Thanks** A: Must be a secret - I sure don't understand why the seller doesn't clearly list the size.Whisper Bio-Bag Filters are slightly tapered in the drawing. Width dimensions are at the top.Large: 4.6 wide x 6.4 tallMedium/"Junior": 3.0 wide x 5.2 tallSmall: 2.1 wide x 3.8 tallFound dimensions on the Tetra website but not sure the link address will work here. Here is the PDF file link:http://cdn.spectrumbrands.com/~/media/UPG/Tetra/Aquarium/Equipment/Replacement%20Filter%20Cartridges/WhisperCartridges.ashxIf this doesn't work go to their website at: www.tetra-fish.com and search for "Tetra Whisper Unassembled Bio-Bag Filter Cartridges" **Q: Does it fit topfin power filter 10?** A: I bought these about a month ago for my top fin 10 filter. The cartridge in my top fin 10 is angled inward at the bottom whereas this filter cartridge is more of a rectangular shape. Due to the shape it does not fit the top fin 10 slot. However I kept my old cartridge frame and I'm using this product, everything works great. **Q: What is the difference between the 26164 and ATS26164? Both seem to be 12 large Whisper filter cartridges.** A: Hi, I use the Medium size whisper filter cartridges...the difference between the 26164 & ATS26164 could be the fact that one is a pre-assembled cartridge and the other is not. I buy the 12 pack of unassembled filters which are quite a bit cheaper and are the identical product. It comes with the white filters, one plastic insert, and small charcoal bags that take a few minutes to assemble. Hope this helps. **Q: medium size it's for 10 galons?** A: Hi Oscar, the medium size fits the Whisper PF10 and the Whisper 20 Power Filters. ## Frequently Bought Together - Tetra Whisper Bio-Bag Filter Cartridges for Aquariums, Medium Filter for Freshwater and Marine Fish, Removes Odors and Discoloration, Easy to Assemble, 12 Large Green Filters - Tetra Water Cleaner Gravel Siphon for Aquariums, Easily Clean Freshwater Aquariums --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/2116011-whisper-bio-bag-medium-filter-cartridges-for-aquariums-12-count](https://www.desertcart.sg/products/2116011-whisper-bio-bag-medium-filter-cartridges-for-aquariums-12-count) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-07-09*
