CADR stands for Clean Air Delivery Rate, and it's crucial to pay attention to the unit when comparing: is it meters (should be cubic meters) or feet (should be cubic feet), per minute or per hour? The volume of air pushed out doesn't necessarily equate to performance; the amount of truly clean air it can produce is what matters. Higher CADR values typically mean higher prices and suitability for larger room sizes. Just as with air conditioners, if the cooling capacity is insufficient, the compressor will continuously run, not only consuming more electricity but also failing to lower the temperature effectively. Therefore, it is recommended to choose a model with a higher CADR value within your budget. Here's an introduction to negative ions: 1. Improve Air Quality: The World Health Organization believes that when the concentration of negative ions in the air reaches over 1000 per cubic centimeter, it can enhance human immunity and resistance. 2. Breakdown Toxic Substances: Capable of degrading formaldehyde, benzene, VOCs, and PM2.5, among other harmful substances. 3. Antiseptic Effect: Achieves a杀菌 rate of over 99%. 4. Odor Removal: Significantly eliminates odors in rooms, particularly in kitchens and bathrooms, with more noticeable results. 5. Due to the benefits of negative ions to life and health, they are known as the "vital element of air" and the "longevity element." 6. Negative ions have a positive effect on the human respiratory system, nervous system, circulatory system, skin system, metabolic system, immune system, and ten other major systems.
