Fans
If you showed a person from the early-1900s a picture of a bladeless fan, they’d think they were looking into a portal. Fans have come a long way from being dangerous contraptions with metal blades and hardly any caging to sleek devices with their fans built into the base.
The greatest benefit of bladeless fans is that they hardly produce any noise. They’re also a lot more compact than traditional upright fans while moving a lot more air per second. And just like coffee makers, certain bladeless fan models let you control their speed and oscillating settings just by tapping on your phone’s screen.
