Now I wish I had, since the DI is almost completely amber now after only ~30 gallons of water and it is now showing 1ppm on my in-line TDS meter instead of the expected 0. The TDS from the membrane, before the DI chamber, is only 2 and is consistently only 2, so this was just a bad batch of resin. Very disappointed. --- ## 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.tn/products/73752665-avanti-color-changing-deionization-di-cartridge-w-resintech-mbd-30](https://www.desertcart.tn/products/73752665-avanti-color-changing-deionization-di-cartridge-w-resintech-mbd-30) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-21*
