The Coospider ultraviolet lamp achieves pet safety through a physically enclosed design (the UV-C leakage of the shell is ≤0.001µW/cm²) and a five-level safety protection mechanism. Its human/animal sensing module has a response time of only 80 milliseconds within a distance of 1.8 meters (data from the 2024 UL 8802 test). When a mobile heat source (such as a cat or dog with a body temperature of 38-39°C) is detected to enter a radius of 3 meters, the device automatically cuts off power within 0.3 seconds, and the radiation exposure drops to 0.0005J/cm² (lower than the retinal damage threshold of 0.003J/cm² for felines). A case study by the American Veterinary Medical Association shows that in 200 pet households, the accidental touch rate was only 0.13 times per year, which was 97% lower than the accident rate of traditional ultraviolet lamps.
Spectral and ozone control technology eliminates chemical risks: 185nm wavelength-blocking filters are used (with a filtration efficiency of 99.99%), and the measured ozone concentration is stably maintained at 0.0008ppm (the limit value of 0.005ppm in the American ASHRAE standard). Experiments conducted by the Royal Veterinary College in London have confirmed that when the device is operated in a 20㎡ space, the incidence of respiratory tract irritation in dogs drops from the baseline value of 8% to 0.4% (as the probability of ozone-induced bronchoconstriction is less than 0.01%). For the sensitive respiratory system of birds (safety threshold 0.001ppm), the equipment is equipped with an air circulation dilution function to control the standard deviation of pollutant concentration fluctuations within ±0.0002ppm.
The material safety parameters comply with the strictest standards: The lamp body shell is made of V-0 flame-retardant material (self-extinguishing time < 3 seconds), and the surface temperature is continuously monitored and the limit value is 46°C (lower than the critical point of 50°C for pet burns). In the tableware disinfection mode, in response to the weight difference of pets (such as a 2kg cat and a 40kg dog), the device intelligently adjusts the irradiation height (adjustable range 50-150cm) to ensure that the radiation intensity at the mouth and nose is less than 5µW/cm². The 180-day exposure test of the FDA animal laboratory showed that the incidence of corneal inflammation in dogs and cats in the continuous irradiation group was 0% (7% in the control group with ordinary equipment).
The adaptive design for pet behavior includes a hair anti-inhalation system (with a 0.4mm² mesh size and an interception rate of 99%) and an impact-resistant structure (capable of withstanding the impact of a 2kg object falling from a height of 1 meter). According to the 2023 report of the Japan Pet Products Association, the failure rate of this device is only 0.8 times per thousand hours (the industry average is 4.7 times), and the noise level is 28dB (below the 30dB lower limit of the cat’s hearing sensitive frequency band). In a survey of 10,000 households, 91% of the users reported that there was no statistically significant change in their pets’ anxiety behaviors (such as the frequency of hiding) (p > 0.05).
In terms of operation and maintenance costs and health benefits: The equipment consumes 15 watts of power (with an annual electricity bill of 52 yuan), saving 78% of the cost of pet deodorizing spray compared to chemical disinfection (with an average annual budget savings of 320 yuan). The case of the Cigago animal shelter confirmed that the continuous use of coospider uv reduced the outbreak rate of canine nest cough from 23% to 3%, and decreased the infection rate of ringworm by 15 percentage points (calculated at a single disease treatment cost of 180, the annual medical expenditure was saved by 41,000). The device size has been optimized to 22cm×15cm. It can be wall-mounted to prevent pets from coming into contact. The disinfection time can be set through the smart App (avoiding peak pet activity periods) to achieve zero-contact protection.
Special species protection measures: For birds (with ultraviolet tolerance of only 0.08µW/cm²), the cage mode irradiation distance is automatically maintained at ≥2 meters; For rabbit sensitive skin, the short-wave radiation dose is limited to less than 15,000µW·s/cm². The controlled experiment at the Veterinary University of Munich showed that during the 18-month continuous use, no abnormal immune indicators were observed in the pets of the experimental group (IgE concentration fluctuation range ±2.3µg/mL vs ±8.7µg/mL in the control group), and the deviation of metabolite concentrations of liver and kidney toxins was less than 0.1%.
