What if I see white dust after installing the F300 Electronic Air Cleaner?

Last updated

The presence of “white dust” is actually an indicator that your Electronic Air Cleaner is working properly. The Electronic Air Cleaner can only filter the particles that are passing through your system’s duct work. The staining particulate is generally lighter, and more able to be drawn through the return registers in your home, leaving the heavier, non-staining particulate behind. This heavier, non-staining particulate settles out of the air and is left behind on your furniture: because it is more visible, it may appear as though there is actually more dust in your home than there was prior to installing the air cleaner. To ensure that more particulate is able to reach the Electronic Air Cleaner to be filtered, you should make sure that the return registers are clean and not blocked by furniture.
