Chasing Hyper-fine Filter Basket for Hydro3 / Hydro3S / Hydro4 / Hydro4SE — Ultra-fine Mesh, Top-load Durable Replacement

The Chasing Hyper-fine Filter Basket is a top-load, ultra-fine mesh replacement designed to capture the smallest debris for Hydro3, Hydro3S, Hydro4 and Hydro4SE robotic pool cleaners.

Keep your robotic cleaner running efficiently and your pool water clear with a purpose-built filter basket. This Hyper-fine Filter Basket from Chasing upgrades particle capture with a denser mesh and a convenient top-loading design so you can remove and rinse trapped debris in seconds. Built from reinforced, UV- and chemical-resistant materials, it’s a durable spare or replacement part that helps maintain circulation and prevents larger contaminants from re-entering the pool.

How does this basket improve cleaning performance?

The finer mesh gathers sand, silt, pollen and tiny organic particles that coarser filters miss, reducing cloudiness and improving water clarity between treatments. It slows the return of small debris into the pool while your Hydro robot circulates and scrubs surfaces.

• Ultra-fine fabric traps micron-sized particles for clearer water.
• Top-load access reduces downtime when clearing the basket.
• Precision fit prevents gaps where debris could bypass the filter.

Will it fit my Hydro model and how easy is it to install?

This basket is engineered to fit Chasing Hydro3, Hydro3S, Hydro4 and the Hydro4SE without adapters. Installation and removal use the same top-loading access built into compatible Chasing cleaners, so no specialized tools or disassembly of the unit are needed.

• Direct compatibility with listed Hydro3 and Hydro4 series cleaners.
• Top-loading design: lift, rinse, reinsert — no full disassembly required.
• Secure seating keeps the filter stable during operation.

How do I care for the filter to prevent clogging?

Because the hyper-fine fabric captures very small particles, it needs periodic cleaning to sustain flow and efficiency. Rinse the basket with a hose after each heavy-use session and inspect more often if your pool has high debris levels or algae presence.

• Rinse under running water to remove trapped grit and pollen.
• Check and clear frequently in pools with heavy debris or poor water balance.
• Avoid harsh scrubbing that could damage the fine fabric; replace when worn.

What materials and durability features does it offer?

The filter basket is molded from reinforced plastics and finished with a chemically resistant hyper-fine fabric designed for harsh pool conditions. UV protection and chemical tolerance extend lifespan compared with untreated alternatives, while the construction stands up to repeated removal and rinsing.

• Reinforced plastic frame resists cracking and warping from pool chemicals.
• UV-resistant materials minimize sun degradation for outdoor use.
• Replaceable as a spare part to maintain long-term cleaner performance.

Who is this for: Pool owners who use Chasing Hydro robotic cleaners and want finer particle removal, less frequent manual skimming, and quicker filter maintenance will benefit most. It’s ideal as a replacement for degraded baskets or as a spare to keep on hand for heavy-use periods, seasonal turnovers, or properties with sandy or pollen-prone environments. Note: performance depends on overall water quality — heavily polluted water will clog fine fabric faster, so combine regular pool maintenance with timely filter rinsing for best results.
