There are three steps to choose the most suitable water purifier for your house.

  1. Find out the quality and source of your water supply.
  2. Based on the Water Test results, select the type of water purifier. As you know there are different technologies water filters available in the market and it is important to choose the right water purification system based on the quality water and source of the drinking water.
  3. Finally to buy the water purifier,

Know the Sources of Water and quality of water

Wherever the water may come from, it is important to consider the TDS (Total Dissolved Salts) present in the water. This greatly influences the type of filter chosen. TDS is measured in ppm (parts per million)

TDS is the total dissolved solids in the water. Water can dissolve most compounds like salts, minerals, chemicals, and other impurities. The most common constituents of TDS are calcium, phosphates, nitrates, sodium, potassium, chlorine and iron.

The main constituents of TDS are calcium, nitrates, phosphates, sodium, potassium, chlorine and iron. The TDS level mainly influences the choice of your water filter

Before you drink water, you need to check hardness and softness of the water, and we check with total dissolved salt (TDS) meters which are available in the market. Below is the recommended level of total dissolved salt

Above 400 -very hard water needs to be purified
150 – 400- hard needs purification
80 – 150- soft and safe for drinking
.

Based on the TDS rating of the water, water filters have different technology to filter water

Different types of water purifying technologies

  1. UF (Ultra Filtration) Technology,
  2. UV (Ultraviolet) Technology,
  3. RO (Reverse Osmosis) Technology,
  4. EAT (Electro Adsorption Technology)

After this, choose which purifier unit – electric or non-electric.

that:- some filters require electricity to function.

Different types of water purifying technologies

UF (Ultra Filtration) Technology – Gravity-based Water Purifier

Gravity based water purifiers are budget-friendly and don’t require power to operate. You can use gravity-based water purifiers if the TDS level in your area is low. The water purifiers are ideal for removing bacteria, dust, chlorine, and cysts from water

UV (Ultraviolet) Technology

. UV water purifier uses a high power UV lamp to disinfect water and remove contaminants from water. UV water purifiers are ideal for purifying tap and municipal corporation water. However, UV water purification can’t remove dissolved impurities from water.

Activated Carbon Water Purification Technology

Activated carbon water purifier comprises of charcoal granules, absorbs the pesticides as well as herbicides. It works without electricity. Activated carbon filter works by removing the harmful chemicals such as chlorine present in the water when passing through the carbon granules. This improves the taste of water and removes any bad odor.

 RO (Reverse Osmosis) Technology

Reverse Osmosis Purifiers are ideal for areas that have a high TDS level. RO water purifiers can remove heavy metals, Flouride, Arsenic, and other toxic impurities from water. However, RO purifiers also remove some of the essential minerals from water which makes it important to ensure that the water purifier has a TDS controller.

EAT Technology (Electro Adsorption Technology)

  • EAT has five advanced stages of water purification which are as follows:
  • First Stage – External Prefilter removes solid particles like sand, silica, silt, dirt, and dust present in water and enhances the life of the filter
  • Second Stage – Mechanical Filter removes other suspended solids through a sediment mesh
  • Third Stage – Electro Adhesion Filter eliminates the impurities which carry a negative charge, removes the disease-causing germs such as bacteria, virus, and cysts.
  • Fourth Stage – Ion Exchange, where the activated carbon granules, remove the heavy metals like lead and arsenic
  • Fifth Stage – Electro Adsorption removes the harmful chemicals such as chlorine, pesticides, and endotoxins

It is available in both electric and nonelectric variants, and some EDT purifiers also come with storage tanks. This type of purifier is ideal for water which has less than 500 ppm TD

Types of Water Purifiers

Non-Electrical With Storage

These water purifying units have storage tanks to store water after it is purified through sediment and activated carbon filters. Useful in places where water supply is unreliable.

Non-Electrical Without Storage

Made of food-grade plastic, these water purifiers are directly fixed to the water tap. They are usually candle-shaped filter units that consist of a resin filter that has to be replaced once a month. They’re UF and Activated Carbon filters that run without electricity.

There are also personal water purifiers – water-bottle-sized, optimal active units that attract and remove waterborne pathogens. They are great for pure water anywhere, anytime, owing to their traveler-friendly size.

Electrical With Storage

Electric water purifiers are always connected to the water supply and run on electricity. They use sediment filters and activated water filters with UV or RO purification systems, which require electricity

Electrical Without Storage

Electrical units are also available without a storage tank. This type is quite popular – many units through the ’90s were of this type. Useful in places that have a steady supply of electricity through the year, the filtration quality is the same as of those with storage.

Factors to consider while buying a water filter

TDS Controllers

TDS controllers are often found in RO, UV and UF purifiers. The TDS regulator constantly senses TDS levels and selects the best purification process

Storage Capacity

When buying a water purifier, it is very important to take into account the storage capacity. If you live in an area that is prone to power cuts, you need a water purifier that has a higher storage capacity. The automated water purifiers start the purification process as soon as the water level in the purifier declines

Electricity:

 Although RO water purifiers are said to be the most effective, a big problem with these is that they need electricity to operate. This means that they can be useless in areas where power is erratic. The same is the case with UV water purifiers.if you are traveling to a remote place and want pure water, you can only carry the activated carbon water purifier as it is the most compact and needs no electricity to operate
