Understanding Water Purifiers: How They Work and Why You Should Buy One

Given the increasing concern about water quality, water purifiers are indispensable appliances for urban households. However, with many water purifier brands flooding the market, choosing the best one can take time and effort for homeowners.


In today’s world, drinking water undergoes various treatments to ensure its safety. Given the uncertainty of water sources, it becomes crucial to eliminate impurities like microplastics, fuels, and solvents that may be present in the water.


What are the most common types of impurities in water?


Contaminant Description Potential Side Effects
Microbial and organic contaminants Aluminum, ammonia, copper, mercury, silver, etc. Increased risk of water-borne diseases and illnesses
Chlorine/Fluoride Toxic chemicals added to tap water for disinfection Linked to cancer and potential impact on mental development in children
Metals Arsenic, lead, cadmium, iron, etc. Toxic amounts may leach from old pipes, potentially causing health issues
Industrial waste Pesticides, fertilizers, prescribed drugs, manures, fuel, oil, chemical solvents etc. Harmful effects on the body from everyday chemicals in the water
Side Effects of Water-Borne Impurities Acute: fever, vomiting, diarrhea, flu-like symptoms. 

Chronic: cancer, liver or kidney problems, reproductive issues

Potential threats to health depending on the level of contaminant exposure in drinking water.


Installing a water purifier at home can effectively address these issues. The best water purifiers in India utilise advanced techniques such as reverse osmosis, ultrafiltration, UV etc., to ensure thorough water purification and provide your family with safe and clean drinking water.


Types of water filters that remove various contaminants and impurities:


Water purifiers help remove contaminants from water, making it safe to drink. Various types of water purifiers are available in the market, and the choice of the purifier depends on the quality of water in your area, budget, and personal preferences. 


Here is an overview of different types of water purifiers:

Reverse Osmosis (RO) Water Purifier

RO water purifiers use a semi-permeable membrane to filter out impurities and contaminants from water. The membrane has tiny pores that allow water molecules to pass through while blocking larger molecules such as salts, minerals, and bacteria. 

Ultraviolet (UV) Water Purifier

UV water purifiers use UV rays to kill bacteria, viruses, and other microorganisms that may be present in the water. This type of water purifier consists of a UV lamp that emits high-intensity UV rays, which penetrate the cell walls of microorganisms, rendering them inactive. 

Activated Carbon Water Purifier

Activated carbon water purifiers use activated carbon to remove impurities such as chlorine, pesticides, and organic compounds from water. 

Microfiltration (MF) Water Purifier

MF water purifiers use a hollow fiber membrane to filter out impurities from water. The membrane has small pores that allow water molecules to pass through while blocking larger molecules.

Distillation Water Purifier

Distillation water purifiers use heat to vaporize water, which is then condensed back into liquid form, leaving behind impurities and contaminants. 

Ion Exchange Water Purifier

Ion exchange water purifiers use resin beads to remove impurities such as calcium, magnesium, and other minerals from water. The beads have a negative charge that attracts positively charged ions, removing them from the water. Ion exchange water purifiers effectively remove hard water minerals but cannot remove bacteria and viruses.


Here are different types of water filters that can be chosen based on the type of contaminants in your drinking water:


  • Inorganic contaminants: Membrane technologies such as microfiltration, ultrafiltration, nanofiltration, and reverse osmosis are commonly used to remove inorganic contaminants.


  • Biological contaminants: Various techniques can be used to remove biological contaminants, but their effectiveness may vary. These methods include boiling, FiltraPower technology, UV radiation, ultrafiltration, and reverse osmosis water filtration.


  • Radiological contaminants: Reverse osmosis is considered one of the best methods for removing radioactive elements from water. Other methods such as triple threat, ion exchange, and activated carbon can also be used.


It is important to have your water tested to determine the type of contaminants present before selecting the appropriate water filter for your specific needs.

Picking the Best Water Purifier 


The Pureit Vital Plus RO+UV+MP Water Purifier is a water purifier that uses a combination of Reverse Osmosis (RO), Ultraviolet (UV), and Microfiltration (MP) technologies to provide safe and clean drinking water.
