The filtration level of a water filter refers to how thoroughly it can remove impurities from water. High-quality filters use multi-stage filtration systems, which may include sediment filters, activated carbon, and advanced technologies like ultrafiltration, reverse osmosis, or UV purification. Each stage targets specific contaminants—such as dirt, chlorine, heavy metals, bacteria, and viruses—ensuring the water is not only clean but also safe to drink. A higher filtration level means better protection for your health and improved taste and clarity of your water. Choosing the right filtration level depends on your water source and the type of contaminants present
