I Bought a Super Cheap Humidifier on Temu

Features#

On the back there’s a power port (USB Type-C) and a power switch. Each press of the switch cycles through the modes: both outlets → right outlet → left outlet → off → and around again. Hold the switch down and the lamp turns on.

The number on the display is probably humidity in %, but it swings around wildly, so I wouldn’t trust it much.

All the humidifying functionality is packed into the lid, so you can just detach the tank and carry it to the kitchen to fill it up. There shouldn’t be any electronics in the tank, so cleaning looks easy too. On this point it might actually be more convenient than my old Muji humidifier, which I used for several years before it broke.

Testing#

Below is the humidity I measured on the day it arrived. The room is about 6 tatami mats (roughly 10 m²).

That day, I hung a wet bath towel at 7:00 and went to bed, then woke up at 13:00 when the package arrived. After that I turned the Temu humidifier on.

In other words, the first hump in the graph shows the effect of the wet bath towel, and the second shows the effect of the Temu humidifier.

The wet towel never got the humidity above 39%, but the Temu humidifier pushed it up to 47%.

Also, a wet towel holds about 400 ml of water at best, while the Temu humidifier takes around 800 ml. One refill lasts 12 hours or more. Not having to refill it all the time is nice, too.

Concerns#

Ultrasonic humidifiers use less power than steam ones, but they come with a bunch of downsides. They also scatter the minerals in your tap water around the room, and if you’re not careful about hygiene, you get mold and whatnot added to the mix.

My room is jam-packed with electronics, so this is really not great, but I decided to write it off as a trial run to find out what life with a humidifier is like. If it turns out that yes, humidifiers are a necessity of life, then I’ll buy a proper steam humidifier from someone like Zojirushi (a major Japanese appliance maker).
