The replacement foam pads fit perfectly into my Rena Nexx filter. After installing them, I noticed a significant improvement in water clarity. The filter handles small debris well and requires no frequent cleaning. I’ve used them for three months now and they still perform effectively.

Easy to install and matches the original filter design. The 30 ppi rating helps catch fine particles that were previously passing through. I haven’t had to clean it as often as before, which is a nice change.

Great quality and fits exactly. I replaced the old foam and immediately saw better filtration. The pads stay in place and don’t degrade quickly. Works well with my tank’s flow and keeps the water clean.
