great

Fits great better than the original

Work great!!

Works as they should

Excellent replacement for OEM filters. Quite a bit cheaper and seem to be doing just as good of a job and last roughly the same time. Fit perfectly into the original housing.

The filters fit and work good. However if you want to reuse them like you do with the original filters when you soak them in 1/2 bleach and water solution over night. The rubber ends become gummy and hard to clean off. I would recommenced to only use them once and then replace. Other than that they work fine and for the price its worth it.

👍

I soak my filters in Clorox between cleanings. These filters don't hold up to that, the plastic disintegrate in the bleach. I got 2 uses out of them before they were trashed. Going back to the OEM filters that actually hold up.

As described but found expensive

Fairly good filter. Cheaper than the name brand ones but it definitely isn't made as well. The blue plastic on the top/bottom gets worn if left in the bleach solution too long, and then get weird and sticky. I've found that if I just leave it in the solution for a couple of hours, it doesn't ruin the plastic and can be used again and again before you have to throw it out. I use it for my red eared slider turtle's tank (40 gallons). Seems to keep it pretty clear for over a week before needing to be switched out.
