When should I replace my filter?

Manufacturers indicate a filter life span because it is necessary information during the selection process. However, 2 pieces of information should be taken into account:

• For a combined filter with HEPA + activated carbon filtration: as soon as the filter is removed from its plastic packaging, the activated carbon will start to capture VOCs and other odors even if the air purifier is not turned on.
• The use of the air purifier plays a major role in the filter's life span. An air purifier that operates at maximum speed in a very polluted environment will have a shorter lifespan than one used at reduced speed in a cleaner environment.

In all cases, a light (often red) will tell you when to change the filter.
