Direct flow reverse osmosis 200 GPD

Direct flow reverse osmosis 200 GPD – tankless under-sink water filter

The direct flow reverse osmosis 200 GPD system is a tankless under-sink unit from the Economy Water family, described as one of the newest models. It produces pure water on demand, so water does not stand in a tank and there is no risk of bacteria growing in it. The system uses two high-performance 100 GPD RO membranes; the manufacturer states a filtration precision of 0.0001 µm and 95 % removal of impurities.

Conventional reverse osmosis systems store water in a pressurized tank that takes up space under the sink. The direct flow reverse osmosis 200 GPD has no tank, so the unit is more compact and pure water flows from the tap the moment you open it. The unit needs an electrical connection to operate.

• Tankless: water is filtered on demand.
• 2 × 100 GPD membranes, 200 GPD in total.
• Waste-to-pure water ratio 1 : 1 (3 : 1 for conventional systems according to the manufacturer).
• Adjustable hardness via a bypass valve.
• Flow rate 0.7–0.9 L/min at 1–6 bar operating pressure.

Filtration stages: direct flow reverse osmosis 200 GPD

In the direct flow reverse osmosis 200 GPD system, water passes through these stages:

1. 5 µm sediment filter holds back sand, rust and larger particles,
2. activated carbon reduces chlorine and its derivatives and chemicals,
3. 1 µm sediment filter protects the membranes,
4. two high-performance 100 GPD RO membranes retain the remaining contaminants.

According to the manufacturer, the system removes sediment, rust, sand, limescale, chlorine, chemicals, heavy metals, nitrates, arsenic, hormones and pharmaceutical residues, viruses, bacteria and radioactive particles. The page gives no independent measurements, so treat this as a manufacturer claim.

Advantages: direct flow reverse osmosis 200 GPD without a tank

Besides saving space and delivering fresh water, there is less wastewater: 1 : 1, versus 3 : 1 for conventional systems according to the manufacturer. You adjust water hardness with a bypass valve, so no mineral additive is needed. The manufacturer also states cheaper and simpler maintenance. If you prefer a system with a tank or remineralization, see the PurePro ERS105 or the Ecosoft Pure Balance, and for a compact unit with a pump the PurePro M500P.
