Choosing The Right Water Purifier – Following An Easy Water Purifier Buying Guide

Choosing the right water purifier can be difficult. Read this water purifier buying guide to know more.

Why Do We Need A Water Purifier Buying Guide?

The water that is supplied to your house comes through various water resources. These sources of water are likely to contain various kinds of impurities such as TDS and suspended particles. Hence, the purification of drinking water is of the utmost priority. The water, before it reaches your house, is given chlorine treatment by the municipalities. But this doesn’t make it completely safe for drinking.

A water purifier will take care of the aforementioned problems. You need technologies like Reverse osmosis, ultraviolet, and ultrafiltration to keep out the contaminants. The water purifiers out there, with these technologies, in the market, are capable of eliminating such impurities. Hence, a water purifier buying guide will help to understand which one is beneficial for you. 

How To Choose Water Purifier?

There are so many questions that crop up in one’s mind when we talk about water purifiers. The usual questions are how to choose a good water purifier and what is a good water purifier. To answer both these questions, we need an accurate understanding of water purifiers. And only a guide to buying water purifiers can help us. A water purifier buying guide is not a manifesto. Neither is it a manual of some sort. It just includes the important points you need to keep in mind when you buy a water purifier. However, the question of how to select a water purifier is a primary one. 

What Should You Keep In Mind?

It is not difficult to choose a good water purifier. However, there are three important things that you have to keep in mind. Firstly you need to know the amount of water consumed by your family members. It is because these days, various water purifiers have certain storage capacity. Therefore depending on the quantity of water consumed at a given point of time, you can determine the water purifier best suited for you. Secondly, you have to see the pressure and flow of water in your area—the more the pressure, the quicker the filtration process by a purifier. Thirdly you need to know the quality of tap water in your area. Unless and until you are entirely sure about this, you cannot buy a water purifier. If you buy one without knowing one or all three of these, then that water purifier you pick to buy may not serve the best purpose you and your family deserve. There are many localities where the tap water quality is not good. There are many areas where the tap water contains a high quantity of iron. There are even areas where the water contains arsenic in trace amounts. 

Here are some handy tips to remember before buying a water purifier.

History Of Water Purifiers

Water purifiers went through massive structural as well as functional changes. Previously there were different types of water purifiers in India, which had a metal body and metal wiring inside. These machines were heavy. The machines had a life of ten years and more in some cases. However, these machines had a fault too. Since the body and the networks were metallic, they mostly consisted of iron. Now we all know what happens when iron comes in contact with water. The inside of these machines would eventually catch rust, and they became useless after a point of time. But, everything changes with time. It is exactly the same in the case of water purifiers. Plastic replaced the metallic structures while silicon took up the network systems. Altogether, water purifiers nowadays are more viable and convenient than they were before.

Types Of Water Purifiers

The plastic body and the silicon pipes made reduced the chances of rust. Since plastic and silicon are both lightweights in nature compared to iron and burnt clay, it is easy to carry these water purifiers from one place to another. You might wonder, why is it necessary to shift a water purifier from one place and relocate it to another? Well, not every one of us has a permanent home. Some of us change our rented apartments from time to time. A good water purifier is challenging to carry and replace in that case. In the case of modern purifiers, you can transfer them anywhere you like without making any extra effort. Moreover, maintaining an iron made water purifier was not easy. All the parts underwent reliable welding, and you could not detach them. If there was anything wrong with the purifier, you had to replace it.

Membrane Filters

Membrane filters are the purest forms of filters available in the market today. You can attach these to the tap directly and get filtered water straightaway. These membranes or contraptions have a mesh of wire that traps the sediments and prevents the mixing of any insoluble particles. The wire meshes contribute to the filtering of the water.

The primary areas in which you will find the usage of these filters is in the hilly region. Since these mountainous areas are near a river source, the pure water that you get from the rivers directly often have particles such as sediments in them. These organic impurities present in water are harmful to intake or usage in any other form. The membrane filters will not only purify the water but also filter it out and make it suitable for drinking purposes.

Gravity Based Water Purifiers

The gravity-based water purifiers are the most efficient and convenient forms of filtering in today’s generation. They are abundantly available in the market too. These purifiers comprise a carbon filter that purifies the water with a lower level of TDS. These water filters are an upgrade from the standard faucet based water filters. Moreover, they have a storage capacity similar to that of a tank and can store enough water for an entire family.

The gravity-based water purifiers or water filters have two separate tanks. One is the input tank, while the other is the output tank. The best areas in which you can install these tanks are the ones where the level of TDS in water is high.

RO+UV+UF Water Purifiers

There are different types of water purifier in India. In the case of places where the water has iron or arsenic in it, you need to buy a water purifier that comes with RO and UV and TDS controllers. The TDS controller ensures that your water is free of any micro-organisms and/or foreign substances that might affect your health. These existing foreign substances include living organisms and germs that might affect your digestive system. RO is reverse osmosis that filters the water in different ways to get rid of impurities like arsenic and iron. UV is ultraviolet rays that ensure complete protection to the filtered water. This kind of water purifier is usually expensive. Moreover, this kind of water filter requires proper and periodic servicing.

These filters remove impurity from water through reverse osmosis. It removes mercury, iron, arsenic, lead, and more of such harmful metal oxides from water. Thes water purifiers and filters can also discard viruses and bacterias. One can get rid of microorganisms, too, using these RO water purifiers. The UV filters come with UV and UF membranes and compartments. Know everything about RO Vs UV Vs UF and see which One Is The Best.

EAT Filters

The EAT filters also are known as Electro Adsorption Technology. It is the latest technology introduced in water purification. These filters are somewhat similar to that of a UV filter.

How To Choose The Perfect Water Purifier For Your Home?

Before jumping on to buy a water purifier, several factors are to be considered. And it is highly essential to attach a water purifier in your home in order to avoid falling sick.

· Determine the TDS value of the water. Based on the TDS value, you have to choose your water purifier.

· In case you live near an industry, make sure to find out if the water coming into your house has chemical impurities.

· If you’re unsure about which filter to use, go for the RO+UV filter.

Which Water Purifier Should I Choose?

Nowadays, there are several options to choose from while buying a water purifier as specified above. However, RO technology seems to have become synonymous with water purifiers. As a result of this, when we talk about water purifiers, most people simply go ahead and purchase a RO water purifier without considering certain scientific assumptions. When you are unable to decide which water purifier to buy, you must take into consideration the TDS level of input and output water. RO purification is usually required when the TDS value of water is high. In every RO buying guide, knowing the TDS value of water is the primary point. The TDS value is usually considered high when it is around 500 ppm. 

In recent times, there are several different types of water purifiers available. Starting from tap filters to faucet filters, gravity purifiers to RO purifiers, and many such more. The increased range of water purifiers simply made it more difficult for people to purchase one for their home or office. The complexity of buying a water purifier is increasing day by day.

How To Select Water Purifier? 

If you ask an expert on how to select a water purifier, he or she will tell you to buy one based on the TDS level. According to research, the maximum safe limit of drinking water is around 500 ppm. If your water has a TDS value that is much less than the benchmark value, then you do not need to purchase a RO purifier. A water purifier buying guide mentions that water having a low TDS value will simply be reduced further if an RO purifier is used. If this happens then, the drinking water will not have minerals such as calcium, magnesium. These minerals are good for your health, and your water must contain these. Water, which has a TDS level of less than 500 ppm, is prone to bacteria and viruses. 

Best Water Purifier In Budget

Compared to iron made water filters, plastic- body water purifiers are more cost-effective. The usual setup inside these water purifiers consists of four main things. There is a direct current motor for conducting electricity. There are channel pipes for entry and exit of water. There are network pipes to ensure the smooth flow of water. And there are structures to hold the pipes made of good quality silicon. These filters usually contain high-quality plastic. They have three-layered protection along with that.

Water Purifiers In Offices

Types of water purifiers also differ in terms of home and office use. Households are not the only place where water purifiers find themselves. They are installed in offices too. Water purifiers that get installed in offices are usually of higher capacity. They have filters that can filter large quantities of water quickly. Moreover, the standard of equipment is better compared to basic household purifiers. They do not consume high units of electricity. However, these purifiers require round the clock maintenance. Without robust maintenance, a water purifier in a commercial establishment can fail its consumers to a great extent. You should also keep in mind that water purifiers in offices cater to a large group of individuals. 

How To Choose A Water Purifier For Your Home Or Office? 

Although different water purifiers have different technological flaunting, the basic purification approaches of every water purifier are a mixture of RO, UV, and UF. 

To know the processing and functioning of each step go through the following points: 

  • UF or ultrafiltration works best for water having a low TDS level. This is usually the case for soft water. 
  • Hard water has a higher TDS value; hence, RO water purifiers are used. Often hard water has a high level of contamination. In such cases, one should opt for water purifiers that have RO, UV, and UF together. 
  • UF filters work best with any other form of the water purification system. They do not kill any biological microorganisms but remove the suspended particles from water.

RO buying guide

Before going for your RO buying guide, it is essential to know what are the components present in an RO water purifier. 

The main parts of the RO water purifier are a sediment pre-filter, activated carbon pre-filter, RO membranes, UF membranes, TDS controller, UV filter, Carbon Post filter, and a storage tank. Due to the piling up of such massive and bulky components, the RO based water purifiers have some considerable weight. Before mounting it up in your kitchen or office cafeteria, make sure to get the exact dimensions and match them up that of your walls. A misplaced purifier can result in the water flow not being accurate. 

Now let’s get into the details of what every component has to contribute in the purification process—the sediment pre-filter purifies the water at the very first stage. The screen removes the dirt but maintains the quality of the RO and UF membranes. One can add the sediment filter separately, too, if it does not come with the water purifier set. The next component is the activated carbon filter. This filter removes chlorine and organic impurities from the water. 

Next comes the RO and UF membranes. The RO and UF membranes perform the same function. Moreover, RO removes heavy metals like lead and arsenic, microbes like bacteria and viruses ad cysts too. On the other hand, the UF membrane removes all of the same components except the dissolved salts. A good water purifier will have both the RO and UF membranes. These membranes maintain the TDS level of water to make the drinking water purifier and healthy to consume. 

The most critical component of any filter is the TDS controller. The TDS controller keeps the essential mineral quantities intact by adjusting the levels of water from the RO and UF. It is in this step that the harmful impurities are eliminated. Another filter present in the water purifiers is the UV filter. This stage removes the virus, bacteria, protozoa, cysts, and more of such toxic materials. The level of TDS, purification, indicators, tank capacity are all visible in the display section of the water purifiers. 

Why Is Servicing Important?

In places where the tap water is of moderate quality, you can use water purifiers that have only RO and UV. You do not need a TDS controller for such areas. However, without periodic servicing, any good water purifier can start malfunctioning. If your water purifiers begin to malfunction, it can be a dangerous situation. It can cause the germs to remain with the filtered water. Moreover, you might need to replace it before the warranty period in that case. As far as servicing goes, the water purifier company provides you with the service person. You need to make a contract with them. There are usually three types of contracts-quarterly, half-yearly, and yearly. You decide the contract period as per your wish.

Where Do You Need Water Purifiers?

The places which have high-quality municipal water also need water purifiers. Even if the water is of good quality, it gets affected in a lot of ways when during transportation. These places include the municipal reservoirs, the transport pipes, the municipal discharge pipes, and the pipes of your household. These networks do not undergo treatment properly. They seldom get cleaned and disinfected. Thus, a good water purifier is necessary, too, for places having good quality tap water.

However, such water purifiers can be very basic and need not have extraordinary features. Water purifiers that have good quality filters are best suited for such places.

Why Do You Need A Cover?

Water purifiers require protection from the inside as well as the outside. They get generally installed in the kitchen where they get affected by the smoke which comes out of the stove. The outer portion of the water purifier might lose its shine with gradual exposure to the kitchen fumes. Now, these kitchen fumes usually have a very high temperature.

The continuous exposure can damage the exterior in that case to a great extent. The damage to the surface is hazardous. High-temperature fumes might cause the material on the outside to melt. While in that case, there might not be pores that are visible to us; it can still get inside. Once foreign substances gain entry into the purifier, the whole purpose of it is defeated. 

How To Choose The Right Cover?

To prevent any incident as such, you need to cover the water purifiers adequately. You can get these in the market. You need to choose the sheet according to the size of the water purifier. These covers contain high-quality polymer. There are covers available in the market which contain low-quality polymer or plastic. Those covers are generally not durable. They get worn out after a point of time. You need to change them after a short period of time. The covers which contain excellent quality plastic are strong and durable. They have a lifeline of about more than three years. Choosing the right water purifier is not the only thing that you have to do. You need to choose the right purifier cover too. 

Why Is A Water Purifier A Necessity?

A good water purifier was once a luxury for many of us. In the case of office establishments, only the rich ones could afford it. But nowadays, water purifiers are anything but items of luxury. The standard of our lifestyles often reflects the nature of our purchases. If a household wishes not to buy a water purifier in today’s time, that is their choice. But it is not a wise choice. The quality of municipal water in most parts of the world is imperfect. There isn’t a sufficient amount of treatment plants available to get them appropriately filtered. This purchases a water purifier extremely necessary these days.

What Are Water Purifiers For?

Both households and office establishments need a water purifier. The quality of water in the area in which they are does not matter. We all need to ensure proper health and hygiene inside our homes and offices. That requires the installation of appropriate appliances that aid us in our living. A water purifier is nothing less than a helping hand. Moreover, they ensure that both the households and the offices function smoothly. They do this by providing the safest possible water for consumption. Poor quality drinking water can create massive havoc both at home and at work.

Why Do You Need A Water Purifier In Your House?

Poor quality drinking water can make people sick. People who have a fragile immune system can fall quickly ill. The group of individuals who have vulnerable immune systems mainly consists of kids and old-age individuals.

What Happens When You Don’t Have A Water Purifier?

If your child suddenly falls sick in such a manner, your daily routine gets devastated. 

Since his/her health and well- being is your primary concern, you get more than worried. Even if you leave your child at home and come to work, it becomes impossible to put your mind to it. In case you decide not to go to work, then your career suffers because of your indecision. The same thing can happen in the case of the aged and the elderly. In their case, they have two different problems. One is that they do not have a healthy immune system like children. And two, they cannot be treated with strong medicines because of their age. 


 A good water purifier has a system that allows them to reuse the water that is otherwise considered to be waste. The wastewater can be reused, and even the generation of wastewater can be reduced. 

If your water has a TDS level of 150 or less, then the waste generated is much more. A low TDS level of water is not only harmful to your health but also brings about several diseases. You can fix or increase the TDS value of water using a knob. Increasing the TDS value will not only reduce waste but also make the drinking water suitable. According to data from various sources and labs, any average RO water purifier produces near about 2 liters of waste for every 1 liter of purified water. However, this does not suggest that the water purifier which you have purchased is not a good water purifier. - Reviews That Matter
