Benefits of Drinking Ionized Water
People usually tend to overlook the quality of the water they drink. Ideally, drinking water should be free from contaminants, but another thing to keep in mind is the water’s alkalinity.
Most systems have titanium or platinum plates, which exchange ions with the water and make it more alkaline. It directly affects water pH value, and through the process, the water also gets purified. Additionally, most systems allow you to manually choose the level of alkalinity, which is very useful.
Ionized water provides numerous benefits, and it tastes better than regular water.
Take a Look At Our Buyer’s Guide
Water ionizers make your tap water more alkaline, and therefore better-tasting. If you never bought a water ionizer before, you might find it somehow tricky. There are multiple things to consider, but filter efficiency is the most important.
The Filter Efficiency
The filter quality directly affects the unit’s ability to remove contaminants. That’s why having the right filter is crucial. Most units come with built-in filters that significantly reduce lead, chlorine, and various contaminants.
However, the efficiency of a filter varies from model to model. The best units should be able to remove contaminants regardless of water pressure. That’s why some systems are excellent for well water, too.
The lifespan of the filter is another thing to keep in mind. No matter which unit you buy, sooner or later, the filter will need to be replaced. Depending on the quality, the filter can last up to six months, or even up to a year. Note that investing in a better filter reduces your costs in the long term.
Additionally, the factor that affects the filter’s lifespan is water contamination. If your water has lots of contaminants, the unit will get clogged more quickly and require frequent filter replacement.
Installation Instructions
Installation is actually very simple. You don’t need a plumber, and also, you don’t need any DIY experience. Of course, the process might vary between units, but it’s all very similar. All you need is a plumber’s tape, wrench, screwdriver, adapter, and a faucet diverter, which is always included in the package.
First, you need to find the best place for the unit. You should install it somewhere near the kitchen sink, so make sure that the area is clear and that there is enough permanent space for the unit.
Then, you should turn off the water supply using the lever underneath the sink. It will prevent pressure build-up in pipes during installation. Next, you need to connect the faucet diverter to your sink. It might happen that the size of the thread doesn’t match the faucet, in which case you would need to buy an adapter.
Now you need to add the connections. Take the metal tube and connect it to the ionizer. Then, remove the aerator from the faucet, and wrap the tape around the inlet. Take the plastic hose and attach one end to the inlet, and the other to the faucet diverter. The last hose should be connected to the bottom of the unit.
In the end, connect the unit to the power source and turn the water on. Most probably, your ionizer will come assembled, so you won’t have to assemble the plates or the filter. If that’s not the case, don’t worry – assembly is also very simple and straightforward. Although the installation process might look complicated now, it will be much simpler when you have the device in front of you.
Unit Cleaning
Like all home appliances, every water ionizer needs cleaning now and then. But how to decide when to clean it? Here are some obvious signs:
- If the unit shuts off during the electrolysis process, it means that your ionizer needs cleaning. Basically, the unit knows that it won’t be able to do the required task, probably because of the sediment build-up.
- If there is a drop in the alkalinity level of your water. The pH of your water should be between 8 or 9, but if it’s lower, it means that the unit is not working efficiently as it should. Also, if your water tastes strange, it might an indicator of changes in water alkalinity.
- If your water flow becomes slower, it means that sediment build-up is too high, preventing the water to flow properly. In some cases, the water might stop flowing completely.
- When the unit works properly, you will see hundreds of tiny hydrogen bubbles. However, if the unit is clogged, there might be no bubbles at all.
- If the water doesn’t produce OPR between -200 and -400, the system is most probably clogged. In some cases, you might even notice the limescale build-up in pipes and tubing.
Unit Maintenance
When it comes to unit maintenance, there are some things that you should or shouldn’t do. At first, make sure to replace filters regularly, or it might damage the unit over time. When you remove the filter, make sure to let the water run at least 5 minutes before you install the new one.
Also, you should use a special cleaning cartridge to get rid of mold inside the unit. When it comes to the exterior, be sure to wipe it once a week.
The first and obvious thing you should avoid is to use harsh home cleaners to wipe the exterior. Also, never create your own cleaning protocols. You should strictly follow the guidelines from the documentation. Not doing so might damage the unit and void the warranty.
Now we will talk about other features you should consider in your purchase decision.
- Plates number: the more, the merrier. As you saw from the list above, some of the best water ionizers feature up to 11-12 plates. It means they will perform great at changing your water’s pH and purifying your water.
- pH range: most modern water ionizers allow you to choose the right water pH for your needs.
- Water filtration systems: most water ionizers also filter your water, cleaning it of impurities. Some may not work as well as reverse osmosis filter systems, but if you have mildly contaminated water, they will do a great job.
- Design: it is an important feature, especially if your kitchen has some space/design constraints you need to factor in before adding yet another device. Pick a countertop ionizer or an under-sink one, depending on your needs. Modern ionizers have a slick urban design that matches modern kitchens.
- Warranty: just like with any other home improvement product, the more extended the warranty is, the more peace of mind you will have.
Frequently Asked Questions
How Do Water Ionizers Work?
Water ionizers use electromagnetism (the process of electrolysis) to separate CO2 in tap water from the alkaline minerals in it. Alkaline water machines turn tap water into ionized water with antioxidant potential.
Is Alkaline Water Good for You?
Alkaline water coming from a water ionizer is safe to drink. It went through at least one or two stages of filtration. Alkaline water is mineral water on tap.
Conclusion
Water ionizers are products that you can depend on, that also offer easy, quality maintenance when you need to replace the filters. And while there are a variety of different water filtration methods, we do recommend purchasing a water ionizer as you always know for certain that your water is clean, tasty, and safe to drink.
