If not properly maintained, contaminants can build up on old filters and seep into drinking water. Purified water is safe to drink because it can remove residual contaminants such as bacteria and metals from tap water, according to the EPA. At the same time, most purification systems will also preserve some of the beneficial minerals in tap water, such as calcium and magnesium. Filtered water is tap water that is purified to make it safe to drink.
How water is filtered depends on the type of filtration system and the brands of bottled water. This includes activated carbon filters, which are most commonly found in domestic water jug filters, reverse osmosis, distillation, and ion exchange. Filtered water at home strikes a balance between health and affordability, according to Marvin Singh, MD, gastroenterologist and founder of Precisione Clinic in San Diego. However, many water contaminants don't add flavor at all.
Singh says drinking unfiltered water isn't wise. Drinking contaminated water can cause a variety of health problems, from flu-like symptoms to hormonal imbalances, according to Dr. Lead, in particular, is dangerous for children. If you are concerned about contaminated tap water, Dr.
Singh suggests checking the water quality of your zip code on the Environmental Working Group website. If you like bottled water, Dr. Singh says it's wise to research water quality from several suppliers. Filtered water is likely to be healthier, and it's critical if you live in an area at risk of contamination, according to Dr.
Filtered water tastes cleaner and fresher than bottled water, and it removes chlorine and bacteria that can cause it to taste mild or chemical. And then, on the off chance that you drink water that isn't sterilized, it says your gut could react even more dramatically (and unpleasantly) to microbes or nitrates in the water. Distilled water is a specific type of purified water that has been boiled to remove contaminants, according to the University of Nebraska-Lincoln. You can then fill them with filtered tap water as needed, which is easier on your pocket and the environment.
If not properly maintained, old filters can accumulate contaminants and contaminate drinking water. Purifying or adding minerals to water are ways to convince customers that a product is better than its competitors, although in reality the only thing that changes in water is the taste. Because no water filtration system removes 100 percent of contaminants, there is no pure water on the market. You'll need to replace filters regularly, but the frequency and cost of a new filter will depend on the filtration system.
However, Batterman, of the University of Michigan, points out that water companies design and operate their systems to maintain a residual level of disinfectants in tap water that should prevent microbial growth or biofilms. For a Brita pitcher, that is, every 40 gallons or approximately every two months a filter is thrown away or sent to be recycled in a bicycle carrier or shower. But in general, drinking purified water is not bad for you, quite the contrary, as long as you properly maintain your filter (more on this later).
