I've had the Bluevua ROPOT for a year now and love it. Water tastes great and even better with the remineralization filter. Customer service is also great.

[@boswater6065]

Thanks for sharing!

[@Allaiya.]

This was very helpful. For me, another important thing is I don’t want my water stored in plastic. Especially if it’s being heated in plastic… I don’t think anyone tests for microplastics but it’s obvious a growing concern since they’re everywhere. Aquatru carafe it is.

[@boswater6065]

Glad that you liked it! Yes, testing for microplastics is extremely expensive.

Based on these tests, Bluevua is good as others, and removes the most fluoride. Thank you for testing.

Correct, but remember that we could only test for those contaminants actually present in our water supply. That's why we value NSF certifications so much. And you are welcome!

[@ZorahGold]

Sorry but Bluevue for the win. I've gone through three AquaTru classics in a year plus one carafe, every single one of them defective. As "great" as it may be, doesn't matter if the thing doesn't work. I will say the company stands by the warranty but constantly shipping the system back to wait for a replacement is ridiculous. Everyone I've spoken to who also had (past tense) an AquaTru had similar stories. I've switched to Bluevue and absolutely couldn't be happier. Works beautifully, zero issues, does what it's supposed to do. Those I know who had AquaTru have taken my rec and switched to Bluevue.

[@boswater6065]

Thanks for sharing!

[@Timeka0210]

Thank you for this comment. I've had my aquatru for 2 years, and yesterday, it stopped working. So, of course, I am searching for a replacement. Your comment is very helpful. Thank you for your insight.

[@amazotron3471]

i'm on my second year of BlueVua under very heavy use and have been very happy with it.

[@boswater6065]

Great to hear!

[@phototristan]

My uncles Blue Vua unit died within three months and he complained that he had a hell of a time working with them for any kind of warranty. Both his family and my family have the AquaTru carafe now and are quite happy with them.

[@markandrushchenko6470]

The elephant in the room with AquaTru is they don't recommend using it on the water harder than 10 gpg (or 171 mg/l). Quote from their web-site under the Classic model: Can AquaTru filter hard water? AquaTru is intended for water with hardness below 10 gpg (grain per gallon). If the hardness is higher, lime scale will build up on the membrane RO filter replacement. We do not recommend that AquaTru is used with water in excess of 10 gpg hardness, unless the water is softened prior to filtering in AquaTru, or unless you regularly complete our descaling maintenance.

[@boswater6065]

First of all, you are right that the AquaTru is recommended for a maximum hardness level of 10 gpg. Btw, the same applies to the AquaTru Carafe. But this is not really the elephant in the room in my opinion. I've just checked all 8 other countertop ROs we reviewed as part of this video and none of them even mentions a maximum hardness level - but not because you could use them on any hardness level you want. Hard water will always cause scaling and this will also affect all other countertop ROs. The question is, to what extent? Can they handle more than 10 gpg or less? We don't know. What I know is that both AquaTru units are recommended for a TDS level of up to 1500 mg/L. The Bluevua is recommended for up to 800-1000 mg/L. And Waterdrop C1H, Waterdrop A1, and SimPure Y7P-BW are only recommended for a TDS level of up to 500 mg/L. Now TDS =/ hardness, but calcium does contribute to TDS. Finally, 10 gpg isn't too bad. So, I'm not saying that what you said is wrong - not all at. I just don't think that the other systems are necessarily better in that regard.

[@markandrushchenko6470]

Good point. At the same time, say, I know for a fact my water hardness is well above 10 gpg. So, I know the producer does not recommend this system for my water. And then you read those reports about the leaks. If that happens it's solely my responsibility. And if I buy a different system (1) there's a chance it will work just fine with my water and (2) if something happens there's a warranty. Thanks for the review. I was considering the apec for a while now. But fluoride results seem disappointing. Do you think the Bluevua and its lite version could produce the same quality water? The lite version is way cheaper to buy and to own.

[@boswater6065]

Agreed! I'm not familiar with the light version. But I'd say if it uses the same filter elements, then it should produce similar results. If lite means smaller filter elements, then it may not perform as well.

[@thebooper8988]

There are some reports on Amazon of aquatru's filter clogging after a few months of water that's only a hardness of 6 which really makes the system inconvenient/costly if true. I read one review which had it happen to 3 filters and the customer service, after sending out a replacement that got clogged, told the customer that's as far as their resolution was going to go.

[@boswater6065]

@thebooper8988 From my experience, there are complaints about clogging filters for every single water filter I know. I'm not saying that this isn't valid criticism, but it makes it really hard to find a suitable product.

would be interested to see how much microplastic contamination these RO's leave from the plastic tubes and non-glass water tanks.

[@boswater6065]

Microplastic testing is extremely expensive, unfortunately. We would like to do it at some point in future, though.

[@lourdesfrance5924]

If I'm no mistaken, tap water testing for microplastics costs the same as testing for contaminants - $300

[@boswater6065]

I saw prices much higher than that, but this also depends on how thorough the testing I guess. But let's say it's "only" $300. That would still roughly double our lab costs for each video. So it would be either testing for microplastics or testing for all the other contaminants combined, and we feel that testing for all the other contaminants has priority.

Hi! I'm doing some research and trying to purchase a RO system. I cannot find NSF data for the top filter suggestion AquTru on the NSF website. Are they no longer certified by NSF?

[@boswater6065]

You need to check the IAPMO directory. Here is a link: pld.iapmo.org/ - you need to check "Listed Model / Additional Company" and search for "AquaTru".

[@davidhall8893]

Interested in this as well

[@jmonty0074]

​@boswater6065 They're not directly certified by ANSI/NSF, they are certified by a third party you mentioned to meet NSF standards so your video is misleading (unintentionally perhaps) and unfair to other RO sytems you reviewed that are may also be third party tested.

No, reverse osmosis works without heating the water.

[@MomCheeto4]

Even if the amount of aluminum in the Aqua Tru is low isn't that still a problem if you are drinking it throughout the day, every day?

[@boswater6065]

We didn't test this but I'm assuming that the aluminum leaching, if it really came from the AquaTru Classic/Carafe, subsides eventually. Also, these public health guidelines are usually created taking into account long-term exposure. And please consider that, based on our research, the average American consumes around 10 mg aluminum a day via food, so you would have to drink 52 gallons of AquaTru water a day to reach that amount.

Hello, do these RO systems remove chlorine and lead?

[@boswater6065]

Hi there, chlorine 100%. We couldn't test for lead ourselves because it isn't in our water supply, but both AquaTru units are certified against NSF standards for lead removal (99.1% and 99.2% average reduction). Also, the combination of activated carbon + RO which all of these systems use is highly effective at reducing lead from water.

[@DavidRobinson-s4i]

Does the aquatru carafe work with different carafes?

[@boswater6065]

I don't think so because inserting the carafe into the unit activates the filtration process.

[@tarekal-abboud1501]

Hello, thank you for all the information It’s truly appreciated May I ask if I should use an under-the-sink direct connect filter before adding water to the RO system I’m on city tap water, I usually use a brita only but after looking into it I’m going to order a RO system but was wondering if I use a filter ( like 50 micron or 0.5 micron ) to protect the RO filters or it’s not necessary

[@boswater6065]

These RO systems use a sediment pre-filter before the RO membrane, so it's usually not necessary. But if you know that your city water isn't as reliable then it certainly won't hurt to add another pre-filter.

[@ggarrison1087]

aqua true has all plastic water storage, cant fill water bottles, has no UV or remineralization and is #1?

[@Shadowca3]

Thank you so much for the video! This was the only reliable comparison I could find after tens of hours researching RO filters. I ended up buying the AquaTru from the link you provided. I’m still confused on whether I need to remineralize the purified water after or if it’s safe to drink long term as it is? Thank you again for your thorough work!

[@boswater6065]

Thank you so much for your kind words and for using our link! According to our research, there are only 2 important minerals when it comes to drinking water: Calcium and magnesium. The optimum for calcium seems to be 50 mg/l and for magnesium it's 20-30 mg/l. The minimum recommended levels are 20 mg/l and 10 mg/l respectively. I would assume that after RO filtration your water is pretty much free from minerals, so these are the amounts you'd need to add to reach the minimum/optimum minerals levels. Also, you should be able to find a converter online that allows you to switch from mg/l to oz/gal if needed.

[@vapeking466]

I personally use Swanson's vitamins ionic trace mineral drops as they are identical to and made by concentrace which is considered one of the best for adding minerals to ro water. However far less expensive than any others I could find.

[@boswater6065]

@vapeking466 Thanks for sharing!

[@van123446]

Does any of your units release nano plastic particles from either the housing, tubing, or RO material? thanks. Columbia Univ. with advanced testing techniques have uncovered that many RO systems do release micro and nano sized plastic particles.

[@boswater6065]

That study was focused on nanoplastics in bottled water which we cannot test for. That said, this was only a first step into investigating how nanoplastics may contaminate our water, and it raised more questions than it provided answers. Because if you check the study (www.pnas.org/doi/10.1073/pnas.2300582121 ), you'll find that they identified 7 types of plastic polymers which "can only account for roughly about 10% of the total particles/dots imaged under SRS microscopy" - which is just a fraction obviously. Yes, 1 of those 7 plastic polymers (PA) is commonly used in RO membranes and may originate from them. But 2 other commonly used water treatment methods (ion exchange and coagulation) might be equally affected. Also, the study further says that it is possible that RO membranes actually remove some of the polymers that are abundant in our water. So, again, this raised more questions than it gave answers, like what other types of plastic may be affected? What about the plastics used to construct water filters and their filter cartridges? Maybe the only way to avoid micro/nanoplastics would be to use a water distiller that doesn't use any plastic parts that the water could touch? However, maybe nanoplastics are so small that they would simply evaporate together with the water (could be complete nonsense). Bottom line is, as long as we don't have more answers, we would't demonize RO, especially because chances are that this is a much more widespread problem.

[@mikemihay]

I'm looking at getting the AquaTru Carafe Alkaline - the one with the Alkaline Mineral Boost VOC Filter. What are your thoughts on the Mineral Boost Filter? Versus maybe adding mineral drops to add the minerals back in? Thanks!

[@boswater6065]

Great question. We haven't tested the alkaline version yet. But for all the RO systems with remineraliation that we tested, results weren't that great, meaning not a whole lot of minerals were added back into the water. So mineral drops might be the better option.

[@jsh33]

Amazing video!

[@MarkDickson-dp3ld]

Thank you for this video! Do you have any comments on the cfu (colony-forming units of bacteria) levels in the lab reports? The raw tap water had zero cfu/ml, but the AquaTru Classic had more than 1600 cfu/ml, more than the 500 cfu/ml EPA limit.

[@lalulu14]

Oh dear.... Thank you for pointing that out!

[@boswater6065]

@MarkDickson-dp3ld Great question, and I appreciate the fact that you are asking about this rather than drawing your own conclusions as so many other people do that end up being false. So first of all, you are right with what you say about the total bacteria count in the lab reports. However, what this measurement basically says is that there is - and I'm citing the EPA here - "low disinfectant residual" in the water. In other words, total bacteria count is used to check if a water supply is being properly treated with a disinfectant like chlorine. But because pretty much all water filters remove chlorine and other disinfectants from the water, the total bacteria count goes up - which makes total sense due to low or even no disinfectant residual. That said, these types of bacteria exist literally everywhere in our environment and they are not harmful.

[@johnkap5740]

Great content! Have any of these brands been tested and approved to remove nano and microplastics?

[@boswater6065]

Thank you! If by tested and approved you mean certified against NSF standards, then no. But there doesn't even exist a standard for nanoplastics right now which are usually defined to be smaller than 1 micron in size. As for microplastics, any RO membrane should be able to remove these easily due to the extremely small pore size.

Thanks so much for making this! I recently went down a rabbit hole on a filtration system for my wife's birthday. Ended up getting the Clearly Filtered pitcher, but we are somewhat underwhelmed. I wanted an undercounter system, but price of the unit and of install was pretty high. Is $400 for install appropriate in your opinion? I thought a countertop unit might be best for now. But lack of effortless/affordable remineralization steered me away. I'd love to get your thoughts on if I'm overthinking that? I've heard that the vitamins you get through food are somehow not an entirley sufficient replacement, but don't know if that's legit science.

[@boswater6065]

$400 for installation seems reasonable. As for remineralization, according to the WHO what you should be most concerned about are calcium and magnesium. We always recommend people to at least consider remineralization, so you are not overthinking this imo. I know that the AquaTru can also be used with a remineralization filter. Or you could add those minerals manually with a mineral blend.

[@username00009]

I thought I wanted a remineralization filter, but the water filter article on the Eat Beautiful blog links articles that say adding calcium to water can cause heart disease.

Do you have a video about what happens to the waste water of a countertop RO system that just has one water holding tank. I assume that the RO waste water goes back into the tank. Seems problematic?

[@boswater6065]

The wastewater gets recycles and filtered again. They do this to lower the amount of wastewater that's being produced. This is nothing to worry. What's important is that the water you're drinking is clean, and based on our lab testing we can't see a difference between a system that recycles the wastewater and one that doesn't.

How is the safety of the plastic with the Classic model and does it shed microplastics into the fresh water container? Is the plastic BPA free? We also will be transferring the clean water into a glass carafe to sit in the fridge for cold water!

[@boswater6065]

The Google sheet lists all NSF certifications for contaminant reduction, and it lists several certifications for the AquaTru Classic and the Carafe. It doesn't matter that the NSF certifications were awarded by the IAPMO. IAPMO is fully accredited. About your other questions, we couldn't test for microplastics. The plastic is BPA-free. I think that if you store enough water in a glass carafe or two, then the AquaTru Carafe will provide your family with enough water.

[@markandrushchenko6470]

Hey, Sarah! Can you clarify a few questions for me if you have any time for that? I still can't make my mind up. RO membrane should not let viruses and bacteria through. Does that mean UV light is redundant? If not how bad is it for AquaTru not to have one? What about secondary contamination, what is the AquaTru pure water tank made out of? Why do RO systems need another stage after RO if the RO membrane is so thorough and much better than everything else?

[@boswater6065]

1. RO membrane should not let viruses and bacteria through - true, they are too large in size. But there are several factors that could still cause those pathogens to end up in the filtered water, like a tiny amount of water bypassing the RO membrane. That said, most if not all RO systems for household use are only recommended to be used with potable and microbiologically-safe water. Some use UV light but that is only to stop the water from taking on a bad taste. In other words, if there are any potentially harmful pathogens in your water, please don't use a reverse osmosis system to remove them. Properly disinfect the water first, and then you can filter it using RO. 2. How bad is it for the AquaTru to not have UV light - I wouldn't worry about that at all. Again, this is only to try and make the filtered water taste better for a longer time. But as long as you're not allowing the water to to sit in the tank for too long, this shouldn't be an issue. 3. The website says it's Tritan plastic (BPA-free). But if you're worried about that, you could also use the AquaTru Carafe. 4. I might be wrong about this, but I think that when back in the day there were only tank-based systems, they used a carbon post-filter to refresh the taste of the filtered water after it has been sitting in the tank. So maybe they just kept doing that even with tankless systems. Or some manufacturers might use a post-filter to make sure that there aren't any chemicals from the membrane manufacturing process that could end up in the filtered water. Activated carbon is great for removing those.

Do you know if the APEC ROCT-plus and Waterdrop K19-H are basically the same device? The machine itself, manuals, error codes, and filters seem to be of similar design. Even if similar design, is it possible that the filtering performance could be different depending on individual specifications for the manufacturers? Any additional data about whether other Waterdrop RO systems had dichloromethane issues similar to the Waterdrop A1 and C1H or follow up beyond their statement?

[@boswater6065]

You are right, they look pretty similar, and the filter element looks pretty much identical. That said, we haven't tested the K19-H so far, so I can't say anything about filtration performance. If they use the same filter element, then you can expect similar filtration results, although this also depends on things like water pressure etc. No new data about Waterdrop RO systems yet. And we are currently waiting for an update from Waterdrop.

[@yazars]

@@boswater6065 Thank you! Even though the APEC ROCT-plus costs more than the Waterdrop K19-H, I decided to go with the APEC for a bit of extra reassurance in part because it tested well in your analysis. APEC has a more well established reputation for reverse osmosis compared to Waterdrop, correct?

[@boswater6065]

That's great! Well, if I'm not mistaken APEC has been on the market for much longer. I'm not sure about the well established reputation. But what I know is that both Waterdrop ROs that we tested may have problems with releasing VOCs into the water, and the APEC ROCT-Plus didn't - all based on our lab testing.

[@yazars]

@@boswater6065 Yeah, I'm hoping that the little bit of extra security buying something from a US-based company with a longer history will provide a bit of security in case something breaks while under warranty. Are you all going to publish a standalone review of the APEC ROCT-plus any time soon? I was unable to find much about it in contrast to the Waterdrop K19-H (they seem to be more aggressive in giving review samples to people), so I was thinking about recording an unboxing and setup video so there'd be at least a little more info out there.

When it comes to the AquaTrue Classic, the aluminum section says added (see below). I don't see the results. What does it say for the reduction of aluminum in the test?

[@boswater6065]

We found no aluminum in the feed water and 0.05 ppm in the filtered water. So not ideal as mentioned in the video, but this is a very tiny amount of aluminum and 12 times below the strictest health guideline we could find. Also, the average adult ingests around 10 mg of aluminum a day via food which is much, much more than what you might be exposed to using the AquaTru Classic.

[@Beachlover19-l3z]

The AquaTru Carafe shows a 300% increase in aluminum? Where is the aluminum coming from?

We don't know. Might be coincidence. Also, remember that 300% increase sounds like a lot, but it was from 0.01 mg/L to 0.04 mg/L which is still well below the strictest health goal of 0.6 mg/L set by the OEHHA.

[@boswater6065]

@bbgunn917 An RO membrane definitely has a small enough pore size to reject bacteria and some other types of pathogens, but they might also accumulate and grow in the system over time. Also, just a few germs need to bypass the treatment somehow and you could still get sick. So I'd only use RO as a short-term solution but the go-to methods are boiling and disinfection.

Why are you guys claiming the carafe has the same certifications as the Classic when it's missing the 473 rating?

P473 was for PFOA and PFOS reduction, and that is now part of NSF 53 and NSF 58. So P473 merged into 53/58. And because the AquaTru is certified for PFOA and PFOS reduction, it basically has P473.

[@davidhall8893]

@@boswater6065 isnt the alkalinity of water directly related to it's PH level?

[@boswater6065]

@davidhall8893 I'm not sure about directly related, but the only reason why RO water becomes acidic is because it is so pure (basically no alkalinity) and has a very high affinity to dissolve stuff. And so as it sits it starts to absorb carbon dioxide. Mixed with water the carbon dioxide forms a weak acid called carbonic acid, and this causes the pH decrease. For the rest of my answer I'm quoting an article from aquatell: "Normally a weak acid doesn't affect the pH of a solution because there are many other competing dissolved substances that affect the chemistry. But when even a very small amount of a weak acid is present in almost pure water, the effect on pH can be quite dramatic as we see with RO water. An interesting note about the pH of very high purity solutions is that they are quite unstable. So, even though reverse osmosis water has a relatively low (acidic) pH, as soon as this water encounters another substance - such as your mouth - it will almost immediately take on the pH of that substance."

I was curious about the SimPure results, so I looked up the manual. You state that you ran one gallon of water through each system before taking the water samples. The flushing procedure from SimPure is to go through the outlined steps 3-5 times, which would require at least four gallons of water. I'd be curious to see the lab results after doing a full flush.

[@boswater6065]

No, that's not how we did it. We've installed and primed each system according to the instructions. So we did flush the SimPure 3-5 times. And then we flushed an additional gallon immediately before taking the water sample in order to avoid TDS creep.

So did the aquatru carafe make aluminum rise 200%

[@boswater6065]

The level increased from 0.01 mg/L to 0.04 mg/L - definitely not ideal but this is well below even the strictest health guidelines. Also, the average American diet contains around 10 (7-9) mg aluminum a day. So drinking water at 0.04 mg/L adds such a tiny amount of aluminum that it becomes negligible in our opinion.
