7 Signs You Need A Water Deionizer System At Home

Deionized water is also called demineralized water or soft water. Before undergoing the deionizing system, it’s called hard water. Deionized water has gained popularity in recent years. Many at-home deionizing systems have been developed to convince homeowners to switch to using deionized water at home. 

Deionized water is water in its purest form, meaning all ions in the water are removed. The city water you use contains positively charged ions called cations, such as calcium, magnesium, iron, and sodium. It also contains anions, which are negatively charged ions such as chlorides, sulfates, nitrates, and silica.  

The deionizing system has an ion exchanger resin that replaces undesirable cations and anions with hydrogen and hydroxyl to form pure water. 

Deionized water is essential in the medical field as they need the purest form of water to clean equipment and tools in the hospital before a procedure. It’s also critical to manufacture medicines since deionized water assumes the chemistry of whatever product is added to it. 

So, you might be asking yourself if you need a water deionizer at home. Here are the signs to tell you that you do:

1. If You Always Have Dry Hair

Hard water has high concentrations of hard minerals like calcium and magnesium, which could have harmful effects on your hair. The minerals could build up on your scalp. Even if you feel you have lathered and rinsed many times, you still sense a slightly slippery feeling on your hands. Eventually, your hair will appear limp and dull. 

Meanwhile, if you have color-treated hair, you’ll notice that the color doesn’t stay longer than it should and fades quite quickly. As a result, your hair needs to be dyed more frequently, which makes salon visits pretty expensive. 

Some also shared that hair loss has become an occurrence, and hair strands keep falling, resulting in thinner hair

2. If You Suffer From Dry Skin

The minerals in hard water can affect the natural pH balance of your skin. Most of the mineral residue left from rinsing can absorb most of your skin’s moisture and dry it out. Furthermore, if you have sensitive skin and suffer from conditions like eczema and psoriasis, dry skin could aggravate this condition.

Deionized water will take care of your skin, and its purified form won’t harm your skin’s natural pH.

3. When There’s Scaling On Your Appliances And Pipes

Scaling is the build-up of chemicals in pipes, faucets, dishwashers, washing machines, and coffee makers. Aside from being an eyesore, this scaling could lead to appliance breakdown and huge expenses. 

Since the scale could build up unknowingly, the equipment might stop functioning when you need it, resulting in headaches and a loss of efficiency at home. With a deionizing system at home, your appliances and pipes will have a longer life. 

4. When Your Clothes Fade Quickly

The minerals in hard water can cause your clothes to fray on the edges, fade, and get easily worn out. Because of this, you might need to buy clothes more frequently for your family so they’ll look more presentable when going out. 

Deionized water will take care of your clothes and preserve their quality, so you won’t need to buy new clothes regularly. 

5. If You’re Tired Of Stain Marks on Glasses And Plates

Dishes and glasses coming out of a dishwasher are expected to be crystal clear and squeaky to the touch. Hard water causes stain marks on glasses that won’t fade even if you keep on scrubbing and washing them. 

You’ll be wasting your time removing these marks since the detergent reacts with the hard water. Consequently, this reaction makes your glasses look cloudy which is unappealing, especially when you have guests over.

6. If You Experience Low Water Pressure

Minerals in hard water can leave residue on pipes. Eventually, the build-up can lead to clogged and obstructed pipes affecting the water pressure in your home. Shifting to deionized water will prevent this since the system will soften the water and remove the minerals.

7. If You Have Fish Aquariums At Home

Deionized or demineralized water is said to be the best for fish tanks. Depending on the species of fish you’re caring for, you need deionized water and calcium-based rocks to increase the alkalinity of the water in the tank. 


Deionized water has many incredible benefits. However, when deionized water circulates through your body, it may possibly take minerals from your cells and flush them out. Therefore, it’s not recommended to drink it regularly since it attracts minerals.
