yes, you can drink rainwater with Wisy rainwater filters.Collect rainwater from your roof, filter it using our Wisy Rainwater Filter, and store it in a sealed sump. The water remains safe for drinking for up to five years without mixing with other sources. As it’s filtered, the process aerates the water without needing electricity, enriching it with oxygen for added purity. The filter captures particles as small as 250 microns, and any bio-waste is converted into biofilm due to the oxygen enrichment. No centrifugal force is required for filtering, and even drizzle can be filtered. The water won't stagnate on the roof because the inlet and outlet pipe sizes are the same.
