Water Purifier Buying Guide

A good water purifier offers safety from numerous waterborne diseases like viral fever, cholera etc. when you drink the impure water. So it is important to consider the key factors like capacity, cleaning technology, and filters before you wish to have water purifiers in your home. Read on to know how these factors greatly helps in improving the quality of water in purifier.

1. Source of Water

This has to be the first factor to consider while choosing a water purifier. Which type of technology is suitable will depend on the water supply of your home either it can tap water, bore, ground or municipal water. Because it helps to understand whether you need to remove dissolved salts or just kill the microorganisms.

2. Quality of water

Everyone has to know about the quality of water they are drinking so that they can set free from dreadful diseases. In general, you can check the quality of water by measuring pH, bacteria, TDS and many more.

For an individual it is not possible to check all the parameters. Hence you can measure the level of TDS- Total Dissolved Salts using the TDS meter which is very easy.

TDS-Total Dissolved Salts of water

Total dissolved salts (TDS) is a measure used to calculate the softness or hardness of the water based on impurities present in it. It is measured in PPM-Parts Per Million.

Major components of TDS include nitrate, calcium, phosphate, mercury, cations, anions, and other heavy metals. These substances are very harmful and can never discard them from our body.

When you use the TDS meter, it will level allow you to check for the level of TDS present in the water from time to time. Given below table will give a clear idea about the TDS levels and the type of water for that particular range. Check it out.

TDS Value parts per millionRating
Between 50 - 150Excellent
150 – 250Good
250 – 300Fair
300 – 500Poor
Above 1,200Unacceptable

3. Types of Water Purifying Technologies

There are  different types of water purifying technologies like Reverse Osmosis, Ultraviolet, Ultra filtration, Activated carbon, distillation and ion exchange. Given below are top 5 water filters that we have explained them in detail so that you can choose as per your purifying requirements.

a. Reverse Osmosis (RO)

If your water source has high TDS value, then you have to choose RO purifying technology. This technology removes dissolved salts present in the water. It has the capability of reducing TDS level from 1000 to 20–30.

In this purification method, water passes under high pressure through a semi-permeable membrane which removes the dissolved impurities. The RO membrane has approx. 0.0005microns pore size which allows only water molecules to pass through it and remaining any other contaminants will be rejected.

RO water purifiers contain pre-filtration which purifies dirty and mud water as well. In this type of water purifiers, the water wastage will be high and they require electricity to work.

b. Ultraviolet (UV)

If your water supply doesn’t contain any dissolved salts, then you can choose this type of water purifier. Ultraviolet water purifying technology uses a UV bulb to kill the harmful microorganisms. When the water passes through a UV bulb, the UV rays will kill the bacteria, cysts, and virus present in them.

Though these water purifiers are efficient in removing 99% of microorganisms in the water, they cannot remove the dead bodies of it. Hence UV filters are often called as

budget water filters

These type of water purifiers need electricity to work. They are not capable of removing dissolved salts, dirt or turbid water as the bacteria can protect itself from UV rays with the help of dust particles.

c. Ultrafiltration (UF)

This technology is very similar to RO water purification process with only difference in the membranes. The membranes used for ultrafiltration have large pores than that of RO.

UF purification process has the capability of removing cysts, bacteria and harmful particles like mud, dirt and turbid water. However, it cannot purify the dissolved salts and heavy metals present in it. This type of water purifiers doesn’t need electricity to work.

As you have got an idea of water source, TDS levels of it and different technologies present in the market, based on these factors you can easily determine which water purifier is suitable for you. Below is a quick guidance for the same…

SourceTDS LevelFilter
Municipal Water Supply1 – 200 PPMUV and UF
Ground Water Supply200 – 2000 PPMUV+UF+RO
Multiple Sources1 – 2000 PPMUV+UF+RO+ TDS Regulator

If you are unaware of the water source type, then you can use TDS meter to check the levels. Or else you can apply for a home demo of water purifier, they will help you know the TDS levels and type of filter suitable for it.

d) Activated Carbon

Activated carbon filtering is a method that uses a bed of activated carbon to remove impurities present in the water. Though it may not eliminate every possible contaminant, can effectively remove the heavy metals like lead.

They are of size 500-1000 nm with surface area of 1000 sq.m per gram. With its surface nature it is capable of adsorbing organic impurities from water and catalyst decomposition of chlorine-free. It can be applied in pre-treatment cartridges, composite vent filters, and final purification cartridges.

How it works?

When the water is passed through the active carbon water purifier, it completely removes the chlorine and other harmful organic compounds present in the water. It also improves the taste of water by deterring the bad odours.

During this process, some of the pollutants flow back into the water. It is called Breakthrough. When it happens the pollutants in treated water is higher than the raw water and the cartridges must be replaced.

The activated carbon filters really work for more litres of water and is also based on the quantity of contaminants present in the water. And the only disadvantage of using carbon filters is that it can breed the microorganisms present on the filter.

e) Gravity Based or Candle Filter

Gravity based water purifier implements pressure filtration mechanism to purify the water. It works on the principle gravity and does not consume any power for the purification process. These are pretty much suitable in areas where the TDS level is low in water.

The working of gravity based water purifier is such that it has 2 compartments- 1 for raw water and the other for pure. Initially the water flows from up to down sections via gravitational force acting on the device. During this process, it comes across carbon filters and micro fibre mesh to remove the unwanted particles.

Sometimes it may even undergo ultrafiltration which is the most advanced process to deter bacteria, virus, and other microorganisms present in drinking water.

The major drawback of this gravity water purifier is that it uses 2- compartments and the user has to pour water manually into the device. However, there are some advanced models to go with that features automatic options and in less budget.

4. Capacity

If you live in areas where power/water supply is an issue, then storage capacity of a water purifier plays an important role. Depending on the water consumption, you have the select the capacity of a water purifier.

For example, on average for a family of 4 members, a water purifier of 7 litres is good enough. And for a family of 5 – 10 members, you may need up to 14 litres of tank capacity.

5. Maintenance

While selecting a water purifier, it is important to check the maintenance cost. Make sure it is not high as you end up spending more amount of money. Usually an annual maintenance is important to ensure the water purifier is working in proper condition

6. Warranty and Installation

Usually most of the reputed brands provide free installation and warranty for certain period of time. There are some companies that charge for installation. So, ask a representative about the installation and warranty details before purchasing a water purifier.

7. Is the Brand Reliable?

Pay attention to the brand you are purchasing. There are several bogus brands in the market that sell cheap quality products. Though a reputed brand water purifier may be a little costly, but their products are reliable as they use high quality filters and membranes in the product. Also their dedicated customer service is helpful in clarifying your doubts and providing after sale services.

8. Electric or Non-Electric Water Purifiers

Most of the people believe that electric water purifier is more efficient than non-electric. It’s totally wrong. Both have the same functionality to purify the water. And the difference can be observed from the filter it uses, tank capacity and speed operation.

In electric water purifier, it uses RO, and UV filters when subjected to the external power supply. As the RO filter wastes lots of water in the purification method, it also controls the TDS level. It requires a very high maintenance cost and to be installed by the professionals.

Whereas the non-electric water purifier uses carbon and gravity filters. Compared to electric water purifiers, wastage of water is very less and the maintenance cost is very low. Even a newcomer is able to install the device effortlessly. And the only thing we didn’t like about the non-electric water purifier is that there is no TDS controller option.

9. Budget

You must also look out for the money that you want to spend on water purifiers. Basic models do not cost much, but the ones with the advanced purifying filters are too expensive.

If you find hard water in your home, then is essential to have the purifier with all sorts of filters.  Are you the one who don’t want to spend huge amount on water purifier then go with the best budget water purifier prototype that have less number of features.  Be sure, it should match with the purifying requirements.

As water purifier is a long term investment, it is better to make sure the water purification body is attractive, rust proof, durable and easily goes with the kitchen decor. Different materials like aluminium and ABS are used in the water purifier. For complete safety, durability and hygiene, it is better to choose steel. Aluminium can react with salts and minerals present in the water to produce aluminium oxides which are harmful for brain.

4. Global Certification

As many local assemblers import low quality components from non-reputed Chinese suppliers, it is better to check for global certifications like WQA (USA) Gold Seal mark for RO or UV systems.

5. Display

These days, all purifiers come with display panel that shows the options like tank full/empty, purifier on/off by using indicators. Some advanced purifiers possess fault alert, filter change, TDS levels, etc.

6. Storage tank

Storage tank stores the purified water for further usage. Many of the storage tanks are made with food grade, non-toxic material and some with high-end stainless steel material.

It is also important to check storage tank capacity for prolong usage (2-3 days) than operating daily.
