They must be replaced every 100–200 hours.
Don’t forget to replace the other filters in good time:
Pre-filter (10–30 hours)
Medium-efficiency filter (50–150 hours)
H13 HEPA filter (100–200 hours)
Activated carbon filter (300–600 hours)
Remove the filters:
Simply open the top cover of the filter and remove the cardboard from inside. Then remove the pre-filter and pull on the tabs on either side of the medium-efficiency filter, set it aside and repeat the same steps with the carbon filter. The box that remains is the H13 HEPA filter.
Replace the necessary filters.
