Water quality problems: tap water can be safely drinking after being filtered by filters
Tap water might be safer than bottled water
Many of us may have a big misunderstanding about tap water, thinking it’ s unsafe and opting to purchasing bottled water. However, a survey by the authorities shows that in 2018 most US cities’ tap water reached the standard of safe drinking water.
According to data from the Natural Resources Defense Council, about 25% of bottled water is made of tap water. Due to the relatively looser federal laws regulating bottled water manufacturers, your purchased bottled water is very likely another form of tap water.
Bottled water can cause great pollution to the environment, especially since most manufactures use disposable plastic bottles while making it. The only way to handle the bottles is to burn.
However, incineration can create harmful gases, and further pollute global natural water supply. Afraid of purchasing polluted natural water which can potentially cause serious illness, many people choose bottled water as their drinking water, which can add up plastic water bottle garbage. By repeatedly doing so, a vicious cycle forms.
Bottled water is energy- consuming
In the process of manufacturing and transporting bottled water, a number of problems can take place, such as consuming a large amount of oil to make plastic bottles and ship these products from water source to sales areas.
Meanwhile, handling plastic water bottle garbage needs a mass of energy, and over- production can cause water shortage in the water source.
Problems with tap water
In many US cities, tap water can reach the standard of safe drinking water, but after leaving water treatment plants it is often polluted by microorganism in old and rusty water supply lines, according to estimates.
In some areas, wooden water pipes are still in service, making tap water more accessible to pollution. The worst is that many water treatment plants add chlorine or fluorine to tap water to kill bacteria in it. Although the chemicals are not likely to harm your body too much, frequent intake can potentially cause serious illness.
Popular refrigerator water filters
There are three main refrigerator water filters on the market: activated carbon filter, reverse osmosis filter and ion filter. Among them, activated carbon filter is the most commonly used. Its carbon cartridge has many pores inside to absorb contaminants. It’s said that a gram of carbon can cover three volleyball courts.
Activated carbon filter is effective at removing odd odor and chlorine from water, but unable to deal with common inorganic pollutants such as arsenic, fluoride, hexavalent chromium, nitrates and perchlorates.
Refrigerator water filter is not only money-saving, but also environmentally-friendly
Activated water filter is enough to keep your drinking water safe in current tap water quality circumstance. So you can be reassured to drink filtered water by a reusable plastic bottle.
After drinking 20-30 bottles of water, you will find you have saved the costs of a reusable plastic bottle and a refrigerator water filter. Yes! Using filter is not only money- saving, but also environmentally- friendly compared with purchasing bottled water. Of course, your filter must be replaced regularly, otherwise it will lead to bacterial growth.
