What to know before buying

Listing details to confirm

Listing details are inconsistent: the title claims H13 HEPA, while the technical filter field says “Multi-function Hepa Filter”. Room coverage is stated as 2300 sq ft, but the claimed up-to-three air changes per hour has no accompanying CADR or room-height detail. The 22 dB noise figure is specifically attributed to sleep mode, not all settings. Check the selected listing and filter replacement compatibility before buying.

Who is it for?

A good fit for

Buyers seeking an air purifier with a PM2.5 display, auto mode and touch controls.
Homes with pets or concerns about dust, pollen, smoke and odours, based on the listed filtration targets.
People who want a sleep mode, child lock, timer and aromatherapy pad.

Less suited to

Buyers who need a substantiated CADR or independently verified room-coverage performance.
Buyers who require confirmation that the supplied filter meets a specific H13 standard.
