## Description

From the manufacturer

Review: Compact, dead silent, and brilliant for allergies - We got this for the bedroom and it has made a huge difference to the air quality. It is a very compact machine, so it doesn't take up much space, and the fabric pre-filter actually looks quite nice in the room rather than looking like an ugly piece of medical equipment. The performance is fantastic. It clears up dust, pollen, and pet dander quickly, and the smart WiFi features are brilliant. The app lets you see your real-time air quality, tracks trends over time, and lets you control it from your phone without getting out of bed. On its lowest setting, it is completely silent, making it perfect to leave running overnight while you sleep. It does get a bit loud on the maximum setting when it detects a spike in pollution (like cooking smoke), but it clears the air so fast it rarely needs to run on high for long. If you want a smart, fuss-free purifier for a bedroom or a smaller living space, this is easily one of the best on the market. Great little machine.
Review: Great air purifier - Our second purchase of this model. Looks good. The app is easy to use. It's on in the bedroom all night, every night, and the first one we had lasted a few years. The air feels cleaner and according to the app the air is consistently 'excellent'. It's quiet on fan speed 1, some might find it a bit loud on fan speed 2 but you get used to the sound. Definitely helps with hayfever symptoms resulting in a better quality of sleep. Also good for removing cat dander from the air. The genuine filters are a bit pricy but they last a long time.

### ⭐⭐⭐⭐⭐ Compact, dead silent, and brilliant for allergies

### ⭐⭐⭐⭐⭐ A serious air purifier that actually works
*by F***. on 22 December 2025*

Easily one of my best purchases of 2025. After using it for a short time, it genuinely makes you wonder how you ever lived without an air purifier. The air quality improvement is noticeable, especially in a bedroom environment. The room feels fresher and less stuffy, and it has helped significantly with dust and general air cleanliness. The app functionality is excellent, simple to set up, responsive, and useful for monitoring air quality and adjusting settings remotely. The unit itself is fairly large, but this clearly comes down to the size of the filter, which inspires confidence rather than being a negative. It feels well built and designed to handle larger rooms properly rather than being underpowered. Noise levels are impressively low. Even when running continuously overnight, it is quiet enough not to disturb sleep, which was a major deciding factor for me. Overall, a very effective, well designed air purifier that delivers exactly what it promises. Highly recommended for anyone considering improving their indoor air quality.
