Hello Dan,

cartridges anymore,...

I have a similar problem. I solved it by cutting the right piece of filter
material out of a filter from an other manufacturer.


I'm not sure this will work in my case. Each canister is kind of a figure 8
shape and it seems difficult to get the filter to attach to that kind of
frame without gaps forming. Might be worth a try though. thanks,
