How to Pick the Best Under Sink Water Filters in Singapore

As you start searching for the best under sink water filters in Singapore, you’ll soon realise that it’s a lengthy process that can get a little overwhelming sometimes.

Under sink water filters come in a wide variety of filtration options and a range of prices, so there are lots of factors to consider.

Here’s something that will make it easier for you to find the right under sink water filter for your home.

1. Know what needs to be filtered out of your water

As mentioned earlier, there are different types of under sink water filters sold in the market. Your choice will boil down to what contaminants and particles need to be flushed out of your home’s water system.

The most commonly used among households in Singapore are carbon filter, reverse osmosis (RO), and alkaline.

If you want to get rid of water’s chlorine taste, then a simple carbon filter will end all of your problems immediately. This type of filter will improve the odour and taste of the water.

On the other hand, removing dissolved particles such as sodium requires a more complex water filtration process like reverse osmosis. It’s a popular option because it can make sure that your drinking water is clean, fresh, and odour-free.

Meanwhile, alkaline is a type of filter that utilizes a process known as electrolysis. Water passes through electrically charged plates during the filtration process, separating water into two streams: one is acidic while the other is alkaline.

2. Look for something that’s easy install

Some under sink water filters are harder to install than the others. Most in-line filters only need a basic connection with an adapter, while UV systems and RO systems are more involved and usually need the help of a professional plumber.

A UV system needs an intricate electrical connection, while a reverse osmosis system requires a drain line connection for the rejected water.

It’s worth noting that most under sink water filters require a faucet connection, regardless of how complicated they are to install. Some of the best under sink water filters in Singapore connect directly to a primary faucet or soap dispenser, but others need a dedicated faucet.

3. Consider the maintenance needed

Most under sink water filters need to be replaced once a year, while their membranes last for at least two to three years. If you have poor water quality at home, expect your water filter to have a short lifespan.

If the water contains large amounts of debris and dirt, the filter will reach its full capacity quickly. In this case, you need to replace the filter regularly if it easily clogs… even if you just installed it two months ago.

4. Check the cost of filter replacements

Compared to a whole-house water filtration system, the filters of under sink water filters are significantly cheaper.

However, the need to replace your filters can come more often than expected, especially for those who have poor water quality at home. It’s best to save for replacements to ensure that you always have clean drinking water at home.

Benefits of the Best Under Sink Water Filters in Singapore

Regardless of their type, the best under sink water filters in Singapore have a lot of benefits to bring to any household. It’s no surprise that more and more households in Singapore are dropping water delivery services for water filters.

Let’s go over some of them:

1. Improved water taste

Most tap water has an unpleasant smell or taste, but under sink water filters can flush that out, providing cleaner and fresher drinking water.

The best under sink water filters in Singapore can remove chlorine, fluoride, dirt, and debris that affect how tap water tastes.

2. Safer water to drink

Aside from getting rid of your tap water’s foul smell and odor, under sink water filters can remove a lot of potentially harmful chemicals and contaminants from your drink.

You no longer have to worry about whether or not you’re consuming particles that can be toxic for you and your family. It’s one of the reasons more people are getting their hands on the under sink water filters.

3. Can improve physical development of kids

If you live with children, it’s important to always have clean and fresh drinking water at home. Drinking unhealthy and dirty water can negatively affect the growth of children, stunt their physical growth even.

Some children also get discouraged from drinking water if it has an unpleasant smell and taste. We need to give them reasons to drink more water to meet what their body needs to grow.

4. Cost-efficient

Finally, there’s a huge amount of money that can be saved by ditching water delivery services, bottled water, faucet filters, and freezer filters for the best under sink water filters in Singapore.

If you need to shell out a huge sum of money for a water filter, the price you pay for it gets compensated by its monetary benefits more quickly than imagined.
