the filters should be found here:

not sure what size you need for your popup, i know we needed a short one for our old highwall - i think the reorder number is on the filter housing.
but you may want to consider removing the filter and use an external one. that way, if the housing breaks, the flood will be outside the camper.
we did that for both the old highwall and our current hybrid.
