How to Change Water Filters

Common drip water filtration systems have easily replaceable filters.

Water filtration plays a major role in disease prevention. While public water filtration typically removes severely dangerous contaminants, most tap water still contains measurable levels of bacteria. Home filtration reduces contaminants, but this method is only effective if you change your filter regularly. Most filters require changing every three to four months, but this time frame varies, depending on the brand of filtration system you use.

Things You'll Need

• Adjustable wrench
• Antibacterial soap
• Sponge

Instructions

1. Turn off any water flowing through the filter if your filtration system is built into your home's plumbing. To turn off water flow, follow the pipe and locate a shut-off valve. Turn the valve clockwise to turn off water flow. For a small drip-filtration jug or container, you can skip this step.

2. Remove the old filter. On a built-in system, you'll often need to loosen a bracket or two with an adjustable wrench before you can slide the filter out. For drip-filtration systems, the filter lifts out of the unit with little or no resistance.

3. Clean the filter compartment using antibacterial soap, water and a clean sponge. Grime can build up along the edges of your filter, and it's best to remove this for cleaner water.

4. Rinse the filter compartment thoroughly using clean water. Make sure all the soap suds are gone.

5. Insert the new filter. One size does not fit all. Consult your filtration system's user manual for details.

6. Reattach any nuts removed on a built-in system, and then turn the water back on.
