## Description

From the manufacturer

Review: A serious air purifier that actually works - 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.
Review: Seems OK one month in and is quiet to use - Seems ok, and phone app is useful. I've been using this for approx one month now and the phone app connected to this device is super useful to check on the current 'air quality' level as well as viewing how much of the filter is 'left' until it is recommended to be changed. My air quality is generally good or excellent on most days, and there is still (after one full month, 90% left) of my filter for use. So, it isn't working hard and you can probably get 10 months or 12 (if you push it) per year with each filter. Operationally, usage is very quiet, which is solid plus.
