In today's world, with increasing air pollution problems, indoor air quality is crucial for people's health. The LUFT Duo air purifier, with its innovative technology, brings fresh air to your life, making it more enjoyable and healthier. ## Core Technology and Features First and foremost, the core technology of the LUFT Duo is a combination of ion dust collection and photocata- lysis, effectively removing bacteria, viruses, allergens, formaldehyde, and other pollutants from the air. It utilizes two photocatalytic materials: TiO2 for odor removal and ZnO + nano-silver particles to enhance the sterilization effect. These two photocatalysts generate redox reactions under light irradiation, breaking down harmful substances into harmless ones, achieving the purpose of purifying the air. It's worth noting that the LUFT Duo air purifier has passed UL's zero ozone emission test, ensuring that it does not produce harmful ozone to human health or the environment during use. Moreover, the product eliminates the need for filter replacement. Simply remove and clean the stainless steel antibacterial filter regularly for easy and eco-friendly maintenance. ## Compact Size for Localized Purification The compact size of the LUFT Duo air purifier makes it suitable for placement on desks, in bedrooms, or in cars, providing localized purified air. You don't have to worry about purified air not easily reaching your work or sleep area, allowing you to enjoy fresh air at any time. ## Simple User Interface Although the LUFT Duo air purifier does not feature smart networking and app control capabilities, its simple user interface allows for easy operation without worrying about network security issues. Focus on enjoying fresh air and making your life more relaxed and enjoyable. ## Customer Feedback and Indiegogo Success According to customer feedback on the Indiegogo platform, the LUFT Duo has shown excellent performance in improving indoor air quality and alleviating allergy symptoms.
