How to Clean a Water Filter

Many people enjoy the benefits of a home water filtration system. However, maintaining a clean water filter can often be frustrating and costly. Purchasing a new water filter every few months is far more expensive and harmful to the environment than cleaning and reusing a water filter you already own. Finding the correct filter for your system can also become challenging, since many stores carry limited brands and models. A simple alternative to replacing a water filter is to learn how to clean and reuse it.

Water Filter
Bucket of Water

Take all supplies to a well-ventilated area, preferably outdoors. Put on protective equipment before mixing the muriatic acid. Fill one bucket with 1/2 gallon water.

Muriatic Acid

Slowly pour 2 cups of muriatic acid into the bucket of water. Use a long plastic stirrer to gently mix until thoroughly blended. Set the bucket aside.

High-Pressure Hose

Use a high-pressure hose to spray debris loose from the water filter. Hose down each side of the filter, concentrating on areas with rust and calcium buildup.

Step 4

Submerge the water filter in the bucket containing the muriatic acid solution. Place the bucket in a secure ventilated area away from pets and minors. Let the filter soak in the muriatic solution for five days.

Step 5

Pour 1/2 gallon water in a separate bucket. Remove the water filter from the muriatic acid, and place in the bucket of water for 5 minutes. Remove filter from the water, and rinse thoroughly with a high-pressure hose. The water filter may now be reinstalled into the water filtration system.
