Do dryer "condenser" kits work well enough? (www.aliexpress.us)

There are kits like this sold online, the one linked, specifically type 4 with a drawer, work as follows.

Put about 1-2 cm of water in, optional an icepack.
Run your dryer.
At the end of the cycle, dump the collected condensed water, optionally swapping the ice pack.

Do these work well enough to dehumidify dryer output in a rental environment?

Edit 1: For those recommending me to buy a ventless / condenser / heat pump dryer.

Feel free to send me $50-100 each, as I cannot afford one.

Do note, I do have a vent near where my dryer is, it is just very loud. Thus why I was thinking of supplementing it with this.

I have zero experience with these things (never even heard of them), but if you’re talking about some sort of passive system designed to condense water vapor out of conventional dryer exhaust, there’s no way something relying on an ice pack is going to make a meaningful dent in the water content of that air.

Dryer vent air can be about 120F at ~20% relative humidity (per a Google search). Looking at the psychrometric chart on engineeringtoolbox.com, if you were to cool that air down to 70F, it would be at 100% relative humidity (otherwise known as the dew point), meaning you wouldn’t have removed any moisture from the air…

Practically speaking, you’d basically just be massively increasing the humidity in your space… eventually it would likely condense on any surfaces in your home and increase the likelihood of mold growth.
