CUCKOO Built-In Purifier

Built-in under-sink purification with instant hot water and a cleaner kitchen footprint

The CP-AAN100UL brings filtered water, instant hot water, and refined everyday usability into one sleek under-sink system. The main unit stays tucked below the counter while only a slim faucet remains visible, helping create a cleaner, more open kitchen look without giving up convenience.

Designed for daily drinking, cooking, and prep, this model combines temperature control, touch operation, automatic cleaning support, and shopper-friendly maintenance in a layout that feels premium and practical at the same time.

Why Shoppers Choose It

Minimal built-in designLeaves only a slim faucet above the sink while the main unit stays hidden below for a cleaner, more spacious kitchen.
Instant hot water up to 100°CSelect hot water from 40°C to 100°C without waiting to boil water separately.
Touch LCD and jog dialChoose temperature and water volume quickly through an intuitive touch display and dial control.
No storage tankDelivers temperature-controlled water without the bulk of a traditional storage tank.

Feature Details

  • Auto cleaning from the outlet to the water pipes: Electrolysis cleaning helps keep the faucet path and water lines fresh for everyday use.
  • One faucet for drinking and cleaning: Switch between drinking water and cleaning use from a single outlet for added flexibility around the sink.
  • Motion sensor welcome light: The light turns on when someone approaches and shifts into power-saving mode when no motion is detected.
  • Easy filter replacement: Open the filter cover, replace the cartridge, and close it back up with minimal hassle.
  • Simple operation: The modern control layout is designed for fast, straightforward day-to-day use.

Known For

Known for premium built-in installation, hidden under-sink layout, and instant 100°C performance. Its price is shaped by a more integrated kitchen setup and stronger hot-water control than standard countertop models, while staying focused on streamlined built-in convenience rather than the ice-making or heavier shared-space output of CUCKOO's top freestanding systems.

Good Fit For

Shoppers who want a premium under-sink purifier with instant hot water, a cleaner visual setup, and easier temperature-controlled access for tea, coffee, cooking, and everyday hydration.

Installation: Third-party installation is required. After purchase, installation may be arranged through a certified technician when available in your area.

Manuals, Guides & Videos

Review the included product manual before installation and first use. For help confirming under-sink placement, faucet location, water-line connection needs, filter service, or temperature-control operation, contact us before checkout.

  • Included guides: Product manual, built-in installation guidance, faucet setup, startup flushing instructions, touch LCD and jog dial use, auto-cleaning guidance, and filter-care steps.
  • Setup planning: Confirm under-sink clearance, water-line access, electrical outlet placement, faucet-hole requirements, and room for routine filter replacement.
  • Video help: Watch Cuckoo America product and care videos on YouTube.
