Best picks
Bonaire Duet 6L is our compact-room pick; Bonaire Diet 12i suits a room needing more tank capacity, while Dimplex DCEVP6BW adds tower controls and a remote.
Quick answer
Bonaire Duet 6L is the compact pick, with manufacturer guidance for spaces up to 27 m³. Consider the Diet 12i for a 12-litre tank and remote, or the Dimplex DCEVP6BW if you want a tower format with a remote and several operating modes.

Best for compact rooms
Drawback: Bonaire’s stated coverage is room volume, so compare it with your room dimensions rather than floor area alone.
Official manufacturer image
Best for a larger tank with remote
Drawback: The product page gives no room-volume figure in its technical details.
Official manufacturer image
Best for a medium-sized room
Drawback: Its larger tank and body take more floor space than the Duet.
Best for tower-style controls
Drawback: Dimplex lists a 20 m² maximum room size; that guidance may not match every room or climate.
Best for a cooler with a stated purifier mode
Drawback: Its purifier room guidance is separate from the cooler room guidance; it is not a substitute for choosing a cooler by airflow needs.

Common questions
Bonaire specifies the Duet 6L for rooms up to 27 m³, making its stated use the clearest compact-room match in this selection. Check your room volume and allow for local humidity and ventilation.
An evaporative cooler uses water evaporation and airflow; a portable air conditioner uses refrigeration and normally needs exhaust venting. The suitable type depends on your climate, room and installation options.
Their cooling effect depends on evaporation, so high humidity can reduce the effect. Check the manufacturer’s guidance and consider ventilation and local conditions before buying.
It depends on tank capacity, fan setting and operating conditions. A larger tank can reduce refill frequency, but the cited product pages do not promise a fixed runtime across settings.
Keep exploring
A portable evaporative cooler suits hot, dry air and a ventilated room; a fan-only unit avoids adding moisture. Start with climate, airflow and cleaning needs.
An evaporative cooler uses water and ventilation; a refrigerated air conditioner uses a compressor and can dehumidify. Climate and the result you need decide between them.
Evaporative air conditioning cools incoming air through water evaporation and needs an exhaust path. Its suitability depends strongly on outdoor humidity and the building layout.
Bonaire Crown 10i is a practical shortlist choice for its published room guidance and portable design. Bonaire Duet suits a smaller spot; Dimplex DCEVP6WT adds a purifier function.
