Does an RO Water Filter Reduce the Hardness of Water?
Water hardness is a term that describes the level of dissolved minerals in the water, mainly calcium and magnesium. These minerals originate from the soil and rocks that water comes into contact with, as it travels to underground aquifers, wells, and other sources. Hard water can cause issues such as soap scum, mineral deposits, and reduced effectiveness of soaps and detergents. In addition, hard water can damage appliances, such as water heaters and piping systems, over time.
How is the hardness of water measured?
The hardness of water is measured in grains per gallon (gpg), parts per million (ppm), or milligrams per litre (mg/L). Water with a hardness level of less than 1 gpg is considered soft, while water with a 7 gpg or higher is considered hard water.
TDS, or total dissolved solids, is another measurement used to describe the level of dissolved minerals in the water. TDS is a measurement of all the dissolved minerals, including calcium and magnesium, and other minerals, such as iron, copper, and zinc. TDS in water is measured in ppm or mg/L.
Why is hard water not beneficial for consumption?
Hard water can cause mineral deposits to form in pipes, giving the water an off-flavour or odour. Some studies have suggested that long-term consumption of hard water may increase the risk of certain health conditions, such as cardiovascular disease, due to the minerals present in the water. However, the evidence is unclear, and more research is needed to confirm any potential health risks associated with drinking hard water.
Overall, while water hardness is not considered harmful to human health in most cases, it may negatively impact the taste and quality of drinking water.
How different is TDS from water hardness?
While water hardness and TDS describe the level of dissolved minerals in the water, they are not the same. Water hardness refers explicitly to the level of calcium and magnesium in the water. In contrast, TDS refers to the total amount of dissolved minerals in the water, including calcium, magnesium, and other minerals.
In this situation, the best solution will be Pureit Ultima Eco Mineral RO+UV+MF Water Purifier. The Digital Purity Indicator in this water purifier detects water quality up to 5000 times per second, indicating the purity of your water is. TDS in and TDS out levels for your drinking water are displayed. This way, you can ensure how much TDS is there in your water and ensure you provide only safe drinking water to your family.
Reducing the hardness of water with RO water purifiers
RO water filters use a semi-permeable membrane to filter out impurities and dissolved minerals in the water. The membrane has small pores that allow water molecules to pass through but are too small for larger molecules, such as dissolved minerals, to pass through. RO water filters effectively reduce water hardness by removing up to 98% of the dissolved and unwanted minerals in the water. This can help prevent issues such as soap scum and mineral deposits in appliances and pipes. In addition, RO water filters can help prolong the life of appliances, such as water heaters, by reducing the build-up of mineral deposits.
One of the benefits of using an RO water filter to reduce water hardness is that it is a chemical-free process. Other water softening methods, such as using a water softener, typically require chemicals, such as sodium chloride or potassium chloride, to remove the dissolved minerals from the water. RO water filters do not require chemicals, making them a more environmentally friendly option. Take Pureit Marvella Eco Mineral RO+UV+MF Water Purifier, for example, this water purifier is perfectly compatible with high TDS water levels and adds the goodness of mineral essentials to your purified water.
In addition to reducing water hardness, RO water filters also effectively remove other impurities from water. The semi-permeable membrane used in RO filters can remove a wide range of impurities, including chlorine, lead, arsenic, and other contaminants. This can help provide clean, safe drinking water for you and your family.
