The Vevor gravity-fed water filter system is a 2.25-gallon countertop unit designed to provide clean drinking water for home, camping, RV, and off-grid use. It uses activated carbon and an ultrafiltration membrane to reduce chlorine, heavy metals, sediment, rust, soil, and other impurities while improving taste. The SUS304 food-grade stainless steel body is built for durability with a seamless design that helps reduce leakage risk. Its compact, portable construction and no-electricity operation make it convenient for everyday use and travel. The included replaceable filters can purify up to 6,000 gallons per pair.
