The four-layer HEPA NanoProtect system, combined with a double Active Carbon layer, captures 99.97% of ultrafine particles, allergens, gases, and pollutants as small as 0.003 microns — smaller than most viruses. Integrated PM2.5, gas, allergen, temperature, and humidity sensors ensure the purifier constantly adapts to real-time conditions, providing optimum performance without user intervention.
SilentWings technology sets the PureProtect Pro 4200 apart, making it 35% quieter than previous models. Operating as quietly as 15 dB, it remains unobtrusive even at maximum speed, quieter than everyday conversation. Despite its powerful output, it’s energy-efficient, drawing just 54 W at full power, keeping running costs low.
Smart connectivity rounds out the experience, with Wi-Fi and app control through the Philips Air+ app and voice command compatibility with Google Assistant and Alexa, offering a seamless, hands-free experience. Crafted with over 30% recycled plastic, it’s a sophisticated, eco-conscious choice for households seeking healthier living spaces without compromise.
