    CompoCloset™ filtered ventilation accessory

    CompoCloset™ | Cuddy & Cuddy Lite — Externally Venting Carbon Filter

    A replacement ventilation module that filters toilet air before exhausting it through the rear outlet.

    The unit replaces the standard internal filter and fan arrangement and combines particulate filtration with activated carbon to help control odour and excess moisture.

    How it works

    Filter the air before it leaves the toilet

    • Replaces the compatible standard fan and filter arrangement.
    • Uses two HEPA filtration stages.
    • Uses activated carbon for odour filtration.
    • Directs filtered air through the rear exhaust outlet.
    • Helps reduce excess moisture accumulation around the toilet.
    • Provides an alternative filtered exhaust configuration where a conventional wall penetration is not being used.
    Compatibility: confirm the installed Cuddy or Cuddy Lite ventilation configuration before ordering this replacement / alternative filter assembly.
