New air purifiers highlight cleaning efficiency

Makers are optimizing cleaning capability with the incorporation multistage filtration systems, ionizers and germicidal lamps.


  • Value-added features: Negative-ion generators and UV germicidal lamps are often incorporated to boost cleaning capability. Many of the latest releases also come with wide-angle oscillation, silent operation, night light, time display and remote control. A number of high-end purifiers adopt Japan sensors that detect the volume of air particles, adjusting the fan strength automatically.
  • Multistage filtration systems: Mainstream models have at least two or three filters for enhanced purification. Makers typically employ charcoal, HEPA, UPLA, photocatalystic, activated carbon or electrostatic precipitator types. The combination of these air-cleaning technologies enables units to remove as much as 99.9 percent of particulates 0.1μm or larger.
  • Coverage area: Basic models are generally suitable for 5 to 15sqm spaces, while midrange designs can be utilized in areas between 15 and 40sqm. Upscale versions have 40 to 70sqm effective range.
