The Ultimate Guide to Buy a Water Purifier for Good Health

Given the health benefits of drinking purified, non-contaminated water, we’re certain that every money you spend on a reputable water purifier is a penny well spent.

Apart from that, there are hundreds of reasons to search for the best water purifier and bring one home with you; for example, water purifiers ensure:

  • Protection against life-threatening waterborne infections induced by contaminated water
  • Calcium carbonate, which gives tap water a strange flavor, is removed.
  • Scratches, spots, and scaling on the surface of your culinary utensils are minimal to non-existent.

Before you look for the different types of water purification technologies and decide which one is ideal for you, it’s important to understand the different sorts of toxins that are commonly found in drinking water.

The sort of pollutants found in your drinking water is mostly determined by the water’s source and delivery medium. Lakes, rivers, bore wells, harvested rainfall, piped municipal corporation supplies, water tankers, and other sources of drinking water are the most frequent.

The hardness of water, as well as the number of impurities such as dangerous pollutants, chemicals, and biological impurities such as bacteria and viruses, determine which water purifier is best for home.

Types of ImpuritiesMost Common Water SourceEffect on Drinking Water
Un-dissolved solids such as sand and mudRiver, borewell, or piped waterMuddy or turbid appearance
Dissolved inorganic salts like Sodium & PotassiumBorewells and seawaterSalty or brackish taste
Dissolved inorganic compounds like Calcium & MagnesiumBorewells and river waterHardness and scale formation
Organic compoundsLakes and pondsFoul smell or bad odor
Decontaminants like Chlorine       Municipal piped water supplyBitter taste
Biological impurities like bacteria & virusesPiped water where pipes are damaged, water tankersBiological contamination, waterborne diseases

What are the types of water purifiers?

RO (Reverse Osmosis), UF (Ultrafiltration), and UV (Ultraviolet) are three different types of water purifiers (Ultraviolet). Some water purifiers combine multiple technologies, such as RO and UV, to purify water. You must select the sort of water purifier that best meets your needs based on the TDS level. You might require a UF or UV water filter, or a mix of both, for low TDS water (200 ppm or less).

RO Water Purifier

In a Reverse Osmosis or RO water purifier, a pump forces high-pressure water through a semipermeable membrane with pores as small as 0.0001 microns into the RO chamber. Dissolved particles and contaminants are left behind as water molecules pass through to the other side. A separate outlet, known as a reject line, is used to discharge some of the input water and contaminants.

Other filtration elements, in addition to RO membranes, are used to improve the filtration process and extend the life of the real RO membrane. These filters are referred to as ‘Stages.’ The filtration process in a RO machine begins with Sediment Filter. The Sediment Filter purifies water by eliminating any suspended contaminants. The Activated Carbon Block filter is the second filter, and it eliminates chlorine, unpleasant odors, and adsorbs pigments. Water is pumped through a post-carbon filter after filtration by the RO membrane to improve the taste and appearance of the drinking water.

The most effective water filtration method is reverse osmosis (RO), however, if your water has  a TDS level of 200 ppm or below, a RO water purifier may not be necessary because it is expensive, wastes a lot of water, uses a lot of electricity and requires maintenance too. Many firms, however, have recently begun to offer water purifiers with a separate tank for storing discharged water, which may be subsequently used to wash clothing, dishes, or wipe the floor.

  • Gravity Water Purifier

A gravity-based water purifier does not require power and relies on gravity to force water through a membrane or filtration material. Gravity filters come in a variety of shapes and sizes, including UF, Carbon Block, Ceramic Block, and Non-Woven Media. Chlorine, cysts, dust, big sediments, and undissolved solids can all be removed with these water filters. These water purifiers should not be used if the TDS of the input water is greater than 500 ppm because they cannot remove dissolved solids or some viruses.

  • UV Water Purifier

UV water purifiers work by exposing bacteria and viruses to ultraviolet light, which kills them. The filtration procedure in these water purifiers is rapid. However, they are incapable of removing dissolved particles or pollutants from water. Furthermore, because the UV lamp’s intensity declines over time, it must be replaced every six months or a year.

Things to consider before buying a water purifier

Other factors to consider before selecting the proper water purifier model include the capacity of the storage tank, the substance of the storage tank, the ability to get hot and cold water, warranty, and maintenance costs.

Storage Tank Capacity

You’ll need to know how much water storage you’ll need once you’ve decided on the type of water purifier that best meets your demands and drinking water supply. Every day, each member of the household uses between two to four liters of water. As a result, you should figure out how much filtered water you’ll need all at once. If you live in a region where there are regular power outages, make sure you get a water purifier with a large enough tank to store enough water for at least a few hours.

Need Hot & Cold Water Facility in Your Water Purifier

After the purification process, certain water purifiers can provide both hot and cold water. Cold water from the water purifier can be consumed directly, while hot water can be used to clean cereals, fruits, vegetables, and other edibles. However, such water purifiers are typically found in the high-end category and cost more.

Warranty & Maintenance Cost

A one-year product warranty, a one-year RO + UF membrane warranty, and a six-month guarantee on sediment filters, carbon filters, and post-carbon filters are standard on most water purifiers. Some manufacturers offer a free AMC (Annual Maintenance Contract) for a period of one to three years. The AMC covers membrane and filter replacement every six months to a year, as well as labor and repair charges if anything goes wrong.

In terms of maintenance and repair, gravity water purifiers are the least expensive, while RO and RO+UV water purifiers are the most expensive.
