Easy to cut to fit our litter box. Not much else to say about them! ### ⭐⭐⭐⭐⭐ Fits the litter box *by L***N on June 23, 2025* Fit my nature’s miracle litter box. ### ⭐⭐⭐⭐ Decent Replacement Filter for Litter Box Lid *by S***E on September 15, 2022* Old filter was in bad shape so it was time to replace. I took a chance on this set. It's made differently and much more porous than the old ones. Seems to be doing the job about the same and installed easily enough. So, they're worth the price. ## Frequently Bought Together - Fresh Headquarters 6Pack Oval 8×3in Activated Carbon Litter Box Filters – Compatible with Nature’s Miracle Oval Covered Box – Eliminates up to 99 % Odors - Nature’s Miracle Hooded Flip Top Litter Box for Cats, With Built-In Odor Control Charcoal Filter - Petmate Scoop N' Hide Cat Litter Scoop with Discreet Litter Scoop Holder, Brushed Nickel --- ## 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/231838996-fresh-headquarters-6-pack-activated-carbon-cat-litter-box-filter](https://www.desertcart.sg/products/231838996-fresh-headquarters-6-pack-activated-carbon-cat-litter-box-filter) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-06-04*
