Reverse osmosis membrane, 100 GPD, encapsulated, 1/4" quick-connect fittings

The reverse osmosis membrane  is the core element of any modern water purification system using reverse osmosis technology. Thanks to its compact in-line design and 1/4" quick-connect fittings, it integrates easily into both classic tank-based systems and modern tankless solutions, making it a reliable choice for residential, HoReCa, or technical applications.

Molecular-level filtration performance

The spiral-wound semipermeable membrane removes 96% – 99% of dissolved and suspended contaminants from water, including:

• mechanical particles and fine sediments
• most bacteria and viruses
• volatile organic compounds (VOCs)
• heavy metals and dissolved ions (sodium, chlorine, lead, arsenic, nitrates, etc.)
• total hardness (calcium, magnesium)

The filtration threshold reaches 0.0001 microns — on the scale of ions — delivering pure, safe, and great-tasting water, ideal for drinking, cooking, and brewing coffee or tea.

Under normal operating conditions and with proper pre-filtration (sediment + activated carbon), the In-Line membrane provides a service life of up to 18 months. The actual lifespan depends on the hardness and quality of the feed water, working pressure, and frequency of use.

Technical specifications

• Type: reverse osmosis membrane, in-line configuration
• Capacity: 100 GPD
• Salt rejection efficiency: 96 – 99%
• Filtration threshold: 0.0001 μm
• Connections: 1/4" stem (quick-connect fitting, no additional adapters required)
• Dimensions: Ø 60 mm × 270 mm
• Service life: up to 18 months

Compatibility

Thanks to the universal quick-connect 1/4" connection standard, the membrane is compatible with most in-line reverse osmosis systems available on the market, including configurations with 4, 5, or 6 filtration stages.

💡 Technical recommendation: To maximize the membrane's service life and performance, make sure the pre-filters (minimum 5μ sediment and activated carbon) are replaced every 6 months. The water reaching the membrane must be free of free chlorine.
