What we like about LEICKE Pureo2

  • Equipped with a comprehensive 4-in-1 HEPA-13 filtration system and built-in UV-C light that effectively captures allergens, fine dust, and germ particles
  • Sensitive air quality sensor reacts instantly to airborne impurities like cigarette smoke and kitchen fumes by automatically adjusting fan speeds
  • Offers a highly efficient and rapid air purification performance, quickly lowering particle levels in medium to large rooms up to 80m²
  • Quiet sleep mode operating at roughly 22-24 dB ensures undisturbed use overnight in bedrooms
  • Intuitive digital touch display clearly shows useful real-time feedback including room temperature and color-coded air quality metrics
  • Responsive, reliable customer service from the manufacturer for prompt filter replacements or assistance

What we don't like about LEICKE Pureo2

  • The device can become noticeably louder and run at maximum noise capacity when operating on its highest manual fan setting
  • Requires exclusive, proprietary replacement filters from the manufacturer as third-party alternatives are incompatible and risk damaging the unit
  • At a weight of 5.7 kg, the machine is somewhat heavy and lacks a built-in wheel design for seamless transport between rooms

Verdict

The LEICKE PureO2 is a 40W air purifier designed for medium-sized rooms up to 80 m², featuring a 4-in-1 filtration system—including a pre-filter, HEPA-13 filter, activated carbon filter, and cold catalyst—alongside a built-in UV-C disinfection lamp and negative ion generator. It operates with a Clean Air Delivery Rate (CADR) of 180 m³/h to capture 99.97% of fine dust, PM2.5, allergens, and ultra-fine particles down to 0.3 micrometers, while its integrated intelligent sensor monitors air quality to automatically adjust across three fan speeds via an LCD touch display or an infrared remote control. Key pros include its multi-stage allergen removal, integrated germ-killing UV-C light, an auto-adjusting smart mode, and a near-silent 22–24 dB sleep mode; however, cons include a higher noise profile on its highest setting and a strict compatibility restriction requiring proprietary LEICKE replacement filters to prevent device damage.
