The figure shows the circuit diagram of the negative ion air freshener. In addition to filtering the air, the device can achieve deuterated air, and can also generate negative oxygen ions in addition to the purpose of removing smoke, dust, and removing odor. Negative oxygen ions enter the body through the respiratory tract, which can improve and strengthen heart and lung function. Negative oxygen ions can exist for 5-6 minutes in clean air, and the time to survive in very dirty air is very short, about one minute. Therefore, use it as close as possible to the breathing zone of the person to achieve better results.
