How Does Water Filters Work – Types & Methods

You can drink filtered water in the current polluted world, yes, you heard right. We are going to tell you today how does water filter work. In the current polluted world, finding fresh daily life necessities has becomes extremely very difficult. In our daily life necessities, as we know that, water is on the top of the basic need of everyone lives.

To drink purify or clean water is everyone’s right Thus, how we can drink purified water in the pollutant world. There are many types of water filters available in the market which clean water and make it able to drink. But in the abundance of water filter devices which one is perfect for us, and how does water filter work?

These questions commonly arise when people think to buy a water filter. So today, our agenda is to make you understand how does a water filter works? what things you should check while purchasing a water filter. If you are thinking to buy a water filter then you must know actually how does a water filter works? In this article, we will answer all of your questions about How Does water filters work.

Filter Water and Body:

Our body contains 25% of water. If we say around two-third of your body is H2O, then it will be not wrong. Else, if you are 8 to 12 years old then 75 percent of your body contains water. Even if you think your bones are strong, then let me tell you they are not completely solid, they also contain 25 percent of water. So, as a sum up, our body needs water between 2.0 litter to 2.4 litter on daily basis. It is necessary to drink refined water, and understand how does water filter works.

Water is so important to our lives, but in the current era obtaining refined, clean, purified, pure, and tasty water has become entirely difficult. Polluted water contains many substances including chemicals, microorganisms, or bacteria that harm our bodies. Moreover, sometimes using contaminated water long time caused, cancer, ulcer, and abdominal diseases, and infections, etc. These are some obvious reasons that compel people to think about buying a water filter. How do water filters work and how harmful stances they eliminate from water are necessary to understand this process before purchasing? Let us understand how does a water filter works?

How does water filter work?

There are many types of water filters available in the market such as mechanical filters, absorption filters, sequestration filters, Ion Exchange Filters, and Reverse Osmosis Filters, and many more, etc.

Now, what is the basic principle of all water filter tools use to do filtration? let us understand step by step.

Water Filtration is the process of removing or reducing the contaminated material such as substances, bacteria, viruses, parasites, fungi, particles, and harmful chemicals from the water. Furthermore, as well remove undesirable particles and make them clean, pure, and refined for a drink. To remove all the contaminated materials from the waters usually have to takes five-step. These five steps are: in how does water filter works,

  • Sediment Filter
  • Mechanical Filter
  • Mineral Filter
  • Chemical Filter
  • Bacterial Filter

Types of Water Filters

Sediment Filter: 

Sediment Filters are specially designed to solids particles from contaminated water. These sloid particles are knowns as sediment, turbidity, and particulate. A sediment filter is a thin net that grabs all the unwanted solids particles, dirt particles and passes the clean, refined, and pure water to the next layers. As water flow in the sediment filter and net grabs all the undesired particles. Sediment filters play an important role in how does a water filter works.

Mechanical Filtration:

All hard particles like sand, silt, loose scale, organic matter, and clay are removed by the mechanical filter. Contaminated water is filtered using a mesh filter, also known as a cartridge filter, which captures all of the hard particles. This is how does a water filter work in mechanical filtration. Clean water should be pumped to the next layer. Because mechanical filtration does not remove dissolved chemicals and other very small particles, it is often used in conjunction with other water filter tools.

Chemical Filter:

Chemical filters are one of the most effective ways to get rid of parasites, bacteria, viruses, and microbes. To clean the tainted water, chlorine is utilized. It is a reliable method of water purification that eliminates all dangerous contaminants. Water is cleansed and can be consumed at home using this procedure. Chlorine can be purified in a variety of ways, including using chlorine tablets to purify polluted water or using chlorine liquid to purify the same water. This is how does water filters work in a chemical filter work. Besides, chlorine liquid and tablets you can be used at home to purify water at home.

Bacterial Filter:

Bacteria are a frequent substance present in water. Because the water comes from a variety of sources, including streams, tunnels, and subterranean aquifers. As a result, bacteria in the water are a widespread problem. The bacterial filter is used to eliminate bacteria. To cleanse the water and make it drinkable, this filtration process uses chlorination, ozonation, and UV techniques.

Basic Steps on how does a water filter work:

These five steps are involved in water filtration. There are membrane layers in water filters when contaminated water is put inside the filter. These membranes start their work and store the virus or bacteria and let the water goes down. The water filters are the same as a big water jar, we have to put water from the top. Then water moves layer by layer and each layer does their work. when water passes from the first layer, membranes remove the bacteria or virus, then there is 2nd layer, known as nanolayers that remove parasites, chemicals, etc. This is basic principle and steps of how does a water filter work.

Other Commonly used water Filtration Tools:

There are many others water filtration methods available in the markets that can be used and commonly are in use. Let us discuss all of these in a detail:

Activated Carbon or AC Water Filter Method:

How does a water filter work in activated carbon? Usually, these filters come with carbon blocks.  Through activated carbon, 70 percent of unhealthy material can be removed from contaminated water. This is the most commonly used method and very effective. It mostly uses if contaminated water contains only fungi and chemicals.

Reverse Osmosis or RO Water Filter Method:

This method also play important role in how does water filter work. This is a very effective way to remove all the harmful substances such as, parasites, bacteria, and hard chemicals that activated carbon does not remove. Mostly it works with Activated Carbon or Ion Exchange.

How does water filters work

Ion Exchange or IX Water Filter Method: 

Water might be tough to resolve in some cases because it is hard by nature. Many diseases, such as abdominal pain and motion, are caused by this type of water. So, it is necessary to learn how does filter water work. For the hardness of water, ion exchange is particularly effective. Because it removes individual mixtures depending on their ionic charges while leaving essential or nontoxic minerals in solution.

Distillation Water Filter Method:

In the age of water filtration, this is distillation, the oldest method. This is where water filtration begins. It’s quite straightforward. To eliminate harmless minerals from water, it must first be boiled. The water vapor then rises to a condenser, where cooling water reduces the temperature, compounding, assembling, and storing the vapor. The majority of pollutants remain in the liquid phase vessel. Typically, distilled water has a bad flavor. Distillation was the most typical approach for explaining how a water filter works. However, it is no longer widely used because water contains many dangerous compounds that cannot be eliminated only through distillation.

Ultraviolet Light Filters Method:

It’s the most efficient way to get rid of microorganisms from water. Although the bacteria are invisible to the naked eye, it is exceedingly destructive to the human body. It increases the risk of infection. As a result, it is vital to understand how ultraviolet light works in water filters. It removes all visible creatures from the water as it passes through. It’s as straightforward as that. Other forms of common pollutants, however, are not removed by this method. As a result, it’s frequently utilized in conjunction with activated carbon or reverse osmosis.


A precious resource on earth is water. Life on earth is not possible without water. Our body contains two-thirds percent of Water. In order to stay healthy, drinking filtered water is essential.

However, as we know, water travels along streams, tunnels, or unground aquifers, and lakes and their bacteria has been added into water.

Additionally, factories and companies dispose of chemical waste into steams, tunnels, or lakes, making the water unusable. Now, using it for household purposes or as a drink could lead to serious illnesses like cancer, diabetes, liver problems, Hepatitis A/B, heart issues, etc.

To solve the problem of contaminated water, the water filtration process comes into play. Hence, we have discussed, “How does water filters work”. There are many ways to filter water at home, including distillation, UV light, Ion Exchange, and chlorine.

To conclude, we recommend that you have to check the water in your house first, before purchasing any water filter tools. You can get a detailed report from laboratories, that showing you what harmful substances are present in your water. After that, you can choose an appropriate water filter tool based on the contaminants in your water.
