Finerfilters 4 Stage Domestic Undersink Reverse Osmosis System 50 GPD

Reverse Osmosis is a technology that is used to remove the large majority (98%+) of contaminants from water. The Reverse Osmosis system works by pushing the water under pressure through a number of increasingly smaller filters and finally through a semipermeable membrane, essentially trapping all contaminants.

Finerfilters are here to support you before and long after you buy. We provide help through manuals, easy install guides, diagrams, phone, and email support.

This system produces up to 190 litres per day of purified water and comes complete with:

  • A 3 US gallon pressurised storage tank holding 6.5 litres of RO filtered water.
  • Installation Manual.
  • Chrome Faucet Tap.
  • All pipes, pre-filters, post filters, and fittings required for easy installation.

Please ensure that your incoming mains water pressure meets or exceeds the recommended water pressure below before purchasing.

Finerfilters Domestic Undersink 4 Stage Reverse Osmosis System (50 GPD)

The 4 stages of Reverse Osmosis filtration are;

Stage 1
A 5 Micron sediment filter made of 100% pure Polypropylene fibres. Removes dirt, sand and rust.

Stage 2
A Carbon Block filter composed of high performance activated coconut shell carbon. Removes Chlorine Taste and Odour, Trihalomethanes, Pesticides and Volatile Organic Compounds (VOCs)

Stage 3
A high rejection, Thin Film Composite, 50GPD reverse osmosis membrane with the capacity to produce 190 Litres of purified water per day.This membrane removes contaminants present in water up to 0.0001µm including; up to 99% of dissolved salts, lead, copper, barium, bacterial by-products, oestrogen and silica.

Stage 4
A post-carbon filter designed to improve the overall taste of the water by removing any residual impurities, tastes and odours from the storage tank and provides a final conditioning stage for the purified water.

Plastic Water Storage Tank
Made of food-grade reinforced Polypropylene.
Contains a food-grade Butyl diaphragm/bladder which holds the water, ensuring tasteless, odourless & contaminant-free water.
This tank is an air bladder tank meaning the water does not touch the metal outer shell, but rests in a Butyl bladder. There is a small air charge between the outside of the bladder and the inside of the tank. It"™s this air pressure that pushes the water out of the tank when the tap is opened.
The tank is pre-charged with air but will require topping up as part of the regular maintenance of your reverse osmosis system. Air can be added using a bicycle pump or similar.

This tank can be connected to additional tanks to increase the storage capacity of your Reverse Osmosis system.

Tank uses 1/4"Female x 1/4"Pushfit Angled Shut Off Valve.

Plastic tank holds 6.5 litres of water.

Working Pressure: 50 PSI
Bottom Air Charge Pressure: 5-7 PSI
Dimensions: 36cm x 25cm x 25cm

Important Information

Reverse Osmosis systems waste water to make water, this is normal and the same with all RO systems as this is the way the membrane rejects the impure water, which goes to drain, to produce the pure water. This process requires high water pressure as the 'permeate' water is being forced through microscopic holes in order to catch contaminants. 

These systems require a minimum of 29 PSI / 2 Bar (Pumped RO Systems) or 45 PSI / 3 Bar (Unpumped RO Systems) to work. Ideal pressure depends upon incoming water temperature but around 60 PSI (4 BAR) is acceptable to produce pure water. We will always recommend purchasing an RO system with a booster pump pre-installed as this allows you to easily configure water pressure.

Membrane performance is dictated by several variables, most notably; incoming water TDS, pressure, and temperature. In order to achieve the 50GPD output stated the incoming water must match the test conditions which are; Concentration of Permeate (NaCl) = 250ppm, Water Pressure = 60 psi / 0.41MPa / 4.14 Bar, Temperature = 25°C

Because UK mains water is typically colder than test conditions we recommend that these systems are run at, or around, 80 - 90 PSI (5.5 - 6 bar). This allows the system to reduce the wastewater to pure water ratio and work quicker at producing pure water.

As many people won't have this mains pressure; pumped RO Systems or booster pumps can be purchased from us and added to the system which will increase the pressure output (a minimum of 29 PSI (2 bar) is required to operate the booster pump).

The membrane elements must be stored in a cool and dry place, away from direct sunlight. Do not expose to temperatures above 45°C

The membrane can last between 1 and 2 years depending on incoming water hardness. Filters must be replaced at least every six months for optimal performance.
