The filters I use in my indoor terrariums and my large tropical aquarium are made by a company called Fluval. Not only are these the most expensive but for good reason because they are the most effective and most durable with standard features that most top end lines of other brands don't even offer. Now for the stupid part, all of the models in the 02, 03, 04, 05 & 06 class take either one, two or four elements such as bio cells, charcoal bags and pre-filter media but the replacements are only sold in sets of three... Maybe I am just too demanding but that is very wasteful and suspiciously "money making" and seeing that the model I use costs 189 bucks each and I have 7 of them well you can see why I am unhappy about the practice.
