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.
Enjoy Mineral RO Water With 8-Stage Filtration
The 6-in-1 composite filter D4RF uses the least space to achieve an optimized filtration effect, reducing TDS, chlorine, chloramine, heavy metals and more. We protect drinking water safety for your family from the source. Waterdrop remineralization filter MNR35 adds 18 natural minerals in to water, including calcium, magnesium, sodium, potassium. You will benefit from RO mineral water in the long run.
Add Minerals To Make A More Comprehensive Protection
Minerals such as calcium, magnesium, sodium and potassium are indispensable trace elements for human body. MNR35 remineralization filter add these natural minerals into water to keep health at all times.
Filtered Water Increased By 300%
1:1 drain ratio, compared with the traditional RO machines, it can filter up to 300% more purified water, make efficient use of water resources, and save your water bills.
Fast, Stable, Long-Lasting With 400 GPD
The water output is more rapid, stable and durable. It only takes 12 sec to fill glass of water, which can meet the water needs of the whole household.
Quick Replacement, Convenient Life
The intimate buzzer reminds you to replace the filter, you only need to replace it once a year with a push-and-pull, which you can easily operate it at home.
Great Upgrade With Small Size
The elegant reverse osmosis home system is only 12.44-inch in height. The design of the tankless reverse osmosis system makes its size even smaller, which helps same more space under the sink. The system can fit in most kitchen sinks.
Easy Installation Without The Help Of Plumber
It only take 30 minutes to install RO machine which you can operate easily at home. One pull and push then you can complete the filter replacement without adding additional housework burden. MNR35 remineralized filter can be directly connected to water tubing to provide mineral water at home.
*It is not recommend to use well water as the source of RO system, or connecting a tankless RO system to a refrigerator or ice maker.
It is strongly recommended to use the components provided by Waterdrop to install RO system. Installing the system with any parts or accessories not supplied by Waterdrop may cause system failure or shorten the service life of the system / filter.
