To help you decide which type of foundation vent cover is best for you, here are some details about the different types of foundation vents and why they are recommended.
Types of Foundation Vents
The most common type of foundation vents that home owners have is the B-vent or smaller size tile-sized tile-shaped vent covers. This size is recommended because it fits in all but the smallest crawl spaces and can still be installed by one person without making any holes in your foundation.

Where Should You Install Vent Covers?
There are two types of crawl space vents: ceiling vents and wall vents.
Crawl space vent covers are installed in the ceiling or wall vent of your home and it is important to install them properly. This helps to filter and collect dust, dirt, bugs, leaves and other debris that enters the house.
