Water plays such an important role in ensuring that we are healthy and feel great. Many people leading healthy lifestyles have turned to various filters in order to ensure that their H2O tastes great and is free of contaminants. There are many different filtration options on the market, and many are an economical and convenient way to enjoy drinking water that tastes great.
What is a water filter?
Water filters purge or at least reduce impurities found in water. Water filtration is used for many different purposes, including creating an ideal environment for aquatic animals and eliminating impurities from liquids used to cool electronics. Filters are also used to make water drinkable. Water filtration systems are used throughout the U.S. to deliver clean drinking water to homes and businesses, and many people opt for in-home filters and portable filters not only to improve taste but to ensure that it meets their standards.
Are water filters certified and what types are available?
Many filters are certified as well as rated based on their abilities to remove bacterium, reduce contaminants, and so forth. The organizations that are accredited by the American National Standards Institute to evaluate and certify filters and filter systems are:
- NSF International
- Underwriters Laboratories
- Water Quality Association
The filters available for personal use range from portable to fixed solutions. These include:
- Faucet filters
- Whole-home units
- Refrigerator water filtration
- Under-the-sink water filtration systems
- Container filtration, such as filtered water bottles
What filtering techniques are used?
There are many different types of filtration options, and these can be employed alone or consecutively via layers. Common methods for drinking water include:
- Charcoal or activated carbon, which is used in faucets, coffee machines, and containers.
- Gravel is used to trap large solids.
- Reverse osmosis eliminates bacterium, protozoa, viruses, and chemicals.
- Ultraviolet systems disinfect water effectively but can’t remove chemicals.
- Softeners eliminate hardness, such as calcium and magnesium, and can remove metals.
Do water filters extract minerals?
Some filters do eliminate or reduce minerals from water. Charcoal, which is commonly used to purge bad tastes and odors as well as chemicals, does not. Reverse osmosis and other advanced methods can. Filtered water for human consumption should retain essential minerals. Minerals from your faucet water aren’t your primary source of minerals daily but aren’t insignificant either. Note that most filters for drinking water are purposefully designed not to extract nutrients.
How often should the media be replaced?
There is no one right answer as to how often you need to change it depends on the system. For refrigerator units, manufacturers often recommend replacement every three months. The major brands recommend replacement every two months for bottles, pitchers, and other containers. Water filtration system effectiveness is usually based on volume, however, so frequent use can shorten replacement time. It’s best to follow the instructions given with the specific water filter you purchase.
