Try to find one where you can easily remove the caps, so you can refill it with active carbon pellets when it needs to be renewed.
Some brands have the caps bolted on, there you would have to remove the bolts first (probably by drilling through them). In other brands they use regular screws to keep the caps in place. These are easily removed, then you can open the filter and exchange the coal pellets.
Refilling saves money and reduces waste.
