Product description

SpectraPure®’s Mega MaxCap® 5-Stage High Efficiency RO/DI Systems are designed to produce ultra pure de-ionized water at optimal efficiency, while simplifying DI cartridge monitoring and replacement. This upgraded MaxCap® System is comprised of 0.5 Micron MicroTec Sediment and 0.5 Micron Carbon Block pre-filtration stages to remove sediments, chlorine and other impurities, before passing feed water to the individually tested 98% Rejection SpectraSelect Plus RO Membrane(s).

The system’s DI stages work together to reliably produce even greater volumes of ultra pure (18.2 megohms) deionized water while extending overall DI cartridge life. This translates to fewer DI cartridge changes over time. SpectraPure® has optimized DI performance by incorporating their latest unique blends of laboratory grade resins into a new and improved Mega MaxCap® DI Cartridge. With the Mega MaxCap® roughing DI stage followed by our new Enduro™ DI polishing stage, virtually all remaining ionized impurities, silica and phosphates are removed, producing the purest DI water and increased DI cartridge longevity.

The Mega MaxCap® 90 GPD RO/DI System includes a pressure gauge on the membrane feed, ASO valve, comes plumbed with a Manual Membrane Flush Valve to help assure long RO membrane life and two dual TDS meters to monitor membrane feed and RO product water TDS, as well as DI cartridge output purity. Enjoy improved DI system performance, extended reliability, ease of monitoring, maintenance and plenty of ultra high purity DI water at a lower cost per gallon!

Membrane Information

90 GPD Systems = MEM-SP-0090

150/300 GPD Systems = MEM-SP-0150

  • Typical stabilized conductivity rejection 99%, min. conductivity rejection 98%.
  • Membranes produce rated GPD ± 20% at 60 psi.
  • Permeate flow and conductivity rejection based on 500 ppm, 77°F (25°C) softened water feed, 15% recovery and the specified applied pressure.

Warning: Spectrapure does not recommend drinking water produced from deionization (DI) as DI resins are typically not made of food grade approved material.

*RO and RODI systems that are installed areas with low feed-water pressure often require a booster pump to optimize system operation.
The correct Booster Pump to be used with SpectraPure’s Manual Membrane Flush (-MF) RO or RODI Systems is SpectraPure’s auxiliary High-Flow Booster Pump Kit P/N: BPHF-MF-115. This kit is designed specifically for use with SpectraPure Manual-Flush Systems. Other booster pump kits are not compatible with SpectraPure Manual-Flush (-MF) systems.

Great product as usual from Spectrapure

Saltwater aquariums require precise water quality and these filter systems never let me down.
