Description

The Clean Air Optima CA-503B Compact Smart filter kills bacteria, viruses, and fungi. This is because the air purifier has a UV-C lamp, which kills harmful bacteria, viruses, and fungi. With the HEPA 13 filter, it removes dust, allergens, and other particles from the air. The ionizer lowers floating particles to the floor. The air purifier has a sensor that measures the air quality and it automatically adjusts its operation if it senses pollution. You can connect the air purifier to the smartphone app to control it remotely and to gain insight in the air quality. It cleans the air in rooms of up to 28m2. Thanks to the extra silent night mode, you can also use it in your bedroom.
