Can coffee filters be used to filter water?

While coffee filters can trap larger particles and debris, they are not designed to remove contaminants like bacteria, heavy metals, or chemicals. They are suitable for basic pre-filtration but should not be relied upon for safe drinking water. Certified filtration systems, such as reverse osmosis filters like the Elite Series 3 RO Filter, provide advanced filtration to ensure your water is free from harmful impurities, making it safe for consumption.
