In India, wall mounted or table mount water purifier are known from long time because of their feasibility to mount in the traditional Indian kitchen. On the other side, we are adopting foreign kitchen styles with inbuilt drawers, cabinets. These are occupying a lot of space in a kitchen, in addition, water purifier on tabletop or table makes kitchen too congested. To overcome these minimal space problems Indian water purifier companies manufacturing advanced “Under Sink Water Purifiers”.

Under Sink Water Purifiers installed under-the-counter (under-the-sink) or beneath the kitchen sink, thereby saving expensive kitchen space. The installation place makes it unique from other water purifier models. Under Sink Water Purifier is also suitable for connecting with refrigerator with water dispenser tap.
In traditional wall mounted water purifier the purified water from storage tank flows by gravity and water output rate is very low. It almost takes one minute to fill a bottle.
Whereas with an Undersink water purifier, purified water stored in hydrostatic air pressure bladder tank. This tank maintains optimal pressure to give high flow purified water. It's almost 10 to 15 seconds to fill a bottle.
The biggest advantage is you no need to bother about spill water on floor because Undersink water purifier integrated with convenient, high curved tap is fitted on the sink next to main tap, faucet. To fill water, place bottle on the sink and open tap, faucet.
Whereas with wall mount water purifier You need to hold the bottle while filling and need to be careful to water not to spill on the kitchen floor by overfilled water in bottles.

Under Sink water purifiers works as it is wall mount water purifiers works. These water purifiers differ in how they installed, where it install and how they look, but their internal working mechanism is absolutely same. Under sink water purifiers powered by RO, UV, UF, Activated carbon and Sediment filter technologies which are also used in traditional wall mount purifiers.
During Reverse Osmosis (RO) unpurified water passed from semi-permeable membrane by applying pressure on water. During this process chemical, heavy metal particles trapped/stuck in RO membrane, as result gets purified soft water.The only the disadvantage of RO water purifier is it may removes essential minerals like calcium, in your drinking water.
UV or Ultraviolate
In UV purification water passed through the UV light. Due to UV light contaminates, water borne disease causing bacteria, viruses are deactivated. Even though UV kills bacteria and viruses, but their dead bodies still remained in the water, it can be consider as one of disadvantage of UV
UF or Ultrafiltration
It uses hollow fibers. When water feed water passes through the these hollow fibers catches, traps suspended solids and most important, it traps water borne diseases causing bacteria and viruses. This long lasting water purifier works without electricity even can purify muddy water.
It removes dangerous chemical like pesticides present in water and other chemical which makes bad odor. Activated carbon extreme made of porous material traps, catches the disease causing chemicals and bacteria, viruses. Activated carbon has capable to catch chlorine present in municipal supply water and makes water tastes better.
A sediment filter removes mud, sand particles, small pieces of organic matter, clay particles or any small particles. Sediment filter does not remove any chemicals or heavy metal particles.
Undersink water purifier manufacturers take complete responsibility to install water purifier in user home, so user no need to worry about installation. But it's good to know how to install it before you purchase so that you can aware about a water purifier that you are going to buy. Here I am presenting a small video about the installation. As Undersink water purifiers are very new to India, there is not much information available on YouTube. Below video installation process is made in the United States of America. It's almost same as India, the only the difference is pipelines are differing in India from United States of America.
