This moisture absorber is perfect for home. I use it for the dining room and living room as there is a lot of moisture and this moisture is really not good for my pains. I find this effective moisture absorber as it absorbs moisture well, as if attracted him. My surprise is that a block absorber is already included in the plastic tray, I did not expect it because it is not specified, then it makes me two block "of humidivore". I find this perfect product. I received everything without breaking, well protected. Now I do not know how long will last the block absorber but what is practical is that you can put in the water tray housing other blocks absorbers of other brands.
