Tap water in Singapore may be safe for drinking, but if you’re from a typical Singaporean family, chances are you’re used to only drinking tap water that has been boiled. While that is a good enough way of getting rid of most germs, there are often still trace amounts of chemicals like chlorine, lead and mercury that don’t go away even after bubbling it at 100°C. For clean-as-can-be water straight out of your tap, upgrade your kitchen with a water purifier.
On top of saving time and electricity, they’re able to sift out 99% of germs and unwanted chemicals in the water. For all those considering getting one, below are the best water purifiers and filters in Singapore to check out.

Water filters are also part of a water purifier’s system and its filtration processes. Here are some of the common types of filters you can find:

At $2,546, the Panasonic Water Alkaline Ionizer might seem like a pricey contraption – but if you’re looking for something that provides added health benefits, this is one to consider. On top of removing impurities in your water, this dispenses water in 7 different pH levels – alkaline, purified, and acidic water.
There’re plenty of studies behind it but in essence, alkaline water is said to help with boosting health, by balancing out the acidic food and drinks we consume, like sodas. Some benefits reported include improving bowel movements and overall immunity.
Drink it as it is or use it in your cooking – it’s said that it can slightly enhance the flavours and textures of certain food as well!
P.S. For those with troubled skin, this purifier also has a mode that dispenses slightly acidic pH5.5 water which – as beauty gurus might know – matches the natural acidity levels of our skin. Use this to wash your face daily for softer skin and fewer breakouts.
