10 Best Room Air Conditioners 2025 in the UK

The Pro Breeze 4-in-1 Air Cooler is a portable evaporative cooler designed mainly for homes or offices in dry climates. It uses a 10-liter water tank with included ice packs to cool air through evaporation, which can also add moisture to the air—great if you face dry heat. It offers 3 fan speeds and multiple modes, including a quiet night mode and a 7.5-hour timer, all controllable via remote, making it convenient to use. The unit is easy to move around thanks to its wheels and has a compact freestanding design. It runs quietly at 58 dB, which is about the noise level of a normal conversation, so it won’t be too disruptive. However, unlike traditional air conditioners, it doesn’t have a BTU rating since it cools differently, relying on evaporation rather than refrigerant. This means it works best in lower humidity and might be less effective in very humid areas.

Its energy consumption is low, making it budget-friendly and environmentally friendly compared to standard AC units. The lack of a fixed installation means it’s not a replacement for built-in air conditioning but a flexible, portable option. For those seeking a simple, energy-saving cooler that humidifies and cools moderately, this is a suitable choice. However, if powerful, consistent cold air is required regardless of humidity, a conventional AC might be a better option.

The Pro Breeze 4-in-1 Portable Air Conditioner offers a robust 9000 BTU cooling capacity, making it suitable for medium to large spaces like living rooms, bedrooms, and offices. Its effective cooling can bring temperatures down to 16°C, which is quite efficient for its class. This unit also comes with smart home capabilities, allowing you to control it through a smartphone app or voice commands via Amazon Alexa and Google Home. It provides versatile functionality with four operating modes - air cooling, dehumidifying, fan-only, and sleep modes - all manageable via a digital display or remote control.

Energy efficiency is a notable strength here, with a Class A rating ensuring it’s gentle on your energy bills. The unit uses R290 refrigerant, touted as significantly more eco-friendly than conventional options, appealing to environmentally conscious users. Installation is straightforward with included window venting kits designed for both slide and hinged windows, and its compact design ensures minimal space intrusion.

On the downside, the noise level sits at 54 dB, which might be noticeable in quieter environments. While it’s portable, weighing 24.5 kg, it could be cumbersome to move frequently. Additionally, its Smart Home features depend on WiFi connectivity, which could limit usage in areas with poor internet access. The Seasonal Energy Efficiency Ratio (SEER) is on the lower side at 2.6, indicating room for improvement in efficiency across varying temperatures. This air conditioner is ideal for users seeking a compact, smart, and energy-efficient cooling solution with multiple functions. However, those sensitive to noise or requiring frequent repositioning might want to consider these factors before purchasing.
