What size bag do I need?
If your central vacuum unit is shorter than 34 inches tall, then you will need to purchase the #720H-5 paper bags. However, if your central vacuum unit is 34 inches or taller, then you will need to purchase the #721H-5 paper bags.

What about the cloth bag and filters?
Replace a new blue cloth bag, supporting the paper bag if desired. Below the bag are two green mesh and one foam filter (in older units). Replace mesh filters with a single #740 mesh filter if needed.
