I was surprised to see no mention of energy efficiency. I would consider this an important factor.

If I just wanted to clean the most air as fast as possible; I could set up 5 box fans.

But that wouldn’t be energy efficient. Especially if I just leave them running constantly.

I always thought of Dyson similar to Apple products. Sure you’ll get a more powerful machine for fraction of the price if you get a windows computer, but you’re missing out on the brand and the experience. Most consumer don’t care about cpu speed or memory size, it’s probably similar for the vacuum market. Which company can tell their story more effective that’s where the profit is.

I have tried the box fan + air filter. It's way too noisy and ugly. I ended up just getting a generic tower hepa air filter for a few hundred bucks. I have not tested whether or not it's more effective than the box fan, but it's way quieter and it looks way nicer, and that matters to me.

Plenty of people need to rethink their parenting then. I laugh when my kid falls down. I scream when I saw my kid trying to stick a key into an electrical outlet, and I screamed when I saw my kid trying to put a finger into a vornado fan. Modern fans aren't the same as the box fans we grew up with. And adult would likely walk away with an emergency room bill and a bunch of stiches. A small child would likely lose a f…

I didn't put a key in an electrical outlet, but in Paris when I was a kid I was having trouble sticking the plug in the 220V outlet so I held it tight by the prongs & plugged it in & boy did that feel weird. I never did that again. I never told my parents about it because I would have gotten yelled at. At camp we put crickets on the electric fence, but nothing happened to them, so I grabbed the electric fence, and th…

Wait you went to a summer camp with an electrified fence? Is that common?

I've been taping filters to box fans for decades. Got them running in my home and office 24/7. I put a filter on each side. It's pretty impressive how much they catch.

2-sided is a great idea. It would cut down the noise. Put a washable pre-filter on the intake, and a disposable HEPA filter on the output.

What about fit though, with the homegrown solution? Is that a square foot of tape to fill the gaps? Changing filters looks to be a big taping job.

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

strcpy() has entered the chat.

malloc, free and their little pointers snicker from behind a curtain.

Yep, the Dyson might perform worse in some tests but the box fan is very noisy, and I hate noisy fans... especially for sleeping.

Very common in rural areas. Electric fences are cheap and easy to relocate.

But these are not the lethal electric fences that you see in trashy science fiction movies.

These are specially designed to put out a high voltage pulse which gives a nasty bite, but is basically harmless.
