Water is essential to all life. A healthy body needs healthy water. There is a seemingly endless debate going on about the water that we drink. Spring water, mineral water, ionized water, there’s no shortage of water products that are being marketed as the essence to good health. Some of it is true, some is pure exaggeration.
Regardless of what marketeers want us to believe, it is common knowledge that tap water can contain any number of unwanted contaminants. Whether it’s harmful chemicals or metals, there is a genuine concern that the water supplied to our homes may not be all that healthy. It’s little wonder then that water filters and purifiers have become so popular. Most of us have considered the pros and cons of purifying the water supply to our homes.
As we begin researching water filtration systems, purifiers, deionizers, and water distillers, things seem to become way more complicated than we first thought. This article should help you gain some clarity on the matter. There are many questions that people want answered about water purity and its effect on our health. This topic is but one of them, the difference between distilled water and purified water.
You may also want to do more research, like the difference between a water filter and a water purifier, but it’s a good idea to start by looking at a water purifier vs water distiller.
By boiling water and then condensing it, the water is distilled. The processing involves extracting pure H₂0 in the form of water vapor which is a gas. By cooling the gas, it reverts back to a liquid, water that we can drink.
The science behind water distillation is the different boiling points for various elements. Water boils at 212°F (100°C) when at sea level. At higher altitudes, water will boil at a slightly lower temperature, because of the decrease in air pressure. Though, for most practical purposes, the boiling point at sea level is the accepted temperature. In the end, the relative boiling point of other elements in the water will also evaporate at a lower temperature when the atmospheric pressure is reduce. The relative effect remains the same.
Metals will boil at a much higher temperature than water. This means that as the water is converted into a gas (at approximately 212°), the metals in the water remain in a solid form and will separated from the water. Other elements, that evaporate at less than 212°, will convert into gas before the water boils. This means that some contaminants in the water, which may include pesticides and volatile organic compounds (VOCs), will evaporate with the water, and will condense when cooled.
Distilled water may still contain some harmful contaminants. Most bacteria cannot survive the high temperature of boiling water, so it is generally considered safe. However, the water will not be completely pure. Additional purification may be required to remove some elements that remain after the water has been distilled.
Generally, distilled water is used when metals can be harmful or affect the outcome of a particular reaction. Distilled water is common in laboratories and industrial applications where metals are not desirable. It is also used for water cooling systems.
Is Distilled Water Safe to Drink?
Yes, distilled water is perfectly safe for us and our pets. It will be free of bacteria but may contain some contaminants that are not entirely healthy, but still safe for consumption.
Because water distillation removes metals, some healthy minerals will also be removed. We generally consume these minerals as part of a healthy diet, or by taking mineral supplements, so distilled has little effect on the minerals that we need.
Water Distiller vs Water Purifier
Having identified the difference between distilled and purified water, you will want to decide which system will work best for you. There are pros and cons to using either a water distiller or water purifier. The latter being a more advanced RO water filtration and purification system.
A water distiller is not expensive to buy but does use quite a lot of electricity. While distilled water is not 100% purified, it is safe to drink and will not contain any hazardous metals. However, by removing minerals from the water, it loses most of its taste.
The greatest advantage of using a water distiller is that the water is good for appliances that can be harmed by metals in the water and for other practical uses, like cooling systems and batteries.
While RO water purifiers are the most expensive, they are generally considered the best way to provide pure filtered water to your home. They are convenient to use, as purified water is supplied directly to a faucet or the whole house. You are able to utilize multiple stages to improve quality, taste, and good health of the water in your home. A whole house RO water purifier will also protect pipes and fixtures.
