Really enjoy your content, but feel you missed two very important topics people question about reverse osmosis (RO) systems: 1. Microorganisms (bacteria, algae, mold, etc.): While reputable RO filters are certified to remove >99% from water, there are some limited studies showing they concentrate within carbon filters (which some of these organisms feed off of, thus end up colonizing). It's common practice for a carbon filter to be used "after" the RO stage, as you describe (see 1:43). Consequently, after a few days/weeks of use, it's believed these filters result in water with substantially higher concentrations than that of the tap water it's filtering. Again, limited studies and theory combine here, so it would be great to hear your take on this. 2. Nanoplastics: Nearly (if not entirely) all residential sold RO membranes are made from plastic. While RO mediums are often certified (depending on the product) by NSF/ANSI standard 401 to significantly reduce microplastic concentrations, there are some studies showing these membranes degrade over time (due to the force of water being pushed through the thin membranes for months before replacement), which results in increased nanoplastic concentrations. It's only in the past couple years or so that scientists have had methods to calculate volumes of nanoplastics, so the NSF/ANSI standards haven't been updated to account for this. Presently, there are a lot of unknowns about the effects of microplastics and nanoplastics, but it has been well established at this point that nanoplastics do bypass the blood brain barrier and have been found in the mitochondria within cells, so there are concerns (which may or may not be legitimate) that nanoplastics could be more dangerous than microplastics. It would be great if you addressed the studies purporting the breakdown rate of RO membranes resulting in nanoplastics in RO'd water. Edited for spelling mistakes and clarity.
@@myaccount0000 Silver definitely helps (folks who use humidifiers often consider adding this for its bacteriostatic properties too), but it doesn't work against all strains. So it stands to reason that it's those unaddressed strains that predominantly multiply. If there are studies breaking down which strains are remaining however, I haven't seen them. Note: This is purely my speculation, but I'd think running the water for a few seconds would help "flush" most of it out of the filter. Probably not enough to discount the concern for there being more than in the source water (unless the source water is really bad), but it should help.
@@myaccount0000 Absolutely, but the bacteriostatic properties don't work against all microorganisms, so it's likely the more resistant strains are what predominantly concentrates within these filters. I would speculate that running the tap for a few seconds would help flush out a lot, but without studies it's hard to say if it would reduce the numbers to that of the source water levels (or better).
Absolutely, but silver's bacteriostatic properties aren't 100% effective either - it's likely the more resistant strains that predominantly concentrate within these filters. I would speculate running the tap for a few seconds would flush a lot out, but studies are needed to determine whether doing so would reduce the volume below that of the source water.
another main concern I heard with RO water is without the minerals, the water itself doesn't get absorbed by the body as much. minerals have a charge that enables the water to move across the cell membrane barrier. could you please make a video on this? thanks.
Just found your channel and videos. Firstly, thank you for putting the time and effort into testing these systems available to the average consumer. It’s incredibly difficult to understand the claims and data provided by these companies in order to decide what system may be right for you. You are truly providing a service and wonderful resource. Secondly, please test the new Rorra system! I keep seeing so many ads and think it is the next “trending” water purification device hitting the market.
I'm glad you found my channel and videos so helpful! Thanks for your feedback, this is what keeps me doing what I do! I do have the new Rorra system on my list! Thanks for your additional request
Thanks for your request! This is a huge project, and I do have it on my to-do list. Many of the gravity filter brands claim their filters can filter thousands of gallons. To give some perspective, I filtered 100 gallons through a few of the most popular systems a couple years ago. It took ~3 months of daily filling and waiting for the filtration to happen to get to just 100 gallons.
I love the RO system I bought based upon your reviews. I'd love to see your review of remineralization filters including the Vitev Remin CA - RO filter!
The Waterdrop King Tank filters performed well in our testing geni.us/BGjAb and British Berkefeld Ultra Sterasyl geni.us/eiAvEH8 has a few official performance certifications
Can you do a video on counter top water filter systems that use little to no plastic? I am worried about micro plastics and forever chemicals leeching into the water.
Thanks for the request, great idea. Currently, most water filters have at least one plastic component, unfortunately. I too hope this changes in the future so we can move away from our dependance on plastic and exposure to MNPs (micro and nanoplastics) No water filter should leach/ expose you to PFAs (forever chemicals) - this is a completely different group of contaminants not related to microplastics. Water filters do not contain PFAs chemcials.
Hey thanks for your request, can you clarify which system specifically you are referring to? We've already tested a couple of Waterdrop under-sink systems: X12 ruclips.net/video/gieWndiEgPE/видео.html G3 ruclips.net/video/Ebm3ZLuEew4/видео.html
Can you review life straw’s new peak straw? I want a portable microplastic filter mouthpiece for bottled water that I end up drinking more than I’d like. (Am addicted to Fiji water’s taste…) Can you please make a video on that topic? Thank you, and I love your channel!
Hey thanks for your request! I do have Lifestraw on my to-do list, though not necessarily to test with filtering bottled water. Interesting idea for a project, I like it!
Can you explain about bacteria colonizing in the filters and also if nanoplastics is shedding from the RO membrane (depending on water pressure) Also, which one better tank or tankless system, and many other issues ...,,,, Hope there is part 2 for this video so you take us through these issues ,, Tons of thanks for your constant work 🙏🙏🙏🙏
Thanks for watching and for the additional requests! Others have asked about the same, and I do think it would be a good idea to do a followup video on these two points. In terms of bacteria/ microorganism growth within the system, this can be avoided by following regular cleaning and sanitization instructions provided by the manufacturer. An additional final stage UV light can also be used for extra protection. I'll be doing a deep dive into the current research on nanoplastics as related to RO systems. I'd hope there are also new and ongoing studies at the academic level to verify this risk. As for tank vs tankless RO systems - this could be another independent video! There are a number of advantages and disadvantages of each, but the key things to look for and compare are efficiency ratio, TDS creep issues, remineralization if it's important, and physical space available for installation vs size of system you're considering
Thanks for all the content. I just wanted to ask, what are your thoughts on APEC Water Systems water filters? I am thinking about buying one of the portable water filters they have, as it is within my budget. Thanks again.
Thanks for watching! I've not tested any of the APEC systems yet, though I do have a few on my to-do list. As of now I don't have any firsthand data to share with you
I've not tested it yet, but it's been on my to-do list for a while. Last I checked, _it did not hold any official performance certifications_ which is a bit of a red flag, but not necessarily a deal breaker
Interesting! If I'm adding my own electrolytes to my water (So basically I don't need to add any minerals) Which would be the best RO system to get? I don't know if I should get an under the sink one, or just a counter top one. I really need help with this and money is also an issue.
If you own your home, I'd definitely recommend an under sink RO system. Countertop RO's are really intended for folks in rental situations who are not able to conduct an invasive installation as is required by the under sink models
@@waterfilterguru Good point, but even If I won my home and have an under the sink RO, If I decide to move in 2 years, can't I just uninstall it and take it with me? Or, is the installation process real hard?
No the installation is not very difficult, it just requires invasive installation - drilling a hole for the faucet in the countertop if there is none, and a hole in the sink drain for the drain line
We have carbon black in our groundwater because of a factory as they don’t care about environment in india… should we use RO or any simple water filter would be okay?
I can't say for certain without looking at lab test data of the water. RO provides the most broad contaminant reduction, and is typically recommended for drinking water. RO systems may require pretreatment to ensure the water falls within their operating parameters

Great information, hopefully people see this.
all (ok at least most, there are bad companies out there probably) those carbon filters are silver impregnated

Safe just add electrolytes
how??
Others have mention this as well, there are plenty of electrolyte packets you can use, like these geni.us/OBxC38v

That's nonsense. The hydrochloric acid and everything else in your stomach will add far more to the water than any palatable water you could drink.
