Tetra® Whisper EX20 Carbon Filters
Frustrating that they don't make the economy packs for this model!
These filters are great, but it's very frustrating that they don't make economy packs for this model. Also, only having pre-made filters available is inconvenient when there's a situation where one needs to run a carbon-less filter.

Works well, but.....
Very expensive! At 31 days, the water starts to look dirty. For that price, it should work longer!
