What Are the Disadvantages of Water Purifiers?

We’re lucky in Singapore to have one of the best drinking water systems in the world. Our tap water meets World Health Organization (WHO) standards and is safe to drink straight from the tap. Yet many Singaporean households choose to install water purifiers for extra peace of mind, better taste or to address concerns about old pipes.

But water purifiers have both advantages and disadvantages. Before you invest in one, you should know the downsides. This blog explores the most common disadvantages of water purifiers to help you make an informed decision.

While Singapore tap water is safe, some people notice the taste or smell of chlorine. This alone makes many households want to filter their water.

Families with babies, elderly members or those with weakened immune systems want an extra layer of protection against possible impurities or pipe residue.

A water purifier gives you peace of mind – knowing the water you drink is cleaner and free of certain contaminants.

Buying a good water purifier can be expensive upfront. RO systems are pricier than simple carbon filters. Beyond the initial cost, maintenance adds up:

• Filter replacements every 3 to 12 months
• Occasional servicing fees
• Possible installation charges
• Long-term costs can exceed the purchase price so budgeting is key.

RO systems can waste 2 to 3 litres of water for every litre filtered which is a big environmental concern – especially in Singapore where we are a water scarce nation.

But newer models have improved efficiency and can reduce water waste to 1:1 or better.

Many water purifiers, especially RO systems, remove not only contaminants but also beneficial minerals like calcium and magnesium.

While most people get minerals from food, drinking demineralised water long term may not be ideal. Some systems now have remineralisation filters to add these minerals back.

Multi-stage filtration can reduce flow rate. For busy households, waiting for filtered water during cooking or big gatherings can be inconvenient. Low water pressure can exacerbate this problem especially in older buildings.

Water purifiers—especially under-sink or RO systems—take up cabinet or counter space. In Singapore’s small kitchens, this can be a challenge.

Countertop units can clutter surfaces while under-sink models require plumbing work.

Neglecting filter changes can lead to:

• Reduced filtration efficiency
• Bacterial growth inside filters
• Health risks

Stay on top of maintenance and some systems have smart reminders or apps to help you track filter life.

Different filters filter different things:

• Activated carbon filters remove chlorine and bad tastes but not microbes.
• UV filters kill bacteria but don’t remove chemicals or sediments.
• RO systems remove most contaminants but at a higher cost and maintenance.

Filters generate waste that’s often non-recyclable. Electronic units use energy adding to your home’s carbon footprint. While purifiers reduce bottled water use they are not entirely green solutions.

Not all purifiers deliver what they promise. Some brands exaggerate their effectiveness or promote unproven health benefits. Look for third-party certifications like NSF or WQA when buying.

With Singapore’s high water quality you may wonder if a purifier is necessary. For many the answer is yes—because of taste preferences, peace of mind or specific household needs.

Check your building’s water quality report or test your water if you’re concerned about contaminants.

If you want to improve taste a carbon filter may suffice. For removing a wider range of contaminants consider RO systems .

Choose models with easy filter replacement and compact designs.
