The noise level of the Winix 5500-2 varies depending on the settings you choose. It has four fan speedsāLow, Medium, High, and Turboāplus an Automatic mode that adjusts based on real-time air quality and a Sleep mode that kicks in when it senses darkness to keep things quiet and dim the lights. Pretty handy for night use, right?
From our research, when it's on Low or Sleep mode, it's super quiet. People often describe it as barely noticeable, or like a gentle white noise. Perfect for bedrooms or nurseries.
On Medium, it's still manageable, more like a soft background hum that blends into the usual household sounds. Not too distracting at all.
Now, if you crank it up to High or Turbo, it does get louder. Think the noise level of a typical fan or an air conditioner. This might be too much for really quiet spaces but works just fine during the day or in larger areas where you need that extra air cleaning power.
In Automatic mode, it adjusts the fan speed based on the air quality. Our data shows that in rooms with stable air quality, it mostly stays on Low or Medium, so the noise isnāt bad at all. But if the air gets polluted, it may switch to High or Turbo briefly, which will increase the noise.
One thing to keep in mind: the automatic shift to Sleep mode can't be turned off. If you'd rather it not switch to Sleep, you'll need to set the fan speed manually, which stops it from adjusting automatically.
Overall, the Winix 5500-2 offers a range of noise levels to fit different settings and needs, making it pretty versatile.
