This space-saving award-winning tankless design takes up less space under the kitchen sink compared to traditional RO units and maximizes water filtration. Filter removes sediment, dirt, and other particles from water In addition, the chlorine taste and odor has also been removed, providing you with a purer, better tasting water for you and your family. Compact, high-performance RO filter and membrane lasts longer than most RO systems and ensures fresh filtered water for 6 months. High visibility filter indicator LED light lets you know when to change your filter for optimal filter performance. Twist and pull release feature provides convenient filter change and quick service Unlike traditional RO systems with bulky storage tanks, the HYDROVOS Tankless RO features a "all-in-one" compact design that saves space under cabinet sink. This RO1600 system comes with all the components you need to easily install the system with regular hand tools. Hydrovos HV-RO1600-OD is designed for household pressure. HYDROVOS recommends installing a pressure regulator valve in front of the system if household pressure exceeds 85psi. Cold water only, do not install on hot water line Review: I originally had the old stage 3 stage reverse osmosis tank system; it did the job but took a lot of space under sink. When my sink rusted through which sparked a mini renovation, I decide to swap it out for a WATERDROP (TSU) tankless water filter. Sadly, the WATERDROP does not remove TDS, therefore the water did not taste as “pure”. Having spent a decent amount of money on the sink, WATERDROP and labor. I stuck with it for the better couple of years to now going back to a RO (tankless) system for better filtration and tasting water. I had originally wanted to go back to WATERDROP, however I found HYDROVOS with an almost 2:1 waste water ratio vs 1:1 of a comparable WATERDROP (and cheaper) I decide to give HYDROVOS a try. For the most part the unit seem fairly easy to install and pretty much “plug and use” if you have an ‘similar’ existing water filter system. However, since my existing WATERDROP is not a RO system I did not have a drain line that need to be tap into the sinks drain. Luckily the process is pretty straight forward and all the hardware are included. Also you will need an existing hole in your counter or sink to mount the included faucet/spigot. Though its not apple to apple comparing my existing WATERDROP TSU to the HYDROVOS RO1400. The HYDROVOS feels a lot better built, it has more weight and the unit feels solid whereas the WATERDROP is slightly ‘flimsy’. The HYDROVOS is also a tad bigger than the WATERDROP but it's still space saving especially when compared to my original tank RO system. The one thing I really like from HYDROVOS is the much higher quality water faucet/spigot. It feels solidly made and larger than the WATERDROP. It also has an ‘aerator’ on the end which neither the WATERDROP or my old RO’s included spigot had. The filter cartridges are a lot larger than the WATERDROP and only require 2 vs 3. I did some calculation and there’s no real dollar saved with having one less filter in my case. But it sure means one less filter replacement throughout the year. A thoughtful after thought is that HYDROVOS included a scannable QR code on the filter which will come in handy when a replacement is needed! The only one minor 'negative' is the packaging seem a little lacking coming in a brown box. However that aside the product is package very securely and even thought it arrived a little banged up the ample packing material protected the unit very well. All in all, the HYDROVOS is a great RO system, it removes TDS and contaminant (as it should) its space saving, tankless and water saving with the 1.9:1 ratio. It’s a solid built unit + spigot while being easy to install with all the hardware included (minus power tools and elbow grease) if you have a fairly similar water filter like in my case. For what you get I recommend it! Review: Per the documentation, it recommends having a certified plumber do the install...and since I had other plumbing work to be completed, I decided to do this with a plumber as well. The documentation is not clear on a number of issues which wouldn't be a problem if they actually had support. I called repeatedly and left voicemails as well as emailed while the plumbers were on site. When I did NOT receive a return phone call for 5 hours while the plumbers were here, I decided it was best to return the unit since it was not working properly. I cannot recommend this unit based on the non-existent support. ## Features - SUPERIOR PERFORMANCE - HYDROVOS RO-1400 reverse osmosis technology physically isolates water molecules from contaminants and channels removed solids and dissolved solids into the drain, leaving fresh and clean drinking water.

It constantly drains waste water and the faucet makes a loud hissing non stop. The only way to fix it is unplugging it. I've emailed the manufacturer about a replacement faucet with no response in weeks. I love how compact it is and definitely filters well but the faucet is a deal breaker. ## Frequently Bought Together - RO1400 Compact Reverse Osmosis System, NSF 372 Certified No Lead, Reduces TDS, Fluoride, PFAS, Efficient 2:1 Pure to Drain, 400GPD Under Sink Tankless RO for Home Drinking Water, USA Tech Support - HV-RO075-FP Water Filters, Replacement Cartridges #1, 2, 4 for HYDROVOS 75 GPD Reverse Osmosis System, Easy DIY Filter Changes, Pack of 3 --- ## 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.vu/products/734703368-hydrovos-tankless-reverse-osmosis-system-400-gpd-nsf-372-certified](https://www.desertcart.vu/products/734703368-hydrovos-tankless-reverse-osmosis-system-400-gpd-nsf-372-certified) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-03*
