the system to your home’s electrical supply if it needs power.

Maintenance and Upkeep
Proper maintenance is crucial for the longevity and effectiveness of your alkaline water filter. Here are some key maintenance tasks:
Regular Filter Changes
The most critical aspect of maintenance is replacing filters on schedule. Depending on your system, this could be every few months or once a year.
Many modern systems come with indicators to let you know when it’s time for a change, but it’s good to keep track yourself as well.
Create a maintenance log to record filter changes and set reminders for future replacements. Using expired filters can lead to reduced water quality and potentially introduce contaminants back into your water.
Cleaning the System
Regular cleaning helps prevent the buildup of minerals and bacteria:
- For pitcher and countertop models, wash the components weekly with mild soap and water.
- Under-sink and whole house systems may need periodic sanitization. Follow the manufacturer’s instructions carefully.
- Clean the dispensing faucet or spout regularly to prevent contamination.
Water Quality Testing
Periodically test your filtered water to confirm the system is working correctly:
- Use pH test strips to check if the water is within the desired alkaline range.
- Consider having your water professionally tested annually to check for any contaminants that might be slipping through.
System Inspection
Regularly inspect your system for signs of wear or damage:
- Check for leaks around connections and fittings.
- Look for any unusual noises or changes in water flow, which could show problems.
