How Often to Replace Coway Filter? Here is a simple answer to this question.

On average, Coway true HEPA air filters need to be changed every 12 months. Although keep in mind that “how often to change filter” depends on three factors:

  • How often do you run your Coway air purifier and at what speed;
  • What model do you have;
  • What is overall air quality indoor. The more pollutants present in the air the faster air filter has to be replaced.

In any case an indicator will light up to let you know when you have to change it. I replace my Coway AP-1512HH air filter once a year, and it runs 12 to 16 hours per day.

Carbon filter has to be replaced every 6 months on average.
