A filter refill is useful when you want to maintain aquarium filtration with a cartridge made for your existing equipment. These Silenstream cartridges are intended for aquariums using the compatible PF10 Power Filter. Their active carbon addresses undesirable odors, pigments, and chlorine, while the specified cartridge size gives you another practical point to compare when choosing a refill. The pack contains six cartridges for ongoing replacement needs.

Which filter do these cartridges fit?

These cartridges are made for Top Fin PF10 Power Filters. Choose them by matching the filter model, rather than relying on the cartridge name alone. The cartridge measures 5.5 x 3.1 in (14 x 7.9 cm), which provides a size reference alongside the model match. This makes the refill choice straightforward for an aquarium owner who already uses a PF10.

• Compatible filter model: PF10 Power Filter.
• Cartridge size: 5.5 x 3.1 in (14 x 7.9 cm).

What does the active carbon help with?

The active carbon helps absorb undesirable odors, pigments, and chlorine. This is the cartridge’s stated carbon function and makes it a relevant refill for aquarium owners seeking those filtration benefits. The cartridge is intended to work as part of a compatible power filter; the carbon feature does not change the PF10 model fit.

• Carbon media targets undesirable odors.
• It also helps absorb pigments and chlorine.

How many cartridges are included?

The pack contains six Top Fin Silenstream PF-S Small Filter Cartridges. Having multiple refills together can help you plan for future cartridge changes without selecting a single replacement at a time. Each piece is the small PF-S cartridge format for the compatible filter, so the count refers to six cartridges rather than six filters.

• Pack quantity: six filter cartridges.
• Product type: replacement cartridges, not a power filter.

These refills suit aquarium owners using a Top Fin PF10 Power Filter who want a cartridge with active carbon to help absorb undesirable odors, pigments, and chlorine. Match the filter model and cartridge dimensions when selecting this refill. For a PF10 setup, the six-count pack combines a model-specific fit with the stated carbon function.
