Is It Safe to Drink Tap Water in Malaysia?

How do You Make Sure You are Drinking Clean Water

Tap water in Malaysia is suitable for individuals’ consumption only when taken from trusted water treatment facilities. Government and commercial organisations such as Air Selangor are responsible for carrying out sufficient tests to ensure that Malaysian water consumption quality is adequately handled. Most of the time, the water supply in Malaysia will undergo testing to successfully fulfill the requirements set by international organisations, such as the World Health Organisation.

Is Malaysia’s Water Clean?

The Ministry of Health (MOH) in Malaysia established guidelines for water treatment, including adding chlorine to the water to eliminate microorganisms. This ensures that impurities and pathogens are removed from the water before the public consumes it. Even though chlorine is added to the water and effectively kills bacteria, the quantities added during water treatment are not harmful to people. These chlorine concentrations are much lower than necessary to make people sick.

It may not be safe to drink water right from the tap. This is reinforced by the fact that different areas in Malaysia may not have a good piping system, which might directly affect the water being supplied to the area. Drinking water thoroughly purified and filtered from bacterial, chemical, and physical impurities is best. Taking the extra precaution of purifying and filtering your water supply will ensure that your drinking water will be safe and healthy.

What is in tap water that is bad?

Tap water contains many impurities and contaminants that are not safe to be consumed by the human body. These harmful substances can damage the body if they enter our system, as they can cause us to contract deadly diseases such as typhoid, dysentery, and cholera.

Contaminants and impurities found in unfiltered tap water can be physical, chemical, or bacterial. This includes viruses, bacteria, minerals, lead, copper, fungi, parasitic worms, organic waste, pesticides, and many more.

How do you make sure you are drinking clean water?

Water kit analysis

It is crucial to take steps to ensure you are drinking water that is safe, clean, and without any harmful substances to prevent yourself from getting sick and contracting severe diseases. One way you can ensure the safety of your drinking water is by using a water analysis kit at home.

A water analysis kit will contain a testing strip that will change colour to indicate whether the water is safe to drink. Another way is to contact the water treatment plant to inquire about their water quality information.

Yet, the most common and easiest step is to drink filtered or purified water. This is because purified and filtered water goes through filters that remove impurities and contaminants before you can drink it.

Filtered water

Water that has undergone filtering using water treatment techniques is referred to as filtered water. Water can be filtered using various methods, including reverse osmosis, activated carbon, ion exchange, distillation, etc. Filtered water may successfully remove dangerous impurities and contaminants from the water while reducing the smell of tap water to make it more pleasant to drink. The home and office water purifier will filter your water to ensure that all the harmful impurities are removed so you can safely consume your water without any worries.

Water purifier

Purified water must undergo several chemical treatments and mechanical filtrations to create clean, drinkable water that everyone can ingest daily. Water’s purification process includes coagulation, sedimentation, filtration, and distillation to ensure that the water does not harbour hazardous substances, such as soil particles, heavy metals, mineral residues, and chemicals. Due to filters like the nano-positive membrane, sediment filter, and activated carbon filter that successfully remove significant pollutants, undesired chemicals, and viruses from the water, a water purifier can effectively purify the water.


Drinking a healthy water supply will help your body regulate its temperature to an average level, protect sensitive tissues, and eliminate waste through perspiration, bowel movements, and urination. You should always drink water free from impurities, as contaminants can destroy your body and render you ill.

We highly recommend using a water purifier in Malaysia to purify your water from all physical, chemical and bacterial impurities. This is to ensure the water we consume will not affect our health and will instead increase our well-being.

The tap water in Malaysia is derived from upstream dams rather than the water table, which absorbs contaminants from the soil. The primary dams providing water to Greater Kuala Lumpur (Klang Valley) are the Klang Gates Dam and Batu Dam.

To enhance chlorine’s disinfection effectiveness, the pH should be below 7. The National Drinking Water Quality Surveillance Programme (NDWQSP) survey found that the pH levels of tap water in 20 chosen regions ranged from 6.70 to 7.99, averaging 7.72. In Malaysia, chlorine is employed in the disinfection process for public water supply.

Based on the official guidelines, tap water in Malaysia is generally deemed safe for consumption as long as there is a sediment and chlorine filter. Nonetheless, a considerable number of Malaysians choose to either filter or boil the water before using it for drinking purposes. The convenient alternative is to use a water purifier at home or office.

As local authorities strive to ensure the safety of drinking water supplies, there remains a possibility of pollutants entering the water. Filters are an additional protective layer, eliminating even minimal traces of bacteria, heavy metals, and pesticides. This results in water that is not only more palatable but also healthier for consumption.

Filtered Water vs Purifier Water vs Boiled Water – Which is Better?

Filtered Water vs Purifier Water vs Boiled Water Which is Better

The human body loses water daily through breathing, sweating, urinating, and bowel motions. About 50% to 70% of an adult human’s body weight is water, the body’s principal chemical constituent. That being stated, water is essential for the survival and health of the human body. One can also refill their body’s water supply by ingesting liquids and meals containing water to function correctly; however, it is best to consume plain water.

As the water supply comes from different sources in Malaysia, it is essential that the water we are drinking is clean and does not contain any impurities. There are different types of water, such as boiled water, filtered water and purified water. This article will discuss these types of water and their advantages and disadvantages.

Boiled water

Water heated to the boiling point of 212 degrees Fahrenheit or 100 degrees Celsius is considered boiled water. Boiled water is water that has undergone the process of boiling, as is a traditional way of removing impurities from water. The boiling process occurs by placing a heat source beneath a container filled with water and letting it rest on the heat source until it bubbles.

The boiled water is then left to cool before individuals can consume it. Water that has been boiled is free from harmful bacteria and viruses that can cause harm to our health; however, boiling does not remove chemical pollutants such as metals, chlorine, salts, and even pesticides.

Advantages & Disadvantages of boiling tap water

Simple to do as it does not require intricate equipmentsTime-consuming as boiling takes several minutes before it is fully boiled.
Kills harmful bacteria and viruses in the waterDoes not remove chemical pollutants such as chlorine, pesticides and metals
Retains essential minerals that are found in tap waterQuantity of water may be reduced as some of the water that is boiled may become vapour

Filtered water

Filtered water is water that goes through filtration using water treatment technologies. Filtered water can effectively remove harmful substances and impurities from the water while also removing the odour of tap water so that it is easier to consume.

Filtered water can undergo different filtration processes, such as reverse osmosis, activated carbon, ion exchange, distillation and other methods. Even though filtered water does go through its own filtration process, it may not be suitable for drinking as the filters cannot fully remove all the impurities that are in the water, which can cause infections in our bodies.

Advantages & Disadvantages of Filtered water

Convenient to use as the filtered water is available on tap to use whenever you need it for cooking or drinkingNeeds to be stored in the refrigerator to avoid recontamination
Removes harmful substances such as bacteria, viruses, chlorine, heavy metals, salts and fluorideFilters need to be maintained and replaced frequently and depending on usage
Environmentally friendly as it reduces plastic wasteFiltration process can only work properly if there is pressure in the water

Purified water

Purified Water

Purified water involves several chemical treatments and mechanical filtrations to produce clean and drinkable water that is safe to consume for all. Purified water does not contain any toxic substances such as soil particles, heavy metals, mineral residues, and chemicals due to the water’s purification process, such as coagulation, sedimentation, filtration, and distillation.

A home and office water purifier can efficiently purify the water due to filters such as a nano-positive membrane, sediment filter, and activated carbon filter that effectively remove large impurities, unwanted chemicals, and viruses from the water.

Advantages & Disadvantages of Purified Water

Eliminates all forms of physical, bacterial and chemical contaminants such as large particles, rust, heavy metals, bacteria, viruses and chlorineRegular maintenance and replacement of filters are needed to remove all the harmful metals and organisms that get stuck on the filter
The quantity of water does not change when it undergoes purification processMay not be able to remove some forms of organic wastes and pesticides
Easy to access the water for the convenience of drinking, making drinks, cooking, and more.Increases energy consumption due to the processes that occur.

Summary (Best Way)

As there are different ways to consume clean water in Malaysia, it is also essential to consider how much water you drink daily. Studies have shown that eight glasses of water may not be enough for an individual. The daily water intake is highly dependent on the individual and their lifestyle. Whether it is boiled water, filtered water, or purified water, it is crucial to have a healthy water supply.

The best way to make sure you are drinking a clean supply of water is to test your drinking water and look out for signs of contamination. In a nutshell, the best water to consume without compromising your health and well-being is purified water. Purified water removes impurities and chemical compounds that are unhealthy for the body, plus it is easier to access clean water using a water purifier in Malaysia.

Filtered water surpasses boiled water. Boiling alone falls short of achieving complete water purification, as it retains harmful contaminants like lead and chlorine.

Although the process of boiling water is efficient in eliminating disease-causing pathogens such as viruses, bacteria, and other microorganisms, it does not ensure the attainment of 100% safe drinking water.

Consuming purified water ensures the presence of essential minerals necessary for optimal bodily function. Purified water effectively eliminates harmful bacteria that could otherwise result in illnesses, stomach discomfort, and nausea. Some of the purified water benefits include assisting in digestion, enhancing athletic performance, detoxifying the body, and contributing to clearer skin.

Nevertheless, the decision of which is better – boiled water vs purified water, should be based on the desired level of purification and the specific contaminants present in the water source.

Should you boil water excessively or reboil it, there is a potential to concentrate specific unwanted chemicals present in the water. Chemicals like nitrates, arsenic, and fluoride are examples of substances that may become more concentrated through prolonged boiling.

It’s crucial to note that boiling water does not eliminate minerals. Inorganic elements such as calcium, magnesium, and sodium maintain stability at elevated temperatures. Therefore, when boiling water, these minerals persist, and their concentration may increase as the water evaporates.

Boiled water can be stored in sanitised, securely sealed containers in the fridge for up to 3 days or at room temperature, away from direct sunlight, for 24 hours.

Drink one glass of water 30 minutes before a meal to help digestion. Remember not to drink too soon before or after a meal as the water will dilute the digestive juices. Drink water an hour after the meal to allow the body to absorb the nutrients.

Water Filter vs. Water Purifier: Comparison 2023

Water Filter vs Water Purifier Comparison

It is well known that frequently consuming water is healthy for our bodies. This is because water makes up roughly 60% of the human body. Water is essential for the body’s cells, tissues, and organs to function. It is advised to drink enough water each day to maintain good health. However, the quality of the water you drink is equally crucial for maintaining your health.

Maintaining access to a clean water supply in Malaysia is crucial since it is vital to our health. Water filters and water purifiers come into play in this situation when it comes to our house water particularly. This article will give you a thorough overview of water filters and purifiers with detailed comparisons and differences between the water filter and water purifier.

What is a water purifier?

What is a Water Purifier

A water purifier serves a similar purpose to a water filter, as both devices aim to eliminate impurities and pollutants from the water. However, a water purifier takes things a step further by destroying biological contaminants and removing minerals such as suspended microbes and particles, excess salts, and viruses while maintaining vital vitamins beneficial for our body as we consume filtered water.

Effectively removing harmful viruses and bacteria while allowing essential minerals to pass through the water, a water purifier is primarily used indoors in spaces like the kitchen, tabletops, or office. This indispensable home and office water purifier ensures a reliable source of clean drinking water for both environments.

Water purifier benefits

There are several benefits to using a water purifier, and these are the main ones:

  1. Removal of toxic substances

Water purifiers effectively remove toxic and harmful substances commonly found in unfiltered water, such as disease-causing microorganisms, dissolved solids, metal impurities and even unhealthy minerals. Without water purification, these harmful substances can cause us to become sick and damage our health.

The best type of water purifier in Malaysia is built with at least four filters for thorough and essential water purification. These four filters are the Sediment Filter, Activated Carbon Filter, Nano-Positive Membrane, and Mineraliser, which effectively remove a range of harmful substances, from rust and sediments to viruses and bacteria.

  1. Environmentally friendly

Water sold in supermarkets and convenience stores is usually stored in plastic bottles. As you know, plastic bottles cause a lot of waste and pollution to the planet due to the mass production of water. Using a water purifier, you can save the environment and be assured of an even healthier supply of fresh and clean water, as the device uses an intelligent water tracking system that enables you to save water.

  1. Saves time

Using a water purifier can help you save a lot of time and energy, as mundane tasks such as boiling water can be sped up. Usually, boiling water is done by using a designated water filtration jug that often takes too long to boil water. With a hot and cold water purifier that has an insulating layer and heating elements, you can be assured of having boiling water within minutes.

Types of water purifiers

At least six types of water purifiers or purification methods are allocated to different water issues and perform a specific action that can be noticed in water purifiers in Malaysia. A water purifier contains these water purification methods targeted to remove substances that should not be in the water. Typical water purifiers or purification methods include distillation, reverse osmosis, ultraviolet, activated carbon, ultrafiltration and sediment filters.


The most dangerous chemicals and microbes in contaminated water can be eliminated using distillation. It is one of the only techniques to remove bacteria, herbicides, pesticides, nitrates/nitrites, lead, arsenic, coliform, and other contaminants. The polluted water is heated to a boil; the vapour that rises during this process is collected, cools, and then condenses back into clean drinking water. Because the impurities don’t dissipate as quickly as steam, they remain in the container where they were boiled.

Reverse osmosis

Reverse osmosis is a technique for water purification that eliminates particles, chemicals, salts, minerals, and other contaminants from drinking water. Pressure is used in reverse osmosis to turn around how liquids usually pass through semi-permeable membranes. Systems for reverse osmosis do not need electricity to push water through the membrane. They substitute water pressure instead. A mechanical (sediment) filter and an absorption (activated carbon) filter are two standard supplementary filters with reverse osmosis.


A technique for purifying water called ultraviolet disinfection can get rid of the germs and chemicals that are the most dangerous. To accomplish this, ultraviolet radiation destroys the water’s germs like Legionella, E. coli, and Staphylococcus. Producing ultraviolet light only eliminates living things. Therefore, this technology is typically combined with reverse osmosis and activated carbon.

Activated carbon

The most popular application of the water purification technique known as activated carbon filtration functions is eliminating the chlorine taste from tap water. Pesticides, herbicides, volatile organic compounds (VOCs), heavy metals like lead and arsenic, and much more can all be eliminated with this method. Granular activated carbon and activated carbon blocks are the two forms of activated carbon.

Activated carbon is ground into a fine powder and assembled into a carbon block water filter. Then, a binder is added to this powder and crushed into a solid block. To purge pollutants from drinking water, granular activated carbon filters use carbon loosely bound in powder form.


Reverse osmosis and ultrafiltration are both techniques for filtering and purifying water, and both involve membranes. The primary distinction between the two is that reverse osmosis only filters out particles larger than 5 nanometers in size, while ultrafiltration also excludes particles larger than 1 nanometer.

More pollutants and turbidity can be eliminated by ultrafiltration than by reverse osmosis. Water is purified by ultrafiltration when forced through a thin membrane under high pressure. Water molecules are caused through the membrane’s microscopic pores by the pressure, while larger particles are too massive to fit through and stay on one side of the membrane.

Sediment filters Sand, silt, and rust are examples of the enormous dirt and dust particles that sediment filters are made to remove. A pre-filter for well water is the most typical application for this water filter. A sediment pre-filter can prolong its life and prevent damage to the following filtration stage. Sediment filters are usually the first water purifier filters, as noticed in the Snaptec Aurra water purifier.

What is a water filter?

A water filter enhances water quality by removing undesirable contaminants such as hardness, sediment, taste and odour, and bacteria. A water filter reduces water contamination by using a thin physical barrier, a chemical reaction, or a biological reaction to remove contaminants. When the impurities are removed from the water, it is safe for the body to consume.

A home water filter is typically placed where the main water shut-off valve is located. Some water filters are also placed under the sink, connected to a pipe leading to the main water supply.

Water filter benefits

There are several benefits to using a water filter, and these are the main ones:

  1. Effectively removes impurities in the water

Water filters can eliminate harmful toxins and impurities from the water, including heavy metals like arsenic, lead, and mercury. Water filters also remove disinfection byproducts, limescale and chlorine. At the same time, water filters deftly ensure that crucial minerals like magnesium, fluoride, calcium, and zinc are kept in the water.

  1. Cost-effective

Filtering tap water with a water filter is significantly less expensive than purchasing plastic bottled water. Since tap water is used to fill these plastic bottles, you are only paying for the bottle packaging, which is a waste of money. You can save money by investing in a professional water filter, and the water you drink will be of superior quality because it has been properly filtered.

  1. Low maintenance

Using a water filter is easy and convenient as no complicated instructions exist. The water filter only needs a quick filtration change occasionally; plus, it is portable and durable.

Types of water filter

There are at least five types of water filters that each address a specific and different water issue found in water filters around Malaysia. These water filters include reverse osmosis, sequestration, absorption, ion exchange, and mechanical filters.

Reverse osmosis

Reverse osmosis removes dissolved inorganic particles like calcium and magnesium ions from water by applying pressure to a semipermeable membrane and forcing water through it. Most of the pollutants are left behind, so the water goes through.

Reverse osmosis systems do not require electricity to force water through the membrane. Instead, they use water pressure. Reverse osmosis is typically used in conjunction with several additional filters, including a mechanical (sediment) filter and an absorption (activated carbon) filter.


Sequestration is the method by which a substance is chemically isolated using scale-inhibiting filters. The filter will prevent issues such as limescale and corrosion, which can poison the water with harmful metals. The filter uses a polyphosphate material to prevent scaling while keeping the essential minerals in the water without softening it.


Absorption uses carbon, most frequently used in water filters, to absorb impurities because it effectively removes them from the water. Carbon quickly absorbs pollutants because it has a large interior surface that is crammed with holes and crannies that can trap chemical contaminants like chlorine.

Granular activated carbon (GAC) in most conventional residential filters absorbs unpleasant tastes and odours to lessen them. The carbon block elements used in more expensive filters are often more effective and have a micron rating for particle removal.

Ion exchange

By switching the magnesium and calcium ions in hard water with other ions like sodium or hydrogen ions, ion exchange is used to soften hard water. As opposed to scale inhibition, ion exchange physically removes the hard minerals, lowering limescale and preparing the water for use in applications where a constant high temperature is maintained, like in coffee makers.

The most typical method for ion exchange is an ion exchange resin, which often takes the form of tiny beads. Some water softeners utilise a resin of a similar type.


The fundamental concept of mechanical filtration is to use a barrier to physically remove any silt, debris, or other particles from the water. Mechanical filters range from a simple mesh that removes big particles to a ceramic filter with an intricate pore structure for pathogenic organisms’ ultra-fine filtration. A mechanical filter will typically be assigned a micron rating, which describes how well the filter can remove particles of different sizes.

Category of water filter

  1. House water filter

A house water filter is a type of water filtration system that will treat the water effectively at the location of an individual’s main water supply. Before the water supply enters the house, the filter will ensure that the water is free of impurities and clean. A house water filter will enable clean water to flow into every household item that needs water, such as a washing machine, kitchen sink faucet, bathroom shower, and more.

  1. Indoor water filter
Indoor Water Filter
Snaptec Aurra

An indoor water filter is a more specific filter usually placed on the countertop or under the countertop of your kitchen table. This type of water filter will filtrate the water coming through your regular kitchen faucet to produce clean water that is safe to drink. An indoor water filter comes with multiple filters that will help remove impurities and chemicals from the water.


Overall, water filters and water purifiers exist to create filtered water that is safe for all of us, as water is essential to the human body and has many health benefits. We must consume water daily, as it will keep us from falling sick easily and help regulate our body functions effectively. Between a water filter and a water purifier, it is best to go for a water purifier if you want clean, drinkable water to be supplied. An example would be the Snaptec Aurra water purifier, as it can deliver clean water that is safe to consume.

However, a water filter does have its benefits, especially when it comes to a whole house water filter, as it can supply clean water throughout your entire house. Depending on your needs, you should be able to decide based on the qualities and comparisons above.

Water purifiers and water filters share a common purpose in eliminating impurities. Nonetheless, water purifiers take another step by eradicating biological contaminants and extracting minerals from the water.

Purified water undergoes a process akin to filtered water, with additional steps such as reverse osmosis, distillation, or deionisation. The outcome is significantly purer than filtered, spring, or tap water.

Apart from ensuring fundamental safety, a considerable number of individuals opt to filter their tap water to eliminate minerals and particles that might impact its taste. We will guide you through various types of tap water filters, assisting you in selecting the most suitable one for your requirements.
