What we like about Philips 800i Series AC0850/11

  • Highly effective at removing allergens, hay fever triggers, and dust particles
  • Great at neutralizing strong cooking odors and smoke smells
  • Ultra-quiet performance when running in sleep/night mode
  • Saves on electricity bills due to low energy consumption (only 20W)
  • Responsive real-time color ring indicator and accurate automated fan adjustments
  • App integration allows for convenient remote scheduling and smart monitoring

What we don't like about Philips 800i Series AC0850/11

  • Fan noise gets noticeably loud when running on full turbo mode
  • Initial Wi-Fi configuration and pairing with the Air+ app can be complicated
  • The physical built-in screen/display on the unit is remarkably small
  • Original Philips replacement filters can be expensive over time

Verdict

The Philips 800i Series AC0850/11 is a compact air purifier designed for rooms up to 49 m², featuring a Clean Air Delivery Rate (CADR) of 190 m³/h and a 3-layer filtration system consisting of a pre-filter, Active Carbon filter, and a NanoProtect HEPA filter that captures 99.5% of ultra-fine particles down to 0.003 microns. Key advantages include its ability to clear air in a 20 m² room in under 16 minutes, smart sensors that scan the air 1,000 times per second to automatically adjust speeds, an energy-efficient maximum power draw of 20 W, real-time air quality color-ring feedback, and an ultra-quiet sleep mode operating at 19 dB alongside Wi-Fi connectivity for the Philips Air+ app. However, its manual controls offer limited speed configurations (only Sleep, Speed 1, and Turbo), it lacks a built-in timer, and the composite filter must be completely replaced every 12 months rather than allowing individual layer changes.
