It's night and day. But note of caution, once you get used to drinking RO, it sort of ruins drinking other water.
Agreed. I don't have RO, but I have a distiller. Same thing, once you there you can't go back.

Tankless RO is not intended for residential use, where one would dispense relatively small amounts of water frequently. Search for "TDS creep". Basically, when the system is idle, ions will remigrate into the filtered water that resides in the system, so the quality of water that comes out from the faucet initially (this is what you are most likely to drink) is the worst quality water that you would get, with a few hundreds TDS reading. A way around is to dispose of a few cups of water when you dispense water (EVERYTIME, especially after idled for overnight), then store the water after in a jar. This is not practical thus I do not think that tankless systems are intended for residential use. The TDS meter embedded in this system is misleading. I would suggest to buy a meter and test it yourself - I did and returned the system.

Our family drank RO without reeintroducing of minerals for a while and we realized our hair falls like crazy and skin was super dry. Stopped and everything goes back to normal.

I have a Samsung fridge bought in 2011 hooked up to RO running for the past 9 years without any problems. No bypassing or disconnecting the built in filter at all.
The samsung fridges I happened to get my hands on are quite forgiving. I had mine hooked up to Watts premier RO and never has any issue as well. I did check inlet pressure tho. Not all RO systems are made the same. Follow the manuals is never a bad thing.

Quote from obergm :
Reverse osmosis water wastes a lot of water flushing our the membranes. It also depletes your body of minerals and makes you more thirsty than the same filter without the RO.

Unless you are trying to purify non-potable water it's unnecessary.

A simple multi stage filter gets the bad stuff in city water out and leaves the minerals in. Doesn't waste water down the drain either.
Please stop spreading the myth that RO water depletes your body of minerals, this is totally absurd. Most of our daily mineral intake comes from our food, not water. Did you try to boil your tap water until it totally dries up to see how much minerals is left? If you do, you'll realize that there is just a tiny bit of minerals left and is totally insignificant and will not have any impact to our body.

Just my 2 cents. I'm a "water snob" My parents had RO growing up and I can't stand the taste of tap water and must have pure RO or bottled. I've had RO in my own house for 25 years. I'm on city water. It's clean. I see the reports.

Besides the taste, the other reason I believe in RO water is whenever I change the filters, they are nasty dirty with a rust colored, gross film that otherwise would have been drank. I change the filters every year and the membrane every 2 years. I must have a water leak sensor near the unit though because these are notorious for developing leaks. Twice I've had leaks and thankfully they were small and were caught with the sensor quickly. They developed years after I had these installed so I would also say these should be replaced about every 5 years or so.

Quote from jemhunter :
I got this unit for the same price during prime day. While doing my research, reading various websites, there were few claims that I find inaccurate and must be some marketing BS.

1) hook up is much easier. FALSE! There are still as many tubes and connections that need to be made. Just the connection to the tank is now gone. So barely simpler at best.
2) better water quality. FALSE. About the same as my old unit. By quality, I mean TDS level as that's the only way to measure. The water does not taste as good as my old unit but that is subjective and I got used to the new taste after two weeks.

Couple of things to watch out for:

1) make sure an electrical outlet is nearby. It has an internal pump to push water to its faucet. Models with a tank don't need electricity to run. That also means you can't get filtered water during power outages.
2) replacement filters are expensive. I am mean darn expensive.

I don't regret my purchase. I had one with a tank that was a pain in the neck to replace the filters. It's much easier with this. This is the main deciding factor as I don't feel like crawling under the sink with my bad back.
FYI Watts makes tanked systems where the filters that come out with a push of a button.

Waste rate is 1:1, compared to traditional tank unit 3:1
This system has a pump. A tank system with a permeate pump will have a more efficient rate similar to this system. As a bonus a permeate pump doesn't require electricity.

So much mis-information about this RO system, so I will attempt to clear up a few things. First, I have been using this filter for 6 months and it's going strong, and have used a 6 stage iSpring tank RO filter for 5 years before that, so my comments came from my experience with the filter.

1. Installation is much easier than the usual tank RO, I'd say 3x faster, and a lot less prone to leaking due to less connections to make.
2. dispensing speed is at least 2x slower than tank RO, about 1 tbsp of water comes out then pause for 2 seconds, then continuous stream of water comes out. I lose patience most of the time and only fill half of my drinking cup. This is its worst weakness and my biggest issue with it.
3. The trade off for slow speed is supposedly cleaner water which doesn't sit and collect in a tank for ages. This seems believable, but I would have no idea how dirty the RO Tank usually is.
4. Water tastes just like tank RO or my Bosch fridge water
5. Definitely more compact thank a tank RO, maybe 1/3 to 1/4 of the space required
6. Requires an outlet
7. cost a lot more to purchase and the filters are also more expensive. mine is still good so far. wastes less water than tank RO.
8. For those who like mineral taste, a new addon filter should be coming soon (likely in months) to reintroduce minerals back into the water (likely equivalent of stage 7 of tank RO). I know this because they are sending me one for testing. If you tell them you're interested on amazon or their website they may consider sending you one.
9. TDS display is fairly accurate, mine is around 19. my own meter usually shows 21.

Overall I would still recommend this RO system over the usual tank RO, mostly due to compact size, much nicer looking even under the sink, and easier to install. If dispensing speed or budget is your concern, I'd get a Tank RO instead.

The only selling point I see is less footprint under the sink and leak detection.

The rest are gimmick and dubious marketing.

https://www.waterdropfilter.com/p...ion-system
  • TDS is a gimmick. You're not going to open the cabinet every pour to check the TDS reading. TDS meters are cheap.
  • Permeate pump on a R/O can bring waste/finished product to about 1:1 and does not use electricity.
  • 400GPD is a marketing gimmick to hide the horrible flow rate of 0.27GPM. If you run this 24 hours you only get 388GPD and no household is going to consume that many gallons per day. That's why traditional R/O is adequate between 50-75 GPD for most people. Home Master flow rate is 0.8GPM at the faucet with house water pressure @ 55psi.

Quote from gzrecoil :
I'm researching RO systems myself, I'll take a comprehensive stab at it based on what I know from my research(I encourage you to do your own).

To preface this, remember, a lot people are totally fine with the flavor or municipal water and don't use filters at all. Brita filters remove some metals, organic compounds, and chemicals which change the FLAVOR of tap water. Brita is only meant to improve the flavor and that is truly enough for most people. Is your municipal water good? Most is. Your local water provider/municipality provides yearly reports. Look into it! Pur takes it a step further and removes some additional items, which based on your water quality report you may want/need to filter out these chemicals etc. I believe both companies also offer special filters for lead heavy water, again, very specific to each area.

Okay, you've looked at the yearly report. You probably find no deficiencies, GREAT! You probably don't need RO but might still WANT RO. Why? A few reasons. RO water tastes WAY better to some people, including me.

This system here does NOT re-introduce minerals. What does that mean? It takes beneficial minerals out that are good for you, balance the PH of water, and give the water a "good"(debatable) flavor. Some people like unmineralized taste, some don't. For cooking and other applications like fish tanks, you want or need PH balanced water. In this case you want a six stage system or a model that re-introduces minerals. Most six stage systems only reintroduce calcium to balance PH. I'm okay with that for now but down the line I may look into systems that reintroduce more minerals if it is deemed necessary or desirable.

Why else would you want RO? Water providers and the people working there aren't perfect. Machines break (I'm sure you've seen boil advisories), and people make mistakes. For example, my water provider in 2019 saw an event that was not reported to the public in which one chemical was released into the system at levels way higher than allowed by law. In 2020, a pipeline contractor dumped thousands of gallons of undisclosed chemicals into the reservoir by accident. I imagine most were filtered out but we don't know until we get the water quality report. Even more, if the chemicals, organic compounds, and metals are within the accepted range, you can still filter them more. I would argue that many of the things RO removes in addition to what municipal water provides are undesirable. However, you might never notice if you don't have a skin condition that is reactive to these chemicals and based on regulations it's totally unnecessary.

Finally, there's also 7 stage systems. This introduces also a uvlight to protect against bacteria. Very unlikely you'll need it, but it's an option and what I'd consider "the best". But I think this is more geared towards well water.

This unit is arguably no better than the G2 also on sale for $225. They're both tankless, they both waste one gallon of water for every gallon they filter, they both filter 400 gallons per day, this one the extra water quality readout which allegedly isn't a useful indicator of quality, and is self cleaning. The benefits of these systems are that they are tankless and compact. I.e. you might be able to fit it under your sink instead of putting it in the basement and running the lines upstairs. Maybe you can't fit it under your sink though... If you can't, and maybe even if you can, I would look elsewhere. Hopefully this doesn't get deleted because I believe these are sponsored posts.

I personally landed on the APEC ROES-PH75 for $230 and bought three sets of extra main four filters which get replaced every 6-12 months so after two years I can evaluate if the other three need to get replaced (2-4 years) . They only waste 1/2 gallon per gallon instead of 1 gallon per gallon this unit does, use standard filters, and are made in the USA. The downside is they are much larger and require a tank. I imagine the filters for this unit being non-standard are also drastically more expensive. This likely means you can get the already filter water from the tank much quicker than the tankless, but the unit is only 75 gallons per day vs 400and will take longer to fill up. If you need large quantities of RO water on demand I don't think either of these systems fit your needs. The APEC ROES-PHUV75 has remineralization AND UV. Both cost extra $$$. APEC offers a unit comparable to this slickdeal for $199 at all major home improvement retailers which is larger, requires a tank, but has standard filters. The website I found APEC through isn't charging tax and is having big sales plus free shipping with the code in the banner right now. Feel free to PM me if you have more questions! If you have any corrections to my post I'm happy to edit it, and if you have any systems recommendations before I pull the trigger, that is very much appreciated.
I am also considering APEC system, however, RO-PH90 system is a six stage system that I am interested in and when I called apec to inquire about it they said this system "adds minerals back to the water". Is that true? Do you have any knowledge on this system?

Has anyone considered or have a whole house filter system as well? If yes, which ones do you recommend? I am thinking of whole house filter too because the water that we get is very hard, it leaves white powdery deposits on our facets and shower heads and if I drink that filtered from the fridge, I feel very heavy after drinking that water. So considering RO for kitchen sink to drink and cook from and whole house carbon filter system for showers laundry etc.

Yes. The 6th stage is a adds calcium carbonate before sending it to tap/ice maker.

You may also want to consider Home Master's competitor to RO-PH90 because this comes with a permeate pump (no electricity needed) which reduces waste water. Home Depot return is 180 days.

RO-PH90 also available at Home Depot - https://www.homedepot.com/p/APEC-...435?NCNI-5

You need a water softener/conditioner if you don't want hard water for rest of the house. Otherwise R/O will treat hard water.
