3. When should I replace my filters?

Be it a dust filter, deodorizing filter or humidifier filter. Most air purifiers have time-based reiminders to remind customers when to replace their filters. At HEPAPAPA , besides the time-based reminders, we recommend that you check your filters every month for these telltale signs as to when to replace your filters.

HEPA Filter
1. When the filter is dirty or has turned black.
2. When the air from the blower feels like it is stuck.
3. When there is a musky odor.

Carbon Filter
1. When it is no long absorbing odors

Humidifier Filter
1. When there is algae growth or when the filter has disintegrated
