    Overview

    The Philips PureProtect Water 3400 Series Smart 2-in-1 Air Purifier and Humidifier transforms your indoor environment into a haven of fresh, clean, and perfectly balanced air. Designed for households prioritising health, comfort, and smart living, this elegant device effortlessly combines high-performance air purification with natural, hygienic humidification. It’s particularly suited for families with babies or individuals sensitive to allergens, pollutants, or dry air, delivering noticeable improvements in both air quality and overall wellbeing.

    Covering large spaces up to 78 m², its robust airflow purifies the air in a 20 m² room in under 10 minutes, ensuring you breathe easy even in expansive living areas. The triple-layer HEPA NanoProtect and Active Carbon filtration system traps an impressive 99.97% of ultrafine particles — even those smaller than most viruses — while the NanoCloud humidification technology releases ultra-fine mist with 99.9% fewer bacteria compared to standard ultrasonic humidifiers.

    Smart features elevate the user experience: the built-in AeraSense sensors continuously monitor air quality, automatically adjusting settings for optimal performance, while the Philips Air+ app provides remote control, real-time monitoring, and integration with Google Assistant or Alexa for voice commands. Sleep mode keeps operation ultra-quiet at just 16.5 dB, and its 3.2 L water tank allows up to 15 hours of continuous humidification without refilling.

    Not only does it tackle common allergens, dust, and dry air, it also effectively reduces airborne viruses like H1N1 and SARS-CoV-2, offering peace of mind for health-conscious households. Energy-efficient and elegantly designed, the PureProtect 3400 Series is a sophisticated addition to any modern home, blending powerful air care with intuitive smart features that adapt seamlessly to your daily life.
