The verdict
A top-performing, whisper-quiet air purifier that prioritizes cleaning power and design over smart features, ideal for those who want simplicity and effectiveness.
Read the full reviewWhat we love
- +Exceptional air cleaning performance in its class, with high CADR ratings for smoke, dust, and pollen.
- +Very quiet operation, especially on lower fan speeds, making it suitable for bedrooms.
- +Energy efficient, consuming low power and having an Energy Star certification.
- +Stylish, minimalist design with a fabric cover that also acts as a pre-filter.
Worth noting
- –No app connectivity or smart features, which some competitors offer.
- –Lacks a manual filter replacement indicator; relies on a built-in timer that may not accurately reflect actual filter life.
- –Filter replacement cost is higher over time compared to some rivals.
- –No additional modes like auto or sleep mode; only manual fan speed control.
