The Mega MaxCap is the highest-capacity lab-grade DI cartridge on the market — and the best roughing DI you can put in front of a finishing stage. It strips out residual ammonia, phosphates, and trace ions that slip past the RO membrane, so your downstream mixed-bed or SilicaBuster cartridge can stay at peak purity for far longer.
What it does
The Mega MaxCap runs as a "roughing" DI stage. Put it ahead of any mixed-bed, SilicaBuster, or layered-bed finishing cartridge and you'll process 4× or more DI water by volume before that finishing stage needs replacing.
Features
- Re-formulated for 2023 — custom resin blend with higher capacity and longer life than the legacy version
- 3.5× the capacity of a conventional mixed-bed or high-silica cartridge
- Removes residual ammonia and ionized impurities from the RO stream
- Improved phosphate removal
- Standard twist-top shell: 3" dia × 10" L — fits virtually all standard 10" filter housings
- Interchangeable with Captive Purity, Kent Marine, AWI, BRS, and most residential/aquarium RO/DI systems
- Aluminized packaging prevents resin degradation in storage

Cleaner water for plants, pets, and people
Reverse osmosis membranes reject microplastics, PFAS and "forever chemicals," chlorine and chloramine byproducts, heavy metals, and the dissolved solids that show up as taste and scale. That means cleaner feed water for your plants, animals, business, or family — and a lot less reliance on bottled water, which keeps plastic out of the landfill. Most setups run a 3:1 waste-to-product ratio on hard water and 2:1 on soft water, and can be tuned to 1:1 in high-purity feed areas or with a periodic pure-water flush. The system is built to last with field-serviceable filter housings, so you replace cartridges (not whole units) for years of dependable purity.
Note: DI water is not intended for drinking. DI resin is not made from food-grade material.
