### ⭐⭐⭐⭐⭐ Perfect
*by B***A on January 6, 2026*

Perfect for my U1 water filter. Feels and looks exactly like the the name brand

### ⭐⭐⭐⭐ Perfect pore size for prefilter
*by D***G on August 18, 2025*

You get ten @ filter foam at size 7.72 x 2.36 x 0.51 inches each. Small so you need to check out what you need. I like the porosity poly sponge like consistency , so i got them and superglued them together (see pic) to make them fit my overflow box size of 7.7" x 4.7" . A great prefilter foam to get out the bigger particles for efficient filtering with the dense foam media and carbon/chem media on the bottom . Great value and easy to rinse out for reuse.
