"If there is a third world war, it must be for water." The words of "Indian sailor" Rajendra Singh (Rajendra Singh) are still applicable in this day and age. Access to clean drinking water has always been a recurring problem, and the situation does not seem to improve. The government promised to provide tap water to all households in the next few years, but even so, the quality of drinking water has always been a serious problem.

No wonder the population of most large cities is increasingly dependent on water purifiers. According to a 2019 report from the National Bureau of Statistics, a quarter of urban households rely on water purifiers. However, some choose cheaper options, but they may not be 100% effective.

Finding the right water purifier is the key to ensuring you drink clean drinking water.

So, what factors should be kept in mind when choosing a water purifier? It's time to find out.

1. Test the water quality at home: Before choosing a water purifier, be sure to test the water quality at home. According to World Health Organization guidelines, total dissolved solids (TDS) in water include calcium, magnesium, potassium, sodium bicarbonate, chloride, and sulfate. In most cases, the water purifier can basically remove all the pollutants in the drinking water, but may leave some pollutants. Therefore, before installing the water purifier, be sure to check the water quality. In addition, please check whether the water purifier has NSF certification. In India, when there are no other sources available, a maximum of 500 milligrams per liter (MG/L) is considered acceptable, while 2000 mg per liter (MG/L) is acceptable.

Also, smell the water and check the taste and color to see if there are any visible particles. Depending on the types of impurities present, you can choose UV-C or RO water purifiers.

2. Use UV-C treated water: It is important to understand that healthy drinking water does not contain toxic and harmful chemicals, and contains minerals required by the human body. UV-C water purification ensures all this and more. It is safe and healthy because UV-C technology can eliminate up to 99.99% of microorganisms such as bacteria and viruses. In addition, it does not cause changes in the taste or smell of the water consumed.

3. Stainless steel water tank: Some water purifiers also provide the option of choosing stainless steel water tank. People may think that steel is safer than plastic, but once the water is purified and stored, it can be consumed. So, you can choose whatever you want.

4. Consider the cost of replacing the filter: The water purifier is responsible for the heavy work of filtering contaminants from drinking water. The filter element is composed of a filter medium, namely activated carbon, which will block for a period of time. To ensure the efficiency of the purifier, you must replace the filter in accordance with the instructions provided by the manufacturer. The cost of the filter varies according to the type and model of the water purifier. Before choosing a purifier, make sure you also have important information about replacement and repair costs.

5. Consider the amount of water your family drinks: Don’t we always consider the number of people in our family when we buy a car? The same applies to water purifiers. Since water purifiers have storage capacity, it is necessary to consider the amount of clean water they can deliver in the event of a power failure. It should be enough for your family. A large family may like to choose a countertop purifier.

6. Maintenance is the key: Maintaining the water purifier is an equally important job. Since the purifier removes several different types and sizes of impurities, the filter must be cleaned and maintained in order to continue to obtain clean water. But there is more to be aware of.

Most water purifiers are equipped with UV-C tubes. It is important to ensure that the UV-C tube is working properly. This is something that needs to be checked by a professional who comes to repair your water purifier.

Another problem with substandard (and possibly cheap) purifiers is that they may contain counterfeit UV-C tubes. Therefore, please pay attention to ensure that the UV-C tube in the water purifier is authentic. Please note that all blue light tubes are not UV-C tubes, and they may not be suitable for purifying water.

Although there are various brands to choose from today, it is important to choose a company that provides both credibility and security. Osram ticked all the correct boxes. Osram UV-C tubes have been globally recognized and supplied to most water purifier brands in India, which means that safe drinking water will never be a problem.

All in all, if it is about safe drinking water, the UV-C tube in the water purifier must come from a genuine brand like Osram.
