How often do the filters and/or other parts in your large room purifier have to be replaced?
Filters are recommended to be changed when the unit alerts you.
The iAdapt unit will alert you when it is time to change the filter. The uniqueness of our technology and it's ability to purify the air outside of the unit should increase the length of time in between filter changes. UV lamps will need to changed when the light is no longer visible. Bi-Polar modules can be checked periodically with a voltage meter to insure proper ion production when necessary.
