I found it a little complicated to figure out how it works so definitely YouTube before you set up once you have it set up. It works great. ### ⭐⭐⭐⭐ Support resolved issue after filter replacement where a chemical gel was inside the pure water tank. *by E***T on December 26, 2025* UPDATE: Moved this from 1 start to 4 after receiving pretty good support/response from customer service. Support ended up replacing the unit without any shipping charges. It appears the replacement filter I put into the original unit caused it to break/"gum up" with some type of substance that leaked out of the filter. The good news here is if you do have a problem, their support will do what they can to make it right. Used the unit for 5mo before the filter was at 50% and the TDS meter was showing the decrease in water purity. I drink at least 1.5L/day so 5mo out of a filter at that amount isn't bad. After replacing the water filter for the first time, and the system running through a filter flush, the system initially filtered the usual liter or so of water. I drank that and the system's feed tank was empty. I refilled the water feed tank and then the system started failing to filter. Shortly after when going through checking the system, I noticed a clear gel substance in the pure water tank. I now resultantly have ingested some type of chemical clear gel'ish residue that was in the pure water tank (see below): Everything seemed ok with the new filter. Within 24 hours the system stopped filtering and displayed an E04. I ran through the steps to check and reseat the filter, feed tank, and pure water tank. When I was reseating the pure water tank, I noticed a clear gel on the inside of it which had not been there before. Looks like the new filter ruptured or something and now I've ingested some type of chemical from that filter. I now can't trust this system to not be contaminated with some type of chemical. This was supposed to be a dependable system. It's cost sure is commensurate with quality. It's ended up now causing a health concern and leaving me out $250 cost of the unit plus $76 cost on the new filter. Tried to reach customer support via their chat bot. Waiting on them to get back to me. ## Frequently Bought Together - [Alkaline Mineral] Waterdrop CoreRO Reverse Osmosis System, NSF/ANSI 58 & 372 Certified, 7-Stage Countertop Reverse Osmosis Water Filter, No Installation Required, Reduce PFAS, BPA Free, WD-C1SL - Maxblue MB-PWT Pure Water Tank, BPA Free, 34 OZ, Portable Pure Water Tank for WD-C1S and WD-C1H Countertop Reverse Osmosis System --- ## 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.co.za/products/676541314-waterdrop-c1sl-mineral-reverse-osmosis-system-nsf-ansi-58-372](https://www.desertcart.co.za/products/676541314-waterdrop-c1sl-mineral-reverse-osmosis-system-nsf-ansi-58-372) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-04-23*
