They'd probably do it no more than ten times.
I just feel bad for all the kids who won't feel the joy of talking into a fan and making a funny voice :(
Chemistry sets, m-80s, model rockets, playgrounds, coaster brakes, whatever kids did before "play dates" and anything intricate with small parts.
I've spent many hours navigating the air purifier market and it is one of the most opaque and customer-unfriendly ones I have ever seen. Beyond the advice given in the article, it's also important to check what the filter exactly is. Some filters are washable, but it often means that they are not as thorough as HEPA filters, which is a big deal if your goal is to avoid the dreaded PM2.5 that are as far as I can tell…

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…

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…
If it makes you sleep better, most household fans are designed to not severe fingers. They use plastic blades (please don't buy household fans with steel blades) which are both light and dull. You might break it but a major cut is highly unlikely.
Where is the fun in that? I say sharpen the blades and make it a real teaching moment.
I have 4 Xiaomi air purifiers at home in Shanghai, during a highly polluted day (pm2.5 > 150), the in door measurement can be maintained link here - https://item.jd.com/5487565.html
I bought an expensive Dyson air purifier for a couple of reasons. It has a remote so I can turn it on from bed. It looks attractive. The sound profile is much different than a box fan for sleeping at night. It can analyze the temperature, humidity, and air quality in real time and turn on if it notices air quality is getting bad. It also oscillates. That said yes it was expensive, but it replaced needing a fan for co…
Compare to your furnace (on fan mode) + air filter ... > It has a remote Check > It looks attractive Check. It's invisible. > sound profile Check. Furnace fans are in the garage. > analyze the temperature, humidity, and air quality Nope. But purpleair will sell it to your for $175. > oscillates Check. Covers entire flat.
Does anybody know if there is a filter or something that increases oxygen concentration in the air? Maybe something that pumps air from the outside and only lets oxygen in?
I’ve seen ads for medical “oxygen concentrators” which involves a face mask. No idea how they work, or what they do.
I don't understand how air purification systems work. I live in a relatively warm climate so windows are at least partly open most of the year. How would an air purifier help me if air keeps flowing in and out the windows?
They’re also useful when you can’t open windows for some reason. Indoor air pollution is generally much higher than outdoor air pollution. Houses concentrate dust, etc.

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?
