Kent Supreme Vs. Kent Grand Plus
by| Last Updated
So you’ve decided to get that water purifier for the home, which should be the best one in the market.
When it comes to Kent water purifier, they have been in the market for quite some time now and they are the one pioneered in bringing the Reverse Osmosis (RO) based filtration to the Indian market.
They offer a wide range of healthcare products ranging from air purifiers to kitchen appliances.
We are going to compare two products from the Kent range of water purifiers which are priced almost closely and hence in order to clear the confusion and you can choose which one to go after, based on your requirements.
Before diving into the comparisons, let’s first understand the technologies that are used within these purifiers.
Technologies used in Kent Supreme and Kent Grand Plus
Pre-filter: This filter is used to screen out large sediments. It can be seen in some of the premium water filters.
Sediment filter: This the initial filter (general) through which the water comes in.
Almost all water purifiers will have this stage as it is necessary to filter out the sediments which come in with the municipal water.
And having this filter in place extends the life of the other filters which are present inside your purifier.
RO (Reverse Osmosis) membrane: A membrane with a micron rating up to 0.2 microns which removes all the other dissolved salts and hard water elements.
TDS Controller: TDS (Total Dissolved Salts) are inorganic salts present in the water such as potassium, calcium magnesium etc. We can check the TDS levels using a TDS detection device.
Usually, the TDS levels in the municipal water are exceedingly high and can affect the health in the long run if it is not controlled. So the addition of this feature is a major plus.
Post carbon filter with added mineral cartridge: It is responsible for the addition of essential nutrients which were lost during the filtration process.
UV Disinfection: By passing the water through a series of UV radiation, it kills all the bacteria and viruses present in it.
All these filter and technology may not be present in the budget offering of Kent and other manufacturers.
More the number of filters higher will be the maintenance cost of the water purifier, but the water that you get at the end is of the finest quality which makes it all worth it.
Another plus point which comes with such kind of premium water purifiers is that they provide the free installation and extended warranty in some cases.
And a good quality water purifier rejects some water which is not purified, this can be reused for other purposes inside the home.
The design is another aspect that we need to consider when it comes to these products.
Both these products come with transparent and opaque body and are white in colour.
All the filters are visible from the outside which makes it even more sophisticated.
You can make use of this detailed video by Dr. Mercola to learn further about water purifier filters here:
Since we have covered some ground with info on water purifiers, let’s now compare them in all aspects, which will help you decide on which to get.
To make the comparison simpler, you can refer the table below. All the important specifications of these two water purifiers have been captured here.
No water wastage + 9 litre purified water storage
|1 year +|
|Yes||Yes||Yes||8L (pure)||1 year +|
This offering from Kent comes with 18 litres of storage capacity where 9 litres is for pure water storage and 9 litres of rejected water and the body is a mix of both transparent and opaque housing which houses the filters and the storage tanks.
The outside tank is chamfered on both the sides to give those sharp aesthetics to the purifier.
The company offers 1-year warranty and three years of no service cost with this product.
Since this is one of the premium offerings from Kent, it includes almost all major water filtration stages such as Reverse Osmosis (RO), Ultra-Filtration (UF), Ultraviolet Filtration (UV).
Let’s go through all the filtration stages of the Kent Supreme Water Purifier:
Sediment Filter: The municipal water will contain a large amount of sand and slit in it, which can cause a threat to not only yourself but also reduce the lifespan of the filters, which are present inside the water purifier.
Activated Carbon Filter: This filter is a cartridge full of carbon powder which is having high absorption capacity.
This absorbs all the major toxins and dissolved in the water and the carbon particles which may get added to the water will not be absorbed by the body, but in turn helps removes toxins inside your body!
Reverse Osmosis Filter: This helps with removing the dissolved salts present inside the water.
It consists of a semi-permeable membrane which only lets water molecules and minerals up to a certain size pass through.
This makes it one of the most efficient filters to have inside a water purifier, but this is filter uses power for its working as it forces water to pass through the membrane.
This helps in removes impurities of pesticides, detergents, chlorine, fluorine etc.
Ultra-Filtration: Filtrations which can screen up to 0.02 microns and more are called as Ultrafiltration stages.
They are used to remove the turbidity in the water, meaning removing the colloidal particles present inside the water.
It also removes the bacteria and cysts present in the water.
UV Filter: The UV filtration is done using a UV (Ultra Violet) bulb and these high intensity light will actively kill the bacteria and viruses which is present in the water, leaving you with pure water which is completely safe of drinking.
This purifier comes with the TDS controller which is helpful in areas with high TDS (Total Dissolved Salts).
Let’s learn a bit more about TDS.
TDS Controller: TDS (Total Dissolved Salts) gives the measure of the dissolved inorganic salts such as calcium, phosphates, nitrates etc.
Having TDS levels less than 300 mg/l is ideal for consumption whereas greater than 1200 mg/l is totally unacceptable.
You can check the level of TDS in your eater by using a TDS detector meter.
It is essential that you test these levels without the purifier and testing it again after fitting the water purifier. Therefore, having this controller will definitely help you in cleansing the water.
In this water purifier there is an alarm which notifies the user about the filter change so that there is no worry about when to change them.
This product is tested and certified of the highest quality standards by NSF International, they are an independent American product testing and certification centre and the Water Quality Association.
Make sure that, when you get the product, do check the labels for these certifications.
The computer controlled reverse osmosis recovers water greater than 50% which is a big deal, and this recovered water will be stored in a separate tank which, you can obtain from a separate pipe and use it for other purposes.
The purifier has a purification capacity of 20 litres per hour and has max duty cycle of about 100 litres/day.
They have a pan India service network and you call the representative from the number which is provided on the label itself for service as well as for installation.
For those who are looking for a water purifier which can take care of the needs of a 4-5 membered family that too with little maintenance and for those areas where there is water scarcity, this purifier will ensure high quality of water with minimum wastage.
Another giant from the Kent stable of water purifiers is the Kent Grand Plus.
There is a few key difference between these two, hence the price difference.
The Kent Grand Plus has about 8 litres of just purified water storage and there is no separate tank for the rejected water storage.
This water purifier has the same number of filtration stages as the Kent Supreme.
This has a storage water level indicator when compared with the Kent Supreme.
The product comes with 1 year of warranty and 3 years of no service cost.
The body is made with the highest food grade plastic (ABS) and all the purification stages are completely computer controlled, it notifies when there is a filter change and when the UV lamp goes out.
This product also is NSF and the water quality association.
The box comes with the water purifier, installation kit, and the manual.
Another feature called as ‘auto flush’ removes the water present inside the filters in a forced manner so that it can clean itself. This drastically increases the life-time of the filters.
But Kent Grand Plus is having a normal RO filter which will have some wastage of water, i.e. more than that of the Kent Supreme as the latter one is a ‘no wastage’ RO filter.
Keeping all these points in mind, the Kent Grand Plus water purifier is for those who don’t mind the additional wastage of the unpurified water (which otherwise could have been used for cleaning purposes).
You can now compare the features and other points between these two water purifiers.
There is not much big difference between these two purifiers except for the 1 litre higher capacity and water storage options in Kent Supreme, and water-level indicator in Kent Grand Plus.
What I would suggest the person reading this article is that, by now you would have understood the difference between the two products, now compare the requirements for the home and go for the one that suits you and your family.
