Philips 1000 Series Air Purifier for Medium Rooms AC1711/90

Purifies the air in less than 10 minutes. Purifies rooms up to 78 m² with a clean air delivery rate (CADR) of 300 m³/h. A 3‑layer filtration system with NanoProtect HEPA, active carbon and a pre‑filter removes 99.97% of particles as small as 0.003 μm, capturing viruses, allergens, pollen, dust, pet dander, PM2.5 and gases. VitaShield technology removes up to 99.9% of viruses and aerosols from the air. The professional‑grade AeraSense sensor scans the air 1,000 times a second, displays allergen and PM2.5 levels in real time and automatically adjusts the purification speed. Low‑energy design runs at just 27 W and operates quietly in sleep mode with dimmable lights. Smart filter replacement indicator calculates filter lifetime based on pollution level and usage. Easy maintenance thanks to a compact cylindrical body with an integrated 3‑in‑1 filter. Auto mode plus four manual speed levels (Sleep, Speed 1, Speed 2 and Turbo). Certified by ECARF for continuous 24/7 operation.
