1. De'Longhi Pinguino PACAN112 — Best Overall

De'Longhi Pinguino PACAN112
Best Overall 4.8/5

The De'Longhi Pinguino has been Europe's best-selling portable air conditioner for over a decade. The 12,000 BTU (3.5 kW) cooling capacity handles rooms up to 30 m². Three-in-one function: cooling, fan, and dehumidifier — useful across all seasons. At 44 dB on the lowest setting, it's quieter than most competitors at this capacity. 24-hour timer and sleep mode reduce overnight noise and energy consumption.

    • 12,000 BTU — handles rooms up to 30 m²
    • Cooling + fan + dehumidifier in one unit
    • 44 dB — quieter than most competing units
    • Proven reliability — Europe's top seller for a decade
    • ~€450 — mid-premium pricing
    • Single-hose design — less efficient than dual-hose

Window kit installation takes 15–20 minutes and is reusable each season. For most European homes, the Pinguino is the default recommendation for portable AC.

2. Electrolux EXA09 — Best Dual-Hose Efficiency

Electrolux EXA09GL1W dual hose air conditioner

Runner-up ½ 4.6/5

The Electrolux EXA09 uses a dual-hose design — significantly more efficient than single-hose alternatives. While rated at 9,000 BTU, the separate air intake prevents the negative pressure problem that reduces single-hose efficiency. Result: it cools rooms up to 35 m² effectively, more than the rated BTU suggests. Running costs are notably lower than a single-hose unit at the same BTU. Best for heavy summer use.

    • Dual-hose — significantly more efficient operation
    • Effective up to 35 m² despite 9,000 BTU rating
    • Lower running costs than single-hose competitors
    • No negative pressure — room stays comfortable
    • ~€500 — most expensive on this list
    • Two hoses require slightly more complex window kit setup

3. Inventor Fresh 9K — Best Value

Best Value ½ 4.4/5

The Inventor Fresh 9K is the best budget portable air conditioner for smaller rooms. At €320, it's approximately €130 cheaper than the De'Longhi with comparable features for rooms up to 20 m². A-rated energy efficiency keeps running costs reasonable. Cooling, fan mode, and dehumidifier cover all seasonal needs. Inventor is a well-established Greek brand for air conditioning across Southern and Central Europe.

    • ~€320 — best value on this list
    • A-rated energy efficiency
    • Cooling + fan + dehumidifier in one unit
    • Reliable Inventor build quality
    • 9,000 BTU — only suitable for rooms up to 20 m²
    • 48 dB — louder than De'Longhi or Meaco

4. Meaco Cool MC Series — Quietest

Quietest ½ 4.3/5

The Meaco Cool MC is designed specifically for quiet operation. At 40 dB in normal use and 35 dB in sleep mode, it is measurably quieter than the De'Longhi and Electrolux. For bedroom cooling during sleep — especially in apartments where the air conditioner must run overnight — the Meaco's quiet operation is a genuine advantage. 10,000 BTU handles rooms up to 25 m².

    • 40 dB normal / 35 dB sleep mode — quietest available
    • Engineered for bedroom overnight use
    • 10,000 BTU covers rooms up to 25 m²
    • UK brand with strong dehumidifier heritage
    • ~€480 — premium pricing for 10,000 BTU
    • Less capacity than De'Longhi at similar price

5. Dyson Purifier Cool TP09 — Best Air Purifier Combo

Best Purifier Combo 4.1/5

The Dyson Purifier Cool is not a true air conditioner — it uses a fan without a compressor. On hot days below 30°C, a powerful bladeless fan with moving air creates meaningful cooling. Where it excels is year-round air quality: HEPA H13 filtration captures 99.97% of particles as small as 0.1 microns — pollen, dust, bacteria, mould spores. Dyson Link app monitors room air quality in real time. Best for allergy sufferers who need both cooling and filtration.

    • HEPA H13 — captures 99.97% of particles including pollen
    • Dyson Link app — real-time air quality monitoring
    • Bladeless design — safe and easy to clean
    • Year-round use as both fan and purifier
    • Not a true AC — won't cool above 30°C effectively
    • ~€550 — most expensive for limited cooling power

How Much Cooling Power Do You Need?

BTU sizing guide

Up to 20 m²: 7,000–9,000 BTU. 20–30 m²: 10,000–12,000 BTU. 30–40 m²: 12,000–14,000 BTU. Single-hose units are inherently less efficient than their BTU rating suggests — they draw warm air from the room to exhaust heat, creating negative pressure that pulls more warm air in. Dual-hose units (Electrolux EXA09) are significantly more efficient at the same BTU rating.

Running costs

A 10,000 BTU unit consumes approximately 1.5–2 kW per hour. At average European electricity prices (~€0.25/kWh), running the unit 8 hours per day costs approximately €3–4 per day — approximately €180–240 over a typical European summer.

Our Verdict

The De'Longhi Pinguino PACAN112 is the best all-round portable air conditioner for most homes — proven reliability, good cooling, and reasonable noise. For maximum efficiency (particularly in rooms you cool heavily), invest in the dual-hose Electrolux EXA09. For bedroom sleeping comfort, the Meaco Cool MC is quietest.

Frequently Asked Questions

Portable or split air conditioner — which should I buy?

Portable (De'Longhi Pinguino PACAN112, Electrolux EXA09GL1W): no installation, can move between rooms, easy to store off-season. Less efficient, louder. Split system: fixed installation, more efficient (cheaper to run), quieter, more powerful. For renters or occasional cooling: portable. For homeowners with regular need: split AC (professional installation, £1500-3000).

What BTU rating do I need?

10m² (small bedroom): 5000-7000 BTU. 20m² (standard bedroom): 9000-12000 BTU (Inventor Fresh 9K). 30m² (living room): 12000-15000 BTU (De'Longhi Pinguino PACAN112). Larger spaces: 18000+ BTU. Always size up rather than down — undersized AC runs constantly without ever cooling effectively. South-facing rooms need more BTU than north-facing.

Inverter or fixed-speed AC?

Inverter (modern models): variable speed compressor that ramps up and down as needed — much more energy efficient and quieter than fixed-speed. The Electrolux EXA09GL1W and modern De'Longhi Pinguino use inverter technology. Fixed-speed compressors only on/off (loud cycling). For 2026 buyers: inverter is standard on premium models, worth the £100-200 premium.

How efficient are portable air conditioners?

Less efficient than split systems. Portable AC efficiency is rated by EER (Energy Efficiency Ratio) or SEER (Seasonal). Look for EER 9+ or SEER 12+. The De'Longhi Pinguino PACAN112 has EER of 11+. Hot exhaust must be vented through window — a poorly fitted vent loses efficiency. Modern portable AC is 30-50% less efficient than equivalent split AC but installs in minutes.
