Buying Water Purifier

The quality of your water supply will determine how many stages of filtration you’ll need to obtain the purest water for drinking and cooking in your home. Purifying water is a multi-filtration process that involves passing various harmful sediments through many membranes to get clean water. Water purifiers come in a variety of shapes and sizes, each with its own set of features and requirements. RO and UV systems both use energy and can remove inorganic compounds as well as the odour of contaminated water. Activated carbon and sediment cartridge filters remove unpleasant smell and sand without the use of electricity, however they are ineffective at removing inorganic salt.

Types of Water Purifiers

Before you purchase a water purifier in India, there are a few things you should know. The contaminates, metal particles, and hardness of water in your home influence which water purifier you should choose. We’ll discuss about various types of water purifiers, their benefits, and drawbacks, how they work, and what contaminants, metals, and impurities they remove. Water purifiers are grouped into five categories based on the procedures used to purify the water.

Reverse Osmosis (RO) Water Purifier

To filter water, a RO water purifier uses a semipermeable membrane. The water is pumped through the RO membrane by a water pump, which pressurises the raw hard water to allow it to pass through. Dissolved solids such as arsenic, fluoride, lead, chlorine, nitrates, and sulphates are caught and trapped in the RO membrane during this process, resulting in purified water.

RO water purifiers are most effective at removing dissolved particles and pollutants from hard, salt water. Metal particles such as arsenic, fluoride, lead, chlorine, nitrates, and sulphates are removed by the only RO water purifier. If you have this type of home water, simply get a RO water purifier and rest assured that you will be drinking purified, safe water.

UF(Ultrafiltration) Water Purifier

Ultrafiltration, or UF, uses hollow fibres in a membrane consisting of a thin layer of material capable of separating water from other particles in the water. When water passes across the UF membrane, suspended solids, bacteria, and viruses stick to the membrane, trapping them and retaining them. However, UF does not remove chemicals present in water, it is therefore suitable for the areas where chemical contamination is low.

As UF does not remove the dissolved salts found in hard water, the water remains hard both before and after purification. Therefore UF does not work on hard water.

UV Water Purifier

UV (ultraviolet) water purification is a proven technology that can remove disease-causing bacteria, pathogens including bacteria, viruses, and cysts in water. During the purifying process, this eco-friendly method does not employ any toxins. A UV water purifier is constructed out of a UV light tube through which water to be purified should pass. Ultraviolet (UV) light damages and inactivates microorganisms such as bacteria and viruses when they are exposed to UV radiation from a UV lamp. The dead germs remain In the water, but they are no longer harmful.

Low TDS (Total Dissolved Solids) water, such as lake or river water, is perfect for UV water purification. UV water purifiers can’t even handle hard water with high TDS levels. UV water purifiers, like UF water purifiers, do not remove contaminants in water such as chlorine, arsenic, and fluoride.

Activated Carbon Water Purifier

Activated carbon is a type of carbon (coal, coconut shells, nut shells, and wood) that has been broken down into small pieces. Activated carbon is usually generated from charcoal. The “Adsorption” feature of activated carbon is used to filter the water. During the adsorption process, any chemicals, or metals in the water stick to the surface of the activated carbon. When water flows through the Activated Carbon, chemicals such as chlorine and other pesticides adhere to it, and the purified water is transferred to the bottom of storage tank.

Most pesticides and heavy metals that cause disease in water are removed by activated carbon. Chemicals that make water taste and smell foul are also cleaned by activated carbon. When it comes to removing chlorine from water, activated carbon is the most effective.

Sediment filter

This is a pre-filter, which means it is used in combination with other water purifiers such as RO and UV. Sediment is the material that is collected at the bottom of the water or liquid. Sediment might be rust flakes from metal pipes, sand, or mud particles, and it filters water to remove turbidity. The sediment filter captures unwanted dust and mud particles in the water.

Majority of sediment filters in India are made of cotton and polyester fibres. Sediment filters are rolled and stored in a plastic-sealed housing container. Sediment filter is located just before any other water purifier inlet. When dirt and dust particles pass through the sediment filter, they are trapped.

How to Select the Best Water Purifier?

With many options in the market, people are frequently confused when it comes to purchasing a water purifier for their homes. It is a significant decision because it affects our families’ health and well-being. So, how do you choose the best water filter for your household?

Let’s go over few easy steps:

  1. Water Quality

 Most of the water supplied to your home is hard water, which means it contains a high level of TDS (Total Dissolved Solids). TDS in water is a mixture of organic and inorganic elements, such as minerals and ions, that are dissolved in a specific amount in water. Inorganic salts such as calcium, magnesium, potassium, sodium, bicarbonates, chlorides, and sulphates are found in total dissolved solids in water. An RO (reverse-osmosis) system is the best water purifier for removing these inorganic compounds. Since the pore size of a RO membrane is .0005-micron, dissolved solids cannot exist in your drinking water.


  1. Water Pressure

 The type of filter you need depends on the flow velocity of the incoming water supply. With high water pressure, a reverse osmosis system would operate well. Water pressure is affected by the height of your building as well as other factors such as clogged filters and blocked pipes. A pressure of 5-40 pounds per square inch is required for most water purifiers. If your home’s water supply has low pressure, a booster pump can be used in connection with a RO system. If your water supply has less TDS, you could use an activated carbon purifier instead.

  1. Storage capacity

Analyse your family’s daily water consumption to determine the purifier’s required capacity. Purifiers with a large water storage capacity perform effectively in areas where electricity varies frequently.

  • For 2-4 members we recommend a storage capacity of 5-8 litres
  • For 4-6 members we recommend a storage capacity of 8-10 litres
  • For more than 6 members, a storage capacity of 10 litres is recommended
  1. Electricity

 When it comes to water purifiers, electricity is important. Many of them cannot function without electricity, making them unsuitable for houses with severe power outages. If there is no electricity, an ultraviolet (UV) filter will not work since it relies on energy to produce ultraviolet radiation that kills bacteria. An RO system would not function without electricity because it relies on electricity to supply sufficient water pressure to the RO membrane. Activated carbon purifiers, like sediment filters and ultrafilters (UF), do not require electricity. Non-electric purifiers can only remove some of the chemicals dissolved in water, as well as germs and sand, whereas RO and UV systems can remove TDS and bacteria that cause waterborne diseases. Water purifiers that run on electricity are the best option for houses with uninterrupted electricity supply.

  1. Purification technology

Heavy metals such as lead, arsenic, magnesium, copper, and iron can be harmful if large amounts are consumed in contaminated water. These metals are more common in water because of the rise of industrial and city infrastructure. Contamination with nitrates is also a major concern. Reverse osmosis reduces dissolved and suspended pollutants, thus it’s a good idea to invest in a RO system. Another type of filter to consider is an ultraviolet (UV) filter, which disinfects the water. With the UV lamp’s light, dangerous bacteria cannot multiply in a UV filter. You can also opt for a UV purifier that is based on RO. Another method of purification is to combine a RO and a UV filter with an ultra-filter (UF), which aids in the removal of suspended germs and is most effective when the water source is TDS-free. For places with high TDS levels, there are several RO systems with mineral cartridges.
