Hydroviv individually optimizes every system that leaves our production facility. Our “Water Nerds” analyze water quality data from local, county, state, and federal databases to help determine present contaminants in your drinking water. Using your shipping address, we’re able to assemble a filter based on what we find. If you’re on a private well, we use the USGS groundwater database, source water assessments, and land use data. If you've recently had your well water tested, you're more than welcome to email us a copy at firstname.lastname@example.org. When it comes time to order a replacement cartridge, we’ll check your municipalities most recent Consumer Confidence Report to see if anything has changed. We've got your back!
