Here, I have highlighted the differences so that you can find the differences easily. It is interesting to note that as far as specifications are concerned, both the water purifiers are very similar. Major differences are that Kent Pearl comes with a detachable water tank and Zero Water Wastage Technology. However, the tank capacity is slightly lower in Kent Pearl.

Let us first talk about similarities and then we will discuss the differences between Kent Pearl and Kent Grand Plus.

Key Similarities Between Kent Pearl and Kent Grand Plus

Purification Technology

The purification technology of Kent Pearl and Kent Grand Plus is the same. It comes with 7 stages of purification. Let us see what are these technologies.

Stage 1 – Sediment Filter

Sediment filter filters out larger impurities such as sand, dust etc. It makes the water purifiable by more advanced filters.

Stage 2 – Activated Carbon Filter

Once the large impurities are removed, the water is passed through activated carbon filter. Activated carbon absorbs chlorine and organic impurities from water.

Sometimes the excess chlorine and its by-products remain in the water after it is treated with chlorine for disinfection. Activated carbon efficiently removes these from water. Also, it removes organic impurities that cause bad smell/taste in water. This makes the water drinkable.

Stage 3 – Ultrafiltration (UF)

In the next stage, water is allowed to pass through a UF membrane. This UF membrane filters bacteria, some types of viruses and suspended solids from water. It also purifies water so that the water does not harm the RO membrane.

Stage 4 – Reverse Osmosis (RO)

RO is the most effective purification process. When water is passed from the RO membrane with great force, only water passes through it, while small impurities are filtered. It filters salts, minerals, toxic heavy metals, pesticides and so on.

Stage 5 – TDS Controller

Because RO filtration is so powerful, it removes even essential trace metals such as calcium and magnesium. Hence, a TDS controller is needed. Here, slightly impure water from UF is added onto the RO water so that the minerals are added back to the purified water. This is why we always recommend buying an RO water purifier with a TDS controller.

Stage 6 – Ultraviolet Filtration (UV)

UF purification is one of the last stages. Here the water is passed through a UV lamp/bulb. The UV-C radiation coming out of the lamp kills bacteria and viruses effectively.

Stage 7 – Post Carbon Filtration

The seventh stage of water purification involves post carbon filter which adds shine to the water and removes any remaining inorganic impurities.

In-Tank UV Disinfection

Both the water purifiers come with in-tank UV disinfection. This means that the water gets continuous UV purification while the water is inside the tank. This is a great feature because the germs can multiply even when the water is stored in the tank. Also, not many models come with this feature.

Purification Speed

The purification speed of these water purifiers is 20 litres per hour. This is one of the highest in RO water purifiers. It is also quite good and more-than-sufficient speed for most of the households. Considering the tank capacity is 8 to 9 litres, the water tank will get full in 24 to 27 minutes, which is great.

Retains Essential Minerals

As discussed, this water purifier retains essential minerals with the help of a TDS controller. This makes the water healthy for both mind and body.

Maintenance Cost

Since the filters used in both the water purifiers are similar, the maintenance cost is also the same for each of them.

Sediment filter, UF, activated carbon and post carbon filter each come at a price range of 1000 – 1500 rupees. And RO membrane usually comes in a price range of 2,000 to 2,500 rupees. Each of these filters should be replaced once every year.

Differences Between Kent Pearl and Kent Grand Plus

Detachable Storage Tank

One of the main differences between Kent Pearl and Kent Grand Plus is that Kent Pearl comes with a detachable storage tank. This makes it easy to clean the tank. However, you will still have to use a screwdriver to remove the tank from the unit.

Zero Water Wastage

Zero Water Wastage is the name of the technology designed by Kent to remove the biggest drawback of RO water purifiers and that is water wastage. RO water purifiers waste 60 to 70% of the water that gets removed in form of RO reject water through the reject water pipe.

To prevent this, Kent has introduced Zero Water Wastage technology that reduces water wastage. The water wastage with this technology is around 50% instead of 60 – 70% in regular water purifiers.

How does this work? Well. The reject water is pumped back to your home water tank and gets mixed and diluted with the water in this tank. This is possible with the help of an internal pump that pushes the reject water back to the overhead tank. Please note that it works well if the tank is placed on the 10th floor or less. Else, you will have to install an external pump or talk to your technician.

Kent Pearl comes with ZWW (Zero Water Wastage) technology. Kent Grand Plus comes in two models. One with ZWW and another one without this technology.

Tank Capacity

The tank capacity of Kent Pearl is 8 litres, while Kent Grand Plus comes with a 9-litre tank capacity. This difference is not huge. Also, because the purification speed is similar, it will take less than 30 minutes to fill the tank in both the cases. Hence this is not a significant factor to consider.


Kent Pearl and Kent Grand Plus have different designs. Kent Pearl comes in a transparent water tank that makes it easy to view the water level. The filters are hidden behind the water tank, which makes the design more pleasing. On the other hand, Kent Grand Plus comes with a white water tank that is not detachable. Also, the filters are visible behind a transparent cover. This is a bit traditional design. However, there is no difference in the working of the two purifiers because of different designs.

What Do Customer Reviews Suggest?

Kent Pearl is rated ‘very good’ or ‘excellent’ by more than 85% of customers on all the e-commerce stores combined. Similarly, for Kent Grand Plus, more than 86% of customers rated it ‘good’ or ‘excellent’ across all the e-commerce stores in total. Most negative reviews are about either defective products or bad service quality. However, customer satisfaction is above average when compared to many other RO models.

This clearly suggests that customers are equally satisfied with both the water purifiers.
