Philips Air Purifier AC1711/90

Key features

Fast and effective purification: The AC1711/90 has a Clean Air Delivery Rate (CADR) of 300 m³/h and can purify rooms up to 78 m². Philips notes that the powerful airflow distributes ultra-clean air effectively throughout the room.
Advanced filtration:
- The 3-in-1 integrated filter combines a pre-filter, NanoProtect HEPA, and active carbon layers.
- This system is effective at removing 99.97% of particles as small as 0.003 microns, including viruses, bacteria, allergens, pollen, dust, and PM2.5.
- The NanoProtect HEPA technology uses an electrostatic charge to attract pollutants, enabling it to purify the air faster than a standard HEPA H13 filter.
Smart sensors: The professional-grade AeraSense sensor scans the air 1,000 times per second to detect harmful pollutants. It automatically adjusts the fan speed as needed and provides real-time feedback on air quality via a color ring and a numerical PM2.5 display.
Quiet operation: For nighttime use, the air purifier features a quiet sleep mode with a minimum noise level of 18 dB. You can also dim or turn off the UI lights to avoid disturbance.
Low energy consumption: The unit is energy-efficient, with a maximum power consumption of just 27 W, which is equivalent to a standard light bulb
