    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.

    Philips 2-in-1 air purifier & humidifier
    [This review was collected as part of a promotion.] Easy to use and set up on your phone where you can monitor your air quality within your house. Definitely can feel improvement of the air. I use it in my baby nursery and find my baby's sleep has improved. Definitely would recommend to parents whose children have allergies or if you have pets around your house. Very modern and useful product.

    Good looking product
    [This review was collected as part of a promotion.] Overall the product is a very good looking product. Its slick and fits in well into an environment. The set up is incredibly easy and I love that it functions off an app as well as being able to function via the buttons on the product. It is incredibly quiet and you really don't notice its on. My only hesitation to recommending this product to others is because we have used another air purifier in the past and this one doesn't seem as good in terms of refreshing the air. The humidifier function however is fantastic and has great coverage unlike other humidifiers I have used in the past, it seemed to really help my sons asthma during the night! Good looking air purifier

    The perfect addition to my family!
    [This review was collected as part of a promotion.] I am so incredibly happy with this product. The look and ease of setting it all up with the app is only the start of how perfect it is! I have a large living area, with a dog and two kids. The two in one purifier and humidifier keeps the air clean and safe for my whole family. I love how it is quiet and easy it is to clean and maintain. The fact that the app sends you reminders to clean the filter etc. is perfect for me, who is busy with two young kids! The app is incredibly easy to use and continues to update me on the current air quality. I could not recommend this product highly enough!

    Questions & answers

    What are the cleaning and sterilising requirements Flamingo · 2026-05-23
    Hello Thank you for thsi product question: Cleaning & Sterilising Requirements Weekly maintenance Empty and rinse the 3.2L water tank weekly. Clean the humidification filter/wick once a week to prevent mineral build-up and maintain hygienic operation. Wipe external surfaces with a soft, dry or slightly damp cloth. Every 1–2 months Clean the particle sensor gently with a dry cotton swab. Vacuum the surface of the pre-filter when the filter-clean alert appears. Filter care The pre-filter can be cleaned. HEPA and activated carbon filters must not be washed or sterilised with liquids — they are replacement filters. The purifier will notify you when filter replacement is required.
