VerterPure VP6 water filter purifier uses advanced UVC-LED technology that can reduce harmful contaminants by 4 LOG (99.99%) from water without adding any chemicals. It is activated on-demand, controlled by a smart flow switch. This design not only minimizes the power consumption, but also expands its life-time. It is compact in size, suitable for a limited space like RV, boats, etc. DuoPro S2 two-stage RV water filter system is designed above & beyond standard inline filters to protect against a wide range of contaminants, including chlorine, bad taste, odors, and more. The first stage acts as a pre-filter, extending the life of the second stage. This pre-filter is equipped with a 5-micron sediment PP filter, effectively removing heavy sediments, chlorine, bad taste, and odor. The second stage filter, a 5-micron carbon block cartridge, protects against lead, volatile organic compounds (VOCs), & other contaminants.
