Omnipure - K5628 - 12" x 2.5" T40 GAC Coconut Carbon Inline Filter
K5628 Inline GAC Carbon Filter
The Omnipure K5628 uses acid-washed 12×40 mesh coconut shell GAC to remove over 95% of chlorine, along with common taste and odor compounds, fine sediment, and particulates down to the sub-micron range. This is a workhorse inline cartridge for pre-filtration ahead of reverse osmosis membranes, ice machines, fountains, and other equipment where treated municipal water still needs polishing.
K5628 Technical Data
| Model Number | K5628 |
| Dimensions | 12" length × 2.5" diameter |
| Filter Media | Acid washed 12×40 mesh coconut GAC |
| Connections | 1/4" female NPT threads (0.540" actual diameter) |
| Capacity | 2,500 gallons |
| Service Flow Rate | 0.5 GPM (1.9 LPM) |
| Pressure Rating | 125 PSI maximum |
| Temperature Range | 30–100°F (2–38°C) |
| Chlorine Reduction | >95% |
| Certifications | NSF/ANSI Standard 42 for taste, odor, and chlorine |
Applications & Interchangeability
The K5628 installs in standard RO pre-filtration stages, inline before drinking fountains, under counters ahead of point-of-use taps, and upstream of ice machines. The T40 carbon media is interchangeable with Omnipure T28 and T33 models, offering flexibility when matching flow rate or contact time to specific equipment. Threaded fittings require Teflon tape for installation, and new cartridges should be flushed with 5 gallons of water before service. Replace when rated capacity is reached or when flow rate becomes insufficient. Install in compliance with state and local plumbing codes.
