I love the sleek tankless design — it saves so much space under the sink and looks modern and organized. Installation was straightforward, and the smart faucet display is a really nice touch for monitoring filter life and water quality. The system runs quietly, and I’ve noticed a huge improvement in both drinking water taste and cooking quality. Review: This is a top notch system and top notch company - I RARELY give anything 5 stars so it should not be taken lightly. but, this unit, the company and they're attention to service has left me totally impressed. I've had 3 previous RO units and every last one of them has left me disappointed. Some more than others but they've not been replaced because they wore out. They were hard to care for, performed poorly, Name it something left me not happy. So much so I'd actually given up on RO units and went with a simple multi-stage water filter. Which was "ok". Until this unit. For the record I also purchased one accessory for it (their small pressure tank https://www.desertcart.com/dp/B09MD7FFYP?ref=ppx_yo2ov_dt_b_fed_asin_title This because I have the unit hooked up to my refrigerator which has an ice maker so the pressure tank was necessary so when the ice maker called for water there would be sufficient flow to maintain correct operation. Neither unit has disappointed me (except a little stand for the tank would have been nice to have). As it is I've worked around that oversight. By being a "tankless" system there is no problems with stale tasting water and being a very small tank water is exchanged in it almost immediately while it does it's job. The main unit sits under my sink, and when filling a container of say a half liter or more the pump will kick on and hum quietly under the sink. Almost unnoticeable. The water taste is great, the remineralization gives me just the right amount of TDS back into the water for taste and mineral content. Bottom line this is one helluva nice unit Also wanted to add how incredibly attentive people in Customer Service have been especially Olivia. Honestly once again a top notch unit and company. If not this one grab a unit from these folks I don't think you will go wrong here. Update 11/17/2025 I am becoming increasingly concerned and disillusioned here with this product and the Waterdrop company. About 2 weeks ago I began noting quite high readings of TDS in my water unless I let this system run an inordinate amount of time before consuming or testing. Which is impractical as the unit is not simply plumbed to my sink but additionally plumbed to my refrigerator dispenser and ice maker. Here it is totally impractical (if not impossible) to allow this system to "run and flush itself) every few hours! I don't know if something has failed (they claim the CF type filter is supposed to last 6 months and the RO cartridge 12 months). Well I am not even at 4 months of use yet and I am using this with softened pre-filtered water. Yet trying to get a hold of someone at Waterdrop is like pulling teeth! I am seriously considering disposing of this system and either A going back to a conventional (tank type) RO system or perhaps one from a company with better follow through. As this is unacceptable. Should this change or be resolved I will certainly follow up with a full report. For now consider this a 2 start item not a 5 star Update on an update Upon talking further with the company re the concern(s) I have had/experienced, especially with Krystal, then verifying it with independent research on my own, I've discovered what was a "concern" is actually just a phenomena with all RO systems (whether tank or tankless as this one). It's called "TDS Creep". So what had me concerned was when left overnight, if you drew a glass of water and tested it straight off with another TDS meter it would give a somewhat high reading. Not awful just higher than you'd think. I've since come to find out this happens with all RO systems due to the stagnant water sitting under pressure against the RO Membrane. And that initial "slug" of water does flush away in seconds. Krystal was quite helpful in helping me discern this. I think some of my concern came due to some language differences as well as the huge time difference with their tech support. No there is not only a lag but with things translated "on the fly" there can be some misinterpretation. However they have been more than kind with walking me through the whole thing and having the knowledge will keep me from making a poor decision. I like the system so much a I ended up buying a second one for our daughter and will install it soon. For her I found a G2 and am looking forward to getting it installed ## Features - [8-Stage precise filtration] Tested by SGS, the reverse osmosis system features an advanced 8-stage filtration process that reduces harmful contaminants such as PFOA, PFOS, chlorine, bad taste and odor, lead, fluoride, heavy metals, and other impurities.

Overall, I am pleased with this RO system. Sort of easy to install and the water flows and does not run out like my old tank RO. The instructions were easy to follow and I like how much smaller this tankless RO system is compared to my old tanked RO system. Great value compared to other company tankless RO system. Right now I am flushing my system but the water had low TDS even before flushing. The only bad things was the tube is bigger than my previous RO system so I had to use the included faucet which my wife hates since it is not gold. I checked the Waterdeep website but there is no gold nor black faucet I can change. The tubing was a tad inflexible but I was able to install them. Once the flush is done, I expect the water to have a clean taste with no odor. ## Frequently Bought Together - Waterdrop G5P700A Alkaline Mineral pH+ Reverse Osmosis Water Filter, NSF/ANSI 372 Certified, 700G Reverse Osmosis System, 8 Stage RO Water Filtration System, 2:1 Pure to Drain, Smart LED Faucet - Waterdrop WD-G5P700A-CF Filter, Replacement for WD-G5P700A Undersink Reverse Osmosis System, 6-month Lifetime - Waterdrop WD-G5P700-RO Filter, Replacement for WD-G5P700 & WD-G5P700A Undersink Reverse Osmosis System, 24-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.jp/products/717706186-waterdrop-g5p700a-alkaline-mineral-reverse-osmosis-water-filter-700-gpd](https://www.desertcart.jp/products/717706186-waterdrop-g5p700a-alkaline-mineral-reverse-osmosis-water-filter-700-gpd) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-05*
