1、养鱼。养鱼自不必说，鱼缸无论大小，都是为居室又增加了一汪水。

2、经常开窗通风换气。总的来说，室外的空气湿度相对要大于室内的空气，可在上午下午开窗换气，改变室内空气流动。

3、使用加湿器。加湿器加湿是室内加湿比较常用的方法之一。但使用加湿器需要定期清理，防止加湿器中的霉菌等细菌随着水雾喷洒到空气中。

4、养绿植。养绿色植物更能督促居室保持适当湿度，尤其是蕨类植物，因为在一定的湿度下它们才可以健康生长，浇水、以及经常用水喷撒叶面这些养护的动作都有利于提高房间内的空气湿度。
而大型绿植，如滴水观音、散尾葵等本身就是一个空气净化器，摆放在居室中，无论是视觉还是体感，都能为家居环境带来清润的气息。

5、增加居室清洁频率。用潮湿墩布擦拭地面，清洁的同时进行加湿，增加清洁频率也就为居室多进行了几次加湿。经常用湿布擦拭家具也能给室内加湿。
