Specialty Inline & Purpose-Built Filters
Beyond basic sediment and carbon, some jobs need a purpose-built cartridge. We carry specialty inline filters from Omnipure, Pentek and Aries — scale-inhibiting, remineralizing (calcite), nitrate-reducing, softening and KDF-blended cartridges — for the fine-tuning that makes water taste and perform exactly right.
How to choose a specialty filter
Remineralize RO water. Calcite inline filters add back calcium and lift pH for better taste after reverse osmosis.
Scale-inhibitor inline. GAC + phosphate cartridges protect icemakers and espresso machines from scale.
Targeted reduction. Nitrate, KDF and softening inline cartridges handle specific problems in a small footprint.
Match size & fitting. Inline cartridges come in 10"/12" x 2"–2.5" with 1/4"–3/8" quick-connect or FPT ends — match your line.
Tell us the job and line size and we'll match the specialty filter. Start here.
