Best water purifiers

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 top 10 water purifiers to check out.

1. Filtech Countertop Twin Water Filter – 7-layer filtration system from Japan

Japan has long since gained the reputation of manufacturing trustworthy products and in the product category of water filters, you’ve got the Filtech Xeltro CT 22, a countertop twin water filter.

Despite its compact size, this powerful contraption hides a seven-layer filtration system with a 0.1-micron ceramic filter, FIR layer, ion exchange resin, anti-bacterial ions, KDF activated carbon and their specially-made carbon membrane filter. 

For our Science-averse friends, this translates to a system that removes everything you don’t want in your water, from bacteria to rust while deodorising it along the way.

Fitting it into your tap is a breeze as well, as each purchase comes with multiple adaptors for an easy installation. A video tutorial is also available to guide you through any hiccups.

We’re often so busy with our lives, remembering when to change the purifier filter is probably the least of our worries. For all the busy bees out there without brainpower to spare on the nitty-gritty, consider the Philips On-Tap Water Purifier WP3811/00. 

While there are many similar models by the brand out there, only this specific one comes with a handy colour-coded alert function to easily tell when the filter needs to be changed. Simply check the colour of the filter membrane once every few weeks, to see if it matches the colour guide on the lid. 

Once it turns into the specified shade of brown or dark grey, switch out your filter cartridge for a new one.

At $1,099, Panasonic’s 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 five different pH levels – with three alkaline modes, one acidic and one regular.

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.
