Rougher side towards back, or rougher side towards front? Thanks!** A: Coarser filter goes to the back so that it can remove the bigger particles before filtering on the finer side. My filter unit has two cartridges so I change one alternately every time I do a water change, every 3 weeks. **Q: Can someone please measure the filter with a ruler. Several people have asked and no one has answered with actual measurements.** A: Thank you for asking Penny! They are 5-3/4" high x 4.5" wide. **Q: have a filter with red insert carbon filter has to be attached to fits inside of 35 gallon filter can't remember which filter type it was help** A: I would recommend you call our team at 1-800-526-0650 if you think it was one of ours. The red insert could be a bio grid which comes with one of our lines. Also, look at the top of the filter. We mold the model name and size in all of our lids. **Q: im needing to find the "cage/holder for theses filters. Any one have a Parrt #?** A: no ..don't have a part...write to the company... --- ## 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.ph/products/11596603-tetra-whisper-ex-carbon-medium-round-filter-cartridges-4-count](https://www.desertcart.ph/products/11596603-tetra-whisper-ex-carbon-medium-round-filter-cartridges-4-count) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-07-19*
