1812 RO Membrane Filter
The 1812 RO Membrane Filter is the semi-permeable membrane at the heart of domestic and office under-sink reverse osmosis units; separating out the dissolved salts, heavy metals and fine contaminants in the water, it carries out the most critical stage of treatment, and its standard 1812 size fits most domestic units.

01Problem & Solution
When the Membrane Tires, the Treatment Stops
Problem
People Assume the Filters Are Enough
Pre-filters capture only sediment, chlorine and odour; they cannot remove dissolved salts and heavy metals. When the membrane tires the unit carries on running, but the quality of the treatment falls and the taste and TDS of the water go with it.
Solution
Renew the Membrane on Time
The 1812 RO Membrane Filter is the stage that does the unit’s real work. Renewed, the water quality and the rate of production return to what they were on day one.
02Key Features
The Stage That Does the Real Work
The 1812 RO Membrane Filter is designed to deliver the highest level of treatment in a domestic unit.
A Semi-Permeable Structure
It lets water through while holding back the great majority of dissolved salts, heavy metals and fine contaminants.
Standard 1812 Size
At 1.8 inches in diameter and 12 inches long it fits the great majority of domestic and office units.
Heavy Metal Removal
It separates out the heavy metals and dissolved matter that pre-filters cannot remove.
It Brings the Water Quality Back
Renewed, the taste, the clarity and the TDS of the water return to where they were on day one.
Easy Replacement
It is changed easily by withdrawing it from the membrane housing and fitting a new one.
A Range of Capacities
It is made in different GPD ratings, and the one matching your unit’s capacity should be chosen.
03Technical Specifications
Membrane Specifications
| Feature | Value | What it does |
|---|---|---|
| Product Type | RO Membrane Filter | Which family the unit belongs to. Products in the same family can be used in place of one another. |
| Size | 1812 (1.8" × 12") | The physical size. If a spare does not match this, it will not go into the housing. |
| Technology | Reverse Osmosis | The treatment technology used. Reverse osmosis takes out salts and heavy metals; carbon takes out taste and odour. |
| Construction | Semi-Permeable Film | How the unit is put together. A compact cabinet takes little room; an open system makes servicing easier. |
| Its Place in the System | After the Pre-Filters | |
| Use | Domestic · Office RO | What setting it was designed for. A domestic unit will not carry a commercial load. |
| Weight | 1 kg | Product weight. For wall mounting, the supporting surface is chosen accordingly. |
| Dimensions | 5 × 5 × 20 cm | The outer dimensions of the unit. The cabinet or plant room has to be wider than this. |
04Applications
Where Is It Used?
The 1812 RO Membrane Filter is used in every under-sink reverse osmosis unit.
- Domestic RO Systems
- Under-Sink Units
- Pumped Units
- Pump-Free Units
- Offices
- Filtered Water Dispensers
- Small Businesses
- Membrane Replacement
05How It Works
How Does the 1812 RO Membrane Filter Work?
-
Through the Pre-Filters
The water passes first through the sediment and carbon filters, which capture coarse sediment and chlorine and protect the membrane.
-
Into the Membrane Under Pressure
Under mains pressure or with the help of a pump, the water is delivered into the housing holding the membrane.
-
Through the Semi-Permeable Film
The water molecules pass through the film while dissolved salts, heavy metals and fine contaminants stay behind.
-
Treated Water and Reject Separate
The treated water goes to the tank, and the reject carrying the contamination is discharged to drain through a separate line.
-
Renewal When It Tires
When the membrane tires, production slows and water quality falls; it should be replaced.
06Making the Right Choice
What Decides the Right Membrane
When choosing the 1812 RO Membrane Filter, unit compatibility and capacity must be assessed correctly.
Unit Capacity (GPD)
The membrane’s GPD rating must match the capacity your unit was designed for.
Housing Compatibility
1812 is the standard size, and your membrane housing should be confirmed as suiting it.
Mains Pressure
On pump-free units low pressure slows production, and a pumped model is then the better choice.
The State of the Pre-Filters
The pre-filters should be changed when a new membrane is fitted, or the membrane wears out quickly.
07Maintenance and Use
Notes That Extend Its Life
- The pre-filters should be changed on time; a spent carbon filter cannot hold the chlorine back and the membrane is permanently damaged.
- Watch the flow arrows when changing the membrane; fitted the wrong way round, it treats nothing.
- The first tankful after a change should be emptied, flushing out manufacturing residue and fine dust.
- In units left unused for a long time the membrane must not dry out; staying wet inside the housing preserves its life.
08Frequently Asked Questions
Common Questions
What does the 1812 RO Membrane Filter do?
It is the stage that does the real treating in domestic and office reverse osmosis units. Its semi-permeable structure separates out the great majority of the dissolved salts, heavy metals and fine contaminants in the water.
What does “1812” mean?
1812 is the element’s standard size: roughly 1.8 inches in diameter and 12 inches long. It is the standard membrane size used in the great majority of domestic and office under-sink units.
How does it differ from the pre-filters?
Pre-filters capture only sediment, chlorine, off-taste and odour. The membrane separates out dissolved salts and heavy metals; that is where the real treatment happens. The pre-filters are the membrane’s protection, and the membrane is the heart of the unit.
When is it changed?
Membrane life depends on the quality of the incoming water, how heavily the unit is used and whether the pre-filters have been changed on time. A marked drop in production, or a change in the taste and TDS of the water, shows that it is time.
Which GPD rating should I choose?
1812 membranes are made in different GPD (daily output) ratings. The rating you choose must match the capacity your unit was designed for, so your unit’s model needs to be known.
