There are four main alternatives to distilled water: Filtered water: This type of water has been passed through a filter or filtration process to remove some or specific impurities. While filtered water isn’t as pure as distilled water, it’s still a good option for drinking and cooking. Spring water: This type of water comes from a natural spring and is typically high in minerals such as calcium, magnesium, potassium, sodium, and fluoride which can be beneficial for overall health. Mineral water: As the name indicates, this type of water has been artificially infused with minerals. It’s a good source of minerals, but the amount of minerals in mineral water can vary depending on the source of the water. Reverse osmosis water: This type of water has been passed through a semi-permeable membrane to remove unwanted molecules and substances. It’s a good choice for people who are looking for the purest possible water, but it lacks beneficial minerals.
