Deionized water is free of any ions that naturally leach into water from the soil, pipes, and pollution. A water deionizer will run tap water through a negative and a positively charged resin filter. These resin filters are full of beads that will attract the ions of positive and negatively charged molecule contaminants. Reverse Osmosis is a filtration process that pressurizes water and pushes it through a extremely fine filter. The filter will block out a wide selection of molecules including pollutants and organisms that are harmful to your health.
A water softener is a salt or potassium based ion exchange system that removed hard minerals. A soft water system can be used to filter out the basic and large minerals that are found in water. Water filters are similar to reverse osmosis systems but have larger pores that allow water to move through with less pressure. Water filters are made to remove harmful viruses and organisms from a water source. Water filters are used to purify spring water and other sources that are intended to have a high mineral content.
Bottled spring water is said to have many benefits for your health and usually filtered rather than put through intensive purification processes. Water quality is measured as a ratio of soluble minerals and other chemicals to the water. If you home is on a public water distribution system you should learn more about how to read a water quality report. You can inspect the quality of water yourself with some test kits available at hardware stores. You should practice caution with some water quality tests because often the tests are not accurate.
Our water quality test will cover basic quality factors that will help you determine if your water is safe and the testing of your tap water to determine which system would be best for you.

For instance, boiler water will need to be treated if too many impurities are found in the water. High amounts of impurities can lead to development of scale and a worsening of system efficiency, which is why many industrial facilities are required to treat their water on a regular basis.
Understanding the differences between the various types of water should help you identify which option is best for you or the specific application that the water is being used for. The following offers a closer look at the primary differences between purified water and distilled water.
Both purified water and distilled water have their own benefits, which is why you might want to know how they differ from one another. Purified water is a kind of water that has been effectively filtered with the goal of removing various impurities from the water.
The many impurities and contaminants that are removed from water during the purification process include:. While these four processes differ significantly in how they purify water, they are able to provide similar results. In order for water to be classified as purified water, it must have lower than 10 PPM, which means that around 99 percent of all contaminants must be removed from the water.
Purified water is considered to be the healthiest type of water , which is why it comes with many notable health benefits. While the EPA has set guidelines that require public drinking water to be rid of at least 90 percent of contaminants, different states have their own guidelines. Even though state guidelines for public drinking water must be at or higher than the 90 percent removal rate for contaminants, some states have stricter regulations than others.
Drinking water that has been purified from 99 percent of contaminants is always going to be healthier than drinking water that still contains up to 10 percent contaminants. Ultra pure water contains no electrolytes, which your body needs.
A deficiency in electrolytes can lead to high blood pressure and other health problems. There are some issues with purified water that you should be aware of before you drink it. In most Western countries, public drinking water is purified to make water safe for human consumption. However, standards for drinking water around the world vary and are typically based on governmental regulations or international standards. In fact, the World Health Organization estimates that over 2.
In countries that purify public drinking water, various treatment methods are used to make water safe, including 3 :. For example, the US Environmental Protection Agency EPA sets legal limits that are considered safe for consumers for over 90 contaminants in drinking water 4.
Although measures are taken to ensure that public drinking water is safe for consumption, it can contain trace amounts of contaminants that could negatively impact health. For instance, the heavy metals lead and copper are extremely toxic to health. They can cause stomach distress and lead to brain damage when ingested over time 6 , 7. These heavy metals have been known to leach into drinking water, even in countries where public water sources are closely regulated 8. By using in-home water filters or drinking purified bottled water, drinking water undergoes another level of purification that can remove metals, chemicals and other contaminants, depending on the type of purification system used.
Water purification systems like charcoal filters remove chlorine, a common chemical added to the public water supply as a disinfectant. Several studies have linked chlorinated water to an increased risk of certain cancers, including colorectal cancer 9 , Another benefit of water purification is that it removes unpleasant tastes associated with chemical treatments, organic matter or metal plumbing, leaving you with fresh, pure-tasting drinking water.
For example, fluoride is a mineral that is added to public drinking water supplies in some countries to improve dental health and reduce dental decay Although this practice has led to decreased tooth decay in children, especially in at-risk areas, some argue that fluoridated water is not worth the potential health risks associated with its use.
Excessive fluoride levels can be toxic to both brain and nerve cells, and long-term exposure to high levels of fluoride has been linked to learning, memory and cognitive deficits However, experts argue that the level of fluoride found in drinking water is safe and beneficial in reducing tooth decay, especially in children who are only exposed to fluoride through drinking water Research on the safety and efficacy of fluoridated water is ongoing, but those who drink purified water should be aware that some purification systems remove fluoride from drinking water.
Distillation involves boiling water and collecting the steam, which returns to water upon cooling. This process is very effective at removing contaminants like bacteria, viruses, protozoa like giardia and chemicals like lead and sulfate Due to the fact that distilled water is exceptionally pure, it is commonly used in medical facilities and laboratories.
Though drinking distilled water is not as common as drinking other types of purified water, some people choose to drink it because it is free of contaminants. Levels of pesticides and other chemicals in public water sources like tap water will depend on your geographic location and the agencies that regulate drinking water safety in your country. Distilled water is essentially free of contaminants like pesticides and bacteria, which could be especially helpful to those with weakened immune systems.
The distillation process is very effective at removing potentially harmful contaminants, but it also removes the natural minerals and electrolytes found in water.
Along with unwanted impurities, beneficial minerals like calcium and magnesium are also left behind as the steam rises during the distillation process. In fact, distillation typically removes around Though water is not typically thought of as a source of minerals, any factor that leads to a decreased intake of essential micronutrients could negatively impact your health. Like other methods of purification, distillation removes fluoride from drinking water, which may put those who choose to drink distilled water at an increased risk of cavities.
In most cases, public drinking water sources like tap water are safe due to the strict contaminant limits set by regulatory agencies. However, drinking water can become contaminated from natural sources or human activity, affecting water quality For this reason, it may be a good idea to invest in an in-home water purification system, especially those who are immunocompromised and more susceptible to becoming ill from contaminated water.
In countries where water contamination is an issue, especially in developing countries with lack of proper sanitation, choosing bottled or purified water is always the safest option.
Many types of purification systems are available, including charcoal and UV filters, which remove impurities that may survive the initial, large-scale purification process that most tap water goes through. That being said, in countries where public drinking water is regulated for quality and safety, drinking tap water is relatively safe. If you question the quality of your tap water, you can test the water by purchasing a home test kit or contacting a water testing agency in your area.
Most public sources of drinking water are regulated for safety, but some people choose to use home water purifiers to further improve water quality. Household water treatment units can improve the taste or odor of tap water and remove specific contaminants.
