R290 eco refrigerant — GB compliant

Ultra-low global-warming refrigerant, legal for portable use in Great Britain.

The Costway 9000 BTU 3-in-1 portable air conditioner pairs strong cooling with eco credentials, using R290 refrigerant for a lower environmental footprint than older blends. With 9000 BTU it cools rooms up to 20m², a good match for bedrooms, apartments, basements and offices, and its 24 L/day dehumidifier mode is one of the stronger in its class for tackling damp and humidity. A two-speed fan mode rounds out the trio so it stays useful outside heatwaves. Rated at 1005W in cooling, it costs roughly 26p an hour at 26p/kWh. At ≤65 dB on full it's audible, suiting living and work spaces, with a quiet sleep mode for calmer nights. Being a single-hose monobloc it must be vented through a window using the supplied exhaust hose and window kit, so it is not a hoseless unit. A removable, washable filter screen keeps air clean, and a child lock plus 24-hour timer add convenience. Control comes via remote, touch panel or LED display. At 21kg with casters and built-in handles it's easy to relocate. The box includes the AC, exhaust hose, exhaust water pipe, hose connector, window kit, remote and instruction manual.
