How do I use the Odor Filter with the Flip lid?

As of January, 2022 the Flip Litter Box lid includes brackets for the Odor Filter Kit. To use follow these instructions: 

1. Remove the metal clip from the filter basket by gently wiggling it out of the holes. (If installed)
2. Place a Modkat Bamboo Charcoal Filter into the filter basket.
3. Use your thumb to hold the filter in place while sliding two corners of the basket into two of the corner brackets.
4. 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.
