Enjoy convenient access to purified drinking water at home with the Ecosoft Standard PRO Reverse Osmosis System with Mineralisation. Designed for installation beneath the kitchen sink, this five-stage domestic water filtration system combines sediment filtration, activated carbon treatment, reverse osmosis membrane technology and a final mineralisation stage.

The system is designed to reduce a wide range of unwanted substances in mains water, including suspended particles, chlorine and dissolved impurities. Its 50 GPD reverse osmosis membrane provides a nominal production capacity of up to 190 litres per day, while the integrated storage tank keeps purified water available when you need it.

A final mineralisation stage adds minerals back into the treated water, helping to improve its taste after reverse osmosis filtration.

With no electrical supply or booster pump required, the Ecosoft Standard PRO is a practical under-sink drinking water solution for households with suitable mains water pressure.

Five-stage reverse osmosis water filtration

The Ecosoft Standard PRO uses five stages of water treatment to provide a comprehensive domestic drinking water filtration process.

Stage 1 – 5 Micron Sediment Filtration

A polypropylene sediment filter captures suspended particles such as sand, rust, silt and other visible impurities. This initial filtration stage helps protect the downstream carbon filters and reverse osmosis membrane.

Stage 2 – Granular Activated Carbon Filtration

The granular activated carbon filter, made using coconut shell carbon, reduces chlorine and certain organic compounds that can affect water quality, taste and odour. It also helps protect the reverse osmosis membrane from chlorine exposure.

Stage 3 – 1 Micron Sediment Filtration

A finer polypropylene sediment filter removes smaller suspended particles before water reaches the reverse osmosis membrane.

Stage 4 – Reverse Osmosis Membrane

The 50 GPD reverse osmosis membrane is the main purification stage. It separates water into two streams: purified water, known as permeate, and a concentrate stream containing rejected dissolved substances that is discharged to drain.

Reverse osmosis is particularly effective at reducing dissolved salts and many other dissolved impurities. Actual performance depends on the incoming water quality, operating pressure, temperature and condition of the membrane.

Stage 5 – Mineralisation

After reverse osmosis, water passes through the mineralisation cartridge. This adds minerals back into the purified water, helping to improve its taste and provide a more balanced drinking-water profile.

Designed for everyday drinking water at home

The Ecosoft Standard PRO is designed as a point-of-use water purification system, supplying treated drinking water through its own dedicated kitchen tap.

The integrated pressure storage tank holds purified water so it is available on demand, rather than requiring the membrane to produce water at the full drinking-tap flow rate.

The system operates without electricity, making it a straightforward solution for homes with adequate incoming water pressure.

Key features and benefits

• Five-stage filtration: Combines sediment, activated carbon, reverse osmosis and mineralisation technologies.

• 50 GPD membrane: Nominal production capacity of approximately 190 litres per day under rated conditions.

• Mineralisation stage: Adds minerals back into the purified water to help improve taste.

• Dedicated drinking water tap: Supplies treated water separately from the standard kitchen tap.

• Integrated storage tank: 12-litre total tank capacity, with up to 7 litres of usable water.

• No electricity required: The standard model operates using mains water pressure without a booster pump.

• Under-sink installation: Designed to fit beneath a domestic kitchen sink.

• Replaceable cartridges: Routine maintenance can be carried out by replacing the appropriate filter elements.

Installation requirements

The Ecosoft Standard PRO is designed for connection to a cold mains water supply.

The standard non-pumped version requires an incoming water pressure of 3–6 bar. If your household water pressure is below this range, a booster-pump model may be more appropriate.

The system also requires a suitable drain connection for the concentrate water produced during reverse osmosis filtration, as well as sufficient space beneath the sink for the filter assembly and storage tank.

Installation should follow the manufacturer's instructions. Check all connections for leaks after installation and monitor the system regularly during its initial operation.

Filter replacement and maintenance

Regular cartridge replacement is essential for maintaining filtration performance and protecting the reverse osmosis membrane.

Ecosoft recommends the following general replacement intervals for this system:

Component	Recommended replacement interval
Pre-filter cartridges	Every 3 months
Reverse osmosis membrane	Approximately every 12 months
Mineralisation cartridge	Approximately every 6 months

These intervals are guidelines. Actual replacement frequency depends on incoming water quality, daily water consumption and operating conditions.

The purified water should also be tested periodically, including monitoring its total dissolved solids (TDS), to check that the reverse osmosis membrane continues to perform satisfactorily.

Is the Ecosoft Standard PRO right for your home?

The Ecosoft Standard PRO is a good choice for households looking for a traditional under-sink reverse osmosis water filter with an integrated mineralisation stage.

It is particularly suitable if you want:

• A dedicated supply of purified drinking water.

• A multi-stage filtration system for domestic mains water.

• Reverse osmosis filtration to reduce dissolved impurities.

• Mineralisation to improve the taste of treated water.

• A storage tank to provide water on demand.

• A system that does not require an electrical connection or booster pump.

If your incoming water pressure is consistently below 3 bar, consider a pumped reverse osmosis model instead.
