When using an air purifier, regular maintenance and replacement of the air purifier filters are essential tasks. However, for those new to this task, there may be some uncertainties about when to replace them and how to do so. In the following article, Puritrak will share useful information to help you easily accomplish this task.
1. When to Replace Air Purifier Filters
Before starting the process of replacing air purifier filters, it’s important to know when to do so. The timing of filter replacement depends on the type of filter, the level of air pollution, and the frequency of air purifier usage.
For pre-filters: The lifespan of pre-filters is directly related to the lifespan of the purifier itself, so there’s no need to replace them separately. However, it’s important to ensure regular cleaning of the pre-filter membrane 1-2 times per month.
Activated carbon filters: The replacement interval depends on the usage level of the air purifier and the living environment. Typically, the frequency of replacing activated carbon filters is every 6-12 months. However, there may be special cases where earlier or later replacement is necessary.
HEPA filters: HEPA filters are the most important layer in an air purifier. The replacement interval for HEPA filters is usually between 12 to 24 months, depending on the level of air pollution and the purifier’s capacity. Regular replacement of HEPA filters ensures the efficient operation of the air purifier and provides healthy, clean air for your living space.
