  • 1. A single point, tank-top filter with a ground breaking U-shaped design.
  • 2. Multiple Barriers (2mm and 180 micron) filter particles 5 times smaller than is achieved with a standard tank screen.
  • 3. Reduces the hassle of cleaning leaf and debris build-up through self-flushing.
  • 4. Blocks out light, replacing tank screen and solar shield if positioned on top of the tank.
  • 5. Is a versatile product, able to be installed in a variety of pre-tank locations.
  • 6. Reduces frequency and cost of tank cleaning by lowering common sediment build up through cleaner tank water.


  • 1. Rainwater enters the Maelstrom through either of the horizontal-facing couplings.
  • 2. The rainwater then enters the Primary Filter. The unique curved filter slows the velocity of the water by changing the direction of its flow.
  • Surrounding the Primary Filter is a Secondary Filter, comprising of a nylon mesh bag which filters fine particulates larger than 180 micron. This filter assembly is easily removable and will require periodic maintenance.
  • The filtered rainwater then continues to move through the Maelstrom to the filtered water outlet and into the rainwater tank or pipe (if attached).
