Camco's Evo X3 Triple Stage Premium RV Water Filter Kit offers superior RV water filtration. It is rated at 0.2-microns to filter and minimize even more contaminates, including: viruses, bacteria, chlorine, bad taste, odors, sediment and other contaminants from your fresh water supply. The result is fresh, clean, great-tasting water straight from your tap. It is capable of providing high flow throughout your RV-even allowing uncompromised water flow in your shower. With triple stage filtration, the first stage acts as a pre-filter, extending the life of the next 2 cartridges. It is comprised of a 5-micron sediment cartridge that contains KDF and GAC to remove heavy sediments, chlorine, bad tastes and odors. The second stage filter contains a 0.5-micron carbon block cartridge that offers protection against lead, volatile organic compounds (VOCs), chloramines, giardia and other contaminates. The third stage filter contains a 0.2-micron electropositive pleated cartridge that helps remove viruses, bacteria and cysts from your water. The Evo X3's heavy-duty, powder-coated metal chassis provides a sturdy base between your water source and your RV's fresh water connection. Features nickel-plated brass male fitting and swiveling female fitting for easy setup between your water source and your RV's fresh water connections.
