UM10011 specifications

The Philips UM10011 is a state-of-the-art air purifier designed to enhance indoor air quality and ensure a healthier living environment. This advanced device employs a range of innovative technologies and features that make it a standout choice for consumers looking to breathe clean air in their homes.

One of the primary features of the UM10011 is its Multi-stage Filtration System. This system includes a pre-filter, HEPA filter, and activated carbon filter that work together to capture a wide variety of airborne pollutants. The pre-filter effectively traps larger particles like dust and pet hair, while the HEPA filter captures up to 99.97% of particles as small as 0.3 microns, including allergens, pollen, and even some bacteria and viruses. The activated carbon filter plays a crucial role in removing odors and harmful gases from the air, ensuring a fresher atmosphere.

The UM10011 is equipped with advanced air quality sensing technology. It continuously monitors the air quality in real time and adjusts its performance accordingly. An intuitive display provides users with information on current air quality levels, allowing them to understand the impact of the purifier in real time. When pollution levels rise, the device automatically increases its fan speed to provide enhanced purification.

Noise levels are also a significant consideration for the UM10011. Its ultra-silent operation ensures that it can be used in quiet settings, such as bedrooms or offices, without causing distractions. The device features multiple fan speed settings, enabling users to customize the intensity of air purification based on their specific needs.

In addition to its performance features, the UM10011 boasts a sleek and modern design that fits seamlessly into various home aesthetics. It is compact and lightweight, allowing for easy portability from one room to another. Energy efficiency is another hallmark of the device, designed to operate with minimal power consumption while delivering optimal air purification capabilities.

Overall, the Philips UM10011 is a sophisticated air purifier that combines advanced filtration technology, real-time air quality monitoring, and user-friendly design. Whether it's to reduce allergens or eliminate odors, this device offers an effective solution for maintaining clean and healthy air in your home.
