Having clean and safe drinking water is essential for our health and well-being. Installing a water filter under your sink is an easy and effective way to do so. This device can effectively remove contaminants from tap water, such as sediments, bacteria, chlorine and lead. You can significantly improve the taste, odour and quality of your drinking water. In this article, we will guide you through the process of setting up a water filter system under your sink.

How is tap water harmful to our health?
Tap water contains contaminants like chemicals, heavy metals, bacteria and other impurities. Consuming tap water may lead to various health issues, such as gastrointestinal illnesses and a weakened immune system.
Which water filter to use?
There are three main under-sink water filter types:
- Single-stage filters: These filters use a single filter media to remove contaminants from the water. The activated carbon filter is a common single-stage filter which removes chlorine and odour from the water and enhances the taste.
- Multi-stage filters: Multi-stage filters use two or more filters, such as a sediment filter to remove large particles, a carbon filter to remove chlorine and a reverse osmosis filter to remove heavy metals and other dissolved solids.
- Reverse osmosis (RO) filters: RO filters use a semipermeable membrane to remove heavy metals, bacteria viruses and many other impurities. They are the most effective water filters but are expensive.
In addition to these filters, there are a variety of other under-sink water filter options available. Some of them are:
- Ultrafiltration filters: UF filters also use a semipermeable membrane, similar to RO filters, to remove bacteria and other contaminants from the water, but they are unable to remove dissolved solids. They are cheaper than RO filters.
- UV filtration filters: UV filtration systems use ultraviolet light to kill bacteria and other microorganisms in the water. UV filtration systems are often used in combination with other types of filters.
How to install a water filter under the sink?
Turn off the supply of water
- Before you install the water filter, look for an area that is easily accessible and provides enough space for the filter system. Remove any items that could obstruct the installation process.
- Turn off the water supply to your sink to avoid any leaks. Find the shut-off valve and close the valve completely. It is usually located beneath the sink or at the main water supply. This will stop the flow of water to the faucet.
- Next, use an adjustable wrench to loosen the connection between the cold water line and the faucet. Open the faucet and release the cold water. To prevent water from spilling out, place a bucket underneath.
Connect the filter
- Now, you need to install the water filter adapter that came with the water filter installation kit. Fit the adapter to the hose and screw it securely to the hose.
- Connect one end of the black tubing of the water filter to the adapter and the other end to the inlet valve of the filter. Make sure all the connections are secure.
- Connect the second adapter to the water shutoff valve and the black tube from the filter to the shutoff.
Run the water and check for leaks
- Now, turn on the water and inspect for leaks. If there are any, tighten the connections or use the plumber’s tape.
- Before using the water from your new filter, it is important to run the water to flush away any loose sediments. Run the water for a few minutes. And now your water filter is ready to use.
FAQs
What is an under-sink water filter?
An under-sink water filter removes contaminants from the water to improve the taste and smell of the water.
How does using a filter help?
A water filter helps to remove the contaminants from the water, makes it safe to drink, and enhances its taste and odour.
Can I install the filter on my own?
Yes, installing the filter is an easy task if followed carefully.
Which under-sink water filter should I use?
It depends upon three factors such as the type of contaminants you want to remove, the flow of water and the capacity.
How do I remove the cold water supply?
Use an adjustable wrench to loosen the nuts of the cold water supply line and remove it.
When should I replace the water filter under the sink?
You should change the water filter if you notice a change in water quality, taste, or odour.
Can I use the filtered water immediately?
No, first run the water to flush away any sediments.
Do I need to hire a professional?
If you're confident about your skills, you can install it yourself. Otherwise, hiring a professional plumber is a good option.
How to repair the leaks?
Tighten the connections or use plumbing tape to seal the leaks.
