These days, you can see the RO Water Purification system in almost every household in India, especially in the urban cities.
And, while the wall-mounted water purifiers are used by most people, there is also another type of purifiers known as under sink water purifiers.
These are actually considered by the people living in urban areas with smaller kitchen spaces.
What is Under Sink Water Purifier?
Under sink or under counter water purifiers are similar to the normal RO purifiers but can be installed under the sink counter instead of wall mounting.
These are designed to be installed with built-in sinks in the modern kitchens as an attempt to hide the purifier and keep the kitchen interiors minimalist.
Types of Under Sink Water Purifiers
The under counter water purifiers come in two types – one with inline filters and another with regular filters.
These inline filters come with a single cartridge and are installed using the push fittings along with your regular water source.
Though the installation is a bit difficult, they let you use your sink tap on while the water flows through the purifier.
These are regular filters that require a separate or dedicated filter tap. You can use a T-connector to install the second tap for the filtered water.
Whatever the filter type you choose, ensure that you buy the best under sink RO purifier with TDS controller at any cost.

How to change the filter under my sink?
It is the same as you do with your wall mounted water purifiers. Just remove the cabinet and plug-out the filter connections before taking the filters out of the system. Replace them with new ones from the same brand to ensure proper functioning of the water purifier.
