About this product
This is a 4-pack of unbranded air purifiers designed for large rooms, covering areas from 50-120m² (more than 215 sq ft). Each unit features medical-grade True HEPA and Pre-Filter technology, offering a Particulate Matter CADR of 800 m³/h and Formaldehyde CADR of 500 m³/h. Power is supplied via USB, operating at 5-12V~50Hz with less than 18W rated power. The devices are made from ABS material, include 3 speed settings with a quiet 34 dB(A) operation, and can be mounted on doorways, floors, or tabletops.
Our take
If you're looking to equip multiple rooms with basic air purification, this 4-pack offers a functional solution. The medical-grade True HEPA filtration and strong CADR ratings for both particulate matter and formaldehyde are definitely appealing for improving indoor air quality. I appreciate the quiet operation at 34 dB(A), making them suitable for bedrooms or offices, especially with the included nighttime mode. The USB power source is convenient for flexibility in placement, but you'll need to ensure you have suitable adapters. While effective for odor and smoke, the unbranded nature and ABS material suggest a focus on utility over premium aesthetics or advanced features beyond the core filtration.
