Be sure to check on the baking soda every once in a while. As it cakes, you’ll need to replace it.
In one bucket, drill holes all along the sides and bottom of the bucket. You’ll need 25 to 30 holes. Set the drilled bucket in the intact bucket; they will be stacked together, but you should have space at the bottom between the two for run-off. Pour in the rock salt. The salt will absorb moisture from the air, which will drip into the bottom bucket. Set the bucket in a room that needs to be dehumidified. You’ll need to place one in each room to dehumidify a home. Check on the buckets at least once a week. You’ll need to pour out the water that collects in the bottom bucket.
Look for products like DampRid or Humydry. To use these products in containers, place mesh netting in a plastic colander. Set it over another container, then leave the containers around your house.

It’s important to use the “auto” setting instead of just the “on” setting. The “on” setting leaves the air blowing all the time, even when the air is not cooling, which means the collected moisture doesn’t have a chance to drain off. The “auto” setting switches off the fan when it’s not cooling, so water can drain to the outside.
Also, remove some plants. If you have too many plants in your house, it can create a jungle-like atmosphere. They can produce a good deal of moisture, especially if you water them too much. Try sticking to just a couple of plants. You can also move them outside or keep them in a single room. [9] X Research source
