Foam filter glue

[Tussy2]

I wouldn't glue it - you're actually going to make your life more difficult. Dirty foam filters can be heavy - you're making it heavier. Rinsing even a 1" thick foam filter can take a few minutes to get all the gunk out - a thicker filter will take much longer. All in all I think you're overthinking this one.

I service a neighbour's pond filter (Bioforce 12,000) and it's filters are 50 mm thick. Sure they get heavy, when clogged, but manageable.

couldn't agree more; I didn't even think how heavy this is going to be, though, I did wonder if any gluing would stand up to the machinations of continual washing, manipulating...And I'd surely just do as I first suggested; go to a foam store and get one piece cut. But, deaf ears and all...

So, basically all you are interested in is what type of adhesive to use? You could try a marine adhesive, or PL roofing goop. Be sure to let it dry well, and be gentle with the filters — I would expect tearing to happen due to the weight.

Well 2 inches (50mm) is one thing - I got the impression you wanted to glue many layers together.

Same here.

I don't think any glue will last very long, but that's just a guess.

Sewing them together with fishing line, as someone suggested, might be the way to go.

Is it possible to buy bigger pieces that will fit properly?

the weight of the waterlogged foam is going to tear along any stitching line, I would put money on it. And already suggested buying a one piece from a surplus foam store.
