Lidl’s €149 Air Conditioner: Is It a Lifesaver in Europe’s Heatwave? Expert Weighs In
Berlin, Germany – July 16, 2025 – As temperatures soar across Europe, particularly impacting those on higher floors, discount retailer Lidl has launched a new mobile air conditioning unit, the SMK 7000 B2, priced at €149. But with rising energy costs and concerns about indoor air quality, is a portable AC unit a smart investment? archyde.com dives into the details, speaking with energy experts to help you stay cool and informed.
Lidl’s new SMK 7000 B2 mobile air conditioner aims to provide relief from the heat.
The Heat is On: Why Higher Floors Suffer Most
Summer 2025 is proving to be a scorcher, and the effects are amplified on upper levels of buildings. Solar radiation, coupled with a lack of natural cooling, creates a “heat trap” effect. Beyond the discomfort, increasing UV radiation poses a direct health risk. This has prompted many to seek solutions for indoor climate control, and Lidl’s offering is stepping into a market ripe with demand.
Two Types of Mobile Cooling: What’s the Difference?
Not all mobile air conditioners are created equal. Experts distinguish between air coolers and true air conditioners. Air coolers, often cheaper, rely on water evaporation to lower the temperature – a temporary fix best suited for dry climates. The more effective option is a mobile air conditioner, which dehumidifies the air. This process not only feels cooler but also allows your body to regulate its temperature more efficiently through sweat evaporation.
“The key is dehumidification,” explains Michael Maucher, an energy consultant at the Baden-Württemberg Consumer Center. “Removing moisture from the air makes a significant difference in how comfortable you feel.”
Hose vs. No Hose: Choosing the Right Model
Mobile air conditioners come in two main configurations: those with and without exhaust hoses. Units without a hose primarily dehumidify, offering a subtle cooling effect. Those with a hose vent hot air outside via a flexible pipe, typically through a window. This is the more powerful option, capable of significantly lowering room temperature. However, it requires careful setup to avoid drawing in hot air from outside.
“Pay attention to window placement,” warns Maucher. “Ensure the exhaust hose is properly sealed to prevent hot air from re-entering the room.”
The Two-Hose Advantage: Efficiency and Air Renewal
For even greater efficiency, consider a two-hose model. These units draw in fresh air from outside, reducing pressure imbalances and boosting cooling capacity. This is particularly effective during cooler morning and evening hours when outside air is significantly cooler than indoor temperatures. These models can cool rooms up to 50 cubic meters (approximately 20 square meters), aligning with Lidl’s SMK 7000 B2’s stated capacity of 45 cubic meters.
A Word of Caution: The “Germ Slingshot” Effect
While effective, mobile air conditioners require diligent maintenance. Stagnant water within the unit can become a breeding ground for bacteria and mold, potentially releasing harmful particles into the air. Regular cleaning and emptying of the water reservoir are crucial, especially for allergy sufferers.
“Airflow can circulate dust and allergens,” notes Maucher, “but most modern units, including Lidl’s SMK 7000 B2, are equipped with air filters to mitigate this risk.”
Who Benefits Most from a Mobile Air Conditioner?
Mobile air conditioners aren’t for everyone. They take time – several hours – to cool an entire room, including furniture. However, they offer significant benefits for specific groups. Those working from home, individuals with pre-existing health conditions, or anyone particularly vulnerable to heat stress will find the investment worthwhile. The ability to create a localized cool zone can dramatically improve comfort and well-being.
Don’t forget simple preventative measures: keep blinds and roller shutters closed during peak sunlight hours, and consider utilizing the “heat trick” – cooling a room by strategically opening windows during cooler periods.
As Europe continues to grapple with extreme heat, finding effective and affordable cooling solutions is paramount. Lidl’s new air conditioner offers a potential answer for many, but informed decision-making, proper usage, and regular maintenance are key to maximizing its benefits and minimizing potential risks.
