HydroLogic® smallBoy® Poly-Spun Sediment Filter - 10in x 2.5in - 5 Micron - Single Use

5-Micron Pre-Filter for smallBoy System & Membrane Protection

The HydroLogic® smallBoy® Poly-Spun Sediment Filter is a single-use, 5-micron melt-blown polypropylene sediment pre-filter engineered for use with smallBoy® water filtration systems. Capturing silt, rust, dirt, sand, and other suspended solids at a 5-micron level, this filter protects downstream filtration components — including RO pumps and membranes — from particulate damage and premature fouling.

Sized specifically for smallBoy® filter housings, this filter drops in for routine maintenance without any adapters or modifications, giving growers a predictable replacement part to keep on hand.

Key Features & Benefits

• 5-micron melt-blown filtration: melt-blown polypropylene construction provides consistent particle capture throughout the depth of the filter media, not just at the surface.
• Protects downstream components: capturing sediment, rust, silt, and dirt before they reach RO membranes and pumps extends equipment service life.
• System-specific sizing: dimensioned at 10in x 2.5in for correct fitment and seal in smallBoy filter housings.
• Single-use design: not cleanable — replace on schedule to maintain consistent 5-micron filtration performance.

Who Should Use This

Required replacement filter for smallBoy system operators. Consistent sediment pre-filter replacement is essential for maintaining downstream component protection and overall system performance.

Compatibility

For use with: HydroLogic smallBoy systems — Dimensions: 10in x 2.5in — Single use, not cleanable. Replace per system schedule.

Frequently Asked Questions

Can this poly-spun filter be cleaned and reused?

No — poly-spun melt-blown sediment filters are single-use only. Unlike pleated sediment filters, they can't be effectively cleaned, so replace on the recommended schedule to maintain filtration performance.

What is the difference between melt-blown and pleated sediment filters?

Melt-blown polypropylene filters trap particles throughout the depth of the fiber matrix, while pleated filters capture debris primarily on the surface. Depth filtration provides higher dirt-holding capacity for consistent performance over the filter's service life.

What does 5 micron mean?

A 5-micron filter captures particles 5 micrometers (0.005 mm) in diameter and larger. This removes fine silt and rust particles that would otherwise be invisible to the naked eye but can damage precision components.

When should I replace this filter?

Replace this filter per your smallBoy system's recommended schedule, or sooner if you notice reduced flow, since a loaded sediment filter restricts water throughput. Keeping a spare on hand simplifies routine maintenance.
