Steps On How To Replace The Air Filter

  3. Before replacing the pre-filter, check the HEPA filter to see if it is full of dust. If the HEPA filter has already turned gray or black, it is time to replace it.
  4. To change the HEPA filter, grab the tabs on the old HEPA filters and attach the new one. Follow the airflow labels when attaching the replacements.
  5. Attach the new air pre-filter. Once you turn on the air purifier later, it will hold the pre-filter in place. We advise changing the air pre-filter every two to three months.
  6. Winix air purifier has a timer that will tell you when to change air filters.
  7. Plug in the air purifier and turn on the unit. Find the filter reset button and press it for five seconds. Some Winix model types, such as 6300-2, 5500-2, 5300-2, C555, C535, and Winix Zero, need a safety pin or bobby pin to reset the filter notification.
