How often should I change the Carbon Filter?

For optimal odour absorption, we recommend changing the carbon filter every three months, but replacement frequency is up to you and your cats usage patterns. If you use scented litter, we recommend changing the filter more often as it will also absorb the litter scent.

Note:The carbon filter is not necessary for the unit to function.
