What is this product?

Gas-powered leaf blowers using 2-stroke engines that emit unburned fuel, oil, CO, NOx, and PM2.5 at rates dramatically exceeding modern vehicles. CARB: operating a commercial leaf blower for 1 hour emits smog-forming pollutants equivalent to driving a 2017 Toyota Camry 1,100 miles. California banned sales of new gas-powered small off-road engines (including leaf blowers) effective January 2024. Noise: gas leaf blowers produce 75-90+ dB at operator position, exceeding OSHA limits for 8-hour exposure.
