What you are getting
A 24-pack of carbon filters and sponge filters for stainless steel fountains. $17.99 — $1.50 a filter on a twelve-and-twelve split.
The only set here aimed at steel fountains
“Compatible with most stainless steel cat water fountain.” That is a material rather than a capacity, and it is the only listing on this shelf to frame compatibility that way.
It is also the vaguest. “Most” is not a model list, and the page carries no dimensions at all — no filter size, no sponge size. The maker asks you to “check whether it is compatible with your cat water fountains before purchasing”, which is sound advice that the page itself makes hard to follow.
The shortest change interval on the shelf
Every one to two weeks, where every other listing here says two to four. The reasoning given is the usual one — drinking frequency and number of pets — but the number is half the shelf’s norm, and at $1.50 a filter that doubles the running cost.
The soak instruction is the most careful here
“To prevent activated carbon dust (which will not harm your pet), soak the carbon filter in a separate bowl for 5 minutes and rinse for 30 seconds.”
A separate bowl, named. Carbon dust in a fountain bowl clouds the water and ends up in the pump; every other listing says soak and rinse without saying where.
What is not published
No dimensions, no capacity, no model list, and no carbon weight. The split between filters and sponges inside the 24 is not stated either.

The questions owners ask
Will it fit my fountain?
The page cannot tell you. It says "compatible with most stainless steel cat water fountain" and gives no dimensions, no capacity and no model list — then asks you to check compatibility before buying. The practical approach is to measure the filter you are replacing: the common generic on this shelf is 3.9 × 3.9 × 0.4 inch, published by three other brands here.
Why change every one to two weeks?
The listing does not justify it beyond drinking frequency and pet count. Every other set on this shelf says two to four weeks, and the shelf guidance is that carbon is spent after two to four weeks whatever the packaging claims. At $1.50 a filter, following this interval instead of the usual one roughly doubles what the fountain costs to run.
What is the separate bowl for?
Carbon dust. A new pad sheds fine black particles for the first rinse; soaking it in the fountain bowl puts that dust straight into the water and, worse, into the pump. This is the only listing on this shelf to specify a separate bowl and a thirty-second rinse, and the advice is right whichever filter you buy.
