This is a compact device that doesn't have the huge footprint of most RO devices. We actually bought this primarily to filter the sodium out of our water that comes from our municipality. We do have a carbon block filter on our sink line that filters out the other bad stuff, but this filters out the high levels of sodium and any PFAS/PFOS remaining in our tap water. The results are amazing. PAY ATTENTION to the instructions when you first set it up, and make an entire morning or afternoon of it, ESPECIALLY if you have relatively high TDS. During the initial setup, you will have to empty and refill it at times, even if the feeder tank is not down to the full line. That is just part of the initial process. Once it indicates that it is ready, you won't have to replace the filter for a very long time. I set mine up in January and it is still running strong. This is fantastic value for the price and the water tastes better than any other filtered water I've ever had. Additional tips: measure your counter space before purchasing, and leave room to place a pitcher in front of it in case you want a lot of water at one time. Pick the feeder tank up from the handle AND the base in order to extend the life of the handle. When the water refill light goes on, always fill it before using it in order to extend the longevity of the overall product. Wait until the system stops humming before taking the feeder tank out to refill it. Hope you enjoy it as much as we do. ### ⭐⭐⭐⭐⭐ amazing *by on Reviewed in the United States August 4, 2025* Likes:- compact size- quiet operation- helpful setup interface- easy to use- water tastes greatI had a different RO system but apparently they quit selling filters for that model. I decided to go with a better known brand this time. The plastic feels a tad cheap but overall everthing is built well and works fine. I really liked how the machine walks you through the setup process to do it correctly. It also helps to read the well-written user manual. I plan to stay with this machine/brand indefinitely, as long as everything works well. ### ⭐⭐⭐⭐⭐ 1 Year Review + Customer Service Review *by on Reviewed in the United States January 31, 2025* This is a review after 6 months of daily usage. I did a lot of research before making a decision on which RO system to purchase, as I am very serious about my health. This product is superior to all other countertop RO systems on the market, as it allows you to clean and maintain all the individual reservoirs, including the reservoir where the RO water is stored after filtration, which is something that is very important and no other competitors products in this price range allow you the ability to do. Unfortunately, the handle on the feed water tank broke at one of it's hinges, making the system unusable. I contacted customer support via email, as this product comes with a one year warranty from the date of purchase. Robbie Li from customer support responded to my inquiry at lightning speed. I emailed late at night at around 1am and he responded by 3am. He kept me updated regularly throughout the entire process and got the part shipped to me within 3 days of it shipping via expedited shipping. I am very impressed by their excellent customer service and highly recommend both this product and this company.1 FULL YEAR UPDATE:This an updated full year review of this product. After about 8 to 9 months into usage, the system started experiencing issues with overfilling. Karina in customer service was very helpful in walking me through a descaling process to try to solve the issue, but unfortunately, to no success. After attempting to fix it and failing, she was quick to send me out a brand new system, at no extra cost to me whatsoever. The product itself is still fantastic and in my opinion, still one of the best you can get on the market that is within this price range, but the customer service is even better than the product itself. I do hope that they can improve upon their design so that future models do not have this overfilling issue later on in it's lifespan, but it is still a great product! Thanks again Karina for all of the help!ANOTHER UPDATE:After about a month of daily usage with my replacement machine, it unfortunately started showing issues with it spitting water into two streams instead of one out of the dispenser while dispensing water. I contacted Karina in customer service once again about this issue, and she was very kind in sending me yet another brand new system. This system seems to be working fine, and there are no issues with it so far. I think I was just unlucky in getting a defective machine for the replacement the first time around. But I would like to thank Karina once again in helping to quickly resolve my issue and helping me to stay a satisfied customer once again! ## Frequently Bought Together - Waterdrop CoreRO Countertop Reverse Osmosis System, NSF/ANSI 58 & 372 Certified, 6-Stage, Portable Reverse Osmosis Water Filter, Reduce PFAS, No Installation Required, BPA Free, WD-C1S - Maxblue MB-PWT Pure Water Tank, BPA Free, 34 OZ, Portable Pure Water Tank for WD-C1S and WD-C1H Countertop Reverse Osmosis System - Waterdrop WD-C1RF Filter with RO membrane, Replacement for WD-C1S and WD-C1H Countertop CoreRO System, 12-month Lifetime --- ## 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.com.br/products/591474830-waterdrop-c1s-countertop-reverse-osmosis-system](https://www.desertcart.com.br/products/591474830-waterdrop-c1s-countertop-reverse-osmosis-system) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-10-18*
