1. Efficient Pollutant Filtration: The filter element of an air purifier is the core component. Different filter types target various pollutants. For example, HEPA filters effectively capture dust, pollen, smoke, and other tiny particles in the air, while carbon filters absorb unwanted gases and eliminate odors. Timely filter replacement ensures the air purifier continues to clean the air efficiently, maintaining a clean and healthy air environment. 2. Optimized Cleaning Efficiency: The replaced filter has lower air resistance, allowing air to flow through at a more stable speed and flow rate. This enables the air purifier to deliver performance as designed. 3. Reduce Operational Load: By replacing the filter element on time, you can maintain the machine's normal operating performance, reduce the workload on various components, and extend the air purifier's lifespan. 4. Prevent Malfunctions: Regular filter replacement helps sustain the machine's normal operation, lowers the risk of failure, and avoids the costs and inconveniences of repairs due to machine damage.
