Clean water is fundamental to health. With increasing concerns about lead pipes, agricultural runoff, and disinfection byproducts in municipal water supplies, a quality water filter is a smart investment for every household.
Types of Water Filtration
Different filtration technologies remove different contaminants. Activated carbon removes chlorine, VOCs, and improves taste. Reverse osmosis removes almost everything. Understanding what's in your water helps you choose the right filter.
