Full guide: how to choose an air purifier for haze →

Haze sizing follows AHAM's smoke rule — a CADR matching the room's full area in sq ft, not the two-thirds used for ordinary dust — worked from the particle CADR in the seller's listing, so it runs generous. Prices are from Shopee at the time of the last update and may have changed. Monthly figures are Shopee SPayLater over 6 months, including its 1.25% processing fee and rounded up. Subject to approval; a RM10 late fee applies.
