What we like about PuroAir 100i

  • Highly effective at reducing dust, dander, allergens, and airborne particles in small rooms
  • Excellent at neutralizing unwanted odours and smoke
  • Compact, 'lunchbox-sized' design that is easy to place in tight spaces like desks, baby rooms, or offices
  • Convenient smartphone integration that allows for instant remote control and scheduling
  • Quiet operation on lower fan speeds, making it ideal for bedrooms

What we don't like about PuroAir 100i

  • Not suitable for large living rooms, basements, or open-plan areas due to its small footprint
  • Lacks the higher clean air delivery rate (CADR) found in larger models like the PuroAir 240 for heavy-duty pollution
  • Requires regular filter replacements to maintain optimal performance

Verdict

The PuroAir 100i is a compact, 2.1 kg corded-electric smart air purifier designed to clean spaces up to 550 sq ft within an hour using a 3-layer HEPA filtration system—consisting of a pre-filter, a HEPA layer, and a CarbonTech activated carbon filter—that captures up to 99.9% of fine particles as small as 0.1 microns, including dust, pollen, pet dander, smoke, and odors. Notable characteristics and pros include its built-in PM2.5 air quality sensor with a three-level color indicator, four adjustable fan speeds including a quiet sleep mode, a child safety lock, and seamless Wi-Fi/Bluetooth app connectivity for remote smartphone control. However, some minor cons include the recurring long-term cost of replacement filters that must be changed every 6 to 12 months, and occasional user complaints regarding occasional iOS app connectivity issues and crashes during initial setup.
