[@yoshyoka]

This is my field of expertise, so I might be able to clear things up a little. - TDS should not to be considered a measure to determine filter performance, unless the filter is designed only to do that specifically (as the RO or Zero filter). TDS only states how much ionic compounds are dissolved in water, some of which (e.g. Calcium and Magnesium) are actually desirable for taste. - Life straws (either UF membranes or ceramic NF elements) will not withhold dissolved solids, but will retain bacteria, something the other filters will be hopeless at. - The technology of the zero filter is called "mixed bed ion exchange", and a active carbon fleece in as retaining net and chlorine reduction. It will remove all dissolved solids, but has the downside of having a terrible capacity (lifetime is very short). - You can have very good heavy metal reduction and scale protection with cation ion exchange, but you will not reduce TDS. Water will taste slightly saltier. - You can have scale protection and good taste with a little more complex anion decarbonization resins (TDS will still remain the same). - Both a Zero filter and an RO should not be used for bacterial removal: use the life straw for that (or just boil it!). - Gravity fed filters are unfortunately generally a growing ground for bacteria. - Not all activated carbon is born equal; It generally has little influence on TDS, but is great at removing chlorine and complex organic or inorganic molecules. some are specifically cationic active and can remove heavy metals very well. Indeed to test filters properly you are going to need several thousand $ in equipment, the important thing is to select the correct filter for the correct application.

[@Banana_Cognac]

Thank you for the rundown on the filters for the layman. I did feel that the testing done here was too surface-level, and didn't get into what was actually happening. Unfortunately, some people are going to watch this and think the zero will filter out bacteria as well.

[@yoshyoka]

@@Banana_Cognac I agree. Unfortunately water treatment is a complex subject and just giving the basics would require a whole video series. To all people who ask me "which one is the best filter", I can only answer "the best filter.. for what?" as every application will have different requirements. The Zero filter would be the best for your steamer and iron (no residues), yet i would never brew my coffee with it as the taste will be blunt and flat. Similarly there is no reason to use a life straw when you have access to chlorinated municipal water, where a simple AC filter will significantly improve taste ad, if specifically designed for it, take out some heavy metals and chloramines as well.

[@ExZero16]

This is the correct response. Last thing to note is 0 PPM water is not desirable for drinking water. 0 PPM is great for hydroponics but there is a reason there is distilled water and drinking water.

[@ExZero16]

@@yoshyoka Unfortunately, activated carbon will not remove chloramine and most water supplies are using that now as it takes less to have the same effect and does not evaporate out of the water. Depending on the level of chlorine in the water, you can let the water sit for a few days and all the chlorine will evaporate out. Chloramine will stay in the water until directly filtered out or the water is distilled. The science says chloramine in low quality is fine but I know from experience (city water): 1. Kill fish and/or make them very sick. 2. Even using a reverse osmosis system (not designed to remove chloramine), have a huge effect on plant growth in hydroponics. Saw lost of baby plant and slow growth and since filtering out chloramine, I have never lost a plant and massive difference in plant growth and overall quality of the health of the plant (less dead or fading leaves). I only learned about chloramine after posting on reddit about what looked like nutrition deficiencies in my plants and I have a high system that controls the ppm and PH of my hydroponics water. Someone suggested chloramine poisoning as the issue and after getting a filter to remove chloramine, I can say they were 100% correct.

[@yoshyoka]

@@ExZero16 I think there is a bit of confusion here: what you write is correct for Monochloramine; however i was referring to trichloramines, which are responsible for the classic "pool smell" and taste. These can be removed with AC varieties activated at higher temperatures and which achieve higher iodine numbers.

They make extreme claims many times, compared to filters which are actually NSF certified that can't lie about their longevity and abilities. One more thing to note is the TDS for the Sawyer product isnt what it's designed for, you need a bright field biological microscope to test for that.

[@ProblemFactory]

It is very strange that a normal nonRO filter system (ZeroWater) could outperform an RO system (AquaTru) in terms of removing ions, so I did some research online. It seems that ZeroWater is built to remove ions from water using "Ion-exchange resin", which is dedicated for removing ions and usually used as a post processing step for RO system to further refine the purity. ZeroWater does not have RO filter and apply the ion-exchange resin directly. This indeed could result in better TDS values comparing with RO system without ion-exchange resin, however, doing so will drastically reduce the life-span of the filter as the resin is designed for water already has low ion level. Also, because ion-exchange resin does not filter water through physical pores in the filter like RO filter, it could not remove non-ion contaminations from water, such as microbe or organic (carbon-based) contaminants. This makes the "0 TDS" claim more like a marketing strategy as TDS only indicates a portion of possible contaminants in water ignoring many things that are also important like chlorine level, bacterial level, and even added sugar or alcohol in water. For zerowater, combination of different filter components like active carbon could remove many common contaminants and odors but I doubt whether it could achieve the same level of effectiveness over time comparing with an RO system. As its name indicate, while ion-exchange resin removes ions from water, it exchanges the stored H+ and OH- ions (components of water) in the resin with the to be removed ions (so H+ OH- being released to water, bad ions trapped on resin). The H+ OH- storage could be depleted fairly quickly if there are a lot of ions to be removed from water. In fact, on zerowater's website, it claims that each filter can only filter 15-25 gallons of 200-300 TDS water (the tap water used in this video). As comparison, RO systems use tiny pores (1000nm), and virus(>10nm), to allow only water and very low amount of ions to pass through. According to aquatru's website, their RO filter could last two years or 1200 gallons water, which is 30x longer than the zerowater's filter (40 gallons at best). If you are filtering water a lot and try to get as much contaminants removed as possible, I believe the RO system should be both more effectiveness and even cheaper considering the filter cost. If you really want to get the most purified water in home, probably an RO system with ion-exchange resin is the best option. Even distill water is not that pure considering some evaporative contaminants like chlorine are difficult to remove by the distillation process. For this video, I suggest a follow-up video on the measurement of Total Organic Carbon (TOC) for each water sample to get a better idea on the amount of organic contaminants in water.

[@Noadvantage246]

Yeah and there's a HUGE difference between them when it comes to longevity. Zero filters essentially become useless after around 10 gallons whereas RO can easily filter 20x that.

You just solve it by throwing in some pure Celtic sea salt or buy mineral drops. Make your own pure water and turn it in to mineral water. You buy from the market, you're most likely drinking fluoride too. Don't believe major companies.

It would be nice to have seen a breakdown of the cost per gallon of filtered water over the declared life of the filters. I believe the Berkey claims 3,000 gallons per each filter and ZeroWater claims 30 to 50 gallons per filter. There is a big cost difference there for price per gallon.

We live on a small island with no mains water supply, so every house has it's own well or spring. The place we're renting while renovating a 250 year old watermill has an unlined bore and the water quality can be very poor - we can only drink bottled water. Britta filters did nothing for us, removed a tiny bit of smell but thats it. That being said, TDS isnt a very good measure for testing in my opinion, since you need some dissolved minerals to survive - many filters will have media in them to add those essential elements back in, after the carbon and other filter media has stripped them out. Having 0TDS is not good for your health, if that is your only source of water. I really liked the test strips, and have ordered some to play with, it will be interesting to compare our unlined bore hole here with the fully lined modern bore hole over at the mill, while we're waiting for government testing of the water. Overall a great video, but I don't think the test methodology was as robust as your typical tests (which i'm fine with, you be an expert at everything!)

water that hard would strongly recommend you install a whole house filtration system. i have extremely hard water installed an Aquasana Rhino 1,000,000 gallon whole house filtration and it immediately took hardness scale off the chart (above 15 on hardness scale) down to around 2-3. Water softener took care of the rest bringing it to 0. You would never want to use that hard water through faucets, appliances, or other items using water in the house. This will significantly improve water quality throughout the house. It's scary to see what crap the pre-filters pull out before even reaching the resin tank for further filtration. ALL people should be installing these types of systems even if they have slightly hard water.

Thanks for cutting the filters apart at the end. I was curious how the Zero Water was doing so well compared to the more expensive options. Once you cut it open it was clear- the Zero Water uses DI resins to filter the water. This will do a great job at removing just about any impurity from the water, but it will probably deplete itself pretty quickly. DI resins are also more expensive than carbon blocks (generally) so it would be interesting to see the gallons treated per $ spent on the filter. This would be a longer term project which probably wouldnt make for good KZbin though...Entertaining video!

Zero water usually last 20 gallons for me then they start to taste real nasty and turn water more acidic. Zero has charts to determine how long they last with different water supplies. New filters reduce the ph by ~2 from my tap(from a high 7 to almost 5) ive seen replacements anywhere from $2-$8 depending where i bought them.

[@SignorLuigi]

They recommend you replace the filter on the Zero Water units when the ppm exceeds 6. We get about 3 months of use per filter but only use it for making coffee (10 cups per day). So I would estimate about 45 gallons of treated water per filter for our use case (which is well water). The longevity of any filter is going to depend on the quality of the water from your tap. So how long they last will vary widely.

ZeroWater uses the same technology as the other filters like Brita etc. ... so it is impossible to get a zero on this way. Even industrial osmosis water contain a small amount of particles left in the "pure water". So the osmosis system in the test is by far the best system, not by the brand, by the used technology (but therefore it consumes a lot of electricity to do it).

[@R0bsterb0Y]

@POPmMOPm it is physically and chemically impossible to get "zero" reading. Get some information about the filtration technology behind all the "cheap table top" fiters. If you want to change "belief" into "knowledge", send two probes of water (one from the tap and one from the tap filtered by your zero) to a laboratory. And things are allways debateable. You cant proove, that every probe was done by the same method. This all depends on the will to "belief".

[@joecmarques]

This is a great video at illustrating the differences in types of filters, however in terns of determining "the best water filter" it really depends on the goals you are trying to achieve. With that said if you are trying to take pond water or some sort of non-potable water source and make it safe to drink, there are only a few filters in your group that are actually designed to do that (hollow fiber membrane based filters), like the Sawyer, the lifestraw, or survivor filter pro, which will remove all biological contaminates such bacteria and protozoa (but not inclusive of most viruses) which are smaller than the smallest pore size of the filter, although this is not much of a concern in North America. So although you can safely drink scummy pond water and be perfectly safe doing so with the sawyer, it offers ZERO chemical filtration which does absolutely nothing to help with taste or smell. The Zero water filter on the other hand is an ion exchange filter which is designed as a chemical and particulate filter. In other words it uses ion exchange resin to pull dissolved solids out of the water, while also using charcoal to help polish ans improve taste and smell. The end result is that you get zero dissolved solids after filtering which is means it removes most chemicals like chlorine and fluoride and heavy metals and minerals from the water which is great if that's your goal. But can it make pond water safe to drink? Absolutely not, and it's not designed for that either and would be completely inappropriate for that use, just as a Sawyer would be completely inappropriate for use in polishing already potable water. The other filters like Brita and the like that use some form of charcoal filtration are designed merely to polish ans improve taste and smell of water, whilst perhaps removing a tiny amount of dissolved solids and minerals, but are certainly not designed for that. So getting back to the title of this video, "which is the best filter"? It really depends on what you're actually trying to remove from the water, and what you are trying to achieve, and thus would require the proper tool for the job. A killer "all-in-one" filter would combine elements of all these filters and would essentially look something like a Sawyer for initial filtration to take any water you find (like pond water) and make it potable and biologically safe to drink, then you may want to put it through some sort of a charcoal based filter to improve taste and smell, and finally you may want to polish it off by removing any remaining dissolved solids or chemicals from the water by putting it through ion exchange resin based filter like the zero water or alternatively a reverse osmosis system. At the end of all that what you should have is biologically safe water that is chemically pure water, and if you really wanted to you could even run it through a filter that is designed to add back in some dissolved salts and minerals to "improve taste" to something you may be more used to and familiar with. But at the end of the day you can see what we are talking about are vastly different tools that all deal with water in some way, but perform very different jobs. So essentially unless you compare like tools like a bunch of ion exchange filters to one another, or a bunch of hollow fiber membrane filters to one another, what you are really doing is comparing apples to oranges and selecting plums as the "best" tool of then all.

[@Noswalas74]

The ion exchange beads for the ZeroWater will get used up really fast when used this way, the beads change color when they are spent, a few more tests and it looks like you would need a new filter. Ion exchange is typically used after going through a reverse osmosis filter, which typically want a carbon filter before that, and probably a particle filter before the carbon filter, normal people can stop at the reverse osmosis stage, the ion exchange step is usually for lab grade water, NurdRage has a pretty good video on setting up a lab grade water supply, as well as a video on regenerating ion exchange beads.

I like this channel a lot, and most of the conclusions of this video still are likely to be useful, but I see important problems: - The Sawyer and Lifestraw are meant to filter bacteria, not minerals or other impurities. The type of filtration is completely different, and their inclusion in the comparison doesn't make sense. This is my main issue with the video. - The TDS measure doesn't seem too relevant to me either, as several filters use ion-exchange resins, so they will purify your water, without necessarily affecting the ionic strength (they substitute an 'undesirable' ion for a "desirable" or "neutral" one).

[@gregors1422]

Good point. For hiking/backpacking Lifestraw and Sawyer are fine; they'll filter out bacteria and even viruses, but not chemicals (you're not too likely to have toxic chemicals unless you're hiking near old mining activity).

[@zebrin]

@@dromen1 That's a lot of plastic waste. And most of it isn't recyclable I would wager. Most bottled water is just filtered tap water anyways, so getting a water filter will save you a pretty decent chunk of change for roughly the same product. Remember if you do buy to look at the cost of both the initial pitcher cost AND the filters. Because it's kinda like shaving razors. The handle (Or pitcher) are actively cheaper then the heads and filters. Also the lifespan of the filters is pretty important. The Zerowater says that you should replace them every twenty gallons, which isn't very much. But those filters cost about $33 for a two pack from their site. Roughly $16 for 20 gallons, or less than a dollar a gallon is much cheaper than most bottled water not bought in massive bulk.

We developed the product with the aspiration to Help the poorest countries with limited/ no access to clean running water. Our filter came at $4 per unit and the proposal went to most of the multilateral agencies. Yet, they were only interested in products which were produced in their main sponsor countries. We were planning to give the production to each countries... BTW, the biggest issue re water in the world is microbial contamination and arsenic poisoning.

[@allenday2132]

Arsenic in ground water is often bound to iron, and many arsenic removal systems use iron removal technology. My guess is the Zero filter would do good at removing it because the opaque material in the Zero filter is water softener beads. The problem will be how to know when the effectiveness has been reduced. The TDS test may be valid, but high TDS water will "fill" the softener beads quickly. A slightly higher tech filter that can use sodium to remove the collected iron in a back flush system could extend the life by many times. However, the carbon filter element would need to be separated during the backflush.

@UC6fjGuS-TVDUT8u5FS9zwtw Personally, (this is just me and how I'd do it. We have a large pond on our property) I'd strain it first with your coffee filters and then boil it. If you have the funds and resources of ZeroWater already at hand, feel free to use it, but if it's a mountain stream it should be pretty free of solids to begin with (still desperately make sure you boil it). If I were genuinely concerned about run-off or metals or fertilizer etc., I'd distill it at least once. Twice will get rid of most of it. You don't have to have a horrifically complicated still system to just distill water, I've seen folk use a few bottles for small batches. And if you're really desperate and concerned about solids, you could just straight-up boil it and collect the vapor in a towel overhead, wring it into another container and then just bring it to the one-minute rolling boil. Should your municipal water go out, try to fill your bathtub (plug your overflow) with whatever pressure's left in your pipes, and do not flush your toilet (you can use the water in the reservoir). But if you've got access to a spring or mountain stream I'd just make sure to boil it if you're pretty sure there's little run-off from farms or such (and if you're in Appalachia make sure you know where the coal operations nearby are, those're really terribly good at f'n up the entire water table). I hope this helps! Be safe and well :)

You may be comparing apples to Oranges with some of these filters. I think the Sawyer and Lifestraw are water purifiers and the filters is only a secondary concern. Water purifiers use are designed to remove harmful microorganisms like Cryptosporidium and Giardia, some will even remove viruses. Purifiers like the Sawyer use a ceramic element while water filters like the Brita use activated charcoal. Ceramic elements are not as good at filtering out chemicals or the solid particles like while charcoal filters are good at removing chemical contaminants and solid particles, however, they may not remove harmful microorganisms. As for reverse osmosis filters, I have no idea, maybe they could do both.

Most of these do a pretty good/comparable job of removing iron--10fold or more reduction. A helpful comparative calculation would be cost per gallon of each device---both initially (device + filters) and longitudinally (replacement filters.) EDIT: OK so I did my own rough back of the napkin calcs for a few: Zerowater Initial cost $30, filters up to 40 gallons, Cost ~$0.75/gallon. Replacement filters ~$19, so ~$0.50/gallon Brita Initial cost $30, filters up to 40 gallons, Cost ~$0.75/gallon. Replacement filters ~$5, so ~$0.13/gallon Aquatru Initial cost $430, filters up to 1200 gallons, Cost ~$0.35/gallon. Replacement filters ~$90, so ~$0.08/gallon Berkey Initial cost $300, filters up to 6000 gallons, Cost ~$0..05/gallon. Replacement filters ~$150, so ~$0.03/gallon So, while the up front cost seems low for zerowater, and the performance really good, the actual cost per gallon is astronomical over time.

Where is your brain my friend? You just calculated like a robot. There are only 2 proper filters here: Aquatru and ZeroWater, which purify water to a distilled grade. Their performance differences are literally non-existent. At this point, there are only 2 questions to ask: 1) Distilled water isn't good for health? How to make sure the needed minerals and benign bacteria make it back into the water? 2) Costs, as you calculated. (1) above is very professionally solved by Aquatru. One of those filters you see in the vid (#4 filter, green one) does exactly that. They even have microbacterial additive to solve the "pro-biotic"-ness side of things as well. (2) above - the costs - as you calculated, are good. How you managed to compare the quality of something like ZeroWater/Aquatru to Berkey, is beyond me really. P.S.: For God's sake, stop with imperial units, Americans!

[@drsnooz8112]

If I may, you should do a few more of these filter test videos. This vid includes a haphazard assortment of filters ranging from pitcher filters for apartment dwellers, to backcountry filters for extreme backpackers, to zombie apocalypse filters for the prepper crowd. Those are very different use cases and what is acceptable in one use case (eg: operating a cumbersome hand-pump beside an alpine stream) is completely unacceptable in another (operating a hand pump in your kitchen). Moreover, the filters focus on very different water quality problems. Some focus on biological contaminants like bacteria and viruses. Others focus on dissolved minerals. Still others focus on taste and smell, or radiological and chemical residues. And so on. A filter focusing on biological contaminants for backpackers makes no sense for a municipal water supply where everything living was decimated during chemical treatment. Divide the filters into their proper categories and test them head to head with water samples taken from likely sources, like pond or stream water for backpacker filters, ag water for the chemical filters and municipal water for the pitcher filters, etc. You don't have to test for every conceivable contaminant, but a sample of *likely* contaminants from each range (mineral, biological, radiological, chemical) seems appropriate. Finally, reliable lab tests, before and after, are almost mandatory in this case, though your test strips are an acceptable substitute if you explain your methodology and results more. Still, this is a great video. Thanks!

[@WhoDatBoudreaux]

@@ProjectFarm great video! I'd like to add to the comment above and maybe make it a future video suggestion... I agree that the filters tested here cover a very broad set of use cases and may be an apples to oranges comparison. The quick test strips are sufficient for getting an estimate of what's in the water, but kits that use chemical titration are much more accurate. These aren't terribly expensive and you could buy a chlorine, calcium (or general hardness), and iron test kits individually - look for aquarium water test kits. Another useful metric would have been cost of filter per gallon of filtering capacity (estimated from expected numbers provided by manufacturer). In the salt water aquarium groups, there is a lot of consideration given to deionized (DI), reverse osmosis (RO), or distilled water as the starting point before adding sea salt mix. I have experience with high end (low TDS) filtration systems, but there are trade offs that make these less desirable for the refrigerator water pitcher crowd. They may appeal to folks who need a more robust solution for household water used for cooking and drinking... People such as myself, who only have access to well water instead of municipal water. The RO filters I've used require steady 60 PSI water input, reject the majority (to flush/rinse the RO membrane), but provide a steady gallon per day (gpd) output of filtered water with low TDS. That water can then be run through a DI resin bed to drop TDS to zero. Some of these are wasteful by rejecting >50% of the incoming water at the RO membrane. In south Louisiana, I don't have a shortage of underground well water, so the waste didn't bother me. Also, it was set up to fill a large container till a float valve shuts off the source. The major benefit is that they have thousands of gallons of filtering capacity and can be put together for about $100. Costco has a 4 stage filter that takes your household water line (60psi) and runs it through a 4 stage filter process -- 2x Carbon, 1x RO membrane, then 1x DI resin bed (like the zero water filter you showed in the video). This system fills a reservoir tank under your kitchen sink and probably isn't as wasteful as the RO membranes I used in the past. The kit sells at Costco for $150-200. There are other larger systems for household use, but most of them I've seen are thousands of dollars to set up. They filter all the water at the source (well) and usually require a service contract to maintain them... Not worth it for your video or the home owner IMHO.

Now think of a city water or even spring water as a magnet with nails already stuck to it. And then try to pick up that same pile of nails. As most people will know many nails will be left behind. Also is drank exclusively and for long periods, distilled water does such a perfect job of cleaning out one body that it will cure to a large degree and possibly completely any symptoms of arthritis.
