If you have issues with water contamination, water filters and systems can provide a solution. These systems operate by screening your water and removing foreign matter that can cause disease or aesthetic issues like taste. Contaminants can enter your drinking water from runoff or through natural processes. A water filter will remove toxins, improving your water quality. You have several options depending upon your needs.
Benefits
The primary benefits of water filters and systems are to improve both the safety and the aesthetic quality of your water. Contaminants can enter drinking water systems through a myriad of sources, many of which you can't control. Moreover, water filters remove toxins which may not be visible. For example, you will not be able to detect if your water has arsenic in it because arsenic is odorless, tasteless, and colorless. Yet, arsenic can increase your risk of certain types of cancer, according the U.S. Environmental Protection Agency (EPA). Thus, a water filter or system can protect your health.
Types
You can group water filtration systems based on its location: point-of-entry devices (POE) and point-of-use devices (POU). POE examples include water softeners and filters installed after your home water meter. POU devices include systems installed under the sink, on your faucet, or as water pitchers with filters. Activated carbon filters, a POU device, will remove organic compounds and pesticides from your water. A water filtration system will remove contaminants in your water, including those which are undetectable, such as radon and arsenic.
Water Testing
A vital aspect of using a water filter system is regular water testing. If you have a known water quality issue, testing is important to make sure that your water filter is running properly. If you use a water filter system with a private well, you should test the water annually for disease-causing bacteria as part of regular well maintenance. You can also test your water if you detect any changes in its color or taste, which can indicate a health hazard. You may find that you need a different water filter system or an addition to your current system to improve water quality.
Considerations
When you consider buying a water filter system, there are several considerations which can help you select the best device for your needs. Begin with your water testing results. You can buy test kits at hardware stores or home improvement centers, or have your water professionally tested. Contact your state EPA office for more information. Knowing the contaminants present in your water can help you select the proper system. Bear in mind that your water treatment solution may include more than one device. For example, your reverse osmosis system will work best if your water is treated with a water softener first.
Water Filter Maintenance
Investigate what maintenance is needed for the system as part of your decision-making process when you buy a water filter. Filter systems will require frequent filter cartridge replacements. Some systems, such as a water softener, require frequent maintenance. Ozone generators used for removing bacteria in water will need a new ozone bulb about every two years. Maintenance will add to the cost of your water filter system.
