KENT vs Aquaguard Purifiers For Indian Homes

The quality of water in Indian households is more diverse than we people imagine, and it is not only because of the borewell water in smaller cities. But this is because municipal water in major cities contains varying amounts of dissolved salts, chlorine and bacteria in some cases depending on the age of pipelines and season. 

Since tap water, borewell water, and tanker water may contain different types of contaminants, selecting a water purifier is all about getting the right kind of purifier for the kind of water you have, which makes no sense in selecting any popular brands available in the market. 

This is when KENT and Aquaguard, two most reputable Indian brands specializing in water purification, usually get mentioned together, as both produce water purifiers tailored to the particularities of Indian water specifically.

01

KENT Supreme Plus Alkaline+Copper RO Water Purifier

4.1

₹14599

  • If you have ever felt uneasy about how much water an RO purifier throws away just to give you one glass of clean water, this is really where the KENT water purifier in the model Supreme Plus tries to change the equation. 
  • Instead of letting the rejected water drain out the way most RO systems do, it recirculates that water back to the overhead tank using its own pump, so the wastage that usually comes with RO purification is largely avoided. 
  • On top of that, it pushes purified water's pH up to around 9.5 and adds copper into the mix, aiming for water that is not just filtered but genuinely more alkaline and mineral-supported by the time it reaches your glass.

How Is This Good for Indian Water Supply? 

  • Water across most Indian cities carries high levels of dissolved salts and chlorine residue. 
  • To address this, the added alkaline and copper stages in this water purifier replenish essential minerals that standard RO systems strip away. 
  • Meanwhile, the in-built recycling system directly handles the common issue of excessive RO water wastage.

How Is This Good for Indian Water Supply? 

  • This Aquaguard water purifier is good for the Indian water supply because if your household regularly switches between water sources, whether through seasonal borewell changes or tanker deliveries during shortages.

4.0

₹3999

₹16499

The True Cost of Ownership: Installation, Maintenance, and After-Sales Service in India

Cost & Support Factor

What to Expect

Important Consideration

Installation Charges

May not be included in the listed product price.

Check if the installation is complimentary or not, and whether any additional features such as filter housing and valves are charged separately.

Filter Replacement

Recurring cost every 6 to 24 months, depending on the filter type.

The harder the water with higher TDS, the sooner the filters get blocked leading to regular and expensive filter changes.

Service & Support

Major brands (KENT, Aquaguard) have wide nationwide networks.

Response times of local technicians differ, and also the availability of parts therefore, always confirm your pincode before purchasing.

Making the Right Choice: Key Factors for Your Specific Indian Water Needs

Measure TDS Level First: 

  • Nothing is more important than measuring the TDS level of your water source using a TDS meter. 
  • This figure will automatically eliminate the water filter models that either do not have enough power for hard water or too many features for soft water.

Consider Your Family Size: 

  • Be honest when determining how much you use water at home. 
  • A tank of 8 liters is sufficient for smaller families, but it’s drained quite quickly in big ones with intensive usage.

Compare Features With the Budget:

Basic Model: Those who are budget-conscious and require only filtration can opt for basic models.

Extra Value: For those families that value minerals or the longevity of tanks, the additional features’ cost is well spent.

FAQ's

  • Is RO water necessary for all Indian water?
    No, not necessarily because RO technology is made for high TDS water. The use of RO technology on low TDS water will remove the minerals from the water unnecessarily. Moreover, the water wastage will also be high in this case. therefore it is better to know the TDS content of your water supply first.
  • What is the recommended frequency to replace filters in a water purifier in India?
    The filter life may vary from 6 to 24 months, and the exact period largely depends upon the total dissolved solids in your water source and the volume of water you consume every day. Water with a high concentration of solids/sediments consumes the filters faster.
  • What is the real distinction between mineral retention technology and copper infusion technology?
    The principle behind mineral retention technology is the mixing of a little amount of the unfiltered water with the filtered water to keep natural minerals that the process of RO filtration would have filtered out. In contrast, copper infusion technology involves adding copper to the water during filtration, which is a different process from retaining minerals that were originally in the water.
  • Which brand provides good services along with spare parts in small towns of India?
    The performance of a service usually depends on the exact geographical location rather than the brand because both the brands have decent networks in Indian cities and towns. It really does make sense to verify the location-wise service centre information along with the experience of recent customers from that particular pin code.
  • Can the purifier take care of water with extremely high TDS content from the borewell?
    Most of the purifiers that use Reverse Osmosis technology can take care of relatively high TDS quite effectively; but at the same time, every purifier has its own maximum permissible TDS level, which should not be exceeded to achieve optimal results. It would be better to measure the TDS level of the borewell water yourself and compare it to the rating of the purifier.
