Call For Price



A Towering Achievement in Air CareThe LG AS401WWA1 PuriCare™ Air Purifier is a fresh take on the familiar tower-style air purifier. It can operate as quietly as 20 decibels in low mode and features a highly effective three-stage filtration system: a washable pre-filter, the PuriCare™ micro particle filter, plus a deodorizing filter to reduce unpleasant smells, volatile organic compounds and formaldehyde. The convenient top-mounted display panel features a smart color-coded air-quality indicator, while the small footprint assures it’s never in the way. Now fresh, healthful air is more convenient than ever.
  • The Smart LED indicator system changes from red to green as the indoor air quality improves, for air purification you can see.
  • LoDecibel™ Quiet Operation for whisper-quiet sound levels as low as 23dB (sleep mode).
  • Intelligent Auto Mode fan setting adjusts its purification power based on the current air quality to ensure clean air, while extending filter life and helping save energy.
  • The PM 1.0 micro particle sensor detects contaminants one micron or less in diameter (≤ PM1), for more efficient filtration. 
  • A 3-stage filteration system provides a thorough clean. The washable permanent pre-filter removes large particles like pet dander and dust. Odor and VOC Filter reduces odor, harmful organic compounds and Formaldehyde. And the PuriCare™ micro particle filter traps 99.9% of particles as small as 0.3 microns. These three separate filters work together to deliver purer, cleaner air than any single-filter solution. Filters are color-coded for quick identification and easy replacement.
  • The award-winning PuriCare™ air purifier blends in elegantly with any décor.
  • The inverter motor is so well-designed and dependable, it includes a ten-year warranty on parts.
  • A gentle tone alerts you when it’s time for filter cleaning or replacement.
  • This purifier includes an effective two-touch child lock that deactivates the controls, to prevent accidental setting adjustments.
