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.
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!
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
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
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

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.
Can you share the resource you are referencing?
Nice video! I cant wait for the lab testing of the other shower filters😂❤
Thanks for watching!
Heads up Mn is manganese... Why do I remember that from high school chem? 5:18
Good catch! My editor highlighted the wrong row, I didn't catch it!
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!
Right on, I'll add this to my list. Thanks for the request!

Electrolytes are usually minerals.

So what's the best undercounter filter that removes things like chlorine fluoride etc also big concern now is drugs in tap water?
Reverse osmosis systems provide the most broad contaminant reduction
Please do a video on the best compact/small under sink options. Thanks!!
Noted! Thanks for your request, I appreciate it

Those negative studies are bogus.

can you test china water filters, those with price below $35.
Thanks for the request, I've got a project like this on my list!
You can eat your minerals ya know...
Yep, as long as we are eating a healthy balanced diet, we get the majority of the minerals we need from food
