Drinking clean water regularly is important for healthy living. Just like air, water also gets polluted or contaminated. It is common knowledge that a lot of harmful substances are often present in regular water systems which may contaminate your water. Drinking water may contain contaminants like lead and arsenic as well as TDS. Unclean and unsafe water is behind a lot of diseases and health problems in India such as jaundice, cholera and typhoid. Surveys show that TDS level is above the permitted level in a lot of Indian regions including Delhi, Bangalore and Mumbai. Hence, the emergence of water purifiers to ensure clean and safe water essential for a good health. All you need to do is to install a water purifier in your home and start enjoying clean and safe water.

This article will highlight everything you need to know about water purifiers; from their types, benefits that will help you determine the best water purifier in India.

Water TDS Levels

Water is a great solvent that easily picks impurities like Totally Dissolved Solids (TDS). TDS contains inorganic salts like sulphates, calcium, magnesium, potassium, sodium and chlorides. TDS comes from natural sources like sewage, urban runoff, chemicals used in treating water and so on. Nowadays, we the emergence of advanced water purifier systems, you can adjust water TDS levels.

The lower the TDS level in water the better it is for drinking. If TDS level is lower than 300 ppm in water then it is best for consumption. If the TDS level in the water is above 500 ppm then it is safe for drinking. You can measure the TDS levels in water using a TDS Meter.

Other contaminants that are usually present in water include:

  • Bacteria resulting from spring runoffs, heavy rains, wear and tear of water systems, etc.
  • Nitrates resulting from agricultural activities. Excess consumption with nitrate-filled water may lead to Blue Baby Syndrome.
  • Herbicides and Pesticides resulting from contamination from agricultural and home activities.
  • Coli resulting from human sewage and animal faeces contaminating water sources.

Health Problems Caused by Drinking Unclean and Unsafe Water

You may suffer from a couple of health problems when you drink unclean and unsafe water. The gravity of these health problems depends on factors like health status, age, amount of water, contaminant type, etc. However, you can eliminate these threats by simply install a water purifier in your home. These health problems include:

  • Nausea
  • Vomiting
  • Cramps
  • Diarrhoea

Types of Water Purifiers

Water purifiers come in 3 major types. They include; gravity based (UF) water purifiers, UV water purifiers and RO water purifiers.

Gravity Based Water Purifiers: These purifiers make use of gravity to make water clean. They are ideal for water with low TDS content. Gravity based water filter prices range from Rs 1000 to Rs 5000. Gravity based water purifiers don’t need electricity to function unlike the UV and RO water purifiers, though they are not as effective as them. If you have a low budget and your water comes from treated sources or municipality, then the gravity based water purifier is an ideal choice for you.

Gravity based water purifiers also filter water using the Ultra Filtration (UF) membrane. Ultra Filtration membranes are like Ro membranes but they have bigger pores that can’t get rid of dissolved salts in water.

These water purifiers don’t just function without electricity; they are effective in removing microorganisms from your water completely.

Key Features

  • They do not require electricity.
  • These water purifiers remove and kill all viruses and bacteria in the water.
  • They can purify water using normal tap water pressure.
  • UF water purifiers cannot get rid of dissolved salts.
  • They can work with dirty turbid water.

UV Water Purifiers: These types of water purifiers make use of Ultra-Violet radiation technology to make sure water is clean by eradicating disease-causing water-borne organisms. They are slightly affordable. However, these water purifiers do not make provision for storage and cannot remove heavy chemicals or metals like iron, nitrates and arsenic. These water purifiers are also unable to get rid of the smell that comes with contaminated water.

Key Features

  • They require electricity to work.
  • These water purifiers kill all viruses and bacteria but their bodies remain in the water.
  • They can purify water using normal tap water pressure.
  • UV water purifiers cannot get rid of dissolved salts.
  • They can only work with clear water.

RO Water Purifiers: RO is short for Reverse Osmosis. It simply involves forcing water all the way through a semi permeable membrane that filters out some water contaminants which depends on their sizes.

RO water purifiers are effective for removing organic chemicals including lead, copper, sodium, nitrates, arsenic and municipal additive fluoride. However, they aren’t as effective as ultra violet filters against viruses and bacteria. They are important in areas with high contamination levels. Check Amazon for the cheapest RO water purifier prices available.

Key Features

  • They require electricity to work.
  • These water purifiers remove and kill all viruses and bacteria in the water.
  • They need electricity to boost tap water pressure.
  • UF water purifiers remove dissolved salts.
  • They come with a pre-filtration system that allows them to work with dirty water.

In recent times, some companies now manufacture water purifiers made from combined technologies, e.g. RO + UF or RO + UV or RO + UF + UV. These types of water purifiers are more effective than those using a single technology.


Once you learn one or two things about water purifiers, the next step is to buy one that is best suitable for your home needs. This can prove to be a difficult decision because of the plethora of water purifier brands and models in the Indian market. We came up with some factors that will guide you in buying the ideal water purifier for your home. These factors include:

Type of Water Purifiers: As you already know, there are 3 major types of water purifiers with different unique technologies. Gravity based water purifiers are the most affordable and cost between Rs 100 and Rs 5000. They don’t need electricity to clean water. You can also use gravity based water purifiers even when TDS level is low. However, they are not as effective as RO water purifiers as they cannot get rid of some dissolved impurities in water.

RO water purifiers can get rid of all kinds of toxic chemicals, dissolved salts and heavy metals from water; they are the most effective water purifiers. However, they cannot get rid of bacteria and viruses that cause the diseases. These water purifiers need electricity to clean water. However this does not stop them from being the most popular type of water purifier in India as the Municipality supplies water already treated of viruses to most parts in India. The best RO water purifiers are usually more expensive than Gravity based water purifiers.

All these water purifiers have their strong points, so go for the one whose strong points top your scale of preference and align with your interests.

UV water purifiers cannot get rid of dissolved salts from water but are the best when it comes to killing all kinds of viruses, germs and microorganisms. They require electricity to clean water.

Check online for detailed water purifier comparisons before making a final decision on the water purifier type to buy.

Electric Water Purifiers or Non-Electric Water Purifiers: Electric purifiers guarantee 100% clean and purified water. However, they require electricity at all times before they can work. They are also quite expensive. Electric water purifiers include; UV, RO, RO-UV and RO-UV-UF. If you stay in a neighbourhood where electricity supply is far from constant, then it is advisable you opt for a non-electric water purifier instead.

Non-Electric water purifiers are easy and simple to use. They can get rid of all impurities and most germs from water, but they aren’t as effective as the electric water purifiers. Non-Electric water purifiers also come in some portable sizes which allows them to be easy to move around like in an emergency.

Capacity: Water purifiers come with storage for purified water to ensure water is readily available at all times. If you have a large family, you should obviously buy a water purifier with a large capacity. But is your family is small, you can buy a water purifier with an average storage capacity of 5-7 litres.

Maintenance: Water purifiers require maintenance every 3 to 4 months. So after considering the size of your family, you should also consider maintenance costs of the water purifiers so avoid spending a lot of money in the long run. You can check reviews from online stores like Amazon and Flipkart for maintenance cost of water purifiers.

After-sales service: Poor after sales support from manufacturers may cause difficulty when it comes to servicing your water purifier. Many companies that manufacture water purifiers are guilty of poor after sales service. Ensure you buy a water purifier made by a top brand that offers great after sales support like Kent, Tata, Pureit, etc.

Customer Ratings and Reviews: Before setting out to buy any water purifier, make sure you check reputable online stores like Amazon and Flipkart for customers’ ratings, reviews and recommendations. In other words, find out everything people are saying about each water purifier. This will go a long way in helping you to select the best water purifier for home use.

Warranty and Installation: Ensure that the water purifier you want to buy comes with a warranty. Most water purifiers come with 1 year warranty. Also installation is usually free of charge; most reputable companies bear the cost of installation for customers.

Frequently Asked Questions about Water Purifiers

What is Reverse Osmosis (RO) water purification?

RO water purification entails the passage of impure water all the way through a semi permeable membrane which is capable of trapping impurities like TDS, heavy metals and other impurities.

It works using a special type of pump to force water all the way through the membrane which does not permit the reverse of water. It is one of the most commonly used water purification technologies. However, you may need to combine it with some other water purification technologies for it to work at its optimum level.

Why should I combine RO and UV technologies?

RO purification process is very effective for cleaning water; however it cannot remove all microorganisms, viruses and bacteria. This creates the need for an additional purification technology to ensure a 100% purification process. The UV purification is best fit for that role. When you combine RO and UV technologies you get the purest form of water.

What is TDS?

TDS is short for Totally Dissolved Solids. These days, you can hardly find water in its natural form. There are industrial and human contaminations everywhere as well as chemicals such as pesticides in the soil that contaminate water sources. Hence, there are a lot of dissolved solids present in water that normal sediment filters cannot remove. TDS up to a certain level might not be harmful but the moment it crosses the limit, it can be very dangerous to human health if consumed.

How do I measure TDS level in water?

Special meters are available to help you measure TDS level in water. If the TDS is below 500 then the water is safe for consumption. It is only under certain circumstances that you can consume water whose TDS level is up to 700. You should never drink water with a TDS level that is above 900.

What are TDS modulators/controllers?

The RO membrane effectively removes dissolved impurities. To do this, they get rid of TDS to a large extent which makes water very pure. However, drinking water requires some essential salts like magnesium and calcium.

The TDS controller helps to supply the output water with these essential salts thereby ensuring that water is not only healthy, but also safe. TDS controllers also make sure that TDS levels don’t rise to a high abnormal point.

What is a Mineralizer?

The RO membrane does not only remove essential salts, it also removes essential minerals. The mineralizer replenishes the minerals the water lost in the RO process. The mineralizer also maintains your water’s pH balance by introducing some form of alkalinity which is essential for making water tasty and healthy for drinking.

Why do I need AMC for my water purifier?

Most water purifiers’ equipment like UV lamps and water filters are expensive to maintain. They can handle different water sources but suffer a lot of wear and tear as a result of the accumulation of impurities. Excess accumulation may cause the water purifier to malfunction which prompts regular replacement of its filters. The AMC (Annual Maintenance Cost) helps to elongate the life of the water purifier filters. Normally, average maintenance cost is around Rs 4000 per annum.

What Would Be the Annual maintenance Cost for Water Purifier?

Annual Maintenance cost of a water purifier varies among water purifiers. It depends on factors like labour charges, filter replacements and so on. However, the average AMC for the water purifiers on this list should be about Rs 5000. You can also contact the manufacturer of this water purifier for their different maintenance packages for best results.

How Do I Use Rejected Water?

The purification process suggests that rejected water is the most contaminated and polluted. Rejected water contains a lot of impurities. A lot of advanced water purifiers get rid of rejected water by draining. This is important because it is very unhealthy to drink rejected water; it can lead to several diseases. However, if you wish to use this water for other purposes like washing, you can store it in the water purifier.

Is It Safe to Buy Water Purifier Online?
