Clean water is something we all need every day, but not all water is the same. “What is purified water”? It’s water that’s been through extra steps to strip out almost everything except H₂O itself. It’s the kind of water you can trust for drinking, cooking, or mixing baby formula.
In this guide, you’ll learn what is purified water, how it’s made, how it differs from other waters (like spring, filtered tap, or hydrogen water), and what benefits of drinking purified water or cons of drinking purified water it has. You’ll also get tips on choosing or setting up the right purification system for your home or office.
What Is Purified Water?
What is purified water? It starts as ordinary tap or well water, then goes through special processes to remove nearly all its impurities—things like dirt, chemicals, metals, and germs. After treatment, purified water almost entirely lacks dissolved minerals and contaminants, giving it a very neutral taste.
Because it’s so clean, it’s used not only for drinking but also in hospitals, labs, factories, and anywhere contamination could cause problems. Unlike regular tap water, which may still contain small amounts of chlorine, lead, or tiny organisms, purified water meets strict standards to ensure it’s essentially just water molecules.
The exact methods can vary—some filters use carbon to trap chemicals, others boil and re-condense water, and still others use high pressure to push water through microscopic membranes. The end result is water that’s consistently safe and tastes the same glass after glass.
Benefits of Drinking Purified Water
What is purified water good for? Here are the top benefits of drinking purified water:
Very Clean
Purified water has gone through a special process to remove most of the harmful stuff like dirt, bacteria, viruses, and chemicals. This makes it one of the cleanest forms of water available, especially important if you're worried about pollution, old pipes, or low-quality tap water.
Fresh Taste
Because the impurities and chlorine are removed, purified water tastes very neutral and fresh. There are no weird aftertastes or odors, making it easier and more enjoyable to drink regularly—great if you're someone who struggles to stay hydrated.
Better Hydration
Drinking enough water helps your body in countless ways. It moves nutrients to your cells, helps flush out waste, keeps your skin glowing, supports smooth joint movement, and even helps maintain body temperature. Clean water encourages better hydration habits.
Quicker Absorption
Many athletes report that purified water feels “lighter” and more quickly absorbed by the body. While scientific evidence is limited, some say it helps them recover faster after intense exercise or avoid feeling sluggish.
Protects Appliances
When you use purified water in appliances like kettles, steam irons, and coffee makers, it prevents scale buildup (white mineral deposits). This keeps your devices working longer and more efficiently, saving you money in the long run.
Customize Minerals
Since the purification process removes almost everything, you can choose to add back just the minerals you want, like calcium or magnesium. This not only improves the taste but also allows you to match your health or flavor preferences.
Safe for Babies & Labs
Purified water is ideal for preparing infant formula or mixing medications. Its purity ensures that no unexpected chemicals or microbes interfere, making it the go-to choice for sensitive uses like lab experiments or baby care.
Helps Kidneys
Drinking enough purified water helps your kidneys function better by flushing out waste and excess minerals. This can help prevent painful kidney stones from forming, especially if you live in a hot climate or consume a lot of salt or protein.
Boosts Immunity
Clean water means fewer chances of ingesting bacteria, viruses, or harmful chemicals that can weaken your immune system. Over time, this helps reduce the risk of waterborne illnesses and supports overall immune health.
Cons of Drinking Purified Water
Now that we’ve seen the benefits of drinking purified water, let’s look at some possible downsides—yes, there are cons of drinking purified water too:
Loses Good Minerals
The downside of removing everything is that even the good stuff, like calcium and magnesium, is taken out. These minerals are essential for strong bones, a healthy heart, and proper muscle function. Long-term, missing out on them could impact your health unless they’re added back through food or supplements.
Flat Taste
Without those natural minerals, purified water can taste “flat” or bland. Some people prefer the richer taste of mineral or spring water, which has a slight flavor due to its natural mineral content.
Costly Systems
Installing a high-quality purification system—especially one with reverse osmosis—can be expensive. Units can range from a few hundred to even thousands of dollars. There’s also a cost for installation, replacement filters, and ongoing maintenance.
Filter Maintenance
Purification systems require regular upkeep. If filters aren’t changed on time, they can trap and grow bacteria, which makes the water dangerous again. Neglecting maintenance can lead to poor water quality and potential health risks.
Wastes Water
Reverse osmosis systems are highly effective but also wasteful. For every gallon of purified water they produce, they can discard 3–4 gallons unless you have a more advanced or eco-friendly system. This can be a concern in areas where water conservation is important.
Energy Use
Some purification methods, like distillation or reverse osmosis, use electricity to heat or push water through filters. This can increase your energy bill over time and may not be the most environmentally friendly option.
Plastic Waste
If you rely on bottled purified water, you're adding to the global plastic problem. Most plastic bottles aren’t recycled properly and end up in landfills or oceans, harming wildlife and the environment.
Slight Acidity
Extremely pure water can be a little acidic (pH below 7) because it lacks natural buffers like minerals. Over time, this could slightly affect your body’s acid-alkaline balance, especially if you don’t get minerals from food or supplements. Adding a small pinch of sea salt or a mineral mix can help balance it out.
Purified Water vs. Hydrogen Water: What’s the Difference?
What is purified water, and how is it different from hydrogen water? Purified Water is regular water that has been cleaned to remove almost all impurities—like dirt, bacteria, chlorine, heavy metals, and other chemicals. It’s great for hydration, safety, and taste, especially if your tap water isn’t the best. Purified water is the clean slate of the hydration world: clear, odor-free, and neutral.
Hydrogen water starts with clean water and infuses it with extra hydrogen gas—adding potential antioxidant and recovery benefits without changing taste.
Why switch? Hydrogen water may help reduce inflammation, boost mental clarity, and improve post-workout recovery. A HydroWata Hydrogen Water Bottle makes it easy—just fill with purified water or tap, and you’re good to go.
Why People Are Switching to Hydrogen Water
Antioxidant Power
Hydrogen molecules may act as powerful antioxidants. That means they can help fight free radicals in your body, which are unstable molecules linked to aging, inflammation, and many chronic diseases. This may help reduce oxidative stress in the body over time.
Supports Recovery and Energy
Some athletes and fitness lovers use hydrogen water to reduce muscle fatigue and soreness after workouts. Early studies suggest that it may help your body recover faster by reducing inflammation and supporting cellular repair.
Brain Health and Focus
Because hydrogen is so small, it can cross into cells and even the brain more easily than other antioxidants. Some people report better mental clarity and focus after switching to hydrogen water.
Gut Health and Inflammation
Hydrogen water may support a healthy gut by reducing low-level inflammation and promoting better digestion. Though research is still ongoing, the early results are promising.
Easy to Use Anytime
You don’t need special water—just a HydroWata Hydrogen Water Bottle or a similar device. It works by electrolyzing the water you pour in (purified or tap), adding hydrogen gas within minutes. You get all the benefits without changing your routine or dealing with odd tastes.
Should You Switch?
If you're already drinking purified water for health and safety, adding hydrogen is a simple next step that might offer extra wellness perks—especially if you’re active, health-conscious, or dealing with inflammation or fatigue. It’s safe, tasteless, and increasingly popular among people who want more out of their hydration.
How Do You Make Purified Water?
What is purified water made from? Purified water is made by removing impurities like dirt, bacteria, chemicals, and dissolved salts from regular water. There are many ways to do this, depending on whether you're at home or in a commercial setting. Let’s break it down:
At Home: Simple Methods You Can Use
Pitcher Filters
This is one of the easiest and most affordable ways to purify water. You simply pour tap water into the top of a pitcher. As gravity pulls the water down, it passes through layers of activated carbon and fine mesh that trap chlorine, metals, and some other contaminants.
Tip: Change the filter cartridge every 1–2 months to keep it working well.
Under-Sink RO Units (Reverse Osmosis)
These systems are installed under your kitchen sink. Water passes through several stages:
- A sediment filter removes sand and dirt
- A carbon filter removes chlorine and odors
- An RO membrane catches dissolved salts, heavy metals, and more
- A final carbon filter or UV light adds extra polish or kills bacteria
- Purified water comes out through a special faucet.
Tip: Replace filters regularly and sanitize the system every few months.
Countertop Distillers
Pour water into a metal container, plug the distiller in, and it heats the water into steam. The steam cools and condenses into pure water, leaving behind minerals and contaminants.
UV Sterilizer Add-On
This isn’t a full purifier on its own, but it’s a great add-on. UV light kills bacteria and viruses as water flows past it. Use this after a standard filter to add a layer of safety.
Don’t Forget Maintenance!
No matter the method, keeping your system clean is essential. Replace filters on time, sanitize tanks, and check seals to keep germs out and your water pure.
Is It OK to Drink Purified Water?
Yes—absolutely. As long as filters and membranes are kept clean and changed on schedule, purified water is perfectly safe for everyday drinking, cooking, or making baby formula. If you’re concerned about losing minerals, you can add in a pinch of mineral drops or use a system with a re-mineralization stage. Simply put, purified water is one of the purest, most reliable ways to stay hydrated.
Applications of Purified Water
Drinking Water Solutions
Restaurants, offices, and homes use pitchers, under-sink systems, or coolers filled from RO tanks for reliable, great-tasting water.
