When choosing a vent cover, it is important to consider the types of vents you have in your home. Vent covers for floors are made to fit the opening and to rest in the hole, usually with no means of attachment. On the other hand, a vent cover for a wall or ceiling is designed to attach so that it won't fall out.

There are many different kinds of vent covers. Some are styled like a grate, while others have louvers which can be adjusted to increase or decrease airflow, or to direct air to certain parts of a room.

In addition, the design and detail of a vent cover is important. Now-a-days there are styles ranging from simple to decorative. Basic vent covers are made of metal and come in a many finishes, including white, brass and bronze. You should choose the finish that best matches your home décor because while painting metal vent covers is possible, your finished product won't last long: The paint will chip before the wall or ceiling needs to be repainted.
