The fan also sucks compared to something like a Vornado. "Buffeting" of air is not a practical issue when using a fan - you want a fan that can create a lot of air flow. The Dyson fan comes across form first then making up reasons to explain the form retroactively. It feels like an interesting look is the goal rather than something that's actually better. Am I wrong about this? Do people that have the fan like it? Is…

We bought a Dyson fan when we had very small children that liked to stick their fingers into moving fan blades. It works really well for that purpose.

Can you elaborate? That episode really worked for me, and fit with my own experience of dishwashers and adding pre wash. My latest machine doesn't have a prewash holder, but does have a prewash cycle on the eco setting - which cleans fine for the majority of my needs - but if things are filthy I through some bicarb in to the machine before I turn it on and it is awesome.

I’m getting ready to hop into some meetings, so here is the short version, I can elaborate more later today. So he only measured cleaning results after the pre wash cycle and not after the full cycle. Obviously you would expect a short wash with soap to be better than a short wash without. And the results there were a lot closer than I would have expected. He completely ignored final results while opining that dishwa…

It's obviously popular to hate on silly-expensive tech, but these quotes were telling for me: > "I think what we're trying to do is pull back a little bit from the CADR metric," he said.

I'm also a little suspicious of relying entirely on the CADR metric. If you're running a filter in an environment that's constantly producing particulates and you need to filter large volumes of air, it seems useful. If you're about to walk into a smoke filled room and have 25 minutes to clean the air first, there's no question that CADR is king. I think it would be interesting to run a purifier in a normal house for…

They’d probably only do it once. It builds character, similar to == in JS or PHP.

Some of the best air filtering systems (and also among the most expensive) are systems like the IQAir [1], which are essentially boxes with a fan at one end and a series of filters arranged in an alternating diagonal pattern: Note: / and \ are each separate filters Filter box ___ | \ | Inflow --> / --> Outflow | \ | | / | ‾‾‾ This maximizes the filtration while reducing the static pressure, since the filtration is di…
