Oregon Scientific WS907 Brochure & Specs

Millions of people suffer from allergies, asthma, chronic respiratory conditions and chemical sensitivities. Pollutants enter from a variety of sources, including pets, plants, house dust, mites, smoke, paints, carpets, cooking and chemicals used in cleaning, making the air indoors unhealthy to breathe. They all threaten our family’s health. Applies advanced NCCO to super-efficiently break down and remove viruses, harmful odors, airborne bacteria, dust and mold spores that cause allergies and stress in human bodies. You will be able to monitor indoor air quality at any time by either looking at the digital air quality display on top or simply glance at the LED color display at the bottom. The Air Sanitizing System filter will last up to three years and is easy to replace. Its sleek design matches perfectly with any modern home or office.

Nano-confined Catalytic Oxidation (NCCO) Technology is excellent at air deodorization and sterilization. This technology is patented internationally. We strive to produce a wide range of air treatment products that could improve the air quality of not only common domestic and commercial environments but also the environments with the most undesirable air quality, like smoking lounges, food processing workshops and water treatment facilities. Nano-confined Catalytic Oxidation (NCCO) Technology was developed by members of the Entrepreneurship Center of the Hong Kong University of Science and Technology. NCCO’s technology is considered as the safest air purifying solution currently available with excellent efficiency. It can remove pollutants such as allergens, viruses, bacteria and TVOCs without releasing any oxidants into the air.

Pollutants and viruses will be locked inside the nano pores and break down oxidized particles into non-harmful substances, such as water and carbon dioxide. How NCCO works NCCO Technology has widely utilized in different locations and industries like the Hong Kong International Airport, hospitals, government organizations and banks. NCCO technology enhances the safety and trustworthiess of household items like the Oregon Scientific NCCO Air Sanitizing System.
