RO purification is the most effective way to get rid of all the impurities in the drinking water that cause a good deal of harmful water-borne diseases.

We consider RO purification as the best purification process for eliminating the most deadly impurities from the drinking water that are heavy metals and dissolved salts.

Quality of Water at Your Home

The hardness of the water decides what type of water purifier you need for your home. Many water purifier brands provide water test/ water purifier demo. You can apply online for the water test by visiting their website and filling in the required details in the demo forms. The technician will visit your place to conduct a water test.

Quality of the RO Membrane

RO membrane is the most important part of the RO water purifiers as it defines what type of impurities it can remove. The pore size of the membrane plays a vital role in filtering out the impurities. RO membrane has a pore size range of 0.0001–0.001 microns. This pore size shows it is the only membrane that can filter out metallic ions and salts from the drinking water such as lead, arsenic, mercury, iron, fluoride.

What are the other filters used in RO Purifier?

Other than the RO membrane there are other filters available in an RO water purifier. Every filter relates to a particular stage of purification and is used to remove different impurities in the water. There are also pre-filters used in RO water purifiers before RO membrane that helps in maintaining the life of the RO membrane such as sediments filters and carbons filters. The role of these filters is to remove the chlorine and other sediments that may be clogged in the RO membrane and can reduce the life of the RO membrane. In an RO water purifier, the combination of different water purification technologies is used such as RO+UV and RO+UV/UF to ensure that the water is free from every impurity.

UV Purification is used to kill all the harmful bacteria, germs, and other micro-organisms. Make sure the UV lamp used in the RO water purifier is of high intensity. A high-powered UV lamp ensures the complete deactivation of all microorganisms. An 11 Watt UV lamp is very much capable of killing all the deadly organisms in the water. UF process is for double purification of the water. There are also post-carbon filters used in water purifiers to give final purification to the water.

Does purified water have minerals?

One of the biggest disadvantages of the RO process is the removal of essential minerals during the RO process. The traces of these minerals are required of your body in order to stay healthy. Since the pore size of the RO membrane is so small that only pure water can pass through it. Due to slightly bigger, the minerals cannot pass through the membrane along with pure water. When you are planning for an RO water purifier, make sure the water purifier you choose has some technology to keep those minerals in the water. TDS controller is a device that is used for maintaining the traces of those minerals in the drinking water. Kent RO water purifier is the best water purifier in India as it gives 100% pure drinking water along with the required amount of minerals in it.

Maintenance and Service of the RO water purifier

All the RO water purifiers require maintenance to function properly and delivers purified water all the time. All the filters used in the RO water purifier need to be replaced after 5-6 months. To ensure you never feel trouble for the servicing of the RO water purifier you choose, you must know about the service network and after-sales service of the company. Many of the customers have faced many problems at the time of the servicing of the water purifier. Good customer support and service is one of the important qualities that make the brand a leader in the market.

Is the water purifier company certified?

You should not believe easily what the sales representative said about their product as no company will claim that their product is inferior to others. Every water purifier company claims that they offer the best purified and safe drinking water in the market, therefore, it became difficult to choose the best RO water purifier. It is the certifications honored by the water purifier brands that make it authentic. So, always choose the water purifier that renowned laboratories of the world have certified. NSF, WQA, ISI, and CE are some of the best certifications given to any water purifier.

Storage Capacity

Looking for storage capacity is also important as it will tell you about how much water an RO can store. This becomes important in such areas where power cut is always an issue. For a small family, a water storage capacity of 8-9 liters will be enough as the water will be continuously refilled as purification starts.

Ease of operations of RO

Drinking water is the most important and easiest way to stay healthy and for purifying water it should also be simple and easy to use. So that you don’t have to struggle for getting a glass of pure water. Choose the RO water purifier that requires almost no manual intervention. There are RO water purifiers available in the market that comes with auto start and auto-on functions that mean the machine will detect when there is a need to do the purification process and stops automatically if not required. Since filters need to replace after a particular period (5-6 months), the RO must have a filter change indicator or alarm to make you aware of its filter replacement. We must equip an RO water purifier that uses UV purification with UV failure/error indicators or alarms that require your attention to replace it or rectifying the error in it.
