Another idea to increase the humidity in your home is what we see in the picture. I do not know the name of this in English. However, this "box" pour water, hang on a radiator and heat the water evaporates and increases the humidity. It is made of porcelain, so you have to be careful not to break. You can choose different colors and designs that would fit into the room.
If you own an AC in your apartment or home you maybe looking for a free solution that will allow you to remotely control the air conditioning via your cell phone.
