I have posted this criticism before but I encountered Todd's videos and was quite impressed by them. I then watched his review on water purifiers having done my own research beforehand and while he does end up recommending a decent purifier there is so much more to purification than just what he measures (TDS).

In the end his omission of other factors have led to a conclusion that isn't entirely accurate. (That Zerowater is the best because it filters TDS to 0).

What about bacteria? Other filters that faired poorly in the TDS test focus more on that and then there are a few major brands that weren't even featured.

What about clarify of water? He did touch upon this very briefly but did not go further into it. You would think that a TDS of 0 indicates the water is perfectly clean. This is wrong as TDS cannot measure everything that may be in the water.

There is more to water purification but these are just two examples.

All in all, I have been impressed by Todd's reviews but after watching this review where I actually had done some research into the topic before watching, I came away doubting all his other videos.

What did I miss just because I am not a subject expert in the topic?

I guess at the very least his videos likely eliminate the very worst products but I bet you people are buying whatever products he recommends without thinking about them and may be getting burned or not getting the best product for them.

I have noticed the same issue with Todd's approach. He does a good job of establishing an experimental metric that allows apples-to-apples comparison, but he reviews so many categories of product that there is no way he could be capturing the whole story on all of them. There are a lot of products that won't do well in any "who scores the mostest" contest but strike a good balance of qualities.

Since you already did your research, what is your water purifier recommendation?

Depends on what you want to optimize for.

These are different suggestions based on assumptions of your situation. Assuming you have access to fairly decent tap water (Europe and US) I'd follow Todd's recommendation for Zerowater as thats what I daily drive. I used to rely on Brita but it does not do much...just slightly improve taste and remove the worst heavy metals.

Running tests on my water, there are still traces of some impurities like bacteria and some metals after Zerowater filtering.

I am also about to start testing the Aquatru system that he also recommends.

For Zerowater the filters are quite expensive (15$ per filter) and I have been peeved at how they get used up quickly (I have around 200PPM in my tap water and they last 75-90 days) and still dont filter everything out fully...but subjectively I can't get over how I like the taste and since im not on the west coast im in the more lucky group where Zerowater is good enough. Maybe Todd was also in this situation?

My family does not like it but I love it. It tastes like "flat" water and becomes filled with bubbles if let to sit out for a short time but its worth it because it "feels" so clean.

Sorry if this observation is unscientific but once you have physically removed impurities, you still will have some semblance of subjectivity. I try to target distilled water taste as a point of reference and Zerowater comes close.

I have worked on a system where I first filter out using a Brita filter and then run it through the Zerowater to help improve the results but the problem with this is that my water is not bad enough for the brita's simple activated charcoal to really help reduce so in my case it actually has ended up giving mixed results.

If you lived in the west coast where the water is typically around 400ppm then you'd extend the life of the Zerowater filter quite a bit by doing this trick but for me, well I have to try something else.

But at that point maybe the Aquatru is better which is why I am trying it. For me, the Aquatru is just for curious comparison as this whole journey is reaching nutjob levels for me at this point and im not elon musk levels of rich(these water tests are not cheap)...the Zerowater is good enough for my usage because I live in a suburb away from any industrial places/poorly managed municipality(no major pathogens, just correcting the taste/eliminating any traces of metals and dirt).

In reality, Brita is probably fine but I want that taste of flat water now that I have gotten a craving for it. Every time I drink something else like Brita or bottled water it just tastes weird.

In reality others have told me if one is to spend the dough on Aquatru, you might as well get a under sink reverse osmosis system installed. Takes up less room and is cheaper. I got a good deal on a open box unit so I decided to go that route. Sorry I dont have results yet.

If you are concerned about pathogens that could make you sick, then it becomes tricky. I have traveled to Pakistan and lived in places there where the tap water makes you sick. I have relied on Grayl and based on my testing water and sending it out it seems to filter pathogens but unfortunately it is a massive pain to use. Do not rely on Zerowater/Aquatru for this as it will not help you. I am still in the search for an excellent under sink solution to eliminating pathogens + giving me the taste that I get with Zerowater. My ideal combination would be to have some sort of automatic Grayl + filtered afterwards with Zerowater. Beautiful tasting water but quite expensive. Might as well rely on water bottles at that point. Hope this helps a bit.
