Product description


The Famous Mega MaxCap has been Re-Formulated for 2023 with an all-new custom blend of resin that increases the already outstanding capacity and longevity of the best Pre-DI cartridge on the market!

Like the legacy MaxCap cartridges, the Mega MaxCap functions as a “roughing” DI stage, by removing the vast majority of residual ammonia, phosphates, and other trace ionized impurities that have passed through a purification system’s RO membrane.

This pre-processing improves RO water chemistry to the degree that the downstream mixed bed and/or layered bed DI resins in subsequent “finishing” stages will continue to perform optimally for far greater durations, processing 4 times or more DI water by volume than otherwise possible.

The newly formulated Mega MaxCap DI’s higher capacity and enhanced phosphate removal provides even greater overall DI cartridge life; processing even more water and extending the life of down-stream finishing DI cartridges even better than its predecessor.

The Mega MaxCap DI should be used ahead of any indicating or non-indicating Mixed Bed, SilicaBuster, Enduro DI, or other conventional Mixed Bed DI “finishing” cartridges, to greatly extend cartridge life, thus requiring far fewer replacements over time.

Enjoy consistently ultra-pure DI water, and water production cost savings.


- Standard Twist-top shell, 3in dia x 10in L, fits in virtually all standard 10inch filter housings

- Roughing DI cartridge designed to be placed ahead of a Mixed Bed, SilicaBuster™ or other finishing DI stage

- Newly Formulated and Improved performance over the legacy Mega MaxCap

- 3.5 times the capacity of conventional Mixed-Bed and Hi-Silica removal cartridges

- Removes residual ammonia and ionized impurities from RO stream

- Improved phosphate removal and extended cartridge longevity 

- Aluminized packaging eliminates resin degradation while in storage

- Interchangeable with Captive Purity, Kent Marine, AWI, BRS, and most other residential or aquarium DI or RO/DI systems

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