I purchased a spare to keep on hand

Thx

It's great to have a spare so you can swap them out when you clean your unit and then clean the filter. That being said it's a royal pain to get it lined up when reinstalling it.. several cuss words and 2 people later finally got it attached.. there has to be a better way to swap dirty for clean one

Filter

I'm loving the Popur! It is the best automatic cat litter cleaner. Saves me so much time with four indoor cats.
