Frequently Asked Questions
How do I know what size cover to order?
If you are still not sure, you will need to measure your opening. Always measure the width first, followed by the height. Dimensions are based on the size of the wall or ceiling opening that should be the same as your filter size. For example, a 20×25 filter means the opening should have a width of 20” and a height of 25”.
For vents, order based on the dimensions of your overall unit. If your size is not listed, please email firstname.lastname@example.org to ask about custom sizes.

I’m not sure what layout I should order. What’s the difference?
- If you have an inside layout, the vent cover will fit inside the framework of the box, leaving the outer rim exposed.
- If you have a flush layout, your cover will sit flush with existing box framework, leaving the outer edge exposed along the side.
- If you have a wrap layout, the cover will fit over the top of the existing box framework leaving nothing visible.
