Nice and thick. Really cuts down on the smell. Affordable as well. ### ⭐⭐⭐⭐⭐ Good replacement *by J***N on March 11, 2023* They work well , definitely reduce for replacement of your old carbon filter. I haven’t had any issues with Oder leaking through , it works very well. ### ⭐⭐⭐⭐⭐ Smells are at 60% reduced *by D***A on May 17, 2023* I have the original WIFI litter robot and bought these to get a little more longevity from the unit. It’s not emptying quit as well as it used to and the tray just seems to hold less in volume and smell . These helped a lot to filter the smell that was becoming burdensome. The original filter isn’t quite as thick as these replacements. --- ## 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.no/products/439919716-biodefensor-8-pack-true-carbon-filters-compatible-with-litter-robot](https://www.desertcart.no/products/439919716-biodefensor-8-pack-true-carbon-filters-compatible-with-litter-robot) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-16*
