But why has the Kent water purifier consistently been on top of the list? It is due to its innovative work in the field of RO+UV+UF technology and a brand promise of providing good health over all things.

Why Choose Kent Water Purifier?

Kent has established a strong reputation over several years, thanks to its role in popularizing RO+UV+UF technology in the Indian market. 

If you’re investing in an appliance worth thousands of rupees, you need assurance about the company’s ability to provide after-sales services for at least another year. That’s Kent’s strong point. 

They have a wide service network covering tier-2 and tier-3 towns providing good support to the customers. 

Kent provides a comprehensive purification solution. Most of the standard Kent water purifiers come with a multi-stage water purifying system consisting of a sediment filter, activated carbon, and RO membrane along with UV and UF. 

Considering the unpredictability of Indian water sources (sometimes, high TDS levels in the morning and muddy water in the evening), we need a combination of features. Kent water purifiers come equipped with a TDS controller, enabling them to retain the essential natural minerals present in the water and provide mineral-rich filtered drinking water. 

Although Kent water purifiers are designed to provide a great water purification experience, purchasing one is just the beginning. The long-term cost of owning a water purifier includes factors such as the durability of the filters and availability of customer care centers in your area.

3 Best Kent Water Purifiers in India

1. KENT Grand RO Water Purifier

Best for: Medium-Sized Families with High TDS Water

The Kent Grand RO is known for its reliability, making it a popular choice for big Indian families. With a high purification capacity of 20 liters per hour and 8 liters of huge water storage capacity, we can get a steady supply of safe drinking water for families of 5-6 people. The model includes “Save Water” technology to reduce any wastewater generated during the RO process and is known for its strong and sturdy construction. 

However, its design appears to be outdated and bulky, taking up considerable space on the countertop. It is a basic model focusing on its speed and capacity of water purification, without features like copper or alkaline water quality improvement and smart connected facilities. Additionally, the water purifier’s motor is quite loud during the purification process. Although it serves its main purpose well, its huge size and outdated appearance are major drawbacks.

Regarding the performance, KENT Grand provides effective solutions to remove the challenges caused by hard water (upto 2000 ppm TDS). Users have observed significant improvements in the taste of the water as compared to the water provided by the local municipal corporation. The product is made of high-quality ABS plastic material that is durable and safe.

Pros

• Double purification with RO+UV+UF.
• High storage capacity of 8 liters.

Cons

• Like standard RO purifiers, it does reject a certain amount of water as waste.
• The design is slightly bulkier.

2. KENT Supreme Star RO Water Purifier

Best For: Households wanting to reduce water wastage and maintain tank hygiene

The KENT Supreme Star is an advanced version of the standard Supreme series. It deals with two problems faced by customers—excess water usage and bacterial growth in the storage tank. If you are concerned about the environment or live in a region plagued by water scarcity, this model offers good value for money.

Automatic flushing for RO membranes is an advanced feature that helps to prevent scaling or fouling of the RO membrane by quickly cleaning it, removing impurities from its surface, and ensuring a clean membrane. The benefits of the automatic flush feature include reducing rejected water flow and increasing TDS rejection capacity. This enhances the efficiency of the RO membrane. Also, increasing the lifespan of the RO membrane.

This product comes with a built-in UV LED in the storage tank. Many water purifiers suffer from bacterial growth in their storage tanks, especially when the water sits in them for too long. KENT Supreme Star maintains sterile water in its tank, providing good care to families. 

The alkaline filter helps to enhance the pH level of water. Although the health benefits of alkaline water are debatable, many users feel that it contributes to a better taste and reduces acidity in the water.

However, this model is pricier than others. The presence of a pump also leads to increased energy consumption and slightly higher operational sound levels. If the position of the purifier is far from the water source, it creates difficulties in connecting the reject water line.

Pros

• Reducing rejected water.
• In-tank UV LED light.
• Alkaline water enhancement.
• Sleek and contemporary.

Cons

• Too expensive

3. KENT Supreme RO Water Purifier

Best for: Homes with hard water

The KENT Supreme sits comfortably between the Grand and the Supreme Star. It is designed for users who have very hard water (high TDS).

This model is capable of handling water with TDS levels up to 2000 ppm. This is a critical specification if you live in an area where the groundwater is too salty or hard. Many standard purifiers struggle with such high TDS, but the Supreme is built for it. 

Although the Supreme star works towards reducing rejected water, the classic KENT Supreme focuses on improving hygiene. One key feature of this model is its detachable storage tank. In RO water purifiers with built-in tanks, cleaning the internal portion can be challenging, resulting in the formation of algae or biofilm deposits after several years of use. The Supreme provides the ability to detach the storage tank, clean it thoroughly, and then attach it back.

Fitted with the conventional RO+UV+UF technology and coupled with a TDS controller to provide water that tastes natural.

Pros

• High TDS tolerance of up to 2000 ppm.
• The transparent and stylish body design.
• Multiple purification stages including UV and UF.
• Retains natural minerals.

Cons

• It does not feature the Zero Water Wastage technology.
• The transparent body might need occasional cleaning from the outside to maintain its look.

Look at These Before You Buy on Amazon

Buying a water purifier online is convenient, but we must be cautious. To ensure you buy a high-quality Kent water purifier and not a fake one, keep a watchful eye on the seller providing the product. 

It should be reliable vendors with a history of providing good quality products. Be wary of third-party sellers offering very low prices even if they claim to provide a “dealer warranty.” 

You can also check if Amazon Prime is available. It ensures quick delivery and indicates that Amazon holds the inventory at its fulfillment centers, providing an opportunity to check the quality of goods. 

While checking the features, make sure the water purifier type matches the source of water. If you are drawing water from a borewell, an RO system is a must. If you are supplied with municipal water which has been adequately treated but tastes bad, a UV or UF filter can meet your needs, although an RO unit gives extra safety. 

Carefully go through the details of the warranty provided. Some products come with a basic manufacturer’s warranty, while some sellers may try to sell a seller’s warranty, which is not recognized by the company’s service center. 

Details about installation charges should also be checked. Sometimes the installation cost is included in the purchase amount, and at times you will have to bear the installation charge, which includes paying a technician.

Installation & Maintenance Tips for Kent Water Purifier

As soon as your Kent water purifier arrives, the first step is to install it. Although you may be skilled at handling tools, water purifiers require plumbing and electrical connections that are best handled by trained professionals. 

Many items purchased from Amazon come with complimentary installation demos. Take advantage of this service to ensure that all filters are properly installed and the inlet and outlet pipes are securely fastened. A poorly installed device can lead to leaks and damage to your kitchen cabinet. 

The maintenance aspect contributes the most to the operational expenses of a water purifier. Create a routine to check the pre-filter, a detachable exterior mesh which traps big particulate matter. Cleaning this once a month will enhance the lifespan of the internal filters. 

Knowing when to change the internal filters is very important. Sediment and activated carbon filters need to be replaced after 6-8 months. The RO membrane is costly but can be used for 12-18 months. Don’t wait until the water flow stops or tastes bad to replace the filters.

If you notice that the water flow is noticeably weak, it means that the filters are clogged. Always choose genuine Kent filters for replacement. Buying cheap duplicates can damage the membrane and affect the quality of water.

Kent Water Purifier vs. Other Brands

Brands such as Urban Company and Aquaguard provide sleek designs and advanced digital features at reasonable prices. But Kent water filters are generally large in size, a little noisy, and expensive compared to high-quality affordable options. 

However, Kent’s strong point is its vast service network and wide availability of spare parts—concerns that several other brands fail to address. Therefore, choosing Kent over other brands means giving priority to excellent after-sales service and availability of spares over sleek designs and economical pricing.

Final Suggestions

Choosing the Best Kent Water Purifiers for your home depends on your local water condition and personal preferences.

The KENT Grand RO is reliable, affordable, and can handle multiple water sources with ease. If you’re looking for a simple, effective machine backed by numerous customers’ experiences spanning many years, choose this one. It provides great value for the money we pay for a Kent RO. 

The KENT Supreme Star is ideal for the young and eco-conscious individual. If you reside in a city or village where water conservation is a priority or simply do not wish to waste water, this is a good option. The in-tank sterilizer is a great feature too.  

Kent Supreme offers a nice balance of classic design and efficiency. If you need to remove very high total dissolved solids (TDS) levels and want a classic device to adorn your wall space, this is the one for you.
