How does bottled water get filtered?

Most water bottlers use reverse osmosis to remove contaminants from water before bottling. In RO, water is forced through a semipermeable membrane. The membrane allows tiny water molecules to pass through it while filtering out impurities dissolved in the water. The Brita bottle filter passes water through a carbon filter element designed to remove specific substances at low pressure.

Bottle filter contains a proprietary blend of activated carbon and a binder that holds all ingredients together. The water passes through a porous filter where chlorine (taste and odor) adsorbs and decomposes on the surface of the activated carbon. More specific details can be explored on the Brita support webpage. By far the strictest regulatory body overseeing the bottled water industry is the industry itself, especially in the form of the International Bottled Water Association (IBWA).

The IBWA enforces the voluntary self-regulation of its members, who produce about 80 percent of bottled water purchased in the United States. IBWA members must comply with the requirements set out in the IBWA Model Code, which includes disinfection in the form of reverse osmosis, filtration or distillation for any water extracted from a municipal drinking water source. Companies that use protected natural sources are not required to disinfect water. An independent group that evaluates the quality and compliance of bottled water is the National Sanitation Foundation (NSF), which runs a voluntary Bottled Water Certification Program that includes inspecting the water source and plant and testing water (for contaminants) and sealing processes containers.

See the NSF list of products and services for a list of NSF certified bottled water. There are many reasons to choose filtered water over bottled water. The most obvious reason is convenience. A quality water filter can easily remove unwanted and harmful contaminants from tap water without having to go to the store to buy bottled water.

Simply fill a refillable water bottle and you'll always have clean water to take with you on the go. Is bottled water leaked? Sometimes it is. If the water comes from groundwater or a municipal water supply, it is purified before being bottled. If the water is natural spring water or mineral water, it may not be filtered before delivery, as some types of filtration, such as reverse osmosis, could remove beneficial minerals.

For the average family who drinks the suggested amount of water per day, the cost of bottled water can increase quite quickly. The results showed no difference, in terms of unhealthy contaminants, between bottled water and tap water. If you heat a water bottle that contains phthalates, the bottle could leak some of those chemicals into the water. Of course, in parts of the world where drinking water is not readily available, bottled water is an excellent option despite any environmental concerns.

The FDA and EPA use similar standards to ensure safety, which means that the standards set for tap water are similar to the standards for bottled water. Drinking plenty of water is crucial because water not only regulates the body's internal temperature, but it also prevents infections, keeps organs working properly, and keeps cells healthy. Many bottled water drinkers report that taste is the main reason for their bias: they just think bottled water tastes better than tap water, end of story. If you have a hand-filtered water bottle, you can drink from that stream without worrying about getting sick.

But a couple of blind, very unscientific taste tests have found that most people, or most people in New York City, to be more precise, can't differentiate between tap water and bottled water once they're all placed in identical containers. Tap water may not be perfectly clear or may have a slight chlorine aftertaste, but according to the Minnesota Department of Health, those are purely aesthetic qualities that do not indicate that the water is unsafe. Dentists warn that this can lead to more long-term dental problems for people who only drink bottled water that does not contain any or enough fluoride (some bottled waters leave fluoride or add it as a beneficial mineral after processing). Brita mentions that only one of its filters can replace 300 disposable water bottles; the same can be said for any other bottle.

Many filters are designed to remove contaminants such as chlorine, chloramine, lead, and other bacteria that can cause water to smell and taste bad. . .
