  • Cooling bedrooms, conservatories, home offices and lofts

  • Reducing humidity and improving indoor air quality

  • Providing consistent temperatures during heatwaves

  • Supporting allergy and asthma sufferers with air filtration

🧠 Expert Tips for Buying & Using Air Conditioners

  • Use blackout blinds or curtains during the day to reduce the cooling load

  • Always vent your portable unit properly to remove warm air

  • Maintain your unit by cleaning or replacing filters regularly
