Alkaline Water Benefits to Your Body & Life

The gastrointestinal symptom improvement effect of alkaline ionized water has been approved under the Japan Pharmaceutical and Medical Device Act (PMD Act). Drinking about 0.5 to 1 L of the water a day can be expected to alleviate gastrointestinal symptoms. It’s recommended to start with water that has a pH of 8.5 until you gradually become used to it.

It efficiently extracts glutamic acid umami (savoury taste) components from food to help make your dishes more flavourful.

Alkaline ionized water also effectively works to remove the astringent taste from foods such as spinach. Water of pH 10 is not suitable for drinking.

Acidic water of pH 3.0 helps effectively wash out coffee, tea and other stains from tableware.

Panasonic’s water purification technology has been shaped over 60 years of dedicated refinement, blending a spirit of reverence for water with the trusted craftsmanship of Japanese manufacturing.
Its journey extends far beyond Japan. What we’ve always valued most is to truly understand the water of each land. We’ve surveyed water quality in more than 1,000 regions worldwide and used those insights to develop solutions that are suited to local needs.
Through highly meticulous cutting-edge purification technology and uncompromising product quality, Panasonic delivers healthy, delicious, and safe water to people around the globe.

Many communities still relied on well water—an era when “every household had to consider the safety of their water."

In 1966, Panasonic launched a well water purifier—a device that drew up and purified water directly from wells—marking the starting point of home water purification. Since then, we’ve continued delivering the technology to secure safe water.

As the tap water supply became more stable, new concerns emerged— particularly trihalomethanes and strong smell or taste.

In 1983, Panasonic launched its first faucet-mounted water purifier in Japan— moving water purification into something that could be done in people’s homes at their kitchen faucets.

Water became something that people actively chose with heightened awareness of water quality based on taste, safety, and health concerns.

In 1993, Panasonic introduced an alkaline ionizer to meet rising demand for alkaline ionized water.

Our overseas expansion began in 1997 with Taiwan, chosen for its pressing water quality issues and our established relationship with a local distributor. Building on that brand trust, we then expanded into Malaysia and Vietnam. In regions with a background in traditional Eastern medicine, growing interest in alkaline ionized water also worked in our favor.

As the number of substances water purifiers were able to remove increased, consumers began comparing products based on measurable performance and questioning whether claims of safety and effectiveness could be trusted. At the same time, against the backdrop of droughts, water outages, and the growing habit of keeping bottled water at home, a new idea spread around managing water supply, not just choosing water.

We enhanced cartridge performance and focused on communicating those improvements clearly in Japan. In the late 2000s, we introduced high performance alkaline ionizers and our first pitcher style water purifier, supporting a diverse range of household needs.

Disasters and large-scale water service interruptions, along with rising environmental awareness made securing a stable supply of water for drinking and cooking a realistic concern. Ease of use and long-term usability became reasons for people choosing water purifiers.

We launched horizontal storage pitcher purifiers and cooking water softeners in 2010–2011, offering solutions tailored to how different households use water.

People around the world began spending more time at home. Awareness of water quality at home—such as issues of PFAS—has grown, and new demand for comprehensive household water management is expanding.

In 2023, cumulative sales of Panasonic Alkaline Ionizer surpassed three million units.

We remain committed to our priority of “ensuring that every family can use water at home with peace of mind, no matter the circumstances.” and continue advancing water related technologies to support people’s lives around the world.
