Why use a water filter instead of bottled water?

bottled water waste

The impact of bottled water on the environment is monumental, wracking up environmental harm from the moment the plastic bottle is made and filled, to the moment the used bottle is tossed in the trash. The process of making plastic water bottles sold in the United States alone uses approximately 1.5 million barrels of oil, according to the Earth Policy Institute–that’s enough to run 100,000 cars for an entire year. And that doesn’t even take into account the inordinate amount of oil needed to transport water bottles all over the world–a bottle of Fiji water enjoyed in New York City, for example, would have traveled nearly 8,000 miles from Fiji to New York.

Adding insult to injury, people consume most water bottles outside of the home, where finding a recycling bin can prove a daunting task. Nearly 80 percent of water bottles are not recycled, resulting in 38 billion water bottles clogging landfills each year where they take 700 years even to begin to decompose.

misconception about bottled water

Many people drink bottled water because they believe it to be a higher quality, cleaner, and better-tasting, but that’s not necessarily true. In fact, an estimated 25 percent or more of bottled water is really just tap water in a bottle—sometimes further treated, sometimes not.

So why are we paying for someone else to bottle our water when we could simply filter our water at home? Bottled water must just taste better, right? It would appear not. Good Morning America conducted a blind taste test of water using its studio audience as guinea pigs and guess which water source was the clear winner? New York City tap water. Yes, that’s right: Tap water beat out Poland Spring and Evian.

Okay, so tap water tastes the same as bottled water and is far less harmful to the environment but is it safe? In the U.S., public water is regulated by the Environmental Protection Agency (EPA), which requires multiple daily tests for bacteria and makes results available to the public. The Food and Drug Administration, which regulates bottled water, only requires weekly testing and does not share its findings with the EPA or the public. In 1999, after a four-year review of the bottled-water industry and its safety standards, NRDC concluded that there is no assurance that bottled water is cleaner or safer than tap.


According to an extensive study done by NRDC and taking into account federal standards to regulate bottled and tap water, there is no assurance that bottled water is cleaner or safer than tap. And many blind tests show that bottled water doesn't necessarily taste better than tap. 

Unless you live in a rural community with a higher likelihood of pesticide runoff contamination, or if you get your water from a private (unregulated) well, or live in an old home (built before 1986) with possible lead contamination from aging pipes, using a water filter is a smarter choice in terms of cost and the impact on the environment.

Getting started

Read your municipal water quality report

You should first check with your municipal water service company for a Annual Water Quality Report, also known as a Consumer Confidence Report to figure out what's in your water. You also can test your water yourself. Standard consumer test packages are available through large commercial labs at a relatively reasonable price. Then you could figure out what contaminants should be filtered through your water filter system.

Look for NSF certified filters

You should purchase filters certified by NSF International. These models are designed to filter out specific contaminants, so you can select one based on your needs. When you see “NSF Standard 42,” it means that the filter passes for “aesthetic effects,” like removing chlorine, which makes water taste and smell better. If you’re more focused on the health effects of filtration, look for a product that passes “NSF Standard 53,” which evaluates a list of dangerous impurities, like lead and giardia. If a filter is “NSF Standard 401-certified,” it has been shown to remove trace amounts of prescription drugs and pesticides.

Water filter types

Asset 14.png


> Inexpensive
> No installation required

> The least effective in filtering

Asset 15.png

Faucet-Mounted: Carbon Block

> Inexpensive
> Easy to install

> Could be bulky when washing dishes with the filter attached to the faucet
> Not as effective in filtering as under-sink systems


Asset 16.png

Under-Sink: Carbon Block

> Most effective in filtering
> Keeps essential minerals in water

> More expensive than pitcher or faucet-mounted systems
> Harder to install than faucet-mounted systems

Under-Sink: Reverse-Osmosis

> Most effective in filtering

> Removes essential minerals from water
> More expensive than pitcher or faucet-mounted systems
> Harder to install than faucet-mounted systems
> Waste of several gallons of water for every gallon filtered


Pitcher water filters are the cheapest but the least effective in removing contaminants. Reverse-Osmosis water filters are the most efficien in filtering but remove essential minerals, which is critical for your body's health. (Please check out this article on what constitutes a healthy water: Analyzing & comparing brands of bottled water)  So we recommend carbon block water filters which maintain essential minerals or Reverse-Osmosis filters with remineralizing filters.

Climate change's threat to penguins

In Antarctica, home to the famous emperor penguin, the annual sea ice melting season has extended by as much as 3 weeks in recent decades. Less ice means less habitat for penguins and the loss of critical food, such as shrimp-like krill, which depend on polar ice to reproduce.

The penguin that is currently most threatened by climate change is the African penguin. Most African penguins live on islands off the coast of Africa and feed on a rich supply of anchovies and sardines that follow a nearby current of cold water. As the oceans heat up, this stream is moving further away from their island home. These penguins will only swim up to 25 miles away from their homes, so if the current moves much further they will not be able to reach their food source.
