Water Purifier Buying Guide

Confused about which is the best water purifier for home? Because there are so many things to consider when buying a water purifier, we have collated a buying guide that will help you learn about different types of water purifiers and find the one that fits your needs.

1. Water Quality: The first thing to consider when buying a water purifier is the quality of the water supply you get in your home. The quality of the water supply depends on the water source. If the water supply in your home is supplied by municipalities and it comes from natural resources like lakes, river, and rainwater harvesting technique, then you’re getting soft water. If the water supply in your home comes from underground sources like borewells, tube wells, hand-pumps and wells then you’re getting hard water. The amount of total dissolved solids (TDS) is comparatively higher in hard water than soft water. If you’re getting hard water, opt for a RO water purifier. Go for a UV water purifier if the water quality is soft. If you are getting hard as well as highly contaminated water, you can opt for RO+UV water purifiers.

2. Types Of Water Purifiers: The most common types of domestic water purifiers are Reverse Osmosis (RO) purifiers, Ultraviolet Rays (UV) purifiers, Ultrafiltration (UF) purifiers and Gravity based purifiers.       

Reverse Osmosis (RO) water purifiers: Reverse osmosis (RO) is a water purification process that uses a partially permeable membrane to remove ions, unwanted molecules and larger particles from drinking water.

Ultraviolet Rays (UV) water purifiers: In a UV water filtration system, UV (Ultraviolet) rays are used to kill the harmful bacteria from the water. A UV water purification system typically consists of a UV light source with an output of around 254 nanometers that can effectively eliminate up to 99.99% of bacteria and viruses, including those associated with water-borne illnesses such as Typhoid, Gastroenteritis, Hepatitis, Flu, and Cholera.

Ultrafiltration (UF) water purifiers: Ultrafiltration (UF) is a membrane filtration process similar to Reverse Osmosis, in which hydrostatic pressure forces the water against a semi-permeable membrane. Suspended solids, bacteria, viruses, endotoxins, and other high molecular weight pathogens are retained, while water and low molecular weight solutes pass through the membrane.   

Gravity based water purifiers: Gravity based water purifiers are non-electric purifiers that use microfiber mesh, polisher modules, activated carbon modules and/or UF technology to remove impurities.    

3. Installation: A few water purifiers are designed to be used as a countertop kitchen appliance while some brands also manufacture water purifiers that can be hung on the wall to keep the countertop clutter-free. Decide upon a suitable place for your water purifier – countertop or wall and then make a final decision.

4. Electricity Needs: Based on their electricity needs, water purifiers are of two types – electric or non-electric. While electric purifiers need electricity to function, non-electric water purifiers can function without electricity and are usually gravity-based. Take into account the power situation in your area and then take the final buying decision.

5. Storage Capacity: If you reside in an area that has frequent power cuts or unreliable water supply or you live in a joint family, opt for a water purifier that has a larger storage capacity. This will ensure a continuous supply of pure and contamination-free drinking water.

6. Certification of Purity: Another point to consider when purchasing a water purifier is a certification of purity. Most brands these days usually give a certificate of purity with the water purifier. This certificate is a mark of the authenticity of the brand. It also ensures that the water dispensed from the water purifier is of high quality and therefore safe to drink. Water purifiers usually have one or two of the following certifications.

IS 16240: 2015 standard covers Reverse Osmosis (RO) based point of use water treatment system.      

IS 7402:1986 /2011 standard certifies that the ceramic filters used in the purifier can arrest impurities to the finest range possible, including particulate and bacterial impurities.

IS 14724: 1999 indicates that the purification process is carried out through a combination of UV film and rays.

IS 10500:2012 gives an assurance that the end product is free from coliform, pesticide residues and other chemical contaminants.

NSF, WQA, ISI, and CE are some of the other certifications to look for when selecting a water purifier.

7. After Sales Services: Water purifier require frequent servicing from time to time. Poor after-sales services can cause a lot of problems and the customers have to wait for a longer time to get their problems solved. Therefore, before making any final decision on which water purifier to purchase, do enquire about the after-sales services offered by the brand.

8. Digital Display: Most water purifiers come with basic display for purifier on/off, tank full, etc. Some advanced purifiers also come with an LED display that shows fault alert, membrane change, UV fail, TDS level indicator, purity indicator, etc.

9. Mineral Fortification Technology: Some advanced water purifiers come with a mineral fortification technology that adds essential minerals which enhances the taste, quality and also balances the pH of purified water.

10. In-built TDS controller: A few advanced water purifiers come with an in-built TDS controller that controls the TDS (Total Dissolved Solids) levels of water. When the TDS levels of input water are not so high, the TDS Controller can be used to increase the TDS of purified water to a healthy level. 

11. Purification Capacity: Purification capacity is the flow rate at which water is purified in an hour. A higher flow rate can result in unsuccessful purification of water while slower flow rate takes a lot of time to give you one liter of clean water. Therefore, go through the water purifier specifications carefully and look out for the purification capacity. Ideally, a purifier should give you anywhere between 12-15 liters/hour.

Frequently Asked Questions About Water Purifier

Are water purifiers safe?


Water purifying chemicals in liquid, tablets, or powder form are added directly to untreated water to decontaminate it. They act directly on harmful organisms to destroy them. When used correctly, water purifying chemicals are generally safe.

However, when used inappropriately or excessively, water purifying chemicals lead to immediate irritation of the mouth, throat, and stomach causing symptoms such as burning and irritation in the mouth and throat, nausea, vomiting, and abdominal pain.

What is the RO water purifier?


Reverse osmosis (RO) is a water purification process that uses a partially permeable membrane to remove ions, unwanted molecules and larger particles from drinking water. Reverse Osmosis filtration is the perfect solution if you’re looking to improve the taste, odor, and appearance of your water.

Which is better RO or UV?


Reverse osmosis (RO) is a water purification process that uses a partially permeable membrane to remove ions, unwanted molecules and larger particles from drinking water.

In a UV water filtration system, UV (Ultraviolet) rays are used to kill the harmful bacteria from the water. A UV water purification system typically consists of a UV light source with an output of around 254 nanometers that can effectively eliminate up to 99.99% of bacteria and viruses, including those associated with water-borne illnesses such as Typhoid, Gastroenteritis, Hepatitis, Flu, and Cholera.

Which water purifier is better for municipal water?


If the water supply in your home is supplied by municipalities and it comes from natural resources like lakes, river, and rainwater harvesting technique, then you’re getting soft water. Go for a UV water purifier if the water quality is soft.

How can we purify water at home?


The following are the common methods of at-home water purification:

1. Boiling
2. Use of Iodine solution, tablets or crystals
3. Use chlorine drops
4. Use water filter
5. Use Ultraviolet Light
6. Distillation

What are the impurities found in water?


Two forms of impurities are found in drinking water – suspended and dissolved:

1. Suspended impurities are suspended solids like mud, dust, sand, bacteria, viruses, etc that are not completely soluble in water and are present as particles.

2. Dissolved impurities are impurities like pesticides, arsenic & fluoride and heavy metals salts like mercury, lead, copper, cadmium, etc that are soluble in water.

What is the desirable quality of drinking water?


As per BIS (The Bureau of Indian Standards), the desirable quality of drinking water is water that has a TDS (Total Dissolved Salts) content of 500 ppm or less. If such quality is not available, the compromise level is water with a TDS of up to 2000 ppm.

When should the filter cartridges be changed?


The frequency of changing your filter cartridges depends on water quality and usage. If you get highly contaminated water supply in your home or filter large quantities of water, you should change your filter cartridges every 3 months. It is recommended to change your sediment, carbon and deionization cartridges every 6-8 months and RO membrane every 2 years.
