A mobile resin filter that makes pure water straight from a municipal tap as you work. Put it between the tap and a waterfed pole and you can move from building to building without carrying a reverse osmosis plant.
In the kit
- 20 inch Big Blue housing
- 20 inch Big Blue refillable housing
- Mixed-bed deionising resin
Resin or reverse osmosis?
Resin is the most portable option: no plant, no tank. A reverse osmosis system such as the RO trolley makes water continuously, with no resin to refill. Check the output with a TDS meter to know when the resin needs refilling.
