Reviews last updated: August 2026 · How we calculate this

What we like about ASIGO 90690

  • Filterless design means no recurring costs for filter replacements
  • Extremely quiet or completely silent operation in ionizer mode
  • Easy maintenance by simply wiping down the internal metal plates
  • Effective at reducing odors, kitchen smells, and cigarette smoke
  • Helps alleviate allergy symptoms by capturing dust and pollen
  • Compact and space-saving footprint

What we don't like about ASIGO 90690

  • Lacks active air circulation and has a relatively low airflow rate
  • Not effective at reducing viruses or circulating air rapidly through large spaces
  • Produces low levels of ozone as part of its ionization process
  • Perceived as expensive or offering lower performance value compared to premium HEPA filters

Verdict

The ASIGO 90690 is a filterless air ionizer and purifier designed for rooms up to 20 m², operating via an electrical metal-lamellae insert that releases negative ions to attract and trap airborne pollutants. It features an incredibly quiet, motor-free and fan-free design that effectively eliminates allergens, cigarette smoke, dust, pollen, and bacteria while releasing a slight, fresh ozone concentration of 0.02 ppm. Main advantages include its maintenance-free, filterless construction that only requires periodic cleaning with an included brush, alongside zero operating noise. However, notable drawbacks include its lack of a physical HEPA filter for capturing microscopic particulates and a strict coverage limit restricted to smaller room sizes.
