When should I replace the HEPA filter in my AENO AP4 Air Purifier?

[JulietAnn]

To ensure your AENO AP4 Air Purifier continues to perform optimally, replace the HEPA filter every 2,200 operating hours. This typically means replacing it every 3 to 6 months. Proper maintenance of the HEPA filter is crucial for the air purifier's effectiveness. The control panel's Filter button will blink, and you'll hear a sound when it's time for a replacement. While the filter itself shouldn't be rinsed with water, regular cleaning with a soft cloth and a mild detergent is recommended. Be sure the filter is completely dry before placing it back into the AENO AP4 Air Purifier.
