High-capacity MaxCap in the 3" × 10" shell — 33% more resin than the standard MaxCap, so it absorbs more incoming TDS before exhaustion. Drop-in upgrade for setups where the standard MaxCap is cycling too quickly.

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.
