The Brio SIMPL Tankless Reverse Osmosis Undersink Filtration System (TROM600STD) is an under-sink drinking water system that produces filtered water on demand without a storage tank. It is intended for use with municipal cold water supplies and is professionally installed at the point of use, connecting to the cold water line and dispensing through a dedicated faucet.
The system uses a two-cartridge filtration process: a PAC (pre-activated carbon) filter and a reverse osmosis (RO) membrane. The PAC filter removes dirt, silt, and other suspended solids, along with chlorine and unpleasant tastes, odors, and colors. The RO membrane is rated at 0.0001 micron and removes up to 99% of contaminants, including total dissolved solids, fluoride, and heavy metals such as lead and arsenic. Brio markets this arrangement as "4-in-2" filtration, referring to a four-stage treatment process carried out across the two cartridges.
This model has a daily purified production rate of 600 GPD and a recovery rate of 1.5:1 pure to waste. Its tankless design occupies a compact under-sink footprint, and both filter cartridges are front-facing for quick-change replacement. A touch interface on the unit indicates filter life and power status. The system ships with the filtration unit, a brushed nickel filtration faucet, both filters, and an installation kit.
