DISCON.
The PHILIPS AC4558/31 Air Purifier, part of the advanced Series 4500i, is engineered to provide cleaner, healthier air for your home. Featuring a powerful Clean Air Delivery Rate (CADR) of 400 m³/h (PM2.5) and effectively covering rooms up to 48 m², this unit utilizes a multi-layer filtration system, including a Pre-filter, Activated Carbon filter, and HEPA filter, to efficiently reduce PM2.5, harmful gases, and allergens. Designed with a sleek aesthetic, the AC4558/31 combines robust performance with a modern design to complement any living space while delivering superior air purification.
Advanced Filtration System
The Philips AC4558/31 employs the VitaShield IPS (Intelligent Purification System) technology, a multi-layered filtration system designed to capture an array of airborne pollutants. This includes:
- Pre-filter: Captures larger particles like dust and pet dander.
- Activated Carbon Filter: Effectively removes harmful gases, odors, and VOCs (Volatile Organic Compounds) such as formaldehyde and benzene.
- HEPA Filter: Filters out ultrafine particles as small as 0.003 microns, including PM2.5, allergens, pollen, bacteria, and viruses, with up to 99.97% efficiency.
Smart Air Sensing with AeraSense
Equipped with Philips' advanced AeraSense technology, the AC4558/31 intelligently monitors indoor air quality in real-time. It provides accurate, real-time feedback on PM2.5 levels, allergen index, and gas levels via its digital display. The purifier automatically adjusts its fan speed to optimize purification based on current air conditions, ensuring continuous protection.
Multiple Operation Modes
Customize your air purification experience with a variety of modes:
- Auto Mode: Automatically adjusts fan speed based on air quality.
- Allergen Mode: Specially designed to detect and remove common airborne allergens more aggressively.
- Sleep Mode: Operates at a whisper-quiet noise level (as low as 20 dB) with dimmed lights for undisturbed rest.
- Turbo Mode: Delivers maximum CADR for rapid purification when needed.
Seamless Connectivity with Philips Clean Home+ App
