Someone put a sticker on top that read OBE. Inside the box, the ceramic filter itself was not sealed.Initially, the water passing through this filter was great. I even called up family raving about how this ceramic filter made the water taste like it just came up from an underground aquifer. The first problem I noticed showed up on my TDS meter. The water before the filter, coming from the reverse osmosis unit, was 4 TDS, after this ceramic filter, it was 16 TDS. If I ran the water for ten minutes, the TDS reading would drop to around 6 or 7. Every morning was the same, starting at 16 TDS. After doing this for seven days, the TDS would start at 7. This was not a big issue. On the tenth day, the water had more of a smooth creamy texture to it. I thought this was normal. Shortly after drinking a cup of this water I felt physically sick to my stomach. After draining the holding tank, I opened the filter housing and examined the ceramic filter. The inner chamber, which contained the filtered water, had, to my surprise, many particles floating in it. Why those particles didn't get flushed out, I don't know. Maybe they were too heavy. I dumped the water and rinsed the ceramic filter and the filter housing. The next morning, after drinking another cup of this ceramic filtered water, I felt sick again. I pulled the tubing out, bypassing the ceramic filter, and filled up a glass of water. This water (before the ceramic) tasted fresh and pure, and had a TDS reading of 4. I immediately started the return process with Amazon. ### ⭐⭐⭐⭐⭐ Cool *by T***1 on Reviewed in the United States on January 14, 2020* Very good ### ⭐⭐⭐⭐⭐ Five Stars *by R***O on Reviewed in the United States on May 31, 2018* it's excellente filter great buyng and good price --- ## 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/6555708-doulton-w9220402-slimline-sterasyl-obe-ceramic-filter](https://www.desertcart.tn/products/6555708-doulton-w9220402-slimline-sterasyl-obe-ceramic-filter) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-03*
