T800

For 15m² next to your computer, grab the **Levoit Core 300S**. Super quiet (22dB sleep mode), compact, has app and auto mode . **Winix T500** is also solid but a bit bigger. Xiaomi 4 is okay but not as quiet . I'd go Levoit. Here's a [**list**](https://medium.com/@dejan-k/best-air-purifiers-under-200-in-2026-360060a1cdf4) if you wanna compare.

Cylinder shaped air purifiers are generally well regarded for small rooms due to their 360 degree airflow, compact footprint, and efficient particulate removal. I myself use Mi Air Purifier 4 for my small bedroom. The Winix T500 you have mentioned have 4 stage filtration system (pre-filter, carbon, true HEPA, and PlasmaWave), quiet operation, and smart features like auto and sleep modes. It removes 99.99% of particles as small as 0.1 microns, and includes WiFi/app control for convenience. It is a good option.

Okay... you STILL haven't told me where you're located, so I have to guess here. But something very oversized would be the Winix T800 WiFi or Winix 5500-2 if you're in Europe. Keep in mind most Winix units have PlasmaWave, a bipolar ionizer. If there are pet birds in your home, keep this *off* as it could harm or kill them. (NB: PlasmaWave is enabled by default after a power off/power on cycle.)
