SpectraPure SpectraSelect Plus 90 GPD RO Membrane

SpectraPure SpectraSelect Plus 90 GPD RO Membrane

SKU: T764

The SpectraPure SpectraSelect Plus 99 Percent Rejection 90 GPD RO (MEM-SP-0090) Membrane sets industry standards for high rejection rates, flow rate, and longevity. Treated with a proprietary process for enhanced rejection and increased production, these membranes are individually tested for consistent ultra-high rejection. They effectively double the lifespan of post-deionizing cartridges by removing contaminants like silica, phosphates, nitrates, and heavy metals. With a typical stabilized conductivity rejection of 99% and guaranteed minimum conductivity rejection of 98%, these membranes produce water at a rate of ± 10% at 60 psi, making them a reliable and efficient choice for water purification systems.

SpectraPure® Spectra Select Plus™ 99 Percent Rejection 90 GPD RO Membrane


NOTE:  Membrane must be stored in the refridgerator if not being installed immediately.


SpectraSelect Plus™ membranes set the industry standards for highest rejection, flow rate, and longevity.  SpectraSelect Plus™ 99% Rejection Membranes effectively DOUBLES post Deionizing cartridge life!

SpectraPure®SpectraSelectPlus™ membranes are treated with a proprietary process to enhance rejection, increase production and speed rinse up times. These treated membranes are then  hand-picked and individually tested for consistent ultra-high rejection. No other membrane can match the SpectraSelectPlus™ for long life and the ability to remove silica phosphates, nitrates, and heavy metals.


SpectraSelectPlus™ Membranes are standard equipment in our CSPDI-MF modeals, MaxCap-MF models, and UHE RO/DI Systems and can also be used available as an upgrade replacement option for most Reverse Osmosis Systems, and are interchangeable with Captive Purity™, Kent Marine®, Air Water Ice®, Bulk Reef Supply®, and most residential/aquarium RO or RO-DI systems.


Why the SpectraSelectPlus™ 99% Membrane Saves You Money.
SpectraPure’s SpectraSelectPlus™ membranes are individually tested at our factory and treated with a proprietary process to enhance rejection and increase production in order to assure that you receive the highest possible rejection rate right out of the box!

RO/DI systems use an RO membrane to remove the majority of the contaminants in the tap water. The DI resins remove all of the contaminants that make it past the membrane. The RO membrane is the most economical means of purifying water while the DI resins are the most expensive. 

Dow® states its minimum rejection rates as 96%.


A 99% rejection membrane will pass one-fourth of the impurities of a 96% membrane, thereby quadrupling the life of
your DI cartridges! 

Most membranes are shipped dry. They require a “rinse up” time to flush the membrane of the wetting agents used to preserve the
membrane and for the rejection rate to stabilize.  SpectraSelectPlus™ membranes have been pre-rinsed and individually tested in our facility and are shipped wet. This means
that you obtain the performance you expect “right out of the box” without subjecting your DI cartridges to the shock of initial startup.
