Do you need to use a dryer or could you hang clothes up to dry instead? Would be free and doesn't damage your clothes as much.

I would sooner invest into a really long, reasonably well insulated hose to hang out the nearest window. If you can manage that sub 3 yards and the hose doesn't dip too much below it's exhaust vent height, I think this solution might beat DIY ice pack dehumidifiers.
I mean, if you can't have the vent go outside, it's better than nothing, but it won't pull a majority out of the vented air without passing over the ice pack multiple times.
Only people I've ever known to try them thought they weren't worth a dime
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.
I don't see how it could condense the very hot damp air from the drier without an active refrigerant loop drawing a fair amount of power. It would also heat up the laundry room like crazy.
Those condenser kits are mostly bullshit.
If you can't vent outside get a heatpump dryer.
They're expensive to buy, cheapest to run.
Maybe if you get a dedicated dehumidifier for the room. I don't see those options doing enough. Dryers output a LOT of water vaper. Especially with heavy loads like towels and sheets. Even then you'd want a continuous draining one otherwise the bucket will just keep filling up.
Not remotely. I had an indoor vented heated dryer and needed a huge dehumidifier running all the time. It actually just evaporated the water inside too, and made it even more humid. It DID catch the lint though, and I feel like the water helped with that.
I would recommend against one that was permanently mounted to the wall, like the one that was linked. Wall mounting is fine, but you're gonna need to give it a good clean every few loads. It's gonna get nasty.
There’s no way I would use this. Buy a ventless dryer.
