We have compared these two solutions based on 8 criteria detailed below to help you choose the one that best fits your needs.<\/span><\/h4>\n

    1. Noise Level<\/strong><\/span><\/h3>\n

    A quick note: noise doubles every 3 decibels dB(A) (see our noise\/silence article)<\/span><\/p>\n

     <\/p>\n

    Air Conditioner:<\/b><\/h5>\n

    Portable single-block air conditioners are very noisy (at least 50 dB(A), equivalent to a running washing machine) because the entire mechanism is inside the room. Split systems have an external unit that handles the loudest and hottest tasks to minimize indoor discomfort.<\/span><\/p>\n

    Be aware that laws often define a “tolerable” threshold for neighbors: adding equipment must not increase noise by more than 5 dB(A) during the day and 3 dB(A) at night (<\/span>Article R. 1334-33 of the public health code<\/span><\/a>). The noise level of an external AC unit is at least <\/span>45 dB(A)<\/span><\/a>.<\/span><\/p>\n

    Also, be cautious of manufacturers claiming “noise levels” around 20 dB(A) to suggest near-silence. A closer look at technical sheets reveals this figure often refers to <\/span>acoustic pressure<\/span><\/i> without further context.<\/span><\/p>\n

    Acoustic pressure is measured at a specific distance, while acoustic power is measured directly on the product.<\/span><\/p>\n

    Therefore, beware of acoustic pressure values that are not associated with a distance.<\/span><\/p>\n

    The only real recommendation is to hear the product in person.<\/span><\/p>\n

     <\/p>\n

    Fan:<\/b><\/h5>\n

    The noise generated by fans varies by “morphology”: the fewer blades a propeller has, the faster it must spin, and the faster it spins, the more audible vibrations it creates. Similarly, a smaller propeller diameter requires higher speeds, increasing noise.<\/span><\/p>\n

    It’s worth noting that so-called “bladeless” fans actually have a small-diameter propeller hidden in the base that spins very fast. This explains the high noise level of these models. You will often find that these manufacturers only compare their noise levels to their own older products.<\/span><\/p>\n

    Grilles and other mechanical supports in the airflow also contribute to noise. Plastic grilles are noisier than metal ones due to their larger surface area; radial grilles are noisier than annular ones because they obstruct the central airflow. Sound power is proportional to the ventilation power; thus, the more speed settings a fan has, the better you can adjust the noise level. Top-performing fans can approach 40 dB(A), while poor models exceed 70 dB(A).<\/span><\/p>\n

    Williwaw:<\/b><\/h5>\n

    Williwaw is THE silent fan:<\/span><\/p>\n

    At low power, it emits only 33 dB(A), which is imperceptible even in a quiet room\u2014ideal for sleeping or focusing at the office.<\/span><\/p>\n

    At full power, it emits 47 dB(A), making it 4 times quieter than bladeless fans while delivering twice the airflow.<\/span><\/p>\n

    Williwaw’s silent performance is the result of advanced engineering: a 9-blade propeller to reduce rotation speed, a digital motor for precise speed control, spiral grilles to minimize obstruction, and teardrop-shaped optimization on all mechanical supports within the airflow.<\/span><\/p>\n

    2. Practicality:<\/b><\/span><\/h3>\n
    Air Conditioner:<\/b><\/h5>\n

    To create cold, you unfortunately have to create heat. This heat must be evacuated, either via an external unit or a hose connected to the outside.<\/span><\/p>\n

    Environmentally, the impact on outdoor temperatures is direct:<\/span><\/p>\n

    \u201c<\/span>If every Parisian household equipped themselves with air conditioning, average electricity consumption during heatwaves would double, increasing street temperatures by 3\u00b0C compared to a city with no air conditioning systems<\/span><\/i>.\u201d<\/span> Environmental Research Letters<\/span><\/a><\/p><\/blockquote>\n

    Because it acts on the total air mass of the room, an air conditioner has a significant latency period, leading to several issues:<\/span><\/p>\n
