As of January, 2022 the Flip Litter Box lid includes brackets for the Modkat Litter Box Filter Kit. To use follow these instructions:
- Remove the metal clip from the filter basket by gently wiggling it out of the holes. (If installed)
- Place a Modkat Bamboo Charcoal Filter into the filter basket.
- Use your thumb to hold the filter in place while sliding two corners of the basket into two of the corner brackets.
- Pinch and twist the basket slightly to fit the other two corners of the basket into the remaining two corner brackets. You should hear a click when they are fully engaged.
