For optimal performance, replace the filter in your Levoit LV-H135 Console True HEPA Air Purifier every 6-8 months. This is based on typical usage, but your specific needs may vary. Factors like your home's air quality and how frequently you use the air purifier can influence how often the filter needs changing. Watch for signs such as increased noise, reduced airflow, unusual smells, or a visibly dirty filter; these indicate it's time for a replacement. To maintain the efficiency of your Levoit LV-H135, always use genuine Levoit replacement filters. After installing a new filter, remember to reset the Check Filter Indicator to ensure accurate filter replacement reminders.
