With just one push of a button, the air purifier filters the invisible viruses, allergens or pollutants in your home to keep it clean and safe. Fast purification for 78 m² Powerful airflow circulation effectively covers spaces up to 78 m and distributes ultra clean air in every corner of the room. 1) 99.97% particle removal A 3-layer filtration with Nano - Protect HEPA, active carbon and pre-filter makes sure you are protected from bacteria, pollen, dust, PM2.5, pet dander and gases. The Nano - Protect HEPA technology not only captures pollutants, but It uses an electrostatic charge to attract them, enabling it to purify the air faster than a HEPA H13 filter that is medically used.( 5) Up to 99.9% virus removal The Vita - Shield technology captures aerosols and particles smaller than the smallest known Coronavirus (6). Virtually nothing escapes from Vita - Shield - It deactivates viruses and traps them inside. Tested independently by Airmid health-group to remove up to 99.9% of viruses and aerosols from the air (2). Also, tested for corona virus (7). Scan and visualize The professional grade Aera - Sense sensor accurately scans the air 1000x a second to detect harmful pollutants and intelligently chooses the right speed for every environment. It displays the air quality in real time, showing level of allergens and PM2.5 in numerical form, as well as with an intuitive colour ring. Quality you can trust Philips purifiers go through 170 mandatory and strict inspection tests before they are released from our factory and are certified by the European Centre for Allergy Research Foundation. They are subjected to rigorous life and durability tests for continuous operation (24/7). Ultra-quiet & no disturbance In sleep mode, the purifier operates in near silence for clean air while you sleep. Both air quality index and the light on the UI can be dimmed or turned off to avoid any light disturbance. Low energy consumption Thanks to its energy efficient design, the air purifier runs at max. 27 W power. This is equivalent to an incandescent light bulb. It is compliant with a highly efficient grade of strict global standard. Smart filter indicator The air purifier accurately calculates filter lifetime based on pollution level and operation time. It notifies you when the filter needs replacement, for easy maintenance. Easy maintenance The air purifier is designed for easier cleaning, using the compact and simple cylindrical plastic body. It uses a 3 in 1 integrated filter so no need to change each filter separately. Key Features Purifies the air in less than 10 min Suitable for spaces of up to 78 m² Removes up to 99.9% of viruses and aerosols from the air HEPA & Active carbon filter Connected with Clean - Home+ app (1)From the air that passed through the filter, it is a theoretical time for one-time cleaning calculated by dividing the room size of 48m³ by CADR 300m³/h (assuming the room is 20m² in floor area and 2,4 m in height). (2)Microbial Reduction Rate Test conducted at Airmid Health group Ltd. tested in a 28.5m³ test chamber contaminated with airborne influenza A(H1N1), in Turbo mode after 10-20 mins. An air purifier by itself does not protect against Covid-19, but can be part of the plan to protect yourself and your family (US Environmental Protection Agency) (3)From the air that passes through the filter. Tested with Na - Cl aerosol by i - UTA according to DIN71460-1 (4)From the air that passes through the filter, tested with birch pollen dust on filter media according to SOP 350.003 of the Austrian OFI institute (5)Nano - Protect HEPA filter material provides lower air flow resistance than the material from a HEPA H13 filter, enabling a Philips air purifier with Nano (6)From the air that passes through the filter, tested with Na - Cl aerosol by i - UTA according to DIN71460-1.
