The goal of water purification is to provide access to clean and healthy water. Clean water, free from any contamination, is essential for humans, and by using a water purification system, you will ensure that you always have safe, stable water, free from unpleasant tastes and odors.
Although access to clean drinking water is recognized as a human right, there are still areas that face challenges, and this is not limited to less developed areas. Even in some parts of the USA, there are concerns about this. In this regard, water purification systems can be of great help. In this article, we will try to discuss the purpose of water purification in detail.
Definition of drinking water
Drinking water is a refreshing water whose quality meets approved standards and whose consumption does not lead to adverse effects on the human body in the short or long term.
Another definition: Drinking water is water of suitable quality, the consumption of which does not have a negative effect on the functioning of the human body, either in the short or long term.
In most parts of the world, safe and quality drinking water is not easily and inexpensively available to the public. Most people in these areas use water that contains impurities or harmful substances. These people may be exposed to some diseases such as diarrhea, typhoid, cholera, etc.
In some countries, drinking water is delivered to homes through separate pipes from non-drinking water pipes.
Research results show that, today, groundwater aquifers, especially in large and densely populated cities around the world, have many problems, which are caused by:
- Infiltration of industrial wastewater;
- Existence of absorption wells for the disposal of human wastewater;
- Excessive use of chemical detergents and cleaners;
- Infiltration of chemical and animal fertilizers into the depths of the earth.
The water of rivers, wells, lakes, and even water from melting ice and snow contains many industrial pollutants that we humans have caused.
What can you find in tap water?
🦠 Bacteria
Unfortunately, industrial purification systems sometimes simply fail to cope with their duties, and the probability of pipe breaks is far from minimal. Such “guests” in water are dangerous because they can cause dozens of different diseases and generally undermine the immune system.
⚗️ Chemical impurities
They get into our taps with wastewater. Analysis of liquid poured from the tap can show the content of gasoline, fuels and lubricants, detergents and even carcinogens.
🛑 Heavy metals
They also get into water bodies with groundwater and wastewater. The consequences of drinking “life-giving” moisture with toxic heavy metals certainly cannot be called beneficial for the human body.
🛠️ Rust
In our country, metal water pipes are mostly old, and here is the result: iron oxide in the water remains in the form of very small particles. It is rust that sometimes causes kidney stones in people.
💧 Magnesium and calcium salts
They are the ones that cause the whitish sediment to appear on the walls of the kettle. Hard water, unfortunately, does not add to health either.
The purpose of water purification
Due to the many dangers that impure water poses, the demand for water purification is increasing day by day. On the other hand, surface water resources, which are the water behind the dams, are not sufficient and their amount is decreasing day by day because we are struggling with environmental pollution, climate change and rapid population growth. As a result, we are forced to use groundwater resources that are more polluted. These cases clearly show the purpose of water purification.
In the not-so-distant past, people boiled water to kill germs and bacteria to ensure its safety, but boiling also removes essential minerals and salts. Today, things have changed, with newer and more diverse contaminants added to water sources, such as pesticides, herbicides, and other dangerous chemicals. This is where the importance of water purification and purification options comes into play to keep your drinking water safe and healthy.
Equipped with multiple filters, water purifiers remove harmful bacteria and chemicals that can cause illness and impair your health. Here are some of the reasons why using a water purifier is essential to get a comprehensive view of the purpose of water purification.
- Remove harmful contaminants such as bacteria, viruses, parasites, and chemicals.
- Ensure safe drinking water for human consumption.
- Improve taste, odor, and clarity of water.
- Prevent waterborne diseases like cholera, dysentery, and typhoid.
- Protect plumbing systems by reducing scale and sediment buildup.
- Support healthy skin and hair by removing harsh minerals and chlorine.
- Enhance cooking and food preparation with cleaner water.
- Increase the lifespan of household appliances that use water, like dishwashers and washing machines.
- Promote environmental sustainability by reducing reliance on bottled water.
- Ensure compliance with health and safety standards in residential, commercial, and industrial settings.
Water Purifier - Purpose, Types, benefits and buying guides
What is a water purifier?
Water purifiers refer to systems that use the best purification methods to separate suspended particles, contaminants, and chemical pollutants. In fact, any type of system that removes any amount of these particles and contaminants in water is called a water purifier. This device removes approximately 90 percent of contaminants, including microbes, sediment, pathogens, chlorine, and minerals, resulting in safe water that is safe to drink.
Water purification is performed by small household systems, or whole house water filtration systems as well as larger systems such as industrial devices and municipal water treatment plants.
How a water purifier works
Due to its molecular structure, the element of water dissolves many harmful substances as it circulates in nature. When water enters municipal water purification systems, a large part of these contaminants and impurities are removed from the water. However, not all of these substances are removed from the water and, along its path, it absorbs some impurities for various reasons, including old and rusty plumbing systems.
To remove these contaminants, which sometimes increase the acidity of the water, you must use water desalination devices. Water desalination devices come in different types with different applications, the most common of which is the home water purifier.

✅ There are different types of water purifiers, the most famous and widely used of which are reverse osmosis (RO) water purifiers. To understand how these devices work, we must first understand the function of each filter in this device. Of course, since each water purifier purifies water in 4 to 6 stages, the number of filters in each device is different. In this section, we will explain all the parts and stages of a device.
Types of water purifier filters
Understanding the types of water purifier filters before purchasing a water purifier is very important and will help you gain sufficient information about the function and timing of water purifier filters replacement in order and their periodic service time. Each of these filters is examined below.
1️⃣ Polypropylene filter
This filter resembles compressed cotton placed inside a transparent housing. The function of the polypropylene filter is to remove coarse particles such as mud, sand, pipe rust, and generally suspended particles larger than 5 microns in size.
2️⃣ Granular activated carbon filter
This filter is made from coconut shells and is completely herbal. This filter completely removes chlorine from the water by releasing positive and negative ions. To purchase the original sample of the activated carbon granule filter, we recommend that you place your order at the Aquaguard Solutions.
3️⃣ Carbon block filter
This filter is the last stage of the three pre-filters, which is responsible for removing chloramines, which are byproducts of chlorine, from the water. Another function of the carbon block filter is to purify water from coarse salts passed through the polypropylene filter. This prevents debris from filling up the membrane layers and extends their useful life. For information on the price of a water filter, contact our experts at Aquaguard Solutions.
4️⃣ Reverse osmosis membrane filter
This filter is the heart of the water purifier and removes harmful salts in drinking water that are up to 0.0001 microns in size, thus reducing water hardness to standard levels. Arsenic, aluminum, nitrate, fluoride, nitrate and iron rust are among the most important particles that are removed from water by the reverse osmosis membrane filter.
5️⃣ Linear carbon post filter
This filter converts salt water into fresh water and significantly improves its taste, color, and smell. You should note that coconut shells are also used to make the linear post-carbon filter. If after a while, you feel bitterness in the water coming out of your home water purifier, it is likely that your post-carbon filter is saturated and you need to replace it. Visit our site to buy all kinds of industrial and home water purifier filters.
6️⃣ Mineral filter
After purifying the water, this filter adds beneficial minerals such as magnesium, calcium, sodium, and bicarbonate to the drinking water, and these beneficial minerals are absorbed by the body when you drink the water. Another function of the mineralizing filter is to reduce the hardness of the water, which has a significant impact on its quality.
7️⃣ Alkaline filter
In the seventh stage of water purification, an alkaline ionized alkalizing filter is used, which brings the pH of the water to 7.5 to 9. This is the best level of alkalinity for daily and continuous human consumption. This filter creates strong anti-cancer or antioxidant properties in the water and is very beneficial.
8️⃣ Antibacterial filter
The antibacterial filter releases negative and positive ions and increases the amount of dissolved oxygen in drinking water. In addition, this filter completely cleans and removes harmful bacteria in the water that passed through previous filters.
Types of water purifiers
💧 Reverse Osmosis (RO) Purifier:
Uses a semi-permeable membrane to remove dissolved salts, heavy metals, and impurities.
☀️ Ultraviolet (UV) Purifier:
Uses UV light to kill bacteria, viruses, and other pathogens without altering the taste.
🧵 Ultrafiltration (UF) Purifier:
Uses a hollow fiber membrane to remove particles, bacteria, and cysts, but not dissolved salts.
🪵 Activated Carbon Purifier:
Uses activated carbon filters to remove chlorine, bad taste, odor, and organic compounds.
⛏️ Sediment Filter:
Removes visible particles like sand, dirt, and rust from water.
⚖️ Gravity-Based Purifier:
Uses gravity and simple filters (like activated carbon or UF) to purify water without electricity.
🔄 Ion Exchange Purifier:
Replaces harmful ions like calcium and magnesium with sodium ions, often used for softening hard water.
🔧 Multi-Stage Purifiers:
Combine two or more purification methods (e.g., RO + UV + UF) for comprehensive purification.
What is the purpose of buying a water purifier?
Do you want to know the purpose of buying a water purifier? In answer, we must say that using this device reduces the amount of unhealthy and contaminated salts in drinking water and increases the PH level of the water. This makes you have healthy and alkaline ionized water that brings many properties to the body. Drinking this water brings many antioxidant or anti-cancer properties to the body, the most important of which are as follows:
👪 Your health and that of your family
Almost 80% of the human body is made up of water. That is why water is one of the most vital elements needed for our body’s health. Doctors recommend that we drink 8 glasses of water a day, or one glass for every 10 kilograms of our body weight. It goes without saying that the healthier, purer and better quality this water is, the greater the vitality, health and function of our body’s organs will be.
🛡️ Preventing diseases caused by drinking contaminated water
Drinking safe water helps prevent diseases caused by contaminated water. One of the common problems caused by unhealthy city water is kidney stones, which are caused by the presence of mud, sand, sediment, and salts larger than 5 microns in the water.
These salts settle in tea cups and boiling water kettles, and the only way to prevent them from entering drinking water is to use a suitable water purifier. Also, the presence of aluminum in drinking water leads to early Alzheimer’s in the long term. This disease is almost incurable, but purifying water from harmful salts minimizes the risk of developing it.
❤️ Reducing the risk of cancer, respiratory problems and heart disease
Chlorine is a substance that is added to municipal tap water and kills bacteria, parasites, viruses and many other dangerous and pathogenic microorganisms. In almost all countries of the world, chlorination is known and used as the most effective and best way to deal with microorganisms in water.
Experts believe that removing chlorine from drinking water when we are going to drink it will significantly reduce the risk of cancer, respiratory problems and heart disease. Home water purifiers are able to remove chlorine from water at the very moment you are going to drink it and give you water free of any impurities.
🧪 Removing chemicals from municipal water
A home water purifier can be very effective in removing chemicals from city water and minimize the risks. Note that these substances can lead to the birth of sick babies and have a negative and irreparable effect on people’s DNA. Buying a home water purifier prevents the occurrence of pre-existing diseases in babies. It also increases the immunity of pregnant women.
🧠 Reducing the risk of Alzheimer’s
Research shows that the presence of aluminum ions in water has a significant relationship with the risk of Alzheimer’s disease. Aluminum is one of the elements that is difficult to eliminate from the body and is deposited in the human brain, causing disorders such as Alzheimer’s.
Home water purifiers using reverse osmosis technology and RO membranes will remove all heavy metals including aluminum, lead, mercury, cadmium, etc. from drinking water.
☣️ Drinking water purification from nitrates
One of the most harmful dissolved substances for humans is nitrate, which, when it enters the body, turns into nitrite and leads to a significant decrease in the amount of oxygen in the person’s blood. This disrupts the body’s nervous system and may cause death in young children.
So that a large number of babies lose their lives at birth and within the first year of their lives due to a decrease in the amount of oxygen in the blood. Accordingly, purifying drinking water from nitrate is one of the most important goals and necessities of purchasing a water purifier.
💧 Reducing the hardness of drinking water
Another important reason to use a water purifier is to reduce the hardness of drinking water. This is important for both human health and the health of the creatures inside the aquarium. The standard water hardness for a freshwater aquarium is a number between 0 and 30, and for a saltwater aquarium it is close to zero, i.e. distilled water. Also, to maintain the health of the human body, this number is between 30 and 90. The best way to separate these particles from our drinking water is by using water purifiers.
☕ Improve the taste of tea, coffee and food
By using a home water purifier, you will have access to a source of healthy, refreshing water, free from any impurities and chemicals, which you can use not only for drinking but also for cooking, washing fruits and vegetables, brewing tea, making coffee, and even watering your houseplants, and see its miraculous effect. There are no limits to the uses of this refreshing and healthy water.
💰 Save time and money
Yes, you got it right. We believe that purifying water is not an expense, but a long-term and profitable investment. Have you noticed that the price of a bottle of mineral water is much more expensive than the price of a bottle of gasoline? This is while in many cases, not only is the quality of bottled water no better than tap water, but sometimes it is worse.
It is clear that most of the money you pay to buy mineral water is actually the cost of its packaging. The same thing that eventually ends up in the trash. A home water purifier is a small factory for producing healthy and hygienic water in your kitchen that produces healthy and hygienic water for your family under your own supervision and control.
Protect your family with the right water purification system
Advice on buying a water purifier
Things to consider in a water purifier buying guide : First, the type of filtration and the number of water filters. A 6-stage reverse osmosis water purifier is quite suitable and sufficient for reducing water hardness and contaminants. However, if you live in an area with a lot of microbial contamination of water, you should use an ultraviolet water purifier, which is often an 8-stage device.
Alkaline water purifiers are also one of the most popular models. This device has a seventh-stage water ionizing filter that gives water anti-cancer properties and alkalizes it. You can get advice from the official dealer and representative to buy any of these models.
💡 Water purifier buying advice will help you buy the best device based on your budget and the type of water pollution in your area
The best price for all types of original home water purifiers is also important, but always prioritize quality and buy a device that is from a reputable brand and make sure that the parts and filters meet international standards and approvals.
Buying a reputable brand of home water purifier will also bring after-sales service and a warranty for the device. For this reason, be sure to buy your home water purifier from reputable dealers to be sure that it is original.
Conclusion
Water should be considered a basic and permanent need for human society. Approximately 80 percent of the human body is made up of water and it plays a significant role in regulating and functioning many body functions. The body’s chemical reactions also require a certain amount of water. If there is no water in the body, parts such as the skin lose their shape and function.
We hope that all people on the planet will have access to safe drinking water in sufficient quantities to significantly improve the health and quality of life of all human societies. Overall, water purification is an investment in your health, the environment, and a smart way to reduce costs such as buying bottled water.
