Drinking Fountain Neptune Filter (3 pieces)

The listing doesn’t clearly show the product’s measurements. With so many products in the same post, it’s hard to tell. The filters I bought are very square-shaped. I went by the picture and thought they would fit well. I’ll still use them by squeezing them in and making them fit, at least until I buy the original brand replacement (which is more expensive). They seem to be good quality. The mistake was mine for not checking the filter size.
