Have a different Culligan system? AC-30, AC-15 and AC-50 use different sets. Find your model on our Culligan replacement filters page, or call (714) 541-6600 and we'll match it for you.

This set replaces all three filter stages on a Culligan H-52 or H-53 under-sink reverse osmosis system: a 5 micron sediment pre-filter, a coconut carbon block and an inline GAC post-filter. It's the routine filter change most systems need every 6 to 12 months, without paying for a membrane you don't need yet.

WHAT'S INCLUDED

Three Filter Stages

⚪

Stage 1: 5 Micron Sediment

Meltblown polypropylene pre-filter that catches sand, silt and rust before they reach the carbon and the membrane.

🔵

Stage 2: Coconut Carbon Block

10 micron coconut shell carbon block (1.9" × 11.62") that reduces chlorine, taste and odor, protecting the membrane from chlorine damage.

💧

Post-Filter: Inline GAC

Omnipure K2333-JJ, 6" × 2" coconut shell GAC with 1/4" quick-connect ends. Final polish for clean-tasting water at the faucet.

COMPATIBILITY

System Fit

Made for Culligan H-52 and H-53 under-sink reverse osmosis systems, part of Culligan's Aqua-Cleer Good Water Machine line. Check the model label on the side or top of your unit before ordering. Replace the sediment and carbon filters every 6 to 12 months and the post-filter about once a year, or sooner if you notice slower flow or a change in taste. Most membranes last 2 to 3 years, depending on water quality.

Compatible aftermarket replacement. Isopure Water is not affiliated with Culligan.
