What are the dimensions for these replacements?

Answer by ChewyApr 30, 2018
The dimensions for these Cartridges are 4.6 inches (length) by 6.4 inches (width).

Does it come with the carbon prepackaged or is it just the empty cartridge

Answer by ChewyApr 13, 2018
This product comes unassembled with empty cartridges. I've listed the following instructions below: 1. Detach clip from Aerobic Frame and slide the filter bag over the frame. 2. Add one packet of Ultra-activated carbon. 3. Press the Aerobic Frame flaps down over the top of the filter bag and press the clip down over the flaps. 4. Rinse under cool tap water to remove carbon dust. 5. Insert the Bio-Bag into filter slots.

I've been buying these filter cartridges for many years and I like them. What I didn't like was that the box came all squashed because they put it in with the cat litter boxes and 3 of the carbon bags broke.
