In detail: Whirlpool PACW212CO, 12000 BTU portable air conditioner
The Whirlpool PACW212CO is a monobloc portable air conditioner built around the manufacturer's 6th Sense technology, which automatically adapts the operating mode to ambient conditions. Its most notable feature remains the Around U function: a temperature sensor built into the remote measures the heat felt right where you actually are, up to 7 metres from the unit, and adjusts cooling accordingly instead of relying solely on the zone close to the air conditioner itself.
Rated by the manufacturer at 3.5 kW (12,000 BTU/h) for rooms of 20 to 30 m², the unit also includes a HEPA filter able to capture particles larger than 0.3 micron, a genuine plus for allergy-prone households, along with automatic vertical swing and an Auto Clean function that limits mould growth inside the unit. Side handles and multi-directional castors make it easier to move between rooms, and the exhaust hose, adjustable from 48 to 177 cm, adapts to different window setups.
An independent test carried out by a consumer body sheds useful light on the unit's real-world performance: measured cooling capacity comes out at 3.1 kW, slightly below the claimed 3.5 kW, and the real energy class observed is B rather than the A declared by Whirlpool. A gap that isn't unique to this model (official manufacturer measurements follow protocols that don't always reflect real-world use), but one worth knowing before comparing on spec sheets alone.
The R290 refrigerant, more environmentally friendly, equips the unit, whose weight of about 37 kg places it among the heavier portable air conditioners in its category. The compressor stays audible at startup, a trait common to nearly all monobloc units. For typical summer cooling use, with a welcome nod to air quality thanks to the HEPA filter, the PACW212CO remains a solid choice backed by the reputation of a major appliance brand.

Comparison
In a comparable price range (£350 to £600), the Whirlpool PACW212CO regularly comes up against the Electrolux ChillFlex Pro EXP26U558CW, another portable air conditioner from a major appliance group, in searches like "Whirlpool vs Electrolux air conditioner". Here is how the two compare, based on the public specifications of both manufacturers.
| Criterion | Whirlpool PACW212CO | Electrolux ChillFlex Pro |
|---|---|---|
| Claimed cooling capacity | 3.5 kW (12,000 BTU/h) | ≈3.1 kW (10,500 BTU/h) |
| Claimed energy class | A | A |
| Distinctive feature | Around U, remote temperature sensor | Dedicated silent mode |
| Noise level | 64 dB(A) | 49 dB(A) in silent mode |
| HEPA filter | Yes | Not specified by the manufacturer |
In short, the Electrolux ChillFlex Pro highlights a dedicated silent mode for night-time use, while the Whirlpool PACW212CO bets on its Around U function and HEPA filter for comfort centred more on the user than on the room alone. The choice mostly comes down to prioritising quiet operation versus smarter thermal regulation.
Our tester's verdict: Christophe Delpuech
The PACW212CO carries a solid review base, with feedback regularly praising a noticeably fresh feel within one to two hours, in 30 m² rooms during peak summer. The Around U function, which adjusts cooling based on the remote's actual position rather than just the zone near the unit, is a genuine differentiator rarely seen at this price point. An independent consumer test, however, offers a more nuanced picture: measured cooling capacity (3.1 kW) and real energy class (B) both fall short of Whirlpool's declared figures (3.5 kW, class A), a gap worth knowing before comparing this model against rivals on spec sheets alone. The compressor stays noisy at startup, much like nearly every monobloc unit, and a poorly supplied manual is the most frequent complaint from buyers, several of whom had to search for instructions online. The HEPA filter is a genuine plus for allergy-prone households. Overall, an honest air conditioner with thoughtful ergonomics (handles, multi-directional castors, self-clean mode), as long as you approach the manufacturer's headline figures with a bit of caution.
