2540 RO Membrane
SpiroPure membranes from All Filters are an excellent choice for smaller commercial systems and other RO applications. Brackish water options like the BW2540 help provide high-performance treatment of TDS. For high-salinity applications, the SW2540 seawater desalination provides high rejection of salt for the treatment of seawater and other demanding desalination needs.

Finding the Ideal RO Membrane
All Filters makes it easy to identify compatible products using our specifications and cross-reference charts. Simply follow this guide to find a compatible filter.
Specifications Chart
If you know the product details of your 2.5” x 40” RO membrane, you can use the specifications chart. The specifications chart lists the main performance details of brackish and seawater desalination membranes. This information includes measurements like rejection rate, average permeate, and salinity level.
Brackish water membranes use less pressure and energy to purify water with moderate salt levels, like river or well water. On the other hand, seawater desalination membranes can handle high salt concentrations that are found in ocean water, as they use high pressure and provide superior salt rejection. The 2.5" x 40" membrane is one of the most popular sizes for onboard watermakers on sailboats and yachts.
Cross-Reference Chart
If you know the brand and model of your current 2540 RO membrane, you can use the cross-reference chart to find the corresponding SpiroPure replacement.
Simply find the 2.5” x 40” membrane type in the chart, whether it’s seawater desalination or brackish water. Then, compare your branded model to the SpiroPure equivalent in the same row.
