A: It uses an elastic band that holds the pre filter in place around the filter body.

Q: What size filter does it fit?
A: It is listed as 8 x 39 in. Check your filter dimensions against that size before ordering.

Q: How many come in a sale?
A: One pre filter is sold per unit.

Q: Does it replace my main filter?
A: No. It protects the main filter by catching dust first, and the main filter still handles odor control.
