Make a Homemade Water Filter
Over the last decade, commercial water filtration pitchers and tap purifiers have become popular products for improving the taste of drinking water by reducing the presence of trace minerals like iron and sulfur. Though the effects of these filters may seem miraculous, they function using simple principles and easy-to-replicate materials. So if your water needs freshening, but you can't buy these products (or just want to save the money), you can create your own similar filter for a fraction of the cost.
Instructions
1. Line the strainer with a coffee filter. For best results, the entire inside of the strainer should be covered, so if you have the option of using a small enough strainer to allow this, do so.
2. Measure about 2 tbsp. of charcoal and spread it across the bottom of the filter lining. You may need to adjust the amount according to the size of your strainer, so use enough charcoal to fully cover the bottom of the basket (it's okay to have a little extra).
3. Select a second coffee filter and trim it. Press the filter on your work space to flatten the crimped edges, then use your scissors to trim about a half an inch around the outside. Trimming this inner filter will prevent it from covering up the outer filter, allowing you to see if the outer portion starts to slip down and let out particles of charcoal.
4. Cover the first filter and charcoal with the trimmed coffee filter.
5. Pour water through the completed filter to purify. Store in the fridge when not in use to prevent mold or mildew from the moisture.
6. Replace the coffee filters as needed if they become clogged or tear. The charcoal will need to be replaced periodically as well, but how often depends on your water, so judge based on the taste you notice.
