To maintain peak performance, the COSMO P500 Pro Air Purifier's filters should typically be replaced every 12 months. This recommendation is based on an average usage of 8 hours daily at a low fan speed. The air purifier features a convenient filter replacement indicator to help you. When it's time for new filters, this indicator will illuminate, often blinking red. Be sure to replace your filters when prompted to ensure the COSMO P500 Pro continues to purify your air efficiently. Note that these filters are designed for single use and are not washable or reusable.
