Philips AC4221/61 Real Time AQI Display | Ideal for Living room | App Control with Wifi Smart Air Purifier, Dark Metallic

The Philips AC4221/61 Smart Air Purifier is a premium-class air purification solution designed to transform the air quality of your living room and larger indoor spaces. Engineered with advanced filtration technology and smart connectivity, it not only cleans the air quickly and effectively but also keeps you informed about the air you and your loved ones breathe every moment.

Ideal for rooms up to 72 m² (≈700 sq ft), this purifier delivers a high CADR (Clean Air Delivery Rate) of 600 m³/h, allowing it to completely purify the air in a standard room (18 ft × 12 ft × 8 ft ceiling) in roughly 5 minutes. Whether your space is open-plan, a busy living area, or a shared family room, the AC4221/61 ensures fast and efficient coverage that keeps indoor air fresh and healthy.

At the heart of its performance is a 4-layer HEPA filtration system comprising a pre-filter, HEPA NanoProtect filter, and dual activated carbon layers. This powerful combination captures 99.97 % of microscopic particles as small as 0.003 microns, including pollen, dust, pet dander, smog, smoke, gases, and even many harmful microorganisms. The multi-stage purification ensures that both particulate pollutants and gaseous odors are effectively reduced, making the air safer and more breathable for everyone at home.

Despite its strong airflow and performance, the AC4221/61 is designed for quiet operation. Thanks to Philips’ SilentWings technology, it runs up to 50 % quieter than conventional purifiers and can operate as low as 15 dB — quieter than a whisper. This makes it perfect for nighttime use, day-to-day living, or while working and relaxing, with minimal distraction.

With built-in Wi-Fi connectivity, you can connect the air purifier to the intuitive Air+ App on your smartphone. The app lets you view real-time air quality readings, adjust fan speeds and modes, set schedules, and even control the unit remotely — a helpful feature for monitoring and ensuring clean air for family members like kids and senior citizens, even when you’re away from home.

Aesthetically, the AC4221/61 blends form with function. Its sleek dark metallic finish complements modern interiors, while the soft ambient lighting — including the AQI ring and integrated night light feature — adds both style and practical feedback by visually indicating current air quality levels at a glance.

Durable, efficient, and smart, this air purifier is an excellent pick for homes where air quality matters most, offering robust performance, cutting-edge filtration, and convenience wrapped in a stylish design.
