Water is the most important liquid for humans. Scientists say you can live more days without any food than water. Though, there is plenty of water on the earth, as water is also the most common carrier for countless harmful viruses and bacterias, finding safe, drinkable water has been a challenge. And that’s the reason why you need a safe and reliable water filter which can produce clean and safe drinking water, just like how you will need air purifier.
Here in Singapore, we might have access to one of the cleanest tap water in the world but, there is no wrong in being 100% sure with our drinking water. For that purpose, you need a water filter which can clarify and kill germs the tap water might have before you drink it.
In this article, we discuss different filtration technologies available here and the top 5 best water filters that are available in Singapore.
Different Types of Filtration
Before we begin our list, let’s go through the various types of filters available. Each of these filtration techniques serves a different purpose. If you know about them, you can choose which one suits your needs best. Some commonly available filters in Singapore are
- Ceramic Filter
- Activated Carbon Filter
- Deionization Filter
- Ultraviolet Filter
- Reverse Osmosis Filter
- Alkaline Filter
A ceramic filter is one of the most common filters used around the world. This simple filtration mechanism removes visible sediments, debris and dirt. Due to the absence of any chemical process, it cannot remove any chemical impurities.
Newer technology uses Activated Carbon traps for the purification process of water. This type of filter is known as Activated Carbon Filter. It has the ability to neutralise common impurities like lead and mercury, however, it’s not so effective again ionised compounds like nitrates and phosphates.
You’ll be needing a De-ionization filter if you’re after that kind of filtration. This type of filter can remove total dissolved solids otherwise known as TDS.
The filters mentioned above are good at their level, nevertheless, it can not kill any living organism (microorganism) that might be in the water. Only a modern Ultraviolet or UV Filter is effective in killing microorganisms in water. In fact, it can kill almost 99.9% of contaminants found in water.
The downside of the UV filtration is its inability of residual treatment, it can not remove any solid particles present in the water. Nowadays, a popular filtration process is RO or Reverse Osmosis Filter. It can remove almost all the heavy toxins including arsenic, fluoride and nitrates.
However, it cannot treat simpler contaminants like chlorine and volatile organic compounds. The pH level for drinking water lies between 6 to 8.5. If the level is out of this range, the Alkaline filter is used to bring the pH level in the drinkable range.
Because of the shortcomings in every single process, often a total water filter uses 2 or more filtration techniques in combination to produce the best result. With these in mind, let’s jump into the list of top 5 best water filters in Singapore.
The Best Water Filter in Town: Xeltro CT22 – Countertop Twin Water Filter
Would you choose something less than the best for your safety? If not, then the best water filter in Singapore must be this countertop twin filter named Xeltro CT22!
The 7-layer ultra twin filtration system of Xeltro CT22 delivers every drop as the purest. That’s right, every drop of water passing through this filter has to go through 7 stages of the filtration process. 
Let’s take a closer look at all the 7 layers Xeltro CT22 has to offer.
It begins with 0.1 Micron Ceramic filter which is engineered to filter out sediments, heavy metal, rust, Giardia, cysts and bacteria as small as 0.1 Micron in size. Hazardous bacteria like E-Coli and Cryptosporidium are trapped here.
Up next we have the Far Infrared Ray or the FIR Layer which not only softens the hard water but also removes the bacterial growth and unpleasant odours to deliver tasty & safe drinking water.
Later in the line, we have the Ion-exchange Resin & the Anti Bacterial Ions. The ion exchange layer helps to exchange harmful Calcium and Magnesium ions with Sodium ions. Anti Bacterial layer kills and removes almost 90% of the harmful bacterias by breaking down the bacterial cell membranes.
For the fifth and sixth layer, the Alkaline Medium & the Activated Carbon Layer do their jobs perfectly by controlling the pH and removing impurities. The activated carbon layer used in the Xeltro CT22 is a Kinetic Degradation Fluxion or KDF granular activated carbon layer which is not only capable of removing 99.99% residual chlorine but also deodorizing, improving the colour and taste of the water.
After going through all these filtration processes, the water now needs to pass the most extreme treatment mechanism known as Filtech Hybrid Carbon Membrane Technology. This ultimate stage utilizes Filtech’s hybrid carbon fibre microporous membranes to further treat and deliver the most purified quality drinking water.
