Do you really know what’s in your tap water? If you don’t know, you can read this article. Or you can test your water to find out the answer. The fact is that our water contains many different types of contaminants. Therefore, no matter you need water to drink, cook or water your plants, you’d better purify it before using. Here, we will talk about several effective ways to purify our tap water.

Many contaminants are caused by our local water treatment companies. Mostly, chlorine is used to pretreat the water, so that both virus and bacteria are killed to the utmost extent. And then tap water will be dechlorinated. However, this process leaves many by-products that are harmful to both our environment and heath. These contaminants include phosphates, nitrates and silicates which may lead to algae blooms, and heavy metal like iron and copper that may be harmful to reef animals.

Basic Activated Carbon Filters

This type of water filters is good enough for high quality tap water and carbon filters can improve the taste and smell of your tap water. They also can eliminate chlorine, as well as other pollutants. I bought a PUR water filter pitcher and it gives me enough water to brew tea or drink. On the market, many other brands are also good, like Brita, Culligan etc. However, we should know carbon filters have their limits. There are many contaminants they cannot remove. For example, they cannot remove fluoride from our water. You can test your tap water and the results will show what types of pollutants are in your water.


Distilled water is regarded as the purest water in the world. At home, we can use a home or countertop water distiller to make distilled for drinking or cooking. Buying one distiller may cost several hundred of dollars, but it can save more money for you because you don’t need to buy bottled water any more. The distillation process can separate most impurities in our water, like chemicals, heavy meats, viruses and bacteria. However, a home distiller only offers you about 1 gallon of clean water in 4 hours. If you need a large amount of pure water, this method is not the best.

Reverse osmosis

If you are looking for the most efficient way to purify your tap water, you can choose a RO system. Most of them are installed under the sink. Therefore, most under sink water filters are reverse osmosis systems. Although each one can cost you about from $200 to $500, it can give you a large amount of clean filtered water for drinking, cooking or even washing. It is able to pay for itself very quickly. As almost the most effective water filtration systems, they are able to remove various kinds of pollutants in our water, like harmful chemicals, heavy metals (lead, mercury, etc.), bacteria, etc.
