The public bathroom air blades drive me crazy. It keeps splashing the water back and forth, the air speed is too high and my hands inadvertently touch the sides and probably there are a bunch of germs circulating inside, as not everyone washes their hands thoroughly.

The old school super blowers that just do hot air down, or whichever direction you turn, probably consume more power, but certainly dry my hands faster and I don't have to worry about touching anything that isn't clean in the process.

Earlier quoted context omitted.

The idea is that the fan is deployed in a closed room and over time, all the air in the room will be circulated through the filter.

But isn't using a fan too long in an enclosed room dangerous? https://en.wikipedia.org/wiki/Fan_death

To the downvoters on wincy's comment: please let's not downvote people for asking questions, or just because you believe they are misinformed -- that's what replies are for.

Yea, it's weird reading this thread to me. I have a cordless Dyson vacuum and it is by far the best home vacuum I have ever used, both in terms of suction power (even compared to non-cordless ones) and in terms of other usability/features.

For a "wired" vaccum, i'll go with Festool every time, but yeah, Dyson wireless vacuum are pretty good.

People are talking about the household vacuum type (upright & cordless) not shop-vacs or dust collectors.

The recommended pick from the Wirecutter is the Coway AP-1512HH Mighty (as of this post, the recommendation was last updated January 15, 2021) [0]. The CADR is available on Coway's product page in what I assume to be imperial units given the units of the other specifications: "233 (Smoke), 246 (Dust), 240 (Pollen)" (under "Specification") [1]. This CADR score puts it just between the BlueAir Blue Pure 211 and GermGua…

We have four in our house and they are workhorses. Still running strong and quiet 3-4 years later of running 24/7. Probably one of the best things I've ever bought. They are also popular enough, and have been around long enough, that there is an "ecosystem" of third party replacement filters that are affordable and capable. The sound of the Coway is also quite nice for sleeping in our opinion. It's a quiet "whoooosh"…

What benefits do you feel from having four filters? Not hating, genuinely curious. It's just never occurred to me to filter the air in my home aside from burning something on the stove or similar

I prefer the Excel XLERATOR hand dryers, and usually spec them over most other models. Hands dry in ~10 seconds, not spashing onto a lower surface, etc.

I always treated my Dyson purifier as a fan that happens to clean the air a little. I leave the real heavy lifting to my Blueair purifiers which my taped up box fan purifiers cannot beat (I measured the 2.5um output during the wildfires).

To be fair, the wildfire situations are pretty much the extreme edege of "acceptable" living conditions.However, these consumer products aren't meant for those extreme conditions. The fact that any filter can handle that is a good testament.

Reminds me of newer appliances (such as washing machines/toilets) that brag about water efficiency yet don't do nearly as good a job, requiring a second cycle, thus using more water.

I still cannot get over this product. They whole selling point of a dyson fan is the 'air multiplier' tech, which creates a low pressure zone that propels air through the ring. According to dyson, this tech can move 15x more air than the fan in the base of the unit. Why in the world would you build an air filter around a system that does not directly interact with 93% of the air it moves? https://www.jameco.com/Jamec…

Dyson fans produce a continuous stream of air. Regular fans produce choppy air. I don't think anyone actually notices this effect until you point it out though.

I hated the vacuums (the one I bought was way too heavy, loud, expensive for what it did) and air blades, but love the fanless ventilators. It’s light, cute, easy to move, with no visible moving parts, is still surviving spotlessly. I wish there was better competitors.
