Does a Tap Water Filter Work? | Singapore Residents Guide

When it comes to safe drinking water in Singapore, lots of people question whether or not they actually need a home water filter. Singapore’s tap water comes and goes as one of the purest throughout Asia, after all.

But is it pure enough to be consumed straight from the faucet, or is it worth spending your cash on one anyway? In this article, we will tackle the usual questions Singaporeans have regarding tap water, describe the function of filters, and let you determine for yourself if a tap water filter is a worthwhile selection for your home.

Indeed, the Singapore tap water meets the World Health Organization (WHO) quality standards for potable water. PUB (Public Utilities Board) , the national water utility, treats and analyzes the water systematically to make it pure and clean.

However, though the effluents released through the plants are clean, along the way they may pick up impurities. Outdated water mains, plumbing system within dwelling units, and storage facilities within buildings sometimes introduce impurities. That is the reason why the majority of households in Singapore like installing a tap water filter as an extra measure of protection.

Although the tap water for Singapore is safe on the international scale, it can consist of minute amounts of the following:

• Chlorine – employed for disinfection purposes but can alter taste and odour.
• Rust or sediment -- from aged tank storage structures and pipes.
• Microplastics – trace amounts can still be present in tap water.
• Heavy metals – possibility in older dwellings whose plumbing is faulty.

In the situation of sensitive populations such as infants, expectant women, or immunocompromised persons, such contaminants can be problematic. That is where a filtration system for tap water comes into play.

A kitchen tap water filter is a system that removes or reduces unwanted items from your kitchen tap water. Different filters use different technologies, for instance:

• Activated Carbon Filters – eliminate chlorine, odors, and organic compounds that affect flavor.
• RO Systems (Reverse Osmosis) - Eliminate dissolved solids, heavy metals, and up to 99% of impurities.
• UV Filters – kill bacteria and viruses with ultraviolet light.
• Sediment Filters – trap dust, sand, and rust particles.

With the integration of these technologies, a quality water filter can make your kitchen tap water pure, safe, and more palatable.

The short answer is: Yes, it is effective to use a tap water filter. Although the tap water of Singapore is safe by default, filters add another level of protection and make the overall drinking experience better.

That is why Singaporeans typically install a home water filtration system:

• Improved Taste and Smell – filters remove chlorine, making the water healthier and tastier.
• Extra Coverage – against heavy metals, sediments, and microplastics.
• Health Benefits – safer potable water for children, the elderly, and expectant women.
• Convenience – filtered water through your tap eliminates the need to boil your water or buy bottled water.

Boiling can destroy viruses and bacteria, but will not remove chlorine, heavy metals, or microplastics. If you are dealing with a decent-quality tap water filter, boiling will normally not be necessary for daily drinking.

However, if you are unsure about your building’s plumbing system or water tank hygiene, boiling filtered water can add another safety layer, especially when preparing baby formula.

Selecting the proper water filtration system relies upon your needs, budget, and lifestyle. Let’s consider some of the most common types:

• Can be fitted straight on your faucet.
• Affordable and convenient.
• Small households only.

• Provide stronger filtration.
• Some models incorporate reverse osmosis for total purity.
• Ideal for families who require safeguarded drinking water daily.

• Installed under the kitchen sink.
• Provide continuous, high-quality filtered water.
• Saves countertop space.

• Treat the entire house's water.
• Ideal for homes with old piping or water tanks.
• More expensive but offers full coverage.

When you discuss tap water filters for Singapore, there is one company you can rely on, and it is Waterdrop. Here’s why:

• Advanced Water Filtration Technology – Waterdrop filters use multi-stage filtering, like activated carbon and reverse osmosis, and can remove up to 99% of impurities. Makes You Taste Better – not you, though; the water.
• Space-Efficient Design – especially the Waterdrop under-sink and countertop slim designs, best suited for Singapore’s compact kitchens.

Yes. Even though tap water is safe, a filter provides extra protection and good-tasting water, especially for families with children or older people.

Indeed, the vast majority of filters—particularly activated-carbon filters—will eliminate the chlorine, leaving your water tasting cleaner.

Varies with use and filter type. Typically, faucet filters last for 2–3 months and reverse osmosis filters for 6–12 months.

Some filters can, but not all. To be properly protected, choose a system with RO membranes or UV sterilization.

Not quite. With a proper filtration system, your filtered tap water can be just as clean—and possibly cleaner—than bottled water. Plus, it’s more cost-effective and sustainable.

Even though the tap water in Singapore is pure and safe for consumption, a tap filtration system offers added defense and enhanced quality and taste. For households with babies, older relatives, or individuals who are sensitive to chlorine and other impurities, the addition of a filtration system is a worthwhile investment.
