Our verdict
The Artcool Mirror leads on looks with its reflective glass fascia and adds LG's UVnano UV-LED to keep the fan clean. Efficiency is only mid-table (A++ cooling, A+ heating) so as a heat pump it is competent rather than class-leading, but it heats and cools quietly with a 19 dB(A) sleep mode. Best chosen when design and smart features matter more than raw running costs.
Good
- Distinctive mirrored design
- Built-in ThinQ Wi-Fi and UVnano
- Quiet 19 dB(A) sleep mode
Watch out
- Lower efficiency than rivals
