Frequently asked questions
Are air purifiers under S$30 any good?
Often yes for one bedroom or a desk, as long as the listing states a real HEPA grade, a CADR or coverage figure and recent reviews are positive. The cheapest units usually cut corners on filter life, noise and build quality, so read the latest reviews before paying.
Do these prices include GST and delivery?
Prices are from AliExpress at the time of the last update. GST and delivery are confirmed at checkout, so check the final amount before you pay.
