What has to be observed when carrying out maintenance on a PurAir toilet?
The PurAir toilet is a low-maintenance product. Only the filter has to be changed once a year, and the batteries too, if the PurAir toilet is battery-operated. The service life of the batteries depends on the battery type-and the intensity of use. The batteries last approx. 5-6 months in a 4-person household with average use.
