Why Is It Important to Filter Water?

Learn about the importance of filtering water and how it can help you improve your health, support the environment, and save money among other benefits.

Water is an essential part of human life. Not only does it hydrate your body and support digestion, but it also helps regulate your body’s temperature and eliminate waste products. In fact, the average person’s body is 60% water! Every cell, tissue, and organ in your body needs water to function, as water aids in transporting nutrients and oxygen to cells, lubricates joints, protects sensitive tissues, and plays a crucial role in maintaining your overall bodily functions.

That’s why you need to make sure the water you consume is clean and safe. Unfortunately, the water that comes out of our taps often contains many contaminants that can impact the taste of your water or even pose serious health risks. These contaminants can include bacteria, viruses, heavy metals, pesticides, and industrial pollutants, all of which can have adverse effects on your health. Filtering your water can help remove these substances, and in this post, we’ll discuss the importance of water filtration.

What is water filtration?

Water filtration is the process of removing or reducing impurities and contaminants from water, making it safer and cleaner for consumption, cooking, and other uses. This essential process can address various impurities including sediments, bacteria, heavy metals, and chemicals. Filtration methods range from physical barriers, such as activated carbon filters that adsorb impurities, to chemical processes like chlorination and ultraviolet treatment that neutralize harmful organisms. Some filtration systems use a combination of these methods to tackle a broad spectrum of contaminants, ensuring the water meets health and taste standards.

Why is water filtration important?

Boiling water was once considered sufficient to kill germs and bacteria found in water. However, modern contaminants like pesticides and other chemicals are entering our water supplies and may still remain in the water after boiling. This can potentially lead to illnesses and diseases like cholera, diarrhea, and gastrointestinal infections. As a result, water filtration is more important than ever.

Not only can water filters remove harmful contaminants like arsenic, rust, sediment, lead, mercury, chlorine, iron, scale, and disinfectant byproducts, but they can also ensure your water maintains essential minerals like calcium, magnesium, zinc, and fluoride. However, a water filter won’t just benefit your health. It can also affect the quality of your water, making it taste, look, and smell better.

If you rely on well water, which isn’t tested or treated by any regulatory body, water filtration is an absolute necessity. Even if you have city-treated water coming from your tap, it can still be contaminated. Not only can some contaminants slip through the treatment process, but the water may even pick up additional contaminants from the pipes leading to and within your home. What’s more, if your city uses a chemical-based water filtration technique, your water may still contain traces of those chemicals.

Additionally, even if your tap water is below the legal maximum level of allowable contaminants, that doesn’t necessarily mean your water is 100% safe. Over time, we’ve seen new research come out that leads to stricter standards about which contaminants are regulated and at what levels.

Benefits of filtering your water

Filtering water in your home offers several benefits, including:

  • Improved water safety: One of the most important benefits of filtering your water is that it can remove harmful contaminants from the water you drink and cook with, reducing your risk of waterborne diseases and long-term health issues.
  • Enhanced water taste, appearance, and smell: Filtering your water can also improve its taste, appearance, and smell, as it removes substances like chlorine and sulfur. At the same time, water filters can leave healthy mineral deposits that result in drinking water with a healthy pH balance and a better overall taste.
  • Healthier hair and skin: Using a water filtration system removes the harsh chemicals and impurities that can easily dry out and damage your hair and skin.
  • Reduced wear and tear on clothes: Similarly, a water filter removes sediment as well as harsh chemicals. This can reduce the wear and tear on your clothes, allowing them to look better and last longer after each wash.
  • Protection against vaporized contaminants: Some contaminants like chlorine can become even more dangerous when vaporized as steam while you shower, so a water filter can help prevent the threat by reducing the contaminant’s presence before it gets to that point.
  • Help the environment by switching from bottles: By using a home water filtration system, you can significantly reduce your reliance on single-use plastic bottles that contribute to environmental pollution. Instead, you can filter water at home and bring it with you in a reusable bottle.
  • Cost savings: If you drink the recommended 8 glasses of water per day, you’ll spend $1,400 on bottled water but only $0.49 on tap. Although a filter requires an initial investment and replacements over time, it can help you save money in the long run.
