The RainTree™ System
The RainTree™ Tankless Undersink System is an advanced multi-stage, point-of-use drinking water purification system which produces superior quality, great tasting water for a fraction of the cost of bottled water.
0.01 micron Ultrafiltration means you can say goodbye to Microplastics!
Arrives pre-assembled so all you have to do is connect it to your water line.
NO electricity, pump, or waste line.
Filter replacement is easy too! Once a year, pull the colored caps off the filter ends and pop the used filters out. Snap the new ones in, flush, and you’re all set.

We offer single filters and pre-filter sets for individual purchase.
