The EcoAir Crystal MK2 is a 9000 BTU portable air conditioner UK buyers pick when they want smart WiFi control alongside genuine cooling power. Rated A for energy efficiency, it cools, dehumidifies and runs as a fan, covering rooms up to 26m² from a 2.7 kW cooling capacity while drawing only around 1.1 kW. That means a running cost of roughly 29p per hour at the typical 26p/kWh UK rate. Being a true monobloc unit it isn't hoseless: it vents hot air through its supplied exhaust hose to a window, and a free window seal kit is included to block warm air sneaking back in. WiFi control lets you adjust it from your phone, backed by a wireless remote, LED panel, three fan speeds, auto fan mode and a 1-24 hour timer with memory function. Noise runs at 48, 50 or 53 dB(A) across the three speeds, with a dedicated sleep mode for quieter nights. A washable mesh filter traps dust, castor wheels make it easy to reposition, and self-diagnosis plus auto restart keep things reliable. Supplied with the unit, remote, window seal kit and exhaust hose, this certified refurbished model is a smart, efficient way to cool larger UK rooms.

It needs venting and is not hoseless. As a true portable air conditioner it expels hot air through its supplied exhaust hose to a window, and a free window seal kit is included to stop warm air coming back in.
What room size does the 9000 BTU Crystal MK2 cover?
Its 2.7 kW (9000 BTU) cooling output covers rooms up to 26m², suiting larger bedrooms, living rooms and home offices.
How much does the Crystal MK2 cost to run per hour?
It's A-rated and draws around 1.1 kW in cooling mode, so at the typical UK rate of around 26p/kWh it costs roughly 29p per hour to run.
Can I control the Crystal MK2 from my phone?
Yes. It offers WiFi control so you can adjust settings from your phone, alongside a wireless remote, LED panel, three fan speeds, auto fan mode and a 1-24 hour timer with memory function.
Is the Crystal MK2 quiet enough for a bedroom?
It runs at 48, 50 or 53 dB(A) depending on fan speed, with a dedicated sleep mode for quieter night-time operation. On its lowest setting it's reasonable for a bedroom, though fans are quieter if noise is your priority.
