The whirlpool destroyer is not just a purifier; it’s a smart purifier. With so many technologies available in the market today, whirlpool destroyer is the smartest technology for you. Let’s understand how whirlpool destroyer is smarter than the rest of the technologies. In gravity technology, the water passes through chlorine and other filters to remove microbial contamination.
Did you know it can remove microbial contamination but has limited effectiveness in removing chemical impurities?
Five reasons why the whirlpool destroyer is smarter than RO
If the TDS level of water at your home is less than 500 ppm, then the whirlpool Destroyer is the perfect choice for you. It’s revolutionary EAT technology gives you natural tasting drinking water, so stay healthy with the old new whirlpool destroyer and drink only pure water. Providing healthy drinking water is one of our key businesses’ whirlpool designed to delight.
Do you know about the source of our drinking water? Let me tell you that 75% of our earth’s surface is covered with the water; however, only 1% of that water is drinkable water and that potable water is stored in rivers, ponds, lakes, Glaciers, Borewell, and groundwater. So the water we drink every day comes from any one of the sources mentioned above.
We need to know about the source of drinking water that we drink every day that will help you figure out what type of water purifier you need to buy. The money you will spend on your new water purifier is not an expense; instead, it is an investment to save you from waterborne diseases. According to WHO, 90% of the deceased are penetrated from waterborne diseases. That is why I suggest you buy a water purifier according to your requirements, which will save you from polluted water and keep you healthy, always thereby reducing your medical cost.
The first and foremost criterion to select the best water purifier India is to know the TDS (Total Dissolved Solids) level of water supplied to your area. The TDS (Total Dissolved Solids) Level is the unit of organic and inorganic salts present in the water. TDS is measure Unit is PPM (parts per million) or mg/liter. The more the TDS level of water, the more are the solid dissolved in it.
People usually believe that more TDS level means contaminated water and less TDS level means better water which is not valid as Dissolved solids contain harmful solids like Arsenic, lead, and chlorine. Still, it also contains beneficial minerals like Calcium, magnesium, Sodium, Potassium, and phosphorus. So less TDS level also means less beneficial minerals that say 10 % beneficial minerals are also removed with 90% impurities.
Usually, Packaged water comes with a TDS of less than the 50 PPS, which means it is pure water; however, it does not contain beneficial minerals. Packaged water is not suitable for the long term as it can lead to weak bones, fatigue, and other health diseases. On the other hand, brands like Himalayan and Evian provide packaged water with TDS of 300, which doesn’t mean the water is not good as it contains the beneficial minerals required by our body. That is why these brands are costly. All I mean to say is that never judging the water with its TDS levels rather judges it through the proportion of beneficial minerals and impurities in it.
Organic Salt typically includes Minerals like Calcium, magnesium, Sulphate, Chlorine, and many more, and it also contains harmful metals like Lead, Zinc, Arsenic, etc. So the TDS is the level of minerals found in your water.
For example, your Water TDS is 200; It means that 1 Liter of water contains 200 milligrams of dissolved salts.
UF (Ultra Filtration) water Purifiers contain an Ulta filter chamber contains a large number of hollow white fibers that are made of Polymers.
These hollow fibers are semipermeable membrane that has a pore size of 0.001 Microns. The fibers let water pass through it; however, it prevents impurities like Silt, Toxins, bacteria, and other harmful viruses to pass through it.
The UF water purifiers also contain Active Carbon filters highly porous and have a high absorption capacity. The active carbon can quickly absorb impurities like chlorine, and it also removes odor from the water. The Ultra Filtration water purifiers are very low cost as they don’t require electricity, and it works on gravity, which is why there are also called gravity-based water purifiers. The UF water purifiers are suitable for the people whose water TDS levels are 200 and below.
The Advantages of UF (Ultra Filtration) Water Purifiers
The Disadvantage of UF (Ultra Filtration) Water Purifiers
There are 3 -4 techniques used in the electric water purifiers, and two methods, namely RO(Reverse Osmosis) and UV(Ultra Violet) are used either separately or in a combination of RO+UV and RO+UF+UV.
In UV purifiers, Ultra Violet Filters are installed. The ultraviolet cartridge contains the 11 Watt tube in the middle section, which emits the ultraviolet rays with less wavelength than visible light. It can also damage our eyes. These ultraviolet rays activate when the water is transmitted through the ultraviolet filters. These invisible rays eliminate all the bacteria, pathogens, and other harmful viruses that try to pass through the screen along with water. The Ultraviolet rays have the capacity the damage the DNA of the bacteria and to eliminate its reproductive capacity.
The UV filtration is the last stage in the RO systems, so it eliminates only those bacteria and germs which could not be removed by the RO and UF filters. The UV water purifier is suitable for the water, which has the TDS levels of 200-500. UV lamps throw UVC rays of 254 nm.
The Advantages of UV (Ultra Violet) Water Purifiers
The Disadvantages of UV (Ultra Violet) Water Purifiers
Almost every one of us might have heard about the RO purification systems, as these are the most commonly used water purifiers in 2020. The RO systems were made to eliminate the drawbacks of UV and UF systems.
RO water Purifiers also contain the membrane, just like UF water purifiers. However, it has a reverse osmosis membrane, which passes the water with high pressure and has pores smaller than the UF filters of 0.0001 Microns. The benefits of small pores are that it eliminates all the heavy metals and salts from the water.
Advantages of RO (Reverse Osmosis) Water Purifiers
Disadvantages of RO (Reverse Osmosis) Water Purifiers
With modern technology, many companies offer RO purification systems with TDS controllers called TDS adjuster, a taste enhancer, Manual TDS by different brands. You can control the TDS output of water manually through your water purifier.
Now let us understand how a TDS controller works? So when the water enters the purifier, it goes through various filters like a pre-sediment filter, carbon block filter and many more and finally when it reaches the RO filter, the water gets diverted into different streams with the help of TDS controller where one stream goes into the RO filter and other go through the UF/UV filter. The final output you will get is the combination of both RO filter water and another filter.
Let us say your water TDS level is 500, and you have diverted 80% of the water through the RO filter, and the rest 20% is passed through the other filter. Now, the RO filter will reduce the TDS level up to 90%, and TDS of 80 % water will be 50 approximately and rest 20% of the water will have the same TDS level of 100. So the final output TDS of the water you will get will be approx 150.
If you had passed the complete 100% water through the RO system, the TDS level would be around 70, which is less than 150 TDS. You can also increase the TDS level by adjusting the water ratio with the TDS controller’s help. For example, you can pass 70% water through RO filter and rest through the other filter to enhance the TDS levels.
Now, if you have understood the working of the TDS controller, let’s talk about the suitability of the TDS Controller and who should buy a TDS controller if you live in a highly polluted city like Delhi, Kanpur, Agra, Pali, Ratlam, etc. or where there are heavy industries are located that throw out the chemical waste through water or smoke. Such cities have a high chance of heavy metals and pollutants in water.
So if you live in such cities and your water TDS level is 300 or more, than you don’t need a TDS controlled Water purifier. If you live in a clean city and your water TDS level is 400-500, you don’t require a RO water purifier. However, if water taste in your area is slightly bitter, you can buy a RO water purifier and adjust your TDS level between 200-300.
Now I will discuss the components process flow diagram, electrical circuit, general electrical problems, and maintenance tips for your UF/UV purifiers. Let me remind you that UF stands for Ultrafiltration, and UV stands for Ultraviolet Radiation ranging from 190 nanometers to 400-nanometer wavelength in this case.
First, let me come to the parts of a standard UF/UV purifier where we can separate parts into two groups. One group is related to the filtration, and the other is related to the operation.
Filteration process: filtration process of UF/UV purifier includes components, namely inline sediment filter (5 microns), inline activated carbon block filter, UF Membrane Cartridge, and UV Disinfection Cartridge.
Electrical Operation: The components, namely Adapter, Float switch, Solenoid Valve Ultraviolet Lamp, and Storage Tanks, are involved in the electrical operation and storage.
Let me discuss the design and operation of the solenoid wall in a purifier. The Solenoid Valve is an electromechanical device that consists of extended spring magnetic core, solenoid rubber valve, and a chamber. In a water purifier, usually closed two-way 24 volts DC operated solenoid valve is used to prevent the tank overflow due to the inlet water pressure normally closed solenoid wall remains closed till it gets power and water cannot flow but once it gets power water flows in the purifier. Generally, solenoid Valve is provided after the inline sediment filter the role of Paulino at Valve in any electrically operated water filter is to stop the flow of water as soon as that storage tank reaches to its highest level or it gets filled floats which cut or stop the 230 volt AC mains supply of the whole purifier as soon as the storage tank filled. Still, it does not stop the physical flow of water due to the inlet pressure; the solenoid valve prevents the physical flow of water.
Fluid switch is an electromechanical device consisting of a spring and airbag and a switch. When the storage tank fills the airbag of the device, it exerts pressure against the spring of switch and cuts the main supply. As soon as the main cut solenoid was closed, the water flow and ultraviolet lamps turned off no power consumed by the purifier once the tank was filled, which is an ideal situation.
Typically, a water recycling plant uses reverse osmosis to treat wastewater after the ultrafiltration process further. Reverse Osmosis membranes are constructed from a membrane flat sheet. It comprises three layers a PolyesterFabric Support Base, a Microporous
Poly Cell Phone Layer, and a 0.2-micron Thick Polyamide Barrier Layer. The poly cellphone layer strengthens the very thin barrier layer. It is the barrier layer that removes nutrients, chemicals, bacteria, and viruses from the water. The flat membrane sheet is combined with a sheet of feed channel spacer, which provides turbulence and creates space between the membrane sheets for the feed water. A sheet of permeate spacer is added to the membrane sheets and feed channel spacer, which enables the final recycled water product or permeates to flow evenly across the entire membrane surface even under high pressure.
The back of the membrane is completely sealed to the edges of the permeate spacer the membrane sheets are glued along each of the three exposed sides and rolled around the core tube. Feedwater is forced through the feed channel spacer and into the barrier layer of the membrane water passes through the membrane surface into the permeate channel.
It flows in a spiral direction and collects in the core tube, and this water is the final recycled water product or permeate. There are seven spiral wound elements loaded in one pressure vessel once the end adapter is connected to the last element, and the pressure vessel is sealed feed water can be introduced. Feedwater is pumped at high pressure into the vessel as it travels small molecules like water pass through the membrane while larger particles such as salt bacteria and viruses do not. The final recycled water product is collected from the end of the elements, and the concentrate or reject from that vessel flows to another stage producing more recycled water.
In this animation process flow of a typical UF/UV purifier is explained.
Water, the most flawless everything being equal and unadulterated drinking water, ought to be liberated from physical-synthetic and natural tainting. It ought not to have a terrible taste or awful smell; not simply this, it ought to have basic minerals that are required for sound living. As per the WHO, the TDS level in drinking water ought to be under 500 ppm. Whirlpool comprehends this better than any other person; thusly, they have introduced the all-new Whirlpool destroyer that ensures clean drinking water with its progressive EAT (Electro Adsorption Technology) that accompanies a propelled 5 phase refinement.
let’s understand how the 5 stage filtration works
Earth is a watery planet, yet water is a precious commodity. Can you guess why? It is because just 3% of all the water available on earth is freshwater. The rest 97% is saline water of the oceans. Out of this 3%, the surface water of rivers leaks or Springs forms an even smaller percentage of freshwater from various sources. It may contain disease-causing germs and impurities. Large-scale water purification is done before it reaches our homes. So let’s see the journey of water before it gets our home. At the end of this module, you will be able to define and describe sedimentation filtration and aeration describe the process of chlorination and adding disinfectants describes the journey of water from the sources to our homes. A simplified diagram of a water treatment plant freshwater from the rivers and lakes is taken through pipes to large water treatment plants for purification.
In the first stage of purification, water is pumped and stored in large sedimentation tanks. Alum is commonly used as a coagulant that forces tiny particles of dirt to stick together and settle down. In the second stage, water is carried from sedimentation tanks to the filtration tanks where water is passed through charcoal sand and gravel beds. This process removes the remaining suspended impurities.
The third stage of the purification process is that aeration air is passed through the filtered water in the reservoir by a pump with air diffusers. The circulation of air reduces the concentration of taste and odor-causing substances. This process is known as aeration disinfecting is the first stage of the purification process. In this stage, water is carried from the aeration tank to the disinfectant tank adding disinfectants such as chlorine destroys disease-causing organisms in water ultraviolet radiation and oxidative chemicals such as potassium permanganate and ozone are also used for disinfecting water.
Next, the water is purified and ready to drink this water is stored in the storage tanks and supplied in towns through underground pipes. Thus, water undergoes several processes before reaching our tabs as potable water to make our tap water extra safe for drinking.
We can follow some straightforward methods in our kitchen. A simple filter directly fitted to the kitchen tap boiling the process of killing harmful germs by boiling is called sterilization of water. Boiling the water for one more minute after it reaches a rolling boil makes it safe for drinking. Remember if you need to use bottled water to check for these Bureau of Indian Standards BIS mark. The seal is intact, and there is no leakage from the bottle the manufacturing date and best-before date crush or puncture the bottle after every use to ensure that the same bottle is not used to refill water again.
Today we’re going to contrast Reverse Osmosis with ultrafiltration. We’re going to discuss how they determine and have preferences more than each other and where they have disservices. Reverse Osmosis and ultrafiltration generally alluded to as RO and UF, is film innovation. The reverse osmosis framework utilizes a semipermeable film, and it’s isolating inorganic broken up inorganics from the water particle. The UF framework uses an empty fiber film, and it is essentially a mechanical channel, and it’s halting massive trash or particulate, yet down at a microscopic level. It’s beautiful at .025 micron. That is the reason it’s called ultrafiltration. Yet, it is only a channel. It is anything but a reverse osmosis measure where we’re isolating atoms. Reverse Osmosis kills most of the disintegrated minerals. Many individuals like that since they need their drinking water as unadulterated and free as conceivable from mineral, synthetic compounds, or what they have. So the RO framework has the bit of leeway on that. Ultrafiltration won’t dispense with broken down solids. It’s just going to manage solids. Presently for people that like mineral left in the water, the advantage is ultrafiltration. Reverse Osmosis is a cross-stream filtration. We make two ways, or two water streams, through the layer.
One way winds up in our capacity tank. A capacity tank could be an inconvenience. Since it makes water so gradually, we need to store it to make it accessible. That occupies space under the counter. It likewise needs to attach to the channel, because the water conveying those broke down inorganics away is setting off to the track. That could be a weakness from a water preservation stance. Ultrafiltration additionally doesn’t need a capacity tank. It truly connects straightforwardly to the extraordinary spigot.
Furthermore, coincidentally, both of these frameworks do require a committed spout. It won’t go through your standard installation on your sink. Yet, the ultrafiltration framework it runs straight through to the fixture. No requirement for a capacity tank. It gets through the channel at a gallon for every moment. Favorable position ultrafiltration. A reverse osmosis framework will be somewhat more intricate to introduce. You have a couple of more associations with make. Water experiences an air hole fixture for reverse avoidance. It attaches to the channel line.
It connects to the capacity tank, so there’s greater unpredictability to introduce a reverse osmosis framework. An ultrafiltration unit is fundamental. You associate this feed flexibly, and the opposite finish of the channel you interface legitimately to the devoted spigot. Exceptionally simple to introduce. Reverse Osmosis, the underlying expense will be somewhat higher than the ultrafiltration framework. You have more parts. It’s merely going to work out to be slightly more cash. The ultrafiltration framework is slightly less.
What’s more, we’re going to discuss ongoing cost, the substitution of channels and layers; the ultrafiltration framework will be somewhat more when you average out the expense of supplanting the channels and the empty fiber film, which you will substitute slightly more as often as possible than the reverse osmosis layer. It will adjust to being somewhat more than the channel cost on keeping up the reverse osmosis framework. That summarizes the examination among RO and UF.
In this age and era where water-borne diseases are increasing to the consumption of contaminated water, it has become imperative that we protect our families by ensuring that pure drinking water is available. It is not enough that just water looks clean. It has to be free of disease-causing bacteria and pollutants and all traces of heavy metal as indicates the novel water rampantly being used to bridge the dismal gap between the small availability of sweet water and ever-increasing demands. Every year India alone accounts for over 36.6 million water-borne disease cases, but now we can take affirmative steps to protect our family.
It is our duty to understand the environment around us and find the Best Water Purifier in India 2021. I hope you liked this post please give your opinion in comments.

The ideal pH level for drinking water is 7. The water purifier that can give you pure drinking water without eliminating the essential TDS levels and healthy minerals is AO smith green series.
The significant drawback of RO water is that it also clears out healthy minerals and harmful hard metals during the purification, which in turn reduces the nutritional value of drinking water, which is not suitable for health in long terms. Therefore always opt for a purifier with RO+Mineralizer+TDS controller.
It depends on the TDS levels of water in your area. If your TDS level is between 200 and 500, then UV is suitable for you because the UV purifier can quickly remove impurities in water under 500 TDS. If your water TDS level is between 500 – 2000, then you will need a RO water purifier because only RO purification can remove stubborn and harmful impurities on such level. However, RO purifiers have a tendency to remove healthy minerals like magnesium and copper, which is not suitable for long period consumption.
Both RO water and boiled water have disadvantages as if you live in an industrial area or the area where water is contaminated with chemicals, waste, metals, and radioactive waste, then the RO water purifier is mandatory because it is designed to eliminated such harmful chemicals and hard metals. On the other hand, if you live in a clean area, you can drink boiled water as it can remove the bacteria while containing the essential minerals, unlike RO water.
There is no such level of ideal TDS because less TDS level of 150 can have more hard metals like arsenic, cadmium, chromium, copper, nickel, lead, and mercury, and water with a high TDS level of 1000 can have more healthy minerals like calcium, magnesium, potassium, sodium, bicarbonate, iron, zinc. The right way to check the ideal drinking water is through a formula. The unit of measure of TDS is PPM (parts per million) or mg/liter. You should check the Minerals’ ratio to hard metals in the water to check the ideal drinking water level.
Step 1: Check the TDS level of water in areas you live in.
Step 2: Choose the type of water purifier with features according to your TDS levels.
Step 3: select some water purifiers within your Budget
Step4: compare their features, brand value, build quality, after-sales service, maintenance cost, and choose the best water purifier in India.
Any water pH level below 6.5 means that water is acidic in nature. It is also called acidic water. Any water pH level above 8.5 means hard water filled with Bactria, which is also not drinkable water. It is also called Alkaline water. That means any pH level between 6.5 to 8.5 in your area indicates pure water. Check Best water purifier in India.
