What Is The Effectiveness Of Water Purifiers In Removing Bacteria And Viruses?  

Will you see any other liquids if you look at a glass of water? If the water is cloudy, you might see some color changes but not enough to see any other contaminants or pollutants. The water appears clean and safe to drink.

Water must be purified before it can be used, regardless of whether it comes from a borewell or the municipal provider. High levels of TDS, which often contain harmful bacteria and viruses, are quite common in water.

Water-borne diseases can be spread by harmful bacteria and viruses in drinking water. This is a well-known fact. Water-borne diseases can affect people from different parts of the globe at different times. Malaria, Typhoid, and Hepatitis A are some of the most well-known waterborne diseases. The presence of harmful microorganisms is one of the major causes of water-borne disease.

Although municipal water providers disinfect the water before it is delivered, microorganisms can still be found in pipes and storage tanks that could cause contamination. It is important to purify water at home before it can be used for drinking.

How Can You Tell If Your Drinking Water Has Been Contaminated?

It is hard for naked eyes to see the impurities in water. However, there are a few indicators that water might not be safe to drink. These are signs to look for:

  1. Verify if water has strange tastes
  2. Verify that the water does not have an unpleasant odor
  3. Check the color of the water to see if it is cloudy or muddy.

If you see any of these signs, your water contamination levels may be higher. Even if these signs are not present, it’s still recommended that your water be tested for TDS or other impurities. This will allow you to determine the presence of contaminants in your water. The most common way to find out if your water has harmful pathogens is to test for Coliform bacteria.

What Types Of Bacteria And Viruses Are Found In Drinking Water?

Some bacteria and viruses can be harmful to your health. It is important to get rid of microorganisms from the water before you consume it. Water can contain many pathogens, including viruses, bacteria, and parasites. Many of these may have both short-term and long-term effects on your health. Some can cause stomach pain, diarrhea, and viral fever. Others may have long-term effects on your health.

Here is a list of common microorganisms found in water, according to

  • Bacteria – Coliforms, Legionella, Enterococci, Vibrio, Salmonella, E. coli, Shigella
  • Viruses – Rotaviruses
  • Enteroviruses – coxsackieviruses, polioviruses, echoviruses
  • Parasites: Giardia and Entamoeba.

To make the water safe for drinking, these microorganisms must be removed from the water. How can you get rid of pathogens in water?

Water Purifiers Can Be Your Best Option!

What Is A Water Purifier?

In today’s commercialized world, it is difficult to find clean and pure water. Rapid urbanization and deforestation have led to an increase in the pollution of water resources. The water we drink is now more vulnerable to harmful contaminants. It is therefore important to purify water before it is consumed.

Water purifiers can remove undesirable biological and chemical contaminants, suspended solids and particulate matter, gasses, and pathogens from tap water. Water purification techniques used in the past included distillation, sedimentation, and filtration. The modern water purifiers of today are more advanced in terms of purification technology. Water purifiers that are good can remove excess salts, microbes, and other harmful metals. This makes it safe to drink.

What Are The Various Types Of Water Purifiers Available?

There are many water purifiers on the market. These water purifiers are designed to remove impurities from water. However, there are differences in how each technology works and what impurities it can treat.

3 The main types of purification technologies are:

  1. RO Water Purifiers
  2. UV Water Purifiers
  3. Water purifiers UF and MF

Water Purifiers Based on Gravity:

Gravity-based water purifiers are one of the most efficient and straightforward purification methods. This purifier is designed to remove visible particles and other particulate matter. Activated carbon modules can also be used to remove bacteria and viruses from gravity-based water purifiers. It is known as a Gravity-based purifier because it uses gravity and a water filter system to filter the water. These water purifiers don’t require electricity or continuous running water, unlike other purifiers.

RO Water Purifiers:

Because it can remove high levels of impurities and TDS, RO (or Reverse Osmosis) is one of the most advanced water purification technology. RO is a combination of a semi-permeable membrane and a multi-stage purification process to eliminate different contaminants from the water. RO technology can remove TDS (Total Dissolved Solids), which is made up of minerals, vitamins and harmful metals. It also contains chemicals, biological contaminants as well as particulate matter, suspended substances, pathogens, and other hazardous materials. It needs electricity to function and is designed so that all impurities are removed before it can send out purified water.

UV Water Purifiers:

The main purpose of UltraViolet water purifiers is to remove pathogens such as viruses, bacteria, and parasites from the water. UV, as its name implies, uses UV rays in order to kill microorganisms. It also provides safe drinking water. The electricity can also be used to power UV water purifiers. In order to complete the purification process, ultraviolet technology can often be combined with RO technology such as RO+ UV water purifiers. The presence of ultraviolet technology will ensure that water does not contain harmful microbes.

But, you might wonder if all purifiers can remove all kinds of impurities.

No. Each technology is designed to remove specific types of impurities. RO water purifiers are able to remove more contaminants than other technologies. Many people prefer to purchase RO purifiers for household use.

Can All Water Purifiers Kill Bacteria And Viruses?

No. Although water purifiers claim to eliminate microbes, this cannot be said for water purifiers that are UV water purifiers. Yes, there are many water purification systems. A RO is another water purification system that can remove various contaminants, but it also requires technology to eliminate pathogens.


You should consider the TDS levels of the water and whether it contains any other harmful pollutants. If you notice a high level of TDS, then RO water purifiers are recommended. Water purifiers are best if you find a lower TDS but have more pathogens. To ensure safe drinking water, you need to purify the water using multi-stage purifiers such as RO+UF.
