Do you know that viruses can harm your body by entering through your mouth if they are present in your drinkable water or if you are consuming water directly from your kitchen faucet without testing its quality? That sounds bad, right? Sounds like obtaining safe drinking water for survival has become a necessity, isn’t it?


Although packaged water is safe, there is a limit on the number of bottles a person can buy but can't ignore the usage of low-quality plastic. It has become crucial to get a RO water filter in order to obtain pure and clean drinking water for you and your family. On the other hand, Traditional water filters are deprived by the environment. Furthermore, certain ordinary water filters are inefficient and serve as breeding grounds for microorganisms. As a result, a reverse osmosis water filtration system is the ideal solution.


The reverse osmosis RO membrane is designed with a pore size of around 0.1 nm, whereas the diameter of a virus is between 0.02-0.25nm,making it significantly smaller to eradicate viruses.


The Reverse Osmosis Water Purification System is built around a RO membrane, that is formed on a high-pressure water principle. This allows water molecules to travel through the RO membrane while heavy metals dissolved salts, foreign matter, bacteria, viruses, and other contaminants are blocked. The RO membrane distinguishes between filtered and unfiltered water.


Pureit's RO membrane outperforms conventional RO membranes. It eliminates bacteria and viruses more effectively. It delivers clean, pure water for everyday use as a water-advanced technology filter. Bacteria tend to multiply every half hour in the water tanks of standard RO systems. Certain RO + UV filtration technologies can also help to prevent secondary water pollution from bacterial proliferation.

Types of bacteria present in water

According to Springer, E. coli (E. coli), Fecal Bacillus species, Corynebacterium, Pseudomonas, Giardiasis, Clostridium perfringens and Salmonella Typhimurium are some of the bacteria that can be found in tap water as well as pathogens. These bacteria can cause illnesses like diarrhoea, pneumonia, hepatitis A, typhoid fever, and other gastrointestinal issues if left untreated.


Let's look at some of the bacteria that can be found in your tap water and how to get rid of them!


Escherichia coli is a bacteria that causes diarrhea in people who consume contaminated water. It can be found in various places including homes, schools, and hospitals.

The most general cause of nutrition gastroenteritis is Campylobacter Jejuni (diarrhea). It is easily found in contaminated tap water, such as those found on farms, chicken farms, slaughterhouses, and live poultry markets.


  1. Fecal Coliforms are bacteria found in the stool that can cause gastrointestinal issues such as stomachaches or cholera.
  2. Pseudomonas Aeruginosa is a bacteria that can cause infections in the eyes and nose when consumed in large quantities. Notable side effects can also be seen through skin infection.
  3. Cryptosporidium is a protozoan that causes diarrhea when consumed and is spread by impure water. It can also be detected in tap water due to contamination from animal excrement, human waste, or food.
  4. Giardia Lamblia is a parasite that causes intestinal infections from the consumption of infected water.

How do get rid of these bacteria and viruses?

Reverse osmosis (RO) water filter can be used to eliminate germs and viruses. UV kills bacteria & viruses and RO membrane removes these bacteria and viruses.

By installing an efficient RO water filter

RO purification is one of the most effective ways to eliminate all forms of germs and viruses apart from boiling and chlorination. It filters out heavy metals, impurities, and organic matter from tap water, giving you pure, filtered water that is free from hazardous bacteria, viruses, and parasites from contaminated sources.


The all new Pureit Vital Filter series is a a next-GEN RO, this unique RO purifier offers Filtra Power Technology that is globally proven to remove numerous viruses, bacteria, cysts, chemicals and pesticides.


Unlike a normal RO purifier,its sediment and carbon filters harmful pesticides and absorbs bad taste odour causing organic compounds from water. RO membranes effectively does not allow any excess Total Dissolved Solids (TDS) to make your water tastier. The membranes also remove arsenic, fluoride, pesticides, heavy metals like lead and mercury along with bacteria, virus and protozoa cysts. Its efficient UV Sterilization deactivates upto 99% of bacteria and virus to give you 100% purified drinking water.


This device also consists of an RO membrane protector that safeguards the membrane components from scaling, foul smell and contaminants, ensuring the membranes last long. Also equipped with Mineral Enhancer Catridge that enriches water by adding essential minerals like calcium and magnesium, this device gifts your family sweeter and safer water through its advanced filtration.

What is the process of reverse osmosis?

It's crucial to understand how reverse osmosis works in order to comprehend what it doesn't remove and the basic advantages and limitations of a RO system.

One of the benefits of RO is that it works at the molecular level, which means it has a filter membrane so small that only water molecules or ions pass through it. This procedure usually results in some of the cleanest and purest water available. However, it does not always imply that it is a fail-safe water treatment method.

RO water can be used for cooking purposes as well, as bacteria or other harmful chemicals may be present in tap water.

How does the reverse osmosis process remove bacteria?

Reverse Osmosis (RO) uses high pressure to remove dissolved solids from liquids, resulting in an ultra-filtered solution of distilled water free of germs, viruses, and parasites. Most RO water purification systems combine filtering and precipitation to get the best outcomes by removing hazardous organisms like bacteria and viruses.

1. UV light can kill bacteria

The next step is to use UV filtering to remove any microorganisms from your tap water. This method is called UV bacteria eradication, it bacteria with ultraviolet light.

2. Bacterial removal with carbon block filters

As per a study by Royal Society of Chemistry - Bacteria, viruses, and other organic molecules like chlorine, volatile organics, herbicides, pesticides, and insecticides are eradicated in this stage.

3. Filtering tap water using a RO membrane to remove bacteria and other impurities

This process consists of using a membrane or filters with pores smaller than bacteria, removing bacteria, viruses (or any other dangerous compounds). This will eliminate all germs and other pollutants.

Is fluoride removed by reverse osmosis?

Reverse osmosis will successfully filter out fluoride because fluoride molecules are bigger than water molecules. Again, the RO filter's efficiency is dependent on adequate care and maintenance.

Importance and benefits of RO filtration

Reverse osmosis is a fantastic initial step in residential water treatment., RO can filter out the most dangerous contaminants, such as lead, arsenic, and other heavy metals, as well as bothersome dissolved hard minerals, from public water supplies.

In all cases, to get the best possible solution for your water treatment needs, it’s important to start with a water test to determine what’s in your water. Especially for reverse osmosis systems, it’s important to understand what is in your water (iron, calcium, chlorine, etc.) and in what quantity. Once you are aware of the contaminants and their average levels in your water supply, you’ll be in a better position to determine the right water filter for your home.


  • Germs are usually found in tap water, adding a RO system can remove 99.99 percent of all bacteria, viruses, and pollutants. Bacterial contamination is linked to polluted areas such as inadequate sanitation, purification, or chlorination ofthe water supply. If the tap water comes from a municipal system, the officials should disinfect it using standard filtration methods before it reaches your residence.
  • It’s important for people who have a weaker immune system to acknowledge the type of bacteria present in their tap water, and install an RO water system, as this could affect the consumer and develop symptoms when exposed to untreated water.
  • Although some water ultrafiltration systems are complex and time-consuming, a reverse osmosis filtering system is convenient to operate. Simply replace the filters and membranes according to the manufacturer's instructions. The purifier will even give you a reminder when it's time to order a replacement filter if you buy Pureit! MostThe membrane needs to be changed every two years, and filters every six to twelve months. The duration is determined on the calibre of the water in your area and the frequency of RO system use.
  • Installing a water purifier in your home will provide your family with clean, delicious drinking and cooking water. After installing a reverse osmosis drinking water system, many families have discovered that the members drink more water and consume fewer sodas and other sugary drinks.
  • Investing in a good water purifier is convenient in many ways, as you don't have to buy bottled water, fill up water containers outside the grocery store, or spend on the water delivery service. For a lower cost, reverse osmosis filtration can provide clean, filtered water. Pureit RO systems start from as low as Rs. 10000 and this way you can buy an advanced and ideal water filter that can be used for a longer period of time.
  • Reverse osmosis is divided into seven steps, each of which intensifies the process. You get to pick how many steps you want as per your preferences. All systems are built differently, and the water passes through seven stages of filtration, , making it a time-consuming process.These jobs will subject the water to a more rigorous treatment in order to filter it as thoroughly as feasible.
