Aiper 3-Micron Micromesh Filter — Performance & Replacement

Aiper S1 Series

Performance characteristics & replacement guidance

Direct Answer

The S1’s 3-micron filter captures sand, algae spores, and pet dander — 10× finer than a standard 30-micron basket. Clean after every 2–3 sessions; replace every 3–6 months (genuine part FILTER-S1-3M, cross-compatible 2024–2026).

Why 3 microns matters

Pool water contains particles as small as 1 micron — algae spores, mineral crystals, and organic micro-debris. A standard 30-micron basket is effectively transparent to these particles, allowing them to recirculate freely.

30-micron basket → 3-micron mesh 10× finer

The 3-micron micromesh intercepts these fine particles on the first pass, significantly reducing waterborne turbidity and lowering the chemical load required to maintain sanitiser effectiveness throughout the pool.

Filter maintenance schedule

  • After every session Visually inspect for large debris and empty if full.
  • Every 2–3 sessions Remove and rinse under tap water for 60 seconds to dislodge trapped fines.
  • Every 3–6 months Replace with a new FILTER-S1-3M — approximately every 30 rinses.

Recognising a filter past its service life

A degraded filter compromises both water clarity and the robot’s cleaning efficiency. Watch for these telltale signs:

Visual signs Grey or brown tint to the mesh that does not rinse clear, visible holes or tears, and a persistent ‘musty’ odour even after thorough rinsing.
Functional signs Noticeably reduced suction power and visible fine debris remaining on the pool floor after a full cleaning cycle completes.
