Full Review
The De'Longhi Pinguino EX100 Silent is the quietest portable air conditioner we've reviewed at 44 dB. The dual-hose system makes it genuinely efficient — it doesn't draw warm air back in from outside like single-hose models. The A+ rating means lower bills over a long summer. Real Feel technology monitors both temperature and humidity, adjusting output for genuine comfort rather than just cold air. The design is premium and suits modern UK interiors. The price is high, but for a master bedroom or home office where noise and efficiency matter, it's worth the investment.
