What is best tap water filter in Singapore?

We all take water for granted. As long as it looks clean and tastes good, we are content to drink it. But is this always the case? If you live in Singapore, you know that tap water here can be quite hard on your skin and hair when left untreated. You may also have a sensitive stomach or heartburn from drinking unfiltered water over time. In this blog post, we will discuss some of the best tap water filters in Singapore to help you find one that suits your needs!

Do tap water filters work?

A ConsumerReports comparison of a wide range of commercially available water filters revealed that most filters do a decent job at removing contaminants from tap water, assuming they are designed for this purpose.

Consumer Reports deputy editor Celia Kuperszmid Lehrman said “The good news is there are lots of options for not an arm and leg to ensure the purity” in her report on filter comparisons.

Types Of Tap Water Filters

With so many types of water filters available, it’s important to understand the different ways they work. While there are five basic filter methods that treat a variety of problems with tap and bottled waters alike.


The basic idea of mechanical filtration is to physically remove dirt or any particles in the water using a barrier. Mechanical filters can be anything from a mesh that filter out large debris, such as slugs and clamshells, to ceramic filters which have an extremely complex pore structure for ultra-fine filtration of pathogenic organisms. A filter will usually carry with it a micron rating; this indicates how effective the different types are at removing small particulates like bacteria or protozoans within some range around their nominal size – typically 0-3 (small), 3-10 (medium) and 10+ μm(large).

  • 5 micron – Will remove most particles visible to the naked eye.
  • 1 micron – Will remove particles which are too small to see without a microscope.
  • 0.5 micron – Will remove cysts (giardia and cryptosporidium).


In order to receive clean water from the tap, most people go through a process called absorption. This is where carbon captures unwanted chemicals in your drinking and cooking water. The reason for this is that it has so many nooks and crannies which can trap any impurities such as chlorine or other undesirable elements. If you want cleaner tasting food with fresher smells then install one of these filters on your faucet!


Sequestration is the process of chemically isolating a substance. It may sound like an obscure term, but it’s actually commonly used in food grade polyphosphate to inhibit scale and corrosion on any surfaces they come into contact with. Polyphosphates are only introduced in very small amounts that prevent calcium and magnesium from forming as limescale or rusting things such as pipes over time- meaning no need for soap!

Water softening is the process of removal a mineral or sediment from water. Hard minerals in very hard water can be removed with scale inhibition, but ion exchange may work better for other applications especially if there’s alkalinity levels over 180 ppm and constant temperatures between 95°C to 100°C (very hot).

Ion Exchange

Ion exchange is a process used to soften hard water by exchanging the magnesium and calcium ions found in hard water with other ions such as sodium or hydrogen. Contrary to scale inhibition, ion exchange physically removes the icky minerals that lead to limescale buildup on your coffee maker’s pipes without compromising its high temperature performance!

For those who don’t know, ion exchange is a process where ions are swapped in and out of the resin by passing water through it. Ions can be exchanged for other atoms or groups of atoms with similar properties as they travel through an electrostatic field between two electrodes that have charged poles on them – usually positive and negative charges respectively. Ion Exchange Resins come in multiple forms including beads which use sodium ions to soften hard water so you might want to consider replacing your CTU if necessary!

Reverse Osmosis

Reverse osmosis is an effective way of purifying water. This process works by forcing the liquid through a semipermeable membrane under pressure, leaving only contaminants like magnesium and calcium ions behind in order to create potable, clean drinking water with few impurities remaining.

Reverse osmosis systems are often used in the food industry to purify water for use in coffee. These units can produce up to 99.9% pure water but require a certain amount of waste from its user that has to be sent down the drain, making it more expensive than other filtration methods on average and not as universally employed because of this cost factor even though levels of purity make RO best choice when accuracy is desired below .1%.

Reverse Osmosis Systems have been increasingly utilized by many industries among them being those producing Coffee due their ability provide quality purified drinking water at near perfect percentages exceeding 99%, including less then 1 ppm (part per million) impurities like lead or fluoride without any usage requirements except occasional

What water filter removes viruses?

In the world of water filtration, there are two main types: physical and chemical. Physical filters only work to remove particles larger than one micron in size; whereas, a virus is only nanometers (1-100 nm) wide. Viruses can pass through these filters without any issue whatsoever because they don’t have an electrical charge that will attract it or anything like that! So what about chemicals? Chemical treatments use disinfectants called disinfection byproducts as their active ingredient. These compounds attach themselves onto foreign matter for removal from your drinking supply but unfortunately viruses escape this treatment too due to their small size and lack of electric charges which other contaminants posses such as germs with protein coats do not possess!

There are, however, benefits to filtering your water as viruses can be dangerous and there are simple ways for removing them that ensure you’re drinking safe.
