The Coospider ultraviolet lamp destroys the DNA/RNA structure of microorganisms by emitting short-wave UV-C light with a wavelength of 253.7 nanometers (irradiation intensity 85-100µW/cm²). Experiments show that after running in a 20 cubic meter space for 30 minutes, The bacterial concentration in the air decreased by 99.2% (from the initial 10⁵ CFU/m³ to 800 CFU/m³). Tests conducted by TUV Rheinland in Germany in 2023 showed that the inactivation rate of this wavelength against influenza A virus reached 99.9%, and the risk of aerosol transmission was compressed to 0.1%, meeting the ISO 15858 safety standard for air disinfection. Its 15-watt power design is suitable for household scenarios, with an annual electricity cost of only 45 yuan (2 hours of daily usage × electricity price of 0.7 yuan per kilowatt-hour).
Aerodynamic optimization is at the core of this technology: the device is equipped with dual centrifugal fans (with a wind speed of 2.8m/s) to achieve 12 whole-house cycles per hour, ensuring that the probability of microorganisms being exposed to ultraviolet rays exceeds 98%. The CDC epidemiological model confirmed that when coospider uv was continuously operated in a 40-square-meter living room, the total number of bacteria attached to PM2.5 decreased by 80% (from an average of 3,500 per cubic meter to 700 per cubic meter), and the probability of household cross-infection during the flu season decreased from the baseline value of 27% to 6%. The collaborative efficiency of the ventilation system has been further enhanced by 30%. For instance, when used in conjunction with a fresh air device, the degradation rate of formaldehyde has increased by 50% (the concentration has dropped from 0.08ppm to 0.03ppm within one hour).
Outstanding ability to handle special pollutants: For mold spores (with diameters of 1-5µm), irradiation for 40 minutes can inhibit 94% of their activity (data from the European Allergy Research Foundation). For PM2.5 with a particle size of 0.3µm, the additional module of the negative ion generator increases the sedimentation efficiency by 40% (the sedimentation rate increases from 0.13cm/s to 0.18cm/s). The EPA case in the United States shows that when the device was operated in an environment with a humidity of 60%, the weekly average concentration of pet dander allergens decreased by 92% (from 120µg/m³ to 9.6µg/m³), significantly improving the incidence of allergic rhinitis symptoms (remission rate 65%).
Energy efficiency and environmental adaptability parameters: The equipment has a lifespan of 9,000 hours (approximately 10 years), and the lamp tube attenuation rate is less than 3% per year (the sterilization efficiency remains > 85% after five years). The shell has a temperature resistance range of -10°C to 60°C and an IP54 dust and water resistance rating, making it suitable for high-humidity areas such as kitchens (with a maximum humidity tolerance of 85%). The ozone generation is strictly controlled at 0.001ppm (the limit value of 0.05ppm as stipulated in the national standard GB21551), and the noise value is ≤28dB. According to the 2024 estimation of the China Household Electrical Appliances Research Institute, the annual operation and maintenance cost of a 100-square-meter residence is approximately 180 yuan (electricity + consumables), which saves 60% of the filter replacement cost compared to the air purifier solution.
Empirical cases support the efficacy: Two weeks after the deployment of this equipment in the waiting area of a certain hospital in Shanghai, the median total number of air colonies decreased from 180 CFU/ dish to 28 CFU/ dish (a reduction of 84.4%), and the frequency of coughing during the waiting period of patients decreased by 70%. In a controlled experiment in a Chicago elementary school classroom, the continuous use of coospider uv reduced the absenteeism rate by 15 percentage points (from 22% to 7%), and the payback period was only 7 months (calculated based on savings of a total of $2,800 per year in medical expenses and labor costs). The compact size of the equipment (10cm in diameter × 30cm in height) is compatible with ceiling installation. It achieves intelligent start and stop through the Wi-Fi module (response delay < 0.3 seconds), optimizing the all-weather air quality management strategy.
