How It Works

Our technology allows us to remove even the smallest viruses while having holes that are 100x the size of our competitor’s for an unprecedented flow rate.

Other Filters

Most filters work by trying to force contaminated water through tiny holes that block polluting matter from getting through.

Our Filters

Instead, our Rorus Core works like a magnet. As water flows through, the pathogens are attracted and attached to our filter material, removing them from the water.
