AXEON R1 Series Sediment Filter, 5 Micron

Remove 5-Micron and Larger Particulates From Your Water Supply

Sediment in a water supply — rust particles, sand, silt, and debris — can damage downstream equipment including RO membranes, UV systems, chemical injection pumps, and irrigation components. A sediment pre-filter removes these particles before they reach sensitive downstream components, protecting equipment and extending service life.

The AXEON SDF Series 4.5-inch sediment depth filter uses a multi-stage depth filtration design that captures particulates throughout the full depth of the filter cartridge — not just on the surface. This provides higher total holding capacity and a longer service interval between replacements compared to surface-only filtration designs.

Key Features & Benefits

• 5-micron filtration rating — removes particles 5 microns and larger — including rust, sand, silt, and debris — from the water supply.
• Multi-stage depth filtration — captures particles throughout the full depth of the cartridge rather than only at the surface, providing greater holding capacity and longer service life.
• 4.5-inch diameter housing size — fits standard 4.5-inch diameter filter housings used in commercial water treatment systems.
• Standalone or integrated use — installs as a single-stage pre-filter ahead of RO membranes, UV systems, or other treatment equipment, or as one stage within a multi-stage treatment system.
• Protects downstream equipment — removes sediment that would otherwise foul or damage RO membranes, UV quartz sleeves, pump components, and irrigation emitters.

Who Should Use the AXEON SDF 5-Micron Sediment Filter

Grow facilities and water treatment operators who need to remove 5-micron and larger particulates from a water supply ahead of RO membranes, UV disinfection systems, or irrigation equipment — to protect downstream components and extend service life.

Pre-Filter Placement in a Water Treatment Train

In a multi-stage water treatment system, the sediment pre-filter is the first stage — placed before the carbon filter and RO membrane. This ensures that large particles are removed before reaching the carbon media (which can be clogged by sediment) and before the RO membrane (which cannot be physically cleaned once fouled by particulates). Replace the sediment filter per schedule regardless of visible appearance.

Frequently Asked Questions

What micron rating should I use — 5 micron or finer?

5-micron filtration is appropriate as a pre-filter stage ahead of RO membranes and UV systems, where it removes gross sediment without excessive pressure drop. For very high-sediment water, consider a coarser first stage (20–50 micron) followed by a 5-micron stage.

How often should I replace the sediment filter?

Typical service interval is 6–12 months, but replace sooner if water pressure drops noticeably across the filter housing or if the filter is visibly discolored throughout. More frequent replacement is needed for high-sediment source water.

Will this filter remove dissolved solids like chlorine or minerals?

No — sediment filters remove physical particles only. For dissolved compounds like chlorine, chloramines, or dissolved minerals, use an activated carbon filter and/or RO membrane downstream.

Is this filter compatible with all AXEON filter housings?

The 4.5-inch diameter cartridge fits standard 4.5-inch filter housings. Confirm the cartridge length matches your housing before ordering.
