Three Stages, Three Lifespans

Sediment and carbon cartridges are consumables measured in months. A membrane runs for years, as long as the carbon ahead of it is doing its job. DI resin is finished when it is finished — anywhere from weeks to most of a year depending on source water, and only a TDS reading will tell you which.

What's Here

• Sediment cartridges — 1 micron filters removing particulates ahead of the carbon.
• Carbon block cartridges — extruded carbon that strips chlorine before it reaches the membrane.
• RO membranes — 50 and 100 GPD replacements.
• Bulk DI resin — sold in 1.2 lb and 5 lb quantities.
• DI cartridges and refillable shells — pre-filled cartridges, plus shells you refill from bulk.
• System-specific sets — replacement cartridge packs matched to particular RO units.

Keep the carbon on schedule. Chlorine damages thin-film membranes, so a spent carbon block quietly costs a component worth many times what the block did. If resin turns over quickly in your setup, refilling shells from bulk works out considerably cheaper than buying fresh cartridges each round. Questions? Email info@jlaquatics.com.
