Can water purifiers remove fluoride? Yes, water purifiers can remove excessive fluoride from water. To remove harmful substances from the water like arsenic and fluoride, you need an electric water purifier with an advanced RO purification system. Water purifiers with regular RO purification systems would not be able to do such hard purification.

During multi-stage hard purification, water loses its natural properties, vital elements, and essential minerals. Drinking water without its natural value in it — is not going to benefit health-wise. Therefore, a water purifier, which removes the harmful substance from the water should also have the technology to correct its pH value and revitalize it with essential minerals.

Can water purifiers purify salt water?  Do water purifiers remove salt from the water? The answer is YES. In Chennai city, the corporation runs many large RO purification plants to purify seawater.

To purify salty water, you need a water purifier with an RO and UV purification system at least. After passing through a robust RO purification system, salty water becomes natural water. However, it is still not free from germs and harmful bacteria. To make it safe for drinking, the water next has to pass through a UV chamber. After UV purification water becomes safe for drinking. To make the water 100% safe for drinking, your water purifier must also have a UF membrane as the last stage purifier.

In this piece, we cover high-end water purifiers, which are capable of purifying not just regular hard water, but hard water with harmful chemical substances. Here you read about the best water purifiers from 15000 to 20000 Rupees price range in the Indian market.
