Reviews last updated: August 2026 · How we calculate this

What we like about MELEDEN 900s

  • Noticeably improves indoor air quality and room freshness
  • Effectively reduces pet dander, allergens, dust, and smoking odors
  • Compact, lightweight, and space-saving desktop design
  • Quiet overall operation, making it suitable for night use in bedrooms
  • Features a soft, non-intrusive built-in blue LED night light
  • Simple one-touch operation with a built-in 8-hour auto-shutoff timer

What we don't like about MELEDEN 900s

  • Replacement filters can be relatively expensive to purchase regularly
  • Lacks internal fan speed adjustments or precise mode control
  • Does not include a wall adapter plug, only providing a micro-USB cable
  • Limited coverage area that takes a few hours to clean larger rooms
  • Short overall hardware lifespan reported by some users

Verdict

The MELEDEN 900s is a corded-electric desktop air purifier designed for small rooms, bedrooms, and offices, covering an effective floor area up to 80 square feet (approx. 7.4 square metres) with a clean air delivery rate (CADR) of 50–75 m³/h. Weighing 0.6 kilograms and measuring 20 x 12.5 x 12.5 centimetres, it features an imported True HEPA filter that captures 99.97% of airborne dust, pollen, pet dander, and smoke particles down to 0.3 microns without releasing harmful ozone. Its main advantages include a touch-control panel, whisper-quiet operation at 32 decibels, power-saving efficiency, an 8-hour automatic timer, and a gentle, dimmable ambient light suitable for sleep mode. However, a notable disadvantage is that it comes only with a USB power cable and lacks the required wall charger/adapter plug in the box.
