How do I know that I need to replace my Guardian Air Purifier filter?

It is important for your Air Purifier to run properly, that your filter be clean to promote proper airflow. You will notice your filter needs to be replaced when the filter turns from white to gray/black/brown, or if your filter is black originally, the filter will turn greyish-white with dust.

The maximum lifespan for a filter is approximately 6-months, depending on the usage and the environment it is used in. 

Replacement filters can be purchased at our online store, which can be found here

Here are some examples of dirty filters:

• The pre-filter can be vacuumed monthly and will look like this.

   

• The HEPA filter will turn from white to gray.
