Is It Really Safe to Wash Fruits with Malaysia’s Tap Water?

This is a question many people ask — “If tap water isn’t safe to drink, is it really safe to wash our fruits with it?” For households with children, elderly family members, or expecting mothers, this question becomes even more important. After all, we use tap water daily — to wash fruits, prepare baby formula, cook meals — but if the water isn’t clean to begin with, washing more won’t make it safer.
 
Let’s break down this seemingly simple question — because it holds the key to your family’s health.
 
Why is Tap Water Not Safe to Drink, but Still Used for Washing Fruits?
In Malaysia, we all know that tap water isn’t suitable for direct consumption without filtration. Yet, many of us use it daily to wash fruits, clean baby bottles, and even cook soup. At first glance, this might seem contradictory — but there’s more beneath the surface.
How Clean is Tap Water in Malaysia?
Many areas in Malaysia still rely on decades-old piping systems. Combined with heavy rainfall, frequent maintenance, and inconsistent water pressure, even water that looks “clear” can contain invisible impurities.
 
Common tap water contaminants include:
  • Rust and sediments from aging pipes
  • Chlorine residue — used for disinfection, but potentially excessive
  • Microbes and bacteria — especially after storms or pipe repairs
  • Heavy metals — long-term exposure can be harmful to health
 
Signs Your Home Water May Not Be Clean:
  • Water smells odd or like bleach
  • Skin feels itchy or dry after a shower
  • Yellow stains or scale buildup in kettles or around taps
  • Fruits feel slippery or have a filmy residue after washing
 
If you notice any of these, it’s likely your water quality needs attention — especially before using it to clean food or feed your family.
 
Washing Fruits with Dirty Water = Wasted Effort
Fruits and vegetables often carry soil, pesticides, or bacteria on their surface. Washing them is essential — but if the water you use isn’t clean, it’s like using a dirty cloth to wipe a clean surface. You’re not removing the contaminants — you’re just adding new ones.
 
This is especially concerning for children, who tend to consume more fruits and are more sensitive to contaminants. Over time, even minor exposure can have an impact on health.
 
So, the real question isn’t “Should I wash my fruit?” — it’s “Is the water I use to wash the fruit truly clean?”
Kitchen vs Outdoor Filters: What’s the Difference?
Many families install a kitchen water filter and believe that’s enough. But a kitchen unit only filters drinking and cooking water — what about the water used for bathing, laundry, or washing fruit?
 
Kitchen Water Filter:
  • Ideal for consumption e.g. drinking, cooking, and making beverages
  • Removes chlorine and some impurities
  • Only protects water at one point (kitchen tap)
 
Outdoor Water Filter:
  • Installed at the main water inlet, before water reaches your taps
  • Filters all water used throughout the home
  • Provides safer water for showers, laundry, and food prep
  • The first line of defense against “invisible pollution”
 
If you want to ensure every drop your family uses — from showering to food washing — is clean and safe, a combination of both kitchen and outdoor filters is a necessity.

So, Can You Wash Fruits with Tap Water? Let’s Be Realistic
While Malaysian tap water meets basic safety standards at the treatment plant, it travels through kilometers of old pipes before reaching your home. Along the way, it can pick up many contaminants. That’s why experts strongly advise against drinking unfiltered tap water — and the same logic applies when washing fruits and food.
 
The bottom line is: if your water isn’t clean, you’re just washing with dirty water.
 
Final Thoughts: Clean Water is the Foundation of Family Health
Every day, we prepare fruit for our children, brew tea for our parents, and cook meals for our family — but no matter how careful we are, if the water we use is contaminated, we’re missing the most basic layer of protection.
 
True peace of mind comes not just from washing thoroughly — but from using clean, filtered water at the source of your home.
 
If you’ve never considered a whole-house water filtration system, now might be the time. A reliable outdoor water filter, like the NESH Membrane Queen, could quietly become one of the most impactful decisions you make for your family’s long-term health.
 
Because health — real, lasting health — starts with every drop we use, every day.

The high precision ultra-filtration membrane is made of hollow fibre with the size of 0.01 micron. This advanced technology is able to block any residues or micro-organisms that are bigger than 0.01 micron in size.

Impurities in the tap water are effectively blocked at the main water supply pipe before water entering the house. It removes bacteria, metal rust, heavy metal, mud and other residues derived from the recontamination of tap water during its journey through the water supply pipes before reaching our house water taps.

Membrane

The function of membrane simulates our human body cells. Each individual membrane is high in density, therefore it is able to absorb, purify, separate and filter. Various industries like brewery, distillery, and textile have applied this technology in their production. Today, this matured membrane technology has been introduced into our household and further developed into highly effective outdoor filtration system.

O.O1 Micron

The size of each membrane hollow fibre is 0.01 micron, which is 10,000 times thinner than a human hair. It can filter out anything that is bigger than 0.01 micron such as hepatitis A virus or calicivirus that is 0.025 micron in size. It can handle dirty water which is 100 times dirtier than average tap water.

It was proven through a series of SIRIM tests that the revolutionary NESH membrane is able to filter out 99.99% of residues like mud, sand, metal rust, heavy metal, hair and etc. The performance of this amazing technology is not achievable by conventional water filtration systems.

What is Activated Oxygen (O3)?

‘Ozone is the most natural and powerful disinfectant known to man.’

What is Activated oxygen?

Activated oxygen is most commonly known as Ozone or O3. Ozone is the planet’s strongest oxidiser and disinfectant readily available for household and commercial use. It is 3,000 times faster-acting and more effective than chlorine in killing bacteria and viruses and leaves behind no residues, off flavours or tastes.

Activated oxygen or ozone is created when lighting strikes oxygen molecules (O2) in the atmosphere, splitting them into single oxygen atom (O) that then combines with unbroken O2 to create O3 or ozone that has a brief lifespan. The extra atom of oxygen becomes a scavenger, destroying pollutants, bacteria, viruses and odours. Colourless and non-toxic, this tri-atomic molecule is a powerful oxidation and decomposition agent that enables sterilisation and deodorisation when combined with other chemical properties.

Application of Activated Oxygen (Ozone) Today

Ozone has been used in many water treatment applications for over 100 years.

Today, ozone technology is widely used as an extremely strong oxidising and disinfecting agent, as well as a catalyst, in various industries, such as water treatment, health care, chemicals and food and beverage.

Penetrating into different areas, the application of ozone in our daily lives is a significant technological development. Set up in Canada in 1973, the International Ozone Association (IOA) holds an international conference every two years to confer the latest in ozonation development and technology.

Among the popular ozonation technologies in use today are the free-radical, ultraviolet (UV), plasma and electrical discharge method. NESH Qoozo is using one of the most popular ozone generating technology: electronic discharge method to produce Activated Oxygen (Ozone) for household use.

Main Areas of Ozone Application Today

‘Ozone is proven to be 3000 times faster than chlorine in eliminating bacteria.’

  1. Facial Cleansing Machines- Ozone destroys bacteria, hence it is extremely effective for detoxifying skin and combating skin problems with no painful side effects.
  2. Swimming Pool- Because of its strong oxidation and disinfection mechanism, ozone is used in swimming pools to replace chlorine and bromine containing disinfection chemicals. Olympic pools must use ozone for disinfection and oxidation.
  3. Bottled Water- Ozone is a common technology for sanitising water before the filling process, and it is USDA requirement for every bottled water be dosed with ozone as a part of the filling process.
  4. Dentistry– Ozone widely used in dental treatments as it has shown promise in helping disinfect areas of chronic gum infection.
  5. Wineries and Breweries- Ozone is used to disinfect barrels tanks and other equipments.
