Air purifiers at a glance

It is a well documented fact that indoor air is more polluted from the air outside. This may be because of the fact that homes or offices today are virtually sealed to make use of air conditioner or heater more efficiently. This stops fresh air from circulating inside.

While some pollutants like pollen come from outdoors, some pollutants are created indoors itself. Carbon monoxide, for example, is usually the result of heat combustion produced by furnaces, cigarettes or auto exhaust. Cooking vapour is another such example of pollutant created indoors.

Here are other pollutants present in the air -

1) Microbes: Germs, Viruses, Bacteria and mould spores
2) Odours: From cigarette smoke, cooking and pets
3) Gases and Chemical Fumes: Chemical fumes from wall paint, formaldehyde, nail treatment products, etc.
4) Particulates: Allergens, dust, dust mites, pollen, particles in smoke

All these suspended substances make the air unhealthy and put our health to great risk. Therefore, we need an air purifier to reduce these impurities and purify the air that we breathe.

Devices that reduce pollutants such as dust, dirt and pollen grains are known as air purifiers. They can help in reducing second hand tobacco smoke. Your children and other loved ones are often subjected to inhalation of tobacco smoke in your home. If you want to avoid that, use of an air purifier is suggested. You will be pleased with result.

It is easy to see why air purifiers in India are in huge demand. These machines benefit families who own pets. Many quality air purifiers can trap pet hair as well as the stink from their droppings, both of which are great health hazards. People who own business related to pets and healthcare, for example vets, pet shops or even hospitals, should use one. Clean and fresh air also makes you feel energetic.

With the rise of pollution levels in India and increase in number of cases of asthma, sales of air purifiers have reached a new height.

KENT Ozone Air Purifiers produce Ozone Gas, a highly reactive oxidant with the exceptional power to kill Bacteria, Viruses & harmful germs present in air.

A vivid description of RO water purifiers

Reverse Osmosis (RO) is a water purification technology that uses a semi permeable membrane to remove impurities from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property that is driven by chemical potential, a thermodynamic parameter. Reverse osmosis can remove many types of molecules and ions from solutions, including bacteria, and is used in both industrial processes and the production of clean drinking water.

Reverse Osmosis (RO) purification process is essential and effective in reducing harmful dissolved impurities like arsenic, fluorides, heavy metals, etc. During purification, conventional RO water purifiers waste a very high percentage of water (around 80%) while retaining only 20% of purified water. The amount of water wasted was serious concern for Kent, keeping in mind the fact that many people do not have access to water, leave alone clean drinking water.

Keeping all these factors in mind, Kent has developed an innovative and patented technology, which offers no water wastage in RO purifiers. The heart of this technology is a computer-controlled process wherein the membrane is washed automatically and more than 50% of water intake is recovered as purified water. The remaining rejected water is stored in a separate ‘Reject Water Tank’, which can be utilized by consumers for household purposes. The final result is no water wastage. This technology can be found in Kent Supreme water purifier.

This innovative machine is backed up with Kent's patented Mineral RO technology that provides double purification of RO + UV + UF. This technology removes even dissolved impurities such as chemicals and salts. The TDS controller maintains essential natural minerals, thereby providing safe drinking water, which is ideal for consumption. Unlike UV and only RO purifiers, Kent Supreme removes dissolved impurities like chemicals, pesticides, rust, etc. in water while retaining essential natural minerals that are required in drinking water.

Kent Supreme can purify water from different sources such as bore-wells, overhead storage tanks, water tankers and even municipal taps. The technology in Kent Supreme allows the user to adjust the TDS level of purified water and thus breaks the myth that RO purifier can only be used for raw water having TDS level greater than 500 ppm.

The fully automatic operation present in Kent Supreme allows the purifier to begin purification whenever water level in the purified and water storage tank falls below maximum. Level sensors ensure that the purifier is automatically shut off when either of the tanks is full. This ensures trouble free operation without the need of manual intervention.

All these features make Kent Supreme one of the best water purifiers in India.

The Most Effective Method of Obtaining Clean Water

We are living in the age of industrialization and development. Everywhere you look, you can find traces of pollutants and their source as well. The sight of towering chimneys spewing black and contaminant laced smoke is sight that we all are familiar with, isn’t it? All these methods of water purification are capable of removing contaminants from water. However, some advanced water purifiers, like Kent’s Mineral RO prefer using a combination of RO+UV+UF+TDS control to provide clean drinking water.

Apart from spewing smoke into the atmosphere, many of these industries are conclusively interconnected to our water system. Many chemical factories need to discharge waste. This waste often ends up in our rivers or lakes. Laws of the country have not been enough to deter these companies from doing so.

Farming may seem safe, however, we often fail to notice that the fertilizers and pesticides that is used during farming consists of harmful chemicals. These chemicals seep through the ground and contaminate the ground water sources.

The above-mentioned reasons are enough to encourage one to drink purified water. There are two different ways of obtaining clean drinking water. Here’s a look at them.

1) Bottled water: Many people searching an alternative to the contaminated tap water find solace in bottled water. However, studies suggest that bottled water may not be as safe as it is often perceived to be. In fact, the majority of evidence shows that it’s worse for your health than tap water. The issue with plastic is that it leaches toxins into the water it is holding, a fact that has been linked to different types of cancer. It is also noted that many water-bottling companies merely sell tap water in the name of purified mineral water.

2) Water purifiers: The best way to obtain clean drinking water is by installing a water purifier. Water purifiers are devices that use a purification technology to eliminate contaminants in water. These life saving devices can use either of the below mentioned purification technologies.

1) Reverse Osmosis technology (RO)
2) Ultra Violet technology (UV)
3) Gravity based UF technology

All these methods of water purification are capable of removing contaminants from water. However, some advanced water purifiers, like Kent’s Mineral RO prefer using a combination of RO+UV+UF+TDS control to provide clean drinking water. This unique combination also ensures that minerals that essential to our body are not lost.

Kent RO Systems Limited is a 21st century healthcare products company with a vision to make the world a healthy and a happy place. Pioneers in bringing the revolutionary Reverse Osmosis (RO) technology to India, KENT started its operations from Noida, India in 1999.

Today, the group is recognized worldwide as a company that produces some of the best water purifiers in India. 

Understanding TDS in water

Those days are long gone when water could be consumed directly without a second thought. The situation has completely changed now. The lakes, ponds, rivers, dams etc. are often polluted with factory and domestic waste and hence, it has become highly essential to purify water before consuming it. Apart from this, excessive usage of pesticides in agricultural fields for enhanced crop yields has also increased the pollution level in ground water.

The tap water that you receive from the municipal corporation often remains contaminated. This is due to the fact that they use outdated and inefficient methods of water purification. During its journey to your home, water often comes in contact with rusted and burst pipelines. This also leads high level of TDS in water.

What is TDS in water? Total dissolved solids (TDS) comprises of inorganic salts (principally calcium, magnesium, potassium, sodium, bicarbonates, chlorides, and sulfates) and some small amounts of organic matter that are dissolved in water.

Effects of TDS are as follows -

1) The concentration of TDS may cause the water to be corrosive, salty or brackish taste, result in scale formation, and interfere and decrease efficiency of hot water heaters.

2) Many contain elevated levels of ions that are above the norms, such as an elevated level of nitrate, arsenic, aluminum, copper, lead, etc.


TDS in drinking water originate from natural sources, sewage, industrial waste water, and chemicals used in the water treatment process. The astounding rise in water pollution has led to the rise of water purification methods.

Boiling is water is one of the oldest water purification and is considered to be safe. Boiling water successfully eliminates pathogens but remains ineffective against suspended impurities and chemicals.

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:

Water Softeners - A brief look

What is hard water?

Hard water is basically a high concentration of minerals in the water, most commonly dissolved compounds of calcium and magnesium, either as carbonates or sulphates. Water hardness is measured by how many parts per million (ppm) of the minerals are dissolved in the water.

What are the causes of hard water?

Hard water can be either temporary or permanent.

Temporary hardness in water is often caused by the presence of dissolved carbonate minerals (calcium carbonate and magnesium carbonate). Boiling hard water precipitates the calcium carbonate out of solution, leaving water that is softer when it cools. However, suspended particle remain unaffected even after boiling.

Permanent hardness is usually caused by the presence of calcium and magnesium sulphates in the water. These salts become more soluble as the temperature increases, and cannot be eliminated by boiling. Despite the name, permanent hardness can be removed.

Both kinds of hardness, temporary and permanent, can be removed by installing a water softener, which filters out most of the minerals suspended in the water.

What are the effects of hard water?

Below mentioned are some effects of hard water.

On Clothes:

Hard water prevents formation of adequate lather, which leads to higher soap consumption. What's more, clothes become stiff, rough and remain dirty even after washing.

While Bathing:

Bathing with hard water makes hair sticky and leads to hair loss as well. Also the skin feels dry and itchy after bathing.

On Dishes:

Using hard water while cleaning, leads to the formation of chalky white spots on utensils and cutlery. This further reduces their life span.

Hard water can also clog your pipes and prevent your washing machine from operating at full efficiency.

In commercial applications, hard water can present a real problem. Hard water deposits (off-white scales) can clog pipes. It can be deposited on the surfaces of pipes and heat exchangers, restricting the flow of water, and compromising the efficiency of the heat exchanger. In some cases, it even causes corrosion. Mineral deposits can also cause metal boiler components to
overheat, and can cause the boiler to fail.

Installing and maintaining a water softener, as part of industrial water treatment strategies will usually alleviate the problem.

Kent Mini Water Softener is the world's first compact water softener that converts hard water into soft water in an easy and convenient manner. It can be easily fitted to your washing machine, geyser and dishwasher. Kent is known as ‘House of Purity’ due to its immense contribution in the field of water purification.

How to purify water without eliminating the minerals?

How important are the minerals present in water? Minerals present in the water like sodium, calcium, magnesium and iron are very important for the general health of our body. Drinking natural mineral water is the best way to ensure daily intake of these minerals.

Below mentioned are some minerals that are important for our bodies,

1) Calcium:  It is required to maintain and increase the strength of bones, teeth and cartilage.
2) Magnesium: It helps maintain muscular and nervous equilibrium.
3) Iron: This mineral is important in building up hemoglobin, the oxygen carrier in our blood.
4) Iodine: It helps regulate the growth of thyroid gland.

Water filled with minerals is recommended for skin and hair too. The minerals present in water enhance the health of skin and hair – not only from outside but from inside too. Moisturizing the skin from clean and pure mineral water keeps the skin moist, soft and healthy.

Minerals are naturally present in water. However, with the increase in pollution, it has become impossible to consume water directly. Water purifiers are often used to purify water and make it worth consuming. However, water purifiers eliminate not only pollutants but also minerals. Water purifiers that use Reverse Osmosis are known to filter out minerals along with contaminants.

Drinking water that does not contain minerals only helps us quench our thirst but does not meet our body’s minerals requirement. Consuming such water is not recommended as it eventually leads to mineral deficiencies.

Kent has come up with a unique water purifier that has the answer to this problem. Kent’s Mineral RO water purifier uses a combination of RO+UV+UF+TDS control to purify water. This technology ensures that the water becomes not only the purest, but is healthy too.

One Distinct advantage which sets KENT RO purifiers apart from other RO purifiers is its ability to retain essential minerals in water. This unique water purifier removes suspended as well as dissolved impurities. As visionaries of the future and health living, KENT provides a bridge between scarcity of purity and its availability.

Kent also has a number of other purification devices in its production. Air purifiers, Vegetable and fruit water purifiers, Tap guards are some of the other purification devices that Kent has in its production.
