Cat Fountain Filters for Giotohun S11 Series (12 Pack) with Carbon and Foam Sponges
Product description
What this is
This listing covers a 12-pack set of replacement filters for Giotohun cat water fountains, compatible with S11, S11-pro, S11-plus and S11-pluspro models in 2.2L and 3.2L stainless steel dispensers. Each pack includes 12 filters and 12 sponges for the pump.

How it works
The filters use a three-layer filtration system: a pre-filter sponge to catch large particles, a high-density fleece to trap fine debris, activated carbon to improve taste and reduce odours, and an ion exchange resin to soften water and reduce heavy metals. This combination aims to deliver cleaner, fresher-tasting water to encourage cats to drink more regularly.

What to like about it


On paper, these filters address common concerns: hair and debris removal, better-tasting water, and a straightforward replacement routine. If you have multiple pets or notice your fountain water going stale quickly, the 3-layer approach and the included sponges give you a comprehensive refresh option. The instruction to soak the new filters before use helps minimize activated carbon dust entering the water, which is a practical touch for keeping the drinking stream clean.

What may not convince you
The description relies on standard filtration claims without independent testing data. Real-world performance can depend on your tap water quality, the size of your cat’s drinking habits, and how often you perform routine fountain cleaning. If you prioritise absolute filtration performance or quiet operation, you might want to compare with alternatives that offer different filter materials or fewer replacement items per cycle.

Who it’s for
These filters suit cat owners using Giotohun S11 family fountains who want a practical, all-in-one replacement solution and don’t mind carrying out regular maintenance (every 2–4 weeks, more often with several pets).



Who it’s not for
If you’re not using a Giotohun S11-series fountain, or you expect minimal maintenance with very long-lasting filters, this kit may not be the best fit. It also assumes you’re comfortable replacing both filters and sponges and rinsing components before reassembly.

When it makes sense to buy
Consider it when you want a ready-to-use replacement pack that covers both filtration stages (carbon and foam) and includes appropriate sponges for the pump. It’s sensible if you’re aiming to maintain water freshness and encourage higher water intake for your cat, especially in households with multiple pets.
What to review before purchasing


- Confirm your fountain model and capacity (2.2L or 3.2L) aligns with the compatible Giotohun S11 series.
- Note the replacement frequency (2–4 weeks) and assess whether that cadence fits your routine.
- Be aware of the need to soak and rinse filters prior to first use to minimise carbon dust in the water.
- Consider your water quality, if you have very hard water or heavy metal concerns, the ion-exchange resin feature is relevant.
Practical usage example
A typical morning routine: you swap the old filters for the new 12-pack set, rinse each sponge and filter under running water, soak the new filters for a few minutes, and then reassemble the fountain. The cat returns to a water stream that smells fresher and tastes cleaner, which may help with regular drinking during the day.
FAQ
- How often should I replace the filters? Generally every 2–4 weeks, depending on pet numbers and consumption.
- Do I need to replace the sponges as well? Yes, the pack includes sponges for the pump and it’s recommended to replace them with the filters.
