QT048 specifications

The Guardian Technologies QT048 is a highly sophisticated air purifier designed to enhance indoor air quality while delivering efficient and user-friendly performance. This state-of-the-art device is engineered with a focus on eliminating airborne pollutants, making it an ideal choice for homes and office spaces.

One of the standout features of the QT048 is its advanced filtration system, which employs a 3-in-1 True HEPA filter. This filter is capable of capturing up to 99.97% of airborne particles that are as small as 0.3 microns, including dust, pet dander, pollen, and smoke. In addition to the True HEPA filter, the QT048 also includes a charcoal filter that helps to neutralize odors, ensuring that the air remains fresh and pleasant to breathe.

The QT048 utilizes UV-C light technology, which works in tandem with the filtration system to effectively kill bacteria, viruses, and mold spores. This added layer of protection makes it particularly beneficial for households with allergy sufferers or individuals who are more susceptible to respiratory issues. The incorporation of UV-C light not only contributes to cleaner air but also promotes a healthier living environment.

User convenience is a key aspect of the Guardian Technologies QT048. It features a sleek, compact design that easily fits into various room sizes without taking up too much space. Additionally, the air purifier operates quietly, making it suitable for use in bedrooms or during quiet hours without causing disturbances.

The device is also equipped with a built-in filter replacement indicator, which alerts users when it’s time to change the filters, ensuring optimal performance at all times. The QT048 offers multiple fan speeds, allowing users to customize their air purification experience based on their specific needs and preferences.

Moreover, the Guardian Technologies QT048 is energy efficient, which means it can operate continuously without significantly increasing electricity bills. This efficiency, combined with its effective purification capabilities, makes it not just a smart choice for health-conscious consumers but also an environmentally friendly option.

In summary, the Guardian Technologies QT048 air purifier represents an excellent investment in indoor air quality. With its advanced HEPA filtration, UV-C technology, user-friendly design, and energy-efficient operation, it stands out as a top contender in the air purification market, promoting cleaner air and a healthier living space for all.
