Top Fin Silenstream PF-S Refill for PF10 Power Filters 5.5in x 3.1- (12 Count) 1 Year Supply

This is a great filter to use with both topfin and tetra filter machines. I tried the Tetra Whisper Bio Bags Cartridges and it did not work as well as these filters do. The water was always cloudy, even when I replaced with a new cartridge. Plus there is no mess to clean up when changing out the charcoal. I recommend using these cartridges. Easy to clean and very easy to replace each time.

Excellent quality and price for these filters. I have three fish tanks and with the pandemic and everyone getting fish tanks set up, couldnt find any filters and when I did the price was crazy. I was happy to find these. Got a good backup supply and when I run out will continue to buy these.

The filters are amazing quality but the box came in looking like it had been kicked around and sat on!! I was so shocked that none of the filters were damaged at all with how much the box was banged around and dented. Just be careful ordering these filters and check them very thoroughly because your box is guaranteed to arrive all banged up.

This pack is great value for the money and exactly what I needed.

Ive used other filters for my koi tank and they could never work perfectly like Top Fin Silenstream.

Product works as expected. Your filters should say PF-S on the black tab at the top of the filters for these to fit correctly. The review options are so bizarre. What is sheerness or thickness in reference to regarding the quality of aquarium filters?

Box was crushed. Looks like someone stepped on it.

tried to order cn-l filters ,i returned . thank you anyway dan

I love this product, the only reason I bought it off Amazon was free shipping. This is ridiculous though. I’m not buying this again from here.

Were going through our filters like crazy since were breeding guppies for a year long school project. The filter is unique since it lets us know when it needs to be changed with a little red indicator when it is dirty. it lasts a while when we dont overload the tank with too much food at a time. It was tiresome to go into the store monthly for these when we could just get this 12 pack and significantly minimize our trips.
