The Philips PureProtect Water 3400 Series AC3421/13 is a smart air purifier and humidifier combination that quietly and effectively cleans indoor air. The device also removes smaller particles such as allergens and viruses, providing clean and safe indoor air for your home. NanoCloud technology automatically humidifies the air, reducing the harmful effects of dry air. Thanks to its quiet operation, the device is also suitable for use at night and consumes very little energy. Smart app features and automatic air quality monitoring make usage effortless and energy-efficient.
Comprehensive purification for rooms up to 78 m²
This device effectively cleans spaces up to 78 m², with an airflow of 300 m³/h covering the entire room. A smaller 20 m² room can be purified in less than 10 minutes.
3-layer HEPA filtration captures up to 99.97% of even the smallest particles
The pre-filter, HEPA NanoProtect, and activated carbon filter capture particles as small as 0.003 microns—smaller than known viruses.
Automatic humidification up to 650 ml/h
The device humidifies the air up to 650 ml/h and automatically adjusts the humidity. NanoCloud technology produces pure water vapor that is so fine bacteria do not adhere to it. Thanks to this technology, humidification is up to 99.9% cleaner compared to conventional ultrasonic humidifier modules without bacteria-preventing technology.
Effectively reduces viruses
Removes 99.9% of airborne viruses and bacteria, including H1N1 influenza and COVID-19.
Energy-efficient and extremely quiet in night mode
In night mode, the device’s noise level is only 16.5 dB, quieter than a whisper. The digital display dims so the light does not disturb sleep. The device consumes only 43 W at maximum power, less than a typical incandescent bulb.
Smart air quality detection and adjustment
AeraSense technology monitors air quality 1000 times per second and automatically selects the best fan speed, displaying air quality (PM2.5) and humidity in real time.
Control via Philips Air+ app
The Air+ app allows you to monitor air quality and control the device remotely. Auto+ mode adjusts the device’s operation to suit your preferences and routines.
Against odors and gas pollution
The activated carbon filter removes over 90% of gas pollutants and odors, such as traffic emissions and chemicals from furniture. No ions, chemicals, or ozone.
3.2-liter water tank and long-lasting filter
The 3.2-liter water tank ensures up to 15 hours of continuous humidification without refilling. Original filters guarantee optimal performance for up to one year, and the device notifies you when the filter needs to be replaced.
