Why are air purifier searches increasing in Singapore?
Singapore is facing its longest period of unhealthy air quality since September, with PSI levels exceeding 101 since Oct 5 [1]. This has caused a spike in demand for air purifiers, with some retailers reporting sales increases of over 76% [3].

What you need to know
HEPA filters are designed to capture tiny haze particles like PM2.5 [1].
Standard home air-conditioners generally cannot filter out fine particulate matter [1].
Buyers should check the Clean Air Delivery Rate (CADR) and recommended room size [2, 3].
Indoor plants are generally ineffective at removing fine haze particles [1].
It is not confirmed how long the current stretch of unhealthy air quality will last.
Background
The current air quality issues are driven by transboundary haze, specifically PM2.5 particles. These particles are 30 times smaller than a human hair and can enter the bloodstream or lodge in the lungs [1].
Singapore uses the Pollutant Standards Index (PSI) to report air quality. This index is based on six pollutants, including ozone, carbon monoxide, and particulate matter [1].
Questions people ask
Can my air-con filter the haze?
Most home air-con filters only catch large dust and are not efficient at removing fine particles, though closing windows while using them helps keep haze out [1].
Do indoor plants help with haze?
While they can absorb some gaseous pollutants, they lack the surface area to meaningfully filter fine particulate matter [1].
