In terms of microbial inactivation efficiency, the Coospider ultraviolet lamp destroys the DNA/RNA structure of pathogens through UV-C radiation with a wavelength of 253.7 nanometers. Laboratory tests show that it operates in a 30-cubic-meter sealed space (with a relative humidity of 60%) for 30 minutes. The killing rate of Escherichia coli and Staphylococcus aureus reaches 99.1% (the initial concentration is reduced from 10⁵ CFU/cm² to 900 CFU/cm²). The 2023 SGS independent certification report confirmed that when the irradiation intensity of this equipment is 90µW/cm², it meets the inactivation requirements of ISO 15858 standard for airborne viruses. For example, the survival rate of the H1N1 virus after 10 minutes of contact is ≤0.3%.
For common household pollution scenarios, the efficiency of coospider uv in disinfecting object surfaces varies by material: the sterilization rate for stainless steel countertops is 98.5% (with a dose of 150,000 µW·s/cm²), while for textiles, it drops to 85% (due to the ultraviolet penetration depth being only 0.2mm). A case study from the New York University School of Medicine indicates that running a 25-square-meter kitchen three times a day (for 15 minutes each time) can reduce the weekly Salmonella density on chopping boards by 95% (stabilizing from a peak of 1200 CFU/cm² to 60 CFU/cm²). In terms of power consumption performance, the annual electricity cost for the 15-watt model is approximately 40 yuan (calculated based on one hour of daily use and an electricity price of 0.7 yuan per kilowatt-hour), saving 180 yuan in the annual budget compared to the chemical disinfectant solution.
In terms of equipment safety performance, Coospider is equipped with a human body sensing automatic power-off system (response time ≤0.1 seconds), ensuring that the radiation exposure is below the WHO safety threshold of 5mJ/cm². The lifespan of its quartz lamp tube reaches 9,000 hours (it can be used for 24 years based on an average of 1 hour per day), and the aging attenuation rate is controlled at 3% per year (that is, the sterilization efficiency remains above 85% after five years). In the 2022 EU CE certification crash test, the product achieved a 100% structural integrity rate under a 1.5-meter drop impact, and the shell was resistant to high temperatures of 120°C.
Economic benefit analysis of applicable scenarios: In a 60-square-meter residence, when combined with an air circulation system, the PM2.5 sedimentation efficiency is increased by 30%, and the concentration of microbial aerosols is reduced by 80% (from 2,500 per liter to 500 per liter). Compared with hospital-grade ultraviolet equipment (with an average price of over 2,000 yuan), the Coospider home-use model has a price range of 300 to 800 yuan, and the investment payback period is approximately 8 months (calculated based on an average annual reduction of 600 yuan in medical expenses for respiratory infections). A simulation experiment conducted by the Chinese Center for Disease Control and Prevention in 2024 shows that regular use of this device can reduce the probability of flu outbreaks in households from the benchmark value of 22% to 7%.
Technical limitation description: The inactivation of mold spores by UV-C requires extended irradiation for 40 minutes (efficiency 93% vs. The bacteria account for 99%, and there are disinfection blind spots in the shaded areas (with a coverage rate of approximately 90%). It is recommended to use it in combination with a surface cleaner. For instance, in a damp bathroom environment (with a humidity of over 80%), ultraviolet light alone needs to be doubled to 30 watts to inhibit the growth rate of black mold (the antibacterial rate increases from 68% to 91%). The test data from German TUV shows that the operating noise of this equipment is ≤35dB, and the ozone generation is 0.001ppm (far lower than the upper limit of 0.05ppm stipulated by the national standard), achieving eco-friendly protection.
Empirical data support: In a three-month field test at a kindergarten in Guangzhou, the absence rate due to illness in classrooms equipped with coospider uv devices decreased by 18 percentage points (from 25% to 7%), and the median total number of colonies on object surfaces dropped from 85 CFU/cm² to 12 CFU/cm². The device size has been optimized to 8cm in diameter and 25cm in length, which can be integrated into the air duct of a household fresh air system (with a wind speed tolerance limit of 8m/s), and is compatible with the modern smart home’s automated disinfection strategy.
