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

[DiNevaeh]

For peak performance, replace the HEPA filter in your AENO AP4 Air Purifier after approximately 2,200 hours of use, which typically equates to every 3 to 6 months. To maintain optimal air purification, it's crucial to adhere to this replacement schedule. Your AENO AP4 will also alert you when it's time for a filter change – the Filter button on the control panel will blink, accompanied by an audible signal. While the HEPA filter shouldn't be rinsed with water or used beyond its lifespan, you can extend its life by regularly cleaning it with a soft cloth and a gentle, neutral detergent. Always ensure the filter is completely dry before putting it back into the AENO AP4 Air Purifier.
