HydroLogic® smallBoy® Dechlorinator & Sediment Water Filtration System - 1 GPM - 5 Micron - 3,000 Gallon Capacity

Inline Chlorine & Sediment Removal for Cleaner Growing Water, 1 GPM

The HydroLogic® smallBoy® Dechlorinator and Sediment Water Filtration System is a compact, wall-mountable 2-stage water treatment system that removes up to 99% of chlorine and 90%+ of sediment, rust, silt, and volatile organic compounds from tap water — producing 60 gallons per hour of treated water at 1 GPM. With a 3,000-gallon filter capacity per service cycle and a simple garden hose connection, the smallBoy® is a straightforward way to improve tap water quality for indoor growing and hydroponic applications without the cost of a full RO system.

At 1 GPM / 60 GPH, this size is sized for small to medium grow rooms and reservoir filling — growers with larger daily water needs should look at the higher-capacity TALLBoy® system instead.

Key Features & Benefits

• 99% chlorine removal: a carbon block filter removes chlorine from municipal tap water, protecting beneficial microbial populations and improving growing water quality.
• 90%+ sediment reduction: a 5-micron poly-spun sediment filter captures rust, silt, dirt, and particulates to protect downstream irrigation components.
• Removes VOCs to 5 microns for cleaner, safer growing water.
• 1 GPM flow / 60 GPH output: sufficient for small to medium grow room and reservoir filling.
• 3,000-gallon capacity keeps maintenance intervals manageable for small to medium-scale operations.
• Complete installation kit included: 2-stage 10in filter unit, wall-mountable metal bracket, garden hose connector, 4ft feed line, 6ft outlet line, 1/4in shut-off, filter wrench, and instructions.

Who Should Use This

Ideal for hydroponic growers, indoor cultivators, and greenhouse operators who want to improve municipal tap water quality before it enters their growing system, without investing in a full RO setup. Also effective as a dechlorination and sediment pre-filter ahead of a Stealth-RO system.

Compatibility

Replacement sediment filter: smallBoy Poly-Spun Sediment Filter (HGC728885) — Dimensions: 12in x 14in x 6in. KDF/Catalytic Carbon filter upgrade available.

Frequently Asked Questions

Does this system remove chloramines?

The smallBoy system is designed primarily for chlorine removal. For chloramine removal, the KDF85/Catalytic Carbon Filter Upgrade provides more effective chloramine reduction; contact HydroLogic for upgrade options.

How long does the filter capacity last?

The system has a 3,000-gallon per-cycle filter capacity. At the system's rated GPH output, this represents roughly the run time before a filter change is needed, though actual capacity in hours depends on usage patterns.

What is included with the smallBoy?

The smallBoy ships complete with 2-stage 10in filter unit, wall-mountable metal bracket, garden hose connector, 4ft feed line, 6ft outlet line, 1/4in shut-off, filter wrench, and instructions. Every part needed for a standard wall-mounted installation is included in the box.

Can this be used as a pre-filter before an RO system?

Yes — the smallBoy is an effective pre-filter for Stealth-RO systems, removing chlorine and sediment to protect the RO membrane. Running it upstream of an RO system extends membrane service life.

What replacement sediment filter does the smallBoy use?

The smallBoy uses the smallBoy Poly-Spun Sediment Filter (HGC728885) replacement sediment filter, which should be replaced per the system's recommended schedule. Replacing it on schedule keeps sediment reduction performance consistent.
