Top Comments of this video!! :3
If this one does just as good you might as well make a fan review channel

Dyson fans are so absurd they cross the line from "creative, innovative design" to "reinvented wheels for people with too much money and not enough sense".

Love this comparison series!! Do more :)

Thank you for this video. I just watched the video from 2 years ago and got to watch this new one after 3 days you realeased it. I just came at the right time. I liked the last comment regarding the value. I agree if you buy two or even more, not 10, but a a few more, one could get a lot of airflow at at a lower speed, hence quieter and more uniform. That if the room is big enough to host more fans.

Laminar vs Turbulent air flow likely the reason the Dyson was able to move more air, further.

Dyson is "easier to clean" because you can't clean the dusty fan and internal pathways. I don't see how this is an advantage.

Good job Mark man!

Thank you for your work. For the money I will get the old style

I just have to say, I love the consistency of the NASA shirt in both review videos! Awesome review! 😆

Great Review!!

Really cool analysis and a great improvement of test measures after the previous one. It puts things on proper perspective of what you get vs what you pay. One observation - you have not measured the watts of more expensive traditional fan. It is more of formality than information, but I would still consider it a good thing to do in a well constructed review and analysis.

I’m wondering what effect directionality and laminar / turbulent flow have on this comparison. Laminar vs turbulent could be a factor - a laminar flow would affect how far away winds travel before succumbing to chaotic environments.
But I haven’t seen anyone mention directionality yet. Consider two light sources: a 15 watt LED lightbulb, and a 15 watt laser. They both produce 15 watts of light, but in very different ways. The lightbulb illuminates everything around it, but that light doesn’t go very far. A laser illuminates just a little dot, but can do so over hundreds, thousands, or hundreds of thousands of feet. In your fan comparison, what happens to the airflow readings if you take one step to the side? Given the Walmart fans have a large, circular design, I suspect that there will be a fall-off of speed, but I’d hypothesize it would be less fall-off than the highly directional Dyson fan. But I haven’t run tests so I don’t know for sure. Which would be the better design then? If you wanted to cool a larger space, maybe Walmart fans would be better, but if you wanted to keep specifically one spot cooler, the Dyson fam would be better?

Thanks for doing this

A few years ago I bought some Vornado fans, and they beat the pants off a couple of other fans I have, both for power efficiency and pushing air across the room. They don't oscillate, but they coooooool!

As the saying goes,
If it ain't broke, don't fix it

I commented on the video 2 years ago, I was still at uni 😂. As I explained before, you are actually moving less air at a reduced speed with the Dyson design ("bladeless"). On your next video, I'd recommend you show a CFD or air flow simulation. The reason why you got more air from the Dyson at a further distance is because it covers a smaller angle therefore is more directional compared to the open fan which has a wider angle thus shorter distance

Good Job…Thank You !

The Navia fan you mentioned is super hard to find, and apparently made in mexico. Couldn't find it on Amazon or Walmart.

It would be interesting to see the power output of the Dyson with the air purifier agains a normal fan and air purifier combo.

If you stand behind a standard fan and speak into it, your voice will sound like a Dalek. I bet the Dyson can't do that.
