About Bo Haze

We are an independent affiliate site about air purifiers and PM2.5 monitors, written for shoppers in Singapore. We pull current listings from AliExpress, filter them to ones that ship to Singapore, and show prices in S$.

How we rank. Lists are ordered by recent order counts. That tells you what people are buying, not what is best, so every product comes with a plain-English write-up of what to check.

What we do not do. We do not claim to have tested every product. Write-ups come from listing details and general know-how, and we say so on each page. We leave out ozone generators, replacement filters and wearable gadgets.

Haze data. The live PSI and PM2.5 readings come from NEA via data.gov.sg. For official advice, see haze.gov.sg.

How we make money. Buy buttons are affiliate links. If you purchase, we may earn a commission at no extra cost to you. Details on our disclosure page.
