While we hope you will measure your vent opening to order the correct size, we do realize mistakes happen.
If you mistakenly purchased the wrong sized Smart Vent size, we will happily exchange it for the correct size within 30 days of purchase. We provide free shipping for exchanges within the United States and Canada.
You can start an exchange at https://flair.co/returns.
Choose the product you need to exchange, select “Sent wrong items” and specify the size you need. Our system will send a shipping label to return the wrong size. Once we receive it, we'll send out the correct size.
Because we love our customers!
