Outdoor Water Filters in Malaysia – Your Complete Guide

Let’s be honest, despite being a truly wonderful place to live, Malaysia is a country that is not blessed with outstanding water quality.

If you want to drink/use water, it often has to be filtered first. And the best way is through an outdoor water filter.

But with so many outdoor water filter brands on the market, it is not an easy decision for you to pick one.

That’s why we made this guide to help you understand everything about outdoor water filtration systems. Let’s dive in.

What is an Outdoor Water Filter?

An outdoor water filter is a water filtration system which is being installed as a “point-of-entry” filter to provide clean water for the entire house.


Outdoor water filters work by providing cleaner water right from the point-of-entry for whole house water usage. It filters water in your kitchen, bathroom, and laundry room.

Is the Water Filtered from an Outdoor Water Filter Safe to Drink?

While a top-quality outdoor water filter like 3M AP902 removes sediments, particulate, sand and rust down to 5 microns (10 times finer than a strand of hair!), an indoor water filter is still recommended for drinking purposes.

Which is the Best Outdoor Water Filter in Malaysia?

There are 3 key factors you MUST consider when buying an outdoor water filter in Malaysia:

  • NSF tested/certified
  • The technology used to filter the water
  • Maintenance

We will explain each of them later in this guide. For now, the outdoor water filters that fulfil the 3 criteria above are:

3 Key Factors You Cannot Miss When Buying an Outdoor Water Filter in Malaysia

1) NSF Certification/Testing

You don’t need to be a scientist to find the best outdoor filters that protect your family from harmful impurities in the water. This is because NSF has done the hard work for you.


NSF is an independent organisation that has, since 1944, spent its time evaluating the quality of filtration systems worldwide. They are a respected body and are seen as the main name within the water industry.

If you don’t find the NSF certificate or testing in any water filters, simply walk away and find another one which fulfils this most important factor.

2) Technology

Linked with the above, modern filter systems need to come with the right kind of fitting technology.

For example, 3M AP902’s non-woven pleat filtration media removes sediments, particulate, sand and rust down to 5 microns.

What do 5 microns mean? It means 10 times finer than a strand of hair!

Another technology it incorporates is its high flow rate (up to 75.7 litres per minute). In other words, it does not interrupt the water flow rate in your house.

3) Maintenance

Many brands today require you to sign up for their long-term maintenance plans.

The truth is, a modern outdoor water filter should allow you to change the cartridge yourself with ease.

This can save you a lot of money and time in the long term. Even better, 3M outdoor water filters allow easy cartridge change-out with no backwash needed.

Aside from the 3 factors above, you should ask yourself “Is the brand credible enough to provide me support when needed?

We recommend that you take the time to look into the most reputable brands within the industry. Fortune 500 companies like 3M is regarded as pioneer in the water filtration system.

Clean Water for Your Home – The Power of Whole House Water Filtration

Whole house water filtration systems or commonly known as outdoor water filters are like your home’s health guardians, ensuring that the water you use every day is clean and safe for you and your family.

They work to remove all sorts of impurities from the water that comes into your house. This is important because water quality affects everything you do at home – from drinking and cooking to bathing and doing laundry.

Let’s dive in and discover why investing in an outdoor water filter can make a positive difference in your household’s health and well-being!

Ensuring Health and Safety: Why Outdoor Water Filtration is Essential

Ensuring Clean Water: Addressing Water Quality Concerns

In residential areas, water quality concerns can often arise due to various impurities present in the water supply.

Common issues include chlorine, sediment, heavy metals, and contaminants that find their way into our taps.

While chlorine is used to disinfect water, its presence can result in an unpleasant taste and odour. Sediments and heavy metals, like lead and mercury, can also make their way into the water, posing health risks over time.

These impurities not only affect the taste and smell of water but can also be detrimental to household appliances and plumbing.

When left unfiltered, these elements can lead to mineral deposits and scale buildup, shortening the lifespan of appliances like dishwashers and washing machines.

Enhancing Health: The Benefits of Filtered Water Throughout the Home

The health benefits of having an outdoor water filtration system extend beyond mere convenience.

Filtered water ensures that harmful substances are removed, providing your family with a healthier water source for all their needs.

By reducing exposure to contaminants, such as lead, chlorine by-products, and other pollutants, you can protect your family from potential health hazards.

Filtered water is especially crucial for vulnerable individuals, such as young children and the elderly, who are more sensitive to the effects of impurities in water.

Furthermore, having filtered water readily available for drinking, cooking, and bathing allows your family to enjoy the full potential of a healthier lifestyle.

With a water filter system, not only can appliances last longer and plumbing stay in better condition, but your food can taste better, and most importantly, you can have the peace of mind that comes with knowing your family is consuming clean and safe water every day.

Behind the Scenes: Unraveling the Workings of Outdoor Water Purifiers

The Heart of Whole House Filtration: Point of Entry Filtration

At the core of an outdoor water purifier lies the ingenious point-of-entry filtration setup.

Installed at the main water supply entry point of your home, this strategic location ensures that all water flowing into your house undergoes thorough purification before it reaches any faucet or appliance.

By intercepting the water at the very source, the system acts as a robust defence, protecting your entire household from potential waterborne contaminants.

Whether it’s the water in your kitchen, bathroom, or laundry room, you can rest assured that it has already been treated and purified, providing you with the highest quality water for all your daily needs.

Harnessing Cutting-Edge Filtration Technologies

Outdoor water filtration systems harness an array of advanced filtration technologies to combat various impurities effectively.

Each technology plays a specific role in targeting and removing specific contaminants, ensuring comprehensive water purification.

Sediment filters act as the first line of defence, capturing larger particles like sand, dirt, and rust that may be present in the water.

Activated carbon filters, renowned for their adsorption capabilities, effectively remove chlorine, volatile organic compounds (VOCs), and unpleasant tastes and odours, leaving water tasting fresh and natural.

For an even more thorough purification process, reverse osmosis comes into play. This sophisticated technology utilises a semipermeable membrane to remove microscopic particles, dissolved solids, and heavy metals, delivering crystal-clear water.

By combining these filtration technologies, whole house systems provide a multi-layered defence against a wide range of contaminants, ensuring that every drop of water flowing through your home is pure, clean, and safe for consumption and daily use.

Unveiling the Elixir of Pure Water: Key Benefits of a Whole House Water Filtration System

Comprehensive Water Treatment

One of the most enchanting attributes of a whole-house water filtration system is its ability to bestow the gift of pure water upon every nook and cranny of your home.

With this filtration marvel standing guard at the point of entry, all water sources, from the kitchen to bathrooms and laundry, are embraced in its benevolent embrace.

Gone are the days of fretting over different water filters for various taps, for this system unifies them all, ensuring that each droplet of water that graces your household is free from contaminants and impurities.

In the kitchen, the purity of filtered water elevates the taste and quality of meals, accentuating the flavours of your culinary creations. As you bathe in the embrace of pristine water, the worries of harsh chemicals and irritants washing over your skin fade away, leaving behind a refreshing and rejuvenating experience.

The sanctuary of clean water extends to your laundry, where the absence of impurities safeguards your clothes from harsh minerals and ensures they emerge brighter and softer, prolonging their life.

In the realm of practicality, filtered water plays a vital role in preserving the health of your home’s plumbing fixtures and pipes.

Removing harsh minerals curtails the chances of corrosion and wear on these essential components. The absence of mineral buildup also reduces the risk of clogs and blockages in pipes, maintaining a more efficient and seamless water flow throughout your home.

With filtered water as a diligent guardian, you can rest assured that your plumbing system remains in better condition over time, alleviating the need for costly repairs and ensuring a smoothly running water supply for your daily needs.

Appliance and Plumbing Protection

Filtered water brings more than just a touch of practicality to your home, offering tangible benefits that extend the lifespan of household appliances.

Reducing the presence of minerals in the water, particularly in areas with hard water, minimises scale and buildup that can accumulate over time.

This protection shields appliances like dishwashers and washing machines from potential damage caused by mineral deposits, allowing them to perform optimally for longer periods.

Beyond these appliances, other water-dependent devices, such as coffee makers and kettles, also benefit from the gentler touch of filtered water, resulting in prolonged functionality and smoother performance.

Enhanced Water Taste and Odour

Embracing a whole-house water filtration system ushers in a delightful transformation in the taste and aroma of your water, turning every sip into a palatable pleasure.

As water flows through the purifying embrace of the filtration system, it bids farewell to the lingering presence of chlorine, volatile organic compounds (VOCs), and other impurities that may tarnish its flavour and aroma.

The result is a remarkable improvement in the overall taste, making your water noticeably cleaner and more enjoyable to drink.

Whole house filtration works wonders on your water, improving its taste and smell throughout your home. No more lingering chlorine notes or earthy impurity tinges; filtered water ensures a clean and refreshing flavour.

Enjoy odour-free water from every faucet, shower, and washing machine, elevating your daily tasks and bringing refreshment to your home, making drinking, cooking, and bathing a delightful experience.


Is an outdoor water filter difficult to install? I have no prior experience, and I want it to be fuss-free.
Installing an outdoor water filter can vary depending on the specific model and your home’s plumbing setup. While some systems may require professional installation, many manufacturers design their filters with user-friendliness in mind, making the process straightforward and fuss-free.

DIY installation kits often come with comprehensive instructions, and some systems feature quick-connect fittings that simplify the setup.

If you prefer a hassle-free experience, consider consulting with a professional plumber or opting for models explicitly marketed for easy installation.

Additionally, some whole-house water filtration systems, like the 3M ones, are designed to be exceptionally easy to install and maintain. With features such as quick-change cartridges, the process becomes even simpler than it may seem at first glance. So, you can have peace of mind knowing that certain systems offer a fuss-free installation and maintenance experience.

Does it cost a lot?
The cost of an outdoor water filter system in Malaysia can vary based on factors such as the brand, filtration capacity, and additional features. While initial investments may seem higher compared to smaller point-of-use filters, the long-term benefits often outweigh the cost. Whole house systems eliminate the need for individual filters on multiple faucets, saving you money on replacement cartridges over time.

Additionally, the protection they provide to your plumbing and appliances can lead to savings on repairs and replacements. Remember that the price of a system should be viewed considering the comprehensive water quality improvements it offers for your entire home.

Is the whole house water filter system suitable for all kinds of dwellings?
The suitability of a whole-house water filter system can vary based on the type of dwelling you reside in. These systems are most commonly installed in single-family homes, townhouses, and certain commercial properties with direct access to the main water supply entry point. For such dwellings, a whole-house water filter system can effectively treat all water entering the property, providing clean and safe water throughout.

Are there any alternatives for outdoor filtration in apartments?
For apartments or rented properties, the installation of an outdoor water filter system may not be feasible since it typically requires access to the main water supply entry point, which is usually located outside the individual living units.

However, there are alternative options available, such as the 3M Home POE 3WH-STD-S01H Pre-Filter. You can also consider under-sink filters or faucet-mounted filters, which can be easily installed on specific faucets or showerheads.

These filters provide clean water for drinking and bathing without the need for major modifications to the plumbing system. Alternatively, you can also use countertop water filters like 3M Countertop Drinking Water System CTM-02 which is a perfect solution for smaller households.

Will an outdoor water filter system affect my water pressure?
A well-designed outdoor water filter system should not significantly impact your water pressure when properly installed and maintained.

High-quality systems are engineered to maintain the appropriate flow rate, ensuring you have sufficient water pressure throughout your home.

Regular maintenance, such as timely filter replacements and system cleaning, plays a crucial role in preserving optimal water pressure.

When opting for an outdoor water filter system, selecting a reliable and reputable outdoor water filter becomes essential. Since the filter system is installed at the point of entry, you’ll want a seamless and hassle-free transition.

Reputable brands prioritize efficiency and performance, ensuring minimal interference with your water pressure and flow. Investing in a trustworthy system guarantees peace of mind, allowing you to enjoy the benefits of purified water without any inconvenience.

Are outdoor water purification systems eco-friendly?
Outdoor water purification systems are eco-friendly solutions that eliminate the need for multiple point-of-use filters scattered throughout the house.

With these systems in place, there is no longer a requirement for individual filter cartridges in each faucet or shower faucet, significantly reducing the generation of plastic waste from these cartridges.

By treating all water at the point of entry, whole house systems streamline filtration efficiency and minimise unnecessary waste.

Their consolidated approach to water filtration makes them a responsible and environmentally-conscious choice for households seeking cleaner water without compromising the planet’s well-being.

Embrace Pure Water for a Better Home

In conclusion, outdoor water filtration systems offer a multitude of benefits that elevate the quality of life for you and your family.

These remarkable systems provide clean and safe water at every tap, shower, and appliance, ensuring protection against harmful contaminants and impurities. Investing in a quality outdoor water filtration system is a wise decision that promises long-lasting advantages.

With proper installation and maintenance, these systems offer a seamless and hassle-free solution for achieving optimal water quality.
