First, thanks for posting this design! I made one. Well, am making one. I'm having trouble getting the fan to pull air through the filters. I was wondering if you had any pointers? I've even switched to a 120mm 120v high speed fan. Or, it is possible I'm overthinking it lol Any thoughts/advice/suggestions appreciated! Thanks!

Thanks for the help. I honestly think I was just expecting to "feel" the air flow more and was over thinking it. Set up worked great!

The one we've been using just pulls a small amount of air through, which is only noticeable in that our litter box isn't as dusty or malodorous as without the system. I used a low speed 12V fan on ours for the sake of near silence for us and the cats, and there is hardly any air movement felt when you put a hand over the intake inside the box. The filters are pretty dense when paired together, but even a relatively weak fan should be able to pull enough air through to make a difference. I hope this helps!

Where's the stl of the adorable cat?

She won't sit still long enough for a very good photogrammetry session ;)
