Foam Filter Layers - Small

Used it in my box filter great fit and they work really well

A third of the price of similar product in retail store. Does the job, very pleased

These fitted the need at the time, though in less than a season they are already worn out and breaking down so I will have to buy more in the spring. Unlike my original set which lasted years before I needed to replace them. Shame, but what can you do, Cheap Chinese C..p really.

After a while they degrade, but then again they're not a lot of money

Cleans well and doesn't disintegrate after a few rinses

They do the job

works well in pond filter

Arrived quickly and easy to use.
