CripsTaste Tankless Reverse Osmosis System 800GPD High Flow Rate NSF 58&42 Certified & SGS Tested Under Sink Water Filtration System 2.5:1 Pure to Drain RO Water Filter System Under Sink

I recently installed the CripsTaste Tankless Reverse Osmosis System 800GPD in my home, and I’ve been genuinely impressed with its performance so far. As someone who values clean, great-tasting water but doesn’t want a bulky system cluttering up the kitchen, this unit has been a game-changer.First off, the installation was surprisingly straightforward. It took me about 35 minutes to set up, thanks to the clear instructions and compact, tankless design. It fits neatly under my sink, leaving plenty of room for other essentials—definitely a plus compared to older, tank-based RO systems I’ve used in the past. The sleek look also adds a modern touch, which I appreciate.The 800GPD (gallons per day) capacity is a standout feature. It delivers water fast—filling a glass in just a few seconds—which is perfect for my busy household. I’ve noticed no lag or waiting, even during peak use. The 2.5:1 pure-to-drain ratio is another highlight. It’s efficient enough to ease my mind about water waste, which was a concern with some other RO systems I researched. For every 2.5 cups of purified water, only 1 cup goes down the drain, striking a solid balance between eco-friendliness and performance.Water quality? Top-notch. The 7-stage filtration process lives up to its NSF 58&42 certification and SGS testing claims. My tap water used to have a slight metallic taste, but now it’s crisp, clean, and honestly refreshing. The system tackles everything from TDS (total dissolved solids) to heavy metals and chlorine—I even noticed my coffee tastes better. The LED display with real-time TDS monitoring is a handy bonus, letting me see the water quality at a glance and know when it’s time to swap filters.Maintenance seems manageable too. The RO filter lasts up to 2 years, and the PAC filter needs replacing annually, which feels reasonable for the level of purity I’m getting. The auto-flush feature is a nice touch—it keeps sediment from building up, so I’m hopeful it’ll extend the system’s lifespan.There are a couple of minor drawbacks. It’s not whisper-quiet—there’s a low hum during operation—but it’s not disruptive. Also, while the initial cost is an investment, I’m betting it’ll pay off in the long run with its efficiency and durability.Overall, the CripsTaste 800GPD Tankless RO System delivers on its promises: high flow, excellent filtration, and a space-saving design. If you’re after a reliable, modern water purifier for your home, this one’s worth considering. I’d give it a solid 5 out of 5—highly recommended for anyone serious about water quality without the hassle.

Thank you for this product. I am a water specialist and I install RO Systems all the time. this is the third one that I have purchased, and I have loved every one of them. They are very easy to install. The water quality is some of the best I have seen. These units are the best for the money that I have found so fare, and if you are like me and stop drinking water when it tastes bad this is the unit for you. Only advice is when you start the water running watch the Digital meter on the front till it gets down to at least 10-12 and the taste will be amazing. I love how small this unit is. It fits in places that I couldn't get other units into so, functionality and design is the best.

Easy to install and works great. The water taste great

Works amazing. Got rid of rusty well water and tastes just like bottled water. Would recommend to anyone needing better water.

That's too long for water cycle through filters so ppm decrease to nearly zero takes approximately 8-10 seconds; lots of water waste.

I am quite happy with this CrispTaste 700 GPD Tankless RO System so far. Installing wasn't terrible but I don't think it will be done in 30 minutes as the product page states. I do have a lot of experience installing and fixing things but this in particular is something new for me and I have had problems in the past with plumbing fittings from uncommon brands when replacing sinks and faucets, this being no exception.Installation is pretty straight forward, but the instructions certainly are lacking in detail, especially when it comes to operation. They don't thoroughly explain the controls and the lcd panel.I did the easy connections first: waste water line & the output faucet. But when installing the valve to feed the system I had a small leak. So I tightened a tiny bit more and tested, but it wouldn't stop and had to do that several times while getting worse and then I noticed that the valve body was unscrewing from the bottom connection with the 3/8 adapter (not the adapter itself but the pieces that were already factory assembled), and seems that it had an opposing thread and was coming apart as I tightened my connections. Went to 2 home improvement stores to find a better part, to no avail and actually found what I needed on amazon but wouldn't get it until 3 days later. If anyone else runs into this problem, you will need a 3/8 x 3/8 x 3/8 angle stop valve. Included fitting and the package for the one I replaced it with are shown in the photos. The stores I went to only had 3/8 x 3/8 x 1/4. About $15 on amazon.So, the next weekend I attempted to finish the job with the new plastic valve and connect all the water lines to the RO unit. No leaks! I am happy to say. But do make sure you open the side panel and make sure the filters are locked into place before turning on your supply line. Mine must have jiggled loose and I had some water coming out of the unit. Once I got that cleaned up, I flushed for 15+ minutes as it says to do in the instructions while checking all connections for leaks and I am glad there was nothing.Now, it is installed and in use and I am happy to say that I have great tasting water minus many, many contaminants and I can even smell the difference! I'm just worried about finding, as another reviewer stated, replacement filters for this when the time comes. Also, beware the not so touchy touch screen on this. I tried to use the wash mode and couldn't get it to work but accidentally triggered it while slightly moving the unit under my sink. So, a couple things I think need improvement with this: obviously the T fitting, where to get replacement filters, and a more thorough explanation on how to operate the touch screen, wash mode, etc. Overall, though, I am impressed with this product at this price point and looking forward to contaminant free (or highly reduced) water for the time being. At least until the filters need replacement. Good product!

great filter reduced our TDS to zero. water rehydrates as good as kangen water

Received and hubby had it installed in 30 minutes time, longest part was removing the old clunky system. Within 15 minutes, my refrigerator was giving me water again! Have room under the sink and the water tastes plain.
