The Philips PureProtect Water 3400 Series Smart 2-in-1 Air Purifier and Humidifier (AC3421/13) transforms your indoor environment by combining powerful air purification with advanced humidification. Designed to purify spaces up to 78 m², it circulates clean, hydrated air throughout your home, dramatically improving comfort and air quality. Its three-layer HEPA filtration system captures an impressive 99.97% of particles as tiny as 0.003 microns — smaller than most viruses — ensuring your air stays fresh, clean, and free from pollutants, allergens, and harmful microorganisms.

With automatic humidification delivering up to 650 ml/h, the unit quickly alleviates dry-air discomfort like dry skin, scratchy throat, or irritated sinuses. Its NanoCloud technology disperses an ultra-fine mist that carries 99.9% fewer bacteria compared to standard ultrasonic humidifiers, using safe tap water without spreading white dust or wet spots. This makes it a superb choice for families, allergy sufferers, and anyone seeking a healthier living space.

Integrated smart features, including app control, timers, and automatic adjustments, make it easy to maintain ideal air quality and humidity levels without constant attention. And with a sleek black design, compact footprint, and quiet operation at just 51 dB, it fits seamlessly into modern homes.
