HYDROVOS 400G Compact Reverse Osmosis System, NSF 372 Certified No Lead, Reduces TDS, Fluoride, PFAS, Efficient 2:1 Pure to Drain, Under Sink Tankless RO for Kitchen Drinking Water, USA Tech Support

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!

Updated ReviewThe system itself works well, and my water now tastes great! I’m also happy to report that I am getting ice from my fridge, even though the plumber initially told me I’d need a special pump for that. So that was a pleasant surprise.However, I’m still very disappointed with the company's lack of customer support. When I ran into installation issues and called for help, I only reached a voicemail and never got a response. That added a lot of unnecessary stress during the setup process.I ended up hiring a plumber who told me the system wasn’t compatible with my fridge’s ice maker. Without proper support from the company, I was left confused and frustrated. I considered returning the system at one point because I thought it wouldn’t meet my needs.The product is solid, but the customer service experience has been very discouraging. Quick and responsive support would have made a big difference. This is why I am giving it a 4 star instead of 5.

I recently installed Hydrovos reverse osmosis system that has completely transformed the quality of the drinking water in my home. If you’re looking for the purest, cleanest water for your family, this system is an excellent choice.One of the standout features of this system is its compact design. It fits neatly under my sink, taking up minimal space, which is perfect for those with smaller kitchens or limited cabinet space. Despite its compact size, it doesn’t compromise on performance.While there is a bit of vibration noise when the system is in use, it’s relatively quiet compared to other systems I’ve heard. The slight hum is a small trade-off for the efficiency and effectiveness of this unit. It’s incredibly satisfying to know that the water coming out of my tap is of the highest quality.Installation was straightforward and didn’t require any professional help. The instructions were clear, making it a hassle-free process. I managed to set it up in a short time, which was a pleasant surprise.Overall, I highly recommend Hydrovos reverse osmosis system, especially for moms and families committed to clean living. The peace of mind that comes with providing the best drinking water for my family is priceless. If you’re in the market for an efficient, space-saving, and effective water purification system, this one is a top contender.

The media could not be loaded. Just installed and tested the water. To compare, the PUR Plus filtered water is reading at around 400 TDS and the Hydrovos 1600 is reading around 40-60 TDS. Also the installation was very seemless. I purchased the mini tank as well for the fridge line. I will add the line to the fridge another day, but I have already installed the mini tank and it was pretty easy.

It’s not suitable for the faucet I purchased which was more than the water system it’s not compatible. Very frustrating and disappointing that this happened. Don’t buy this product it’s a mess

Very good filter

Let's talk filters. We installed about 5 months ago and started getting the alarms for replacement of the first 2 filters. We use the unit daily and approximate 1 gallon per day so at most 200-300 gallons. Seems like a short schedule for filter change. I suspect reminder vs actual usage tracking.

It was first time using this filter. It was very easy to install. Need same color lines to be labeled ( this will help better & quick understanding). I love it.
