Low access to drinking water, along with inadequate sanitation and hygiene conditions, are the leading causes of waterborne diseases, which produce approximately 1.8 million deaths annually worldwide.
The supply of clean water through centralized systems is a difficult task in developing countries. These large-scale systems involve massive operation and maintenance efforts.
And there is always the risk of re-contamination of drinking water during the distribution, and management processes in the place of consumption (homes, schools, offices etc.).
Therefore, water treatment at the domestic level through the use of simple and useful options can significantly reduce the incidence of waterborne diseases.

Let’s see a quick review:
Ninety percent of the world’s water supply is not suitable for drinking without some treatment. Polluted water is hazardous to health.
So there are water purification systems that kill these harmful microorganisms so that you can drink clean water.
The water can be purified by boiling, chemical treatment with chlorine, or iodine, or acquiring the best water purifier for home.
Due to the presence of pathogens such as bacteria, and protozoa, and toxic substances such as heavy metals, contaminated water is capable of endangering the health of the population.
This water should not be used for human consumption, or even for recreational purposes.
Why is water purifier necessary?
- Among the significant diseases triggered by contaminated water, diarrhea is the most prominent.
- Every year, millions of people, mainly children, die as a result of this disease caused by the consumption of water unfit for use.
- The highest number of deaths is among low-income people, often because of poor basic sanitation.
- In addition to diarrhea, other diseases that can be transmitted by contaminated water are giardiasis, leptospirosis, cholera and typhoid fever.
- A large number of deaths could be avoided with efficient sanitation projects. Greater scrutiny must be carried out about chemical disposal, fertilizer use and sewage treatment before it introduced into rivers.
- It is also essential that water is treated and tested before it is sent to the population.
- You must test the water purifier with a TDS meter before buying it.
Note: During the purifying process of the best water purifier, around 650 ml of water is wasted for every 1litre of purified water.
So it is suggested to store that wastewater in utensils or buckets so that you can use that water for washing clothes, utensils, cleaning the house, and many more things to save the water.
Acceptable TDS Levels:
- Below 300 – Water is excellent for the consumption.
- Between 300 to 600 – Water is suitable for consumption.
- Between 600 to 900 – Water is fair and is acceptable for consumption.
- Between 900 to 1200 – Water is inadequate and unacceptable.
- Above 1200 – Water is unfit for consumption.
Technologies used for water purification:
RO (Reverse Osmosis):
It is the process by which water is forced to pass through a semi-permeable membrane, preventing certain elements contained in the water from moving, such as viruses, bacteria, sediments, chemicals, salts, minerals, and heavy metals.
This membrane has many pores of tiny size.
This filter removes all the large impurities and dust particles from the water. It is used only in places where the water contains a lot of pollutants.
Pre-Activated carbon filters:
It removes the organic particles from the water, which are responsible for the bad odor of the water.
Revise Osmosis Mechanism:
In this process, the water is passed from the semi-permeable membrane. As the water cannot move from low concentration to high concentration, a motor is used.
After that, the water is divided into two parts; the dirty water is sent down to the drainage, and the clean water is sent for the next step of its treatment.
In this chamber, the water in the RO filter is filtered. Again as it contains the viruses and some other contents in it as the membrane cannot separate the particles which have the molecular mass less than 20.
So the water is treated with the ultraviolet rays, and all the viruses and the bacteria are killed. The water is made 100% pure after this step is completed.
Under this process, the water is passed through the membrane, and all the residual particles that are still left in the water are removed out as this membrane has minute pores, and all the left particles are separated.
Post-Activated Carbon Filter:
This process removes all the organic particles that cause the smell and improves the taste of the water.
When the water is passed through the RO, it separates all the minerals from the water; even it removes the calcium and many more minerals, which are essential for the growth of the body.
So the TDS controller separates the input water into the two parts A and B.
A part is passed through the RO process, and part B is passed through the UV/UF, so part B contains the necessary minerals, and after that, both the parts are mixed with increasing the pH value of the water, and it makes the water healthy to consume.
This improves the quantity of the minerals in the water as the part of water passed from the RO process is the lack of minerals, so due to this, it is necessary to add the minerals back.
Mineraliser adds the removed minerals back to the water and makes it healthy to consume as now it contains all the essential minerals that are essentials for the growth of the body.
Active Carbon Filter: It will efficiently remove the organic chemicals and pesticides from water, thereby making it safe for the whole family to drink.
If the water in your zone is hard, then you need to get the purifier that comes with this technology.
Other characteristics you should look for when buying a water purifier
- Not Time Consuming: You need to make sure that it purifies the water in little to no time.
- Budget-Friendly: Buy one that is cost-efficient and provides the best services while being within the limits of your budget.
- User-friendly: You need to choose one that is easily operated and work with.
- Best Reviews: You can also check the reviews of the people who are already using the water purifier.
The price and quality of reverse osmosis:
Before entering the subject, it is essential to let you know the importance of the variety of this equipment. There are a few companies that offer water purification with RO facility but, their low price reflects on their abilities.
If your central premise is to save money, choose equipment that balances its price by offering quality.
These low prices are not only based on inferior product quality, but they are also based on the absence of accessories, and the quality of them.
The membrane also suffers from this loss of quality and affects us directly. We must not forget that the right or lousy purification of the water depends on it.
We cannot take any risk to save a few dollars. It is better to opt for a genuine quality RO purifier than drinking the unhealthy water every day. This is killing us every day little by little.
When is the use of reverse osmosis recommended?
The main reason that recommends its use is the removal of excess lime and other salt particles that are dissolved in the water. It makes the water clean, healthy, and risk-free.
The high purification power of the Best water purifier ro makes it ideal for purifying waters that may contain traces of harmful substances, both organic and chemical.
Things To Consider Before Buying Water Purifier
Of course, it is also used when you want to consume the purest water possible, regardless of the quality of the incoming water. The best option will be to choose the RO+UV water filter.
This will give you double benefits – clean water, and healthy water, 200%.
