What is mineral water?
Mineral water commonly contains substances like magnesium, calcium, sodium, and zinc, and, according to recent research, they’re actually a pretty effective way to boost your mineral intake. A recent study found that mineral water has some legitimate health benefits.
At its core, mineral water provides minerals the human body can’t create itself. While you don’t need to drink bottled water to get your magnesium RDA, those pricey bottles are a legitimate method of consumption. In addition to promoting healthy bone development, the study also notes “significant benefits for healthy digestion” thanks to magnesium sulphate, sodium sulphate, bicarbonate, and chloride.
The benefits of drinking mineral water
Bone enhancer
Improve bone health and help prevent diseases such as reducing post-menopausal bone density. It also maintains muscle performance with its magnesium content.
Lowering bad cholesterol
Bad cholesterol increases your risk of heart disease and heart attacks.Scientific studies reveal that mineral water lowers harmful cholesterol due to its magnesium and potassium content.
Promotes digestion
Help digestion by increasing the amylase secretion from the pancreas with its sulfate content
Beautiful sink
Mineral water, with its rich mineral content, also contributes significantly to maintaining skin health. It moisturizes the skin and delays wrinkles.

How to remineralize reverse osmosis water?

The Waterdrop reverse osmosis (RO) process describes how the filter filters the water. Osmosis is a natural process involving the transfer of a solvent from a low concentration to a high concentration region through a permeable membrane. Conversely, reverse osmosis uses hydrostatic pressure to push the solvent molecules from a high concentration region to a low concentration region.

How does a remineralization filter work?

If the filter offers more filtration stages, it will include a post-activated carbon filter or a remineralization filter. Water passes through either of these, and minerals are re-added into the water, ensuring a balanced pH level.

How often should remineralization filter change?

You can get up to one year of service life out of a remineralization filter. The system will notify you when it is time to replace the filter through the filter life indicators on the panel.

What does reverse osmosis remove?

The Waterdrop reverse osmosis filter can effectively remove up to 99% of contaminants present in water, including chlorine and fluorine, cadmium, barium, radium, chromium, arsenic, lead, and other heavy metals. It also removes sulfates, nitrates, rust, sediments, dirt, and others. In addition, it is effective against total dissolved solids (TDS), herbicides, pesticides, volatile organic compounds (VOCs), and parasites.

How to change reverse osmosis filters?

The instruction manual that comes with the product contains a step-by-step installation guide to help you remove and replace the remineralization filter. You can also check out the Waterdrop YouTube channel for an explainer video.

What is remineralization reverse osmosis system?

The reverse osmosis water filter with remineralization comprises a remineralization filter and a RO system. The latter removes impurities from the water, while the former adds essential minerals like calcium, magnesium, potassium, sodium, and others to the purified water.

How to add minerals to reverse osmosis water?

The PPC technology in the remineralization filter activates the crystalline structure of the minerals, thereby stimulating the mineral spring formation and activation of every mineral present.

What is reverse osmosis water?

When a Waterdrop tankless reverse osmosis system removes the majority of contaminants in water by pushing it through a semi-permeable membrane under high pressure, the purified water is called reverse osmosis water.
