How big is your pool?
These are fairly small filters.
This is basically the same as a Quad DE filter, only you have just one filter element instead of four.
I have a Quad DE filter on my pool, and like it. It holds a ton of dirt, and I can backwash if I like, or just tear it down.
Filter elements are very sturdy. I have had mine for almost 5 years, and they look as good as new.
