In nature, air plants anchor themselves to trees where they grow without being planted in soil. In our homes, these make interesting display pieces that can be placed or hung wherever you like!
Bright indirect light, mist weekly to increase humidity. 2-3 times a month, give your air plants a soak in room temperature water, preferably filtered or rainwater as tap water can be harsh. Allow to soak for 10-15 minutes (some people like to leave them longer, if your plants are larger they may want more time) then be sure to hang or set down in a way where they can dry off before placing back into their home.
