A dehumidifier should be monitored when used to prevent a fire hazzard.
It is okay to run a dehumidifier and central air at the same time. This will help keep the costs down for the air conditioner. If the dehumidifier is running, the air temperature will cool off quicker and the air conditioner can be turned up a little higher.
You should run it only when it's display tells you the air is humid.
Dehumidifier should be cleaned yearly. Proper maintenance is important for the dehumidifier to work properly. anonymous@oola.com

Only water should be put into a dehumidifier. If you try to add anything else to it, you might end up ruining the dehumidifier.
Some people let their dehumidifiers run for days at a time, but most manufacturers recommend to not run one for longer than 24 hours without at least briefly turning it off.
Get a dehumidifier.
I'd give it 3 days.
After checking out some reviews online the best brand of dehumidifier seems to be Blyss, they are cheap to buy and run, these dehumidifiers can be purchased at all hardware stores.
The dehumidifier would in a sense "win" this battle. Since the dehumidifier sucks water out the air and the humidifier adds water to it. The humidifier would run out of water before the dehumidifier sucks all the water out the air.
