Filtration & Purity: LG Under Sink Water Purifier vs Cuckoo ACE

LG Under Sink Water Purifier

  • Uses a multi-stage “All Puri Filter” system combining Pre-Carbon Block+, ultrafiltration (UF) barriers, and internal auto-sanitization cycles.
  • Tankless flow ensures each glass is freshly filtered — no stored water risk.
  • Hourly sterilization cycles help prevent microbial buildup.

Cuckoo ACE Under Sink

  • Applies a 5-stage filtration including Composite Carbon + Nano Positive Plus 3.0 modules.
  • Features steam faucet sterilization and auto electrolysis cleaning for internal pipes.
  • Also tankless (direct flow), reducing tank storage risks.

Conclusion: Both units aim high in purity, but LG Under Sink Water Purifier‘s automated sanitization paired with tankless design gives you an advantage in low-maintenance microbial defense.

Ease of Use & Daily Handling

LG Under Sink Water Purifier

  • Preset hot temperatures (85°, 75°, 40 °C), ambient, and cold — selectable with one touch.
  • Volume presets (120 / 250 / 500 mL) let you dispense precise amounts.
  • LED / display indicators and filter change alerts.
  • Streamlined faucet interface with minimal buttons.

Cuckoo ACE

  • One-touch interface and jog dial for temperature and volume.
  • Display and controls on faucet, voice guidance and sensor lighting.
  • Steam faucet sterilization button adds extra step.

Conclusion: LG Under Sink Water Purifier leans toward minimal, intuitive operation. ACE gives extra control but more complexity on the faucet interface.

Temperature & Performance

LG Under Sink Water Purifier

  • Hot (preset temps), cold, ambient — good balance for daily hot water and beverages.
  • Direct flow (no tank) means instant dispensing, consistent tempering under typical usage.

Cuckoo ACE

  • Wide range: 5 °C up to 100 °C (boiling/steam).
  • Strong when you need full boiling water on demand.
  • Performance under heavy demand depends on internal heating efficiency.

Conclusion: ACE has the niche edge when you need full 100 °C output. For most homes, LG Under Sink Water Purifier‘s temperature presets and instant flow are more than sufficient.

Maintenance & Reliability

LG Under Sink Water Purifier

  • Automatic sanitization reduces need for manual cleaning.
  • Filter change alerts prompt timely servicing.
  • fewer moving sterilization parts to fail.

Cuckoo ACE

  • Steam and electrolysis systems require upkeep, calibration, or repair over time.
  • Filter changes every few months.
  • If sterilization modules break, professional service may be needed.

Conclusion: LG Under Sink Water Purifier offers a more forgiving maintenance profile. ACE demands more vigilance to keep sterilization features working well.

Energy Use & Efficiency

LG Under Sink Water Purifier

  • LG Under Sink Water Purifier uses sanitization and heating cycles selectively; heating only to preset hot temps rather than steaming constantly.

Cuckoo ACE

  • Cuckoo ACE will use more power during steam / 100 °C operations and periodic sterilization cycles.

Conclusion: For regular household usage, LG Under Sink Water Purifier’s system is likely more energy efficient over the long run.
