Kent Pearl Water Purifier Review

In this review we will cover all the key aspects of Kent Pearl. Let’s go into the detail one by one.

Design & Build Quality

Kent Pearl can be mounted on a wall or you can also place it on table-top / kitchen counter.

I features a transparent water tank. This transparent water tank gives it a decent look and it also gives confidence to the user that the water is pure. This tank is detachable, so that you can remove it for proper cleaning. You do not need help from any professional for opening this tank.

Below the water, there is a sturdy water tap for water dispensing. Ordinary plastics can leak chemical into water over time, but this water purifier is made up of ABS food grade plastic, which is durable and safe.  


Kent Pearl comes with multi stage purification. RO, UV, UF and TDS controller are its most important stages. Let’s see all its stages in detail.

RO purification with TDS Controller

Activated Carbon Filter

Activated carbon filter removes chlorine and chlorine by-products from the water. Municipal water is treated with chlorine and sometimes water contains excess chlorine, which is not good for health. This carbon filter also removes organic compounds that give odour and taste to water, thus making water odourless and taste-free.


Ultrafiltration (UF) blocks remaining physical / visible impurities from the water.

This is an essential step so that water is clean enough to be fed into RO membrane. Unclean water with visible impurities can damage RO membrane.

RO filtration

Kent Pearl comes with decent quality thin film composite RO membrane. It filters heavy metals and toxins such as mercury, led, cadmium, pesticides, arsenic etc. Water is passed with great force through this 0.0001 micron pore-sized membrane to filter ultra-fine particles.

UV Purification

Powerful 11 watt UV bulb inactivates harmful bacteria, protozoans and viruses and from the water so that it is effectively disinfected.

Post Carbon Filter

This filter works as a polisher for the water. This gives water enhanced taste ‘texture’.

TDS Controller

TDS controller is essential feature of almost every RO water purifier because RO purification can reduce the TDS of water by up to 90%. TDS controller makes sure that the TDS of water does not go down from the acceptable limit.

All you have to do it, during the time of installation, just ask the technician to set the desired TDS by adjusting the screw of TDS controller. Healthy TDS level is 150 to 250 PPM. And usually bore-well water has high TDS.

Zero Water Waste Technology

Kent Pearl comes with zero water waste technology, which is effective in saving water wastage due to RO filtration. Regular water purifiers waste 65- 80% water during filtration, but ‘zero water waste’ tech only wastes 50% water. It means it is twice as effective in saving water as compared to regular RO water purifiers.

It is able to achieve this by passing the waste water to overhead tank with the help of internal pump. Thus, water mixes with the water in tank and gets diluted.

Water Storage Tank

Capacity of the storage tank is 8 litres and it is detachable for cleaning purpose. As per our experience, any water tank with a capacity of 7 litre or more is decent enough for mid and large-sized Indian households.

Purification Capacity

Kent Pearl’s purification capacity is a decent 20 litres per hour. It is quite high. This capacity coupled with large 8 litre water tank is more than enough for regular needs.

Auto Flushing System

Auto flushing system prevent scaling or fouling of membrane by rapidly rinsing the RO membrane with water regularly. This increases the life of RO membrane.

Thin Film Composite RO membrane

This film composite membrane is one of the most commonly used RO membranes and it has decent quality.

Hi-Power UV bulb

UV bulb is responsible for deactivating bacteria and viruses. Usually, water purifiers come with 8 watt UV bulb, but Kent Pearl is equipped with 11 watt UV bulb. A stronger bulb means more effective disinfection.

LED Alert System

The alert system of this water purifier contains 2 LED indicators. One is power indicator and other is service indicator. Power indicator lights up when you switch the water purifier on and Service indicator glows when it is right time for servicing.

Built in SMPS

Kent Pearl is equipped with a built in SMPS.  This SMPS works as a voltage stabilizer. Thus, the water purifier is safe from voltage fluctuations.

Fully Automatic Operation

Once you switch on the water purifier, it will automatically start the purification process and will stop the purification once the tank is full. Thus, it is fully automated.


Kent pearl comes with 1 year warranty plus 3 years of free servicing.
