I've been using this water filter for a several months. It's compact. The setup was straightforward-no tools or specific skills needed.The taste of the water is biggest win. It's noticeably cleaner, with no chlorine aftertaste or odor. It's great for drinking, cooking, and even making coffee and tea -everything tastes better.Highly recommend if you're looking for an affordable, reliable way to improve your tap water quality! ### ⭐⭐⭐⭐⭐ Easy to install and works great *by P***E on December 16, 2024* I purchased this mainly to supply scale-free water to an opal ice maker. This kit was very easy to install, I only needed to find one threaded adapter for my smaller 3/8 water lines. Everything else was included, and went together easily with no leaks. Very thoughtful design, such as the water inlet/output on top, in a small well, for easy inspection or service. I really like the filter status and TDS lights on the faucet itself - love how integrated and compact the whole thing is. Changing the filter is very easy. Quiet and takes care of itself with auto flush and pump built-in. Would recommend - especially at the price, it is an excellent value. ### ⭐⭐⭐⭐⭐ Price, use, ease of mind *by R***A on December 6, 2024* My wife and I used to buy 8-10 gallons of purified water from the store weekly. The struggle with loading and unloading was too real. Looked into multiple under counter RO water system. Most of the RO systems I was looking at were pricy. I stumbled across this one and had to give it a try for the price. Not only that, the waste water ratio was way lower than the rest too. Set up was a little longer that it said it was, but that's time in a lab. Still was a breeze to get all set up and running. Love the DTS read out on the water spout. Would never go back to buy gallon water jugs again. ## Frequently Bought Together - Reverse Osmosis System with Smart Faucet NSF Certified TDS Reduction, Reinmoson 7 Stage Tankless Reverse Osmosis Water Filter System Under Sink, 400 GPD & 2.5:1 Pure to Drain (RMS-WP-RO400) - 2024 All-New 4 in 1 Tds Meter Digital Water Tester - Accurate and Reliable TDS EC & Temp(Β°C,Β°F) Meter - 0-9990ppm - Professional Testing for Drinking Water, RO/DI System, Aquariums etc --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/562778218-reverse-osmosis-system-with-smart-faucet-nsf-certified-tds-reduction](https://www.desertcart.com.ar/products/562778218-reverse-osmosis-system-with-smart-faucet-nsf-certified-tds-reduction) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-21*
