Here I am comparing two water filter products of same brand, Kent, in which one is already released and the other is released today.

We all know that there is a need to conserve our existing resources. In that, water is the first thing to conserve for future purposes. Generally, we boil the water in the rainy season to kill bacteria and virus. But, the dissolved impurities are in the water only. To remove that, long back, we used water filters to purify water. But, we need to clean the cartridges whenever they fill with bacteria/viruses. To overcome the disadvantages of water filters kent came with a product called water purifiers.

The following are the differences/ comparisons between already existing product Kent Grand water purifier and newly released product Kent RO Supreme with its working process, specifications, features, price, availability and all.

Working process in RO technology

When the water purifies is starts working then raw water will enter into the RO tanker. In RO tanker, the dissolved impurities are removed. Dissolved impurities are fluorides; pesticides etc. and the dirty water came out with another pump. After that, water enters into UF chamber and TDS controller. In the UF chamber, any bacteria & Cysts are there, those are removed here and passed to TDS controller. TDS controller retains essential minerals and then water comes into UV chamber. In the UV chamber, double purification will be done. Here, any missed bacteria & viruses are in the water that is totally killed and gives the 100% pure water to us.


Both are having a transparent covered body. With this, you can view and know the water levels. The body is constructed with ABS (Acrylonitrile Butadiene Styrene) thermoplastic material for injecting so there is no need to talk about rusting. The cartridges used in kent grand are: Sediment, Activated carbon, UF and post carbon and the kent supreme has Sediment, Carbon block filter; UF and RO filters are used. Kent Grand and supreme both are space makers by designing with 400 X 250 X 520 mm and 430 X 270 X 630 mm dimensions with a weight of 9kg and 10.900 kgs respectively.

The RO purifier capacity per hour is 15 litres and per day it purifies up to 75 litres, in both products. You can mount this appliance on the wall. By doing this, you can save space in the kitchen and looks neat. Kent grand contains push-fit components to avoid wastage of water. Whereas in Kent Supreme contains two storage tanks to reuse the wastage water for other purposes. In the supreme appliance, double purification is done (first on RO and second through UF and UV purification). Using of TDS controllers in-built in the appliance we can get the natural minerals in the purified water.


Double purification is done by RO and UV, UF TDS controller whereas in Grand Double purification is done by RO and UV only with the help of TDS controllers. For leakproof performance, push-fit components are used in Grand, whereas in supreme, double storage tank are used. Supreme purifies 0% water wastage and Grand purifies with a 3/4th of water wastage. Maintains essential minerals and removes salt/sweet, bacteria, viruses, dissolved impurities etc. In Grand, if UV stops functioning, then there is no assurance for giving pure water. In supreme, there is an automatic alert for filter change whenever needed, whereas in Grand we need to set alarm for changing the filter. If UV stops functioning then there is an alert and UV fail alarm will ring. UV lamp should be replaced otherwise it won't give purified water. Purifies all types of water like tap water, bore water, bore-well water etc.

A very detailed and exhaustive article by the author on these particular water purifiers.

Clean water is the necessity in our household and day by day new models and new technology is bringing in new type of machines in this segment.

Now the problem is that we are already having water purifiers mounted in our house, albeit an older model, that are in fact giving good service and we cannot replace them so often as it involves expenses on that account. So we have to first use our old machine optimally and then only go for a newer version or newer technique.

These costly gadgets have another expense associated with them and that is the annual AMC charges which are also high at about 15-20% of the price of the item. So that should also be taken into consideration when going for a high priced machine.
