SpectraPure® SpectraSelect® Plus 99% Rejection RO Membrane 90GPD

SKU: MEM-SP-0090


SpectraPure® SpectraSelect® Plus™ 99% Rejection Membranes set the industry standards for contaminate removal, high flow rate, and membrane longevity. Using a proprietary process, SpectraSelect Plus™ membranes are pre-treated to enhance rejection and increase product water production, while effectively doubling post deionizing cartridge life.

SpectraSelect membranes are hand-picked and individually tested for consistent ultra-high rejection ratios.

No other membrane can match SpectraSelect Plus™ for membrane life, or the ability to remove silica, phosphates, nitrates, and heavy metals.

SpectraSelect Plus™ Membranes are standard equipment in SpectraPure MaxCap™-AF & -MF RO/DI Systems, SpectraPure UHE RO/DI Systems, and are now included in SpectraPure’s newly upgraded CSPDI -AF & -MF RO/DI Systems.

They are can be used as an upgrade replacement option for most residential / aquarium Reverse Osmosis or RO/DI Systems and are interchangeable with Captive Purity™, Kent Marine® and other standard-sized TFC membranes.

William Hickey
Scheduled maintenance

Its strangely pleasing to take apart the rodi unit, cleaning every piece and putting in brand new filters and membrane. Spectrapure treats its customers very well which is why I purchase all my replacement filters from them and will continue to do so for the excellent customer service

Hello William,
Hope it continues to be something you enjoy, thanks for the review.
