What makes water filter an important commodity?

The water supplied directly to our homes through various sources has a large number of impurities present in them. The various sources from which we get water to our houses include-

• Tap water - impurities like bacteria, cyst, rust, and chemicals as well as dissolved salts are present in the water flowing through the taps.
• Bore well - the most toxic and deadliest of chemicals and metals like fluoride, arsenic and lead as well as many dissolved salts are bound to be present in the water supplied through bore well.
• Overhead tanks - chemicals, biological impurities and heavy metals contaminate the stored water above in the tanks.

At this level, the water is polluted because of the increasing discharge by the industries without treating the waste before discarding it. The water is filled with so many chemicals present that simple boiling is not sufficient. Water filters along with the bacteria and virus help to remove the dissolved impurities as well.

These filters now use a double purification technology of RO+UV+UF+TDS to ensure that water stays in its purest form. The water after being purified through such efficient technology might reduce the essential minerals as well from the water but this revolutionary technology makes sure that water is not only pure but healthy for consumption too. The essential minerals present in the water are still retained after removing all the particles and impurities present in it.

These filters certainly play an important role in our households. They play a major role in keeping the family healthy. The water purifier is designed accordingly that it can be mounted on the walls of your home kitchen or office. Water purifiers also have the added advantage of being portable which is greatly beneficial for those who travel a lot since it does not require electricity or running water for the purification process. There is also another type of filter with inbuilt RO purifier and chiller, which gives access to pure as well as refreshing cool water. During summers, the water filters become even more important as the presence of impurities is high as well as the consumption level of water is also more during these months.

The portable water purifiers help in the clean India campaign and help conserve our planet. Take for example of you and your family or friends going for a picnic or trekking on the weekend. Water in large quantities will be needed. Buying water bottles will not only burn a hole in your pocket, the plastic bottles when empty, litter around causing filth. These plastic bottles also pollute the environment when burnt or not disposed of properly. Kent is renowned in the purification sector and is continuously developing its technology, dedicatedly trying to provide the best drinking water possible. Their contribution in the purification and keeping and protecting the families have played a huge role.With the indispensability of drinking clean water on a rise, investing in filters has become crucial to us.

Why use a water purifier?

According to studies, 70% of the country’s population lives, is routinely contaminated with toxic and bacteria. Every year, about 600,000 Indian children are affected by diarrhea or pneumonia, often caused by toxic water. Lack of clean water has even gone beyond affecting the health of Indians. 

Water is contaminated with impurities, salts, fluorides and even dust and even with dirt at time.  These days even fresh water is not safe to drink. It needs proper purification before consumption. 

Water is an essential commodity, which is used for drinking, cooking, washing and many similar purposes. It is very necessary to purify water before consuming it in any way. Water purifiers are becoming handy for this purpose. 

Water Purifiers:

The concept of water purification through reverse osmosis is not very old and is fast gaining popularity due to its various advantages. Water Purifiers are essential kitchen appliances, which clean and soften water by the process of reverse osmosis. 

Water is made to pass through various filters and these filters work to remove all possible impurities to purify and soften the water. The only drawback of reverse osmosis is that it deprives water of all possible minerals, as it can’t differentiate between the good and the bad. 

Advantages of water purifiers:

KENT-GRAND-PLUS

Electric water purifiers such as Kent’s mineral RO are capable of eliminating suspended as well as dissolved impurities. This is because they use a combination of RO+UV+UF+TDS technology to purify water. 

Water purifiers like Kent’s Mineral RO helps to control the TDS level in water. 

Bottled water is very costly. Water is not filtered in front of its user, so there is no guarantee of its quality. Users are not sure of proper cleaning of bottles as well. 

With water purifiers, users have added advantage of getting unlimited supply of safe drinking water making it easy to consume and ready to use. Use this water for cooking and drinking. 

It saves money and energy, both. Since bottled water is costly so installing water purifiers has reduced their cost tremendously. Also lifting big bottles requires lot of energy. Therefore, users can save upon both money and energy. 

The most important part of water purification is of supplying healthy and safe drinking water at affordable prices and that too with ease. 


With the facilities of online shopping gaining popularity, many brands have started selling water purifiers online. This helps the consumer choose between the different brands, water purification technologies, etc.

Decoding the best RO water purifier

It is a well known fact that water is essential for our survival.  According to researchers, the Earth contains about 70% water. Only a small portion of this huge percentage is actually fit for consumption, which is not enough for us. Availability of clean drinking water has become a luxury for us and it is imperative that we do everything in our power to conserve it. Water which comes from a conventional source comes with a lot of risks and health hazards because it contains some impurities like nitrates,  phosphates, heavy metals, microorganisms and dirt.

The first and most obvious benefit of having a water purifier is that it will eliminate the impurities that can damage your health. Water which goes through a purifier will contain lesser bacteria, fewer heavy metals and lesser chemical pollutants as compared to water that comes straight from the tap. Technology has gifted us many inventions that have made our life easier, simpler and flexible. Reverse Osmosis water purifier by Kent too is a gift of technology. It is an eco-friendly water purifier that saves water on the go. It is widely considered as the best RO water purifier in India.

Reverse osmosis technology pressurizes and passes impure water through a semi-permeable membrane. RO technology is probably the best purification technology known to mankind. It effectively removes all harmful micro-organisms such as bacteria, viruses and cysts. When it is used in combination with other filters (sediment and carbon), it successfully removes all other suspended impurities from water including dissolved gases and organic impurities.

The biggest advantage of this technology is that it is able to remove more than 99% of dissolved impurities such as chemicals, rust, salts of heavy metals, pesticides and insecticides present in water. In fact, RO is the only affordable technology that can remove dissolved impurities from water.

RO technology removes substantial amounts of most inorganic chemicals such as salts, metals and

minerals; micro-organisms and various organic chemicals. The quality of the membrane and the pressure of the water helps in determining how effectively the water separates form these contaminants.

However, RO devices have a drawback. Their process is so efficient that all the dissolved salts (minerals) from the drinking water are filtered out, including the essential ones necessary for our body. Water purified through only RO technology is distilled, has a bitter taste (because of no essential minerals) and has pH value lower than 7 - making it slightly acidic.

Further, RO technology uses a very fine membrane which has a pore size of 0.0001 micron. The process requires raw water to be forced at a very high pressure so that water passes through the small pores of the membrane, preventing bacteria, germs and other impurities from passing through. However, due to variation in day and night temperatures, high speed and pressure, some of the pores of the membrane get enlarged after a few months of continuous use. Thus, allowing harmful micro-organisms to easily pass through it and thereby making the process ineffective in the long run.

Kent has come up with a unique solution for this problem – the ‘Kent Mineral RO’ water purifier. This water filter uses a combination of RO+UV+UF+TDS to provide the cleanest water possible. Other innovative products by Kent include portable water purifiers, Tap guard, etc.

What Makes Your Water Contaminated

Water-caused health problems are mostly due to inadequate and incompetent management of water resources. Water is contaminated mainly due to inflow of sewage into the source. Across India, unsafe drinking water and poor sanitation and hygiene are the main contributors to an estimated million cases of diarrhoeal disease, primarily increasing the number of affected people every year.

In urban areas, water supply pipelines and open drainage channels running side by side put the safety of drinking water at stake. The municipal authorities are unable to treat the increasing load of the municipal sewage due to which it may end up contaminating water bodies.

Major pathogenic organisms that are responsible for waterborne diseases in India are Bacteria, Virus and parasites. Poor waste disposal facilities also contribute to pollution of water bodies by means of leaching.Microbial pollution in water is also responsible for disease burden.

These pathogenic organisms are transmitted mostly due to contaminated water, improper sanitation and poor hygiene practices exacerbated by large volumes of untreated sewage generated daily in major cities.

In the rural areas, due to the widespread practice of open defecation and poor operation and maintenance of water sources, microbial contamination occurs in surface and groundwater bodies.

Having a water purifier at home has become a basic necessity to consume contaminant free and hygienic water.

Best Water Purifiers Ideal for India’s Water Conditions

Access to hygienic water is still a big challenge for many in the country. It is a must to purify water using domestic RO water purifiers in every household to prevent the onset of waterborne diseases. RO water purifier is capable of eliminating contaminants such as arsenic, fluoride and heavy metals.

Kent RO systems Ltd. is the only brand providing low cost solutions so that such devices can be offered at very affordable price.

Kent offers an extensive range of low cost water purifiers with a combination of technologies along with the addition of TDS (Total Dissolved Solids) control valve which allows you to retain essential minerals to ensure you with safe and healthy drinking water.

In the case of water purification industry, laboratories of international repute, like NSF, WQA and more recently ISI, have certified Kent products for its quality and efficacy.

Review Of RO Water Pufiers

Water purification systems are in great demand today. Factors such as climate change and pollution have made the water that we consume unfit for consumption.

The most important factor in a water purifier is the technology that it uses. The most used water purification technology is the Reverse osmosis (RO) purification technology.

Reverse osmosis is a proven technology that has been used successfully on a commercial basis. One of the better known uses of RO is the removal of salt from seawater. Reverse osmosis units remove many inorganic contaminants from household drinking water supplies. The removal effectiveness depends on the contaminant and its concentration, the membrane selected, the water pressure and proper installation.

The semi-permeable membrane used in reverse osmosis contains tiny pores through which water can flow. The small pores of this membrane are restrictive to such organic compounds as salt and other natural minerals, which generally have a larger molecular composition than water.

These pores also restrict bacteria and disease-causing pathogens. Thus, reverse osmosis is incredibly effective at desalinating water and providing mineral-free water for use in photo or print shops. It is also effective at providing pathogen-free water.

In areas not receiving municipally treated water or at particular risk of waterborne diseases, reverse osmosis is an ideal process of contaminant removal. RO systems are used in two applications - industrial and household water treatment

Advantages of RO System:

1. Very convenient for commercial usage, as a much higher percent of water is recovered.

KENT - Pearl Purifier

2. Useful for places where there is a serious shortage of fresh water.

Disadvantages of RO System:

1. Water purified through only RO technology is distilled, has a bitter taste and has pH value lower than 7 which makes it slightly acidic.

2. RO technology uses a very fine membrane which has a pore size of 0.0001 micron. The process requires raw water to be forced at a very high pressure so that water passes through the small pores of the membrane, which blocks the bacteria, germs and other impurities from passing through. However, due to variation in day and night temperatures and high speed pressure, some of the pores of the membrane get enlarged after few months of continuous use, allowing harmful micro-organisms to easily pass through it, thereby making the process ineffective in the long run.

Kent has come up with mineral Ro technology that has all the advantages of Ro water purifiers but not the disadvantages. Kent mineral RO uses a combination of RO+UV+UF+TDS control system to provide the cleanest water possible. No wonder that it is being as the best water purifier in India.

The Best Water Purification Method In India

Contaminated water is affecting the health of a lot of people in India. Diseases such as diarrhoea, cholera and other waterborne diseases are prominent among those who consume contaminated water.

Industries, use of fertilizers and pesticides, global warming and poor water transportation are factors that lead to contamination of water. To counter this grave problem, purification of drinking water is strongly advised.

We decided to shed some light on how to purify water.

KENT Water Purifier

1) Boiling: This is perhaps the oldest method used to purify water. Boiling water ensures that many diseases causing germs are removed from water. However, this method is ineffective on suspended impurities and metals like lead. This method also leads to pollution as wood or fossil fuel is burned to boil the water.

2) Chlorine: The use of chlorine to purify water is prominent among municipal corporations. The effect of chlorine is, however restricted to only a few contaminants. The use of chlorine also leaves a bad taste in the water.

3) UV based water purifiers: This method is very helpful in the process of eliminating microorganisms from drinking water. The UV rays emitted by these machines suspend the presence and growth of bacteria and viruses. However, many suspended impurities remain unaffected by the UV based water purifiers. To make the UV water purifiers more effective, it has to be used in combination with other water purification technologies.

4) Reverse osmosis (RO) based water purifiers: Probably the most known method of water purification today, RO based water purifiers are very efficient in removing contaminants from drinking water. The tiny pores in the membrane of the RO water purifiers blocks suspended as well as dissolved impurities. This technology also had a drawback just like the methods mentioned above.
The TDS in water remains uncontrolled and hence leaves a bad taste in water. You also require water at a specified pressure in this method to aid purification.

All the above mentioned technologies are efficient to purify water, but they also have some drawbacks. Kent, a brand that is committed to raising the bar of innovation in the water purification sector came up with a technology that has all the advantages of the above mentioned technologies but not its drawbacks.

The Kent mineral RO is a purifier that uses a combination of RO+UV+UF+TDS control to disperse the cleanest water. This innovative machine is capable eliminating both suspended as well as dissolved impurities while retaining the necessary minerals. This machine also improves the taste of water. With all its features, it is no wonder that Kent mineral RO is among the top 10 water purifiers in India.

Safe Drinking Water - Current Scenario

We tend to take the availability of our drinking water as a right, and for a good reason. A lot of people in India, have access to drinking water than ever before. However, a question that arises is, how safe is our drinking water really?

This question is both timely and impervious, considering that numerous water borne disease have safe drinking water has been hampered by many factors; a few of them are listed below.

wrecked a havoc in the modern society. The availability of

1) Urbanization: The last few decades have witnessed a dramatic population increase. This has increased the demand for clothes, housing and food. As more cities and towns are being built, farmers have increased the use of fertilizers to produce more food. These fertilizers seep through the soil as contaminate water bodies. The increase in construction activities, increasing discharge chemicals from industries to produce more materials has also done a great deal of damage to our water bodies.
2) Untreated sewage: Sewage, garbage and liquid waste of households and factories are discharged into rivers and lakes. Harmful chemicals and toxins which make the water poisonous for aquatic animals and plants are present heavily in this untreated water.
3) Dumping: Dumping of solid wastes in water bodies causes huge problems. Waste includes glass, plastic, Styrofoam, etc. Different things take different amount of time to degrade in water. They affect aquatic plants and animals as well as contaminate the water, making it unfit for consumption.
4) Industrial Waste: Industrial waste contains pollutants like lead, asbestos, petrochemicals and mercury, which makes it extremely harmful to both people and the environment. Industrial waste is discharged into lakes and rivers by using fresh water, contaminating the water.
5) Oil Pollution: Sea water gets polluted due to oil spilled from ships and tankers while travelling. The spilled oil does not dissolve in water and forms a thick sludge polluting the water.
6) Acid Rain: Acid rain is caused when the air pollution mixes with rain. The acidic compound, which is a result of air pollution, mixes with water vapor and results in acid rain. This acid rain contaminates the water bodies making it unfit for human consumption.
7) Global Warming: Due to global warming, an increase in water temperature has been witnessed. This increase in temperature, results in death of aquatic plants and animals. This contaminates the water bodies.
8) Poor supply methods: Ageing pipeline network and poor maintenance results in municipal water getting contaminated by the time it reaches our homes.

The constant deterioration in the quality of water and rise in impurities, it is now imperative to have a water purifier in our kitchens, irrespective of the source of water supply. The current scenario is such that, water that is supplied by local government bodies or obtained from natural water bodies, are unfit for direct consumption. Water purifiers ensure that, the water we consume is free from impurities that may otherwise, be harmful.
