Each individual box includes 3 replacement filter cartridges. The 1 count comes with 1 box and the 3 count comes with 3 boxes.

Correct one...

These are the ones I have been using for years.. unfortunately by the time I received them my pump stopped working and now can't find another one.

Fantastic Find

So I never knew there was a special filter just for my aquatic turtle. Finding this on Chewy was a bonus to my new found knowledge on aquatic turtle care. This is on my subscription, allowing me to keep our turtle's water clean and clear. Pair this with the API Turtle Sludge Destroyer Aquarium Cleaner (which is a magic potion in itself), and you will never have your turtle disappear into the sludge fog ever again!!

Good filter for at least one turtle tank

This filter provides decent filtration for a aquarium of 20 gallons to 30 gallons for at least one turtle with proper sludge control added. Chewy offers them for a more valuable price as well.

Reptofilter Cartridges 3 Count

I love these cartridges and all of their actual filters that these fit into. They have various sizes and are ready to use. I do feel they should be sold in packs of 4 instead of 3 though, because all of their filters either take 1 or 2 cartridges at a time. So, when I buy these cartridges for my 2 filters, I have to buy 2 packs of 3 at a time, in order l to have enough for them both. But overall, they do indeed work well.
