Custom Air Filter FAQs

Frequently Asked Questions

Find answers to the most common questions about ordering custom size air filters.

Enter the actual dimensions of the filter you need, not the nominal size printed on the frame. If your filter measures 19⅞" × 24½" × ¾", enter those exact measurements.

Yes. Our builder supports measurements in ⅛-inch increments so your filter is manufactured to the exact size you enter.

MERV 10 is an excellent everyday choice for most homes. MERV 11 provides additional filtration for homes with pets or mild allergies, while MERV 13 captures even smaller airborne particles for the highest level of residential filtration.

Every custom filter is built to order in our Clearwater, Florida facility. Most orders ship within 48 business hours.

Unlike standard sizes that are manufactured in large production runs, custom filters are built specifically for your order using your exact dimensions. That additional manufacturing process ensures a precise fit for your HVAC system.

Absolutely. Our builder automatically applies quantity pricing, making it more economical to purchase multiple filters at once.

Because every custom filter is manufactured specifically for your order, custom filters cannot be returned unless there is a manufacturing defect or we made an error.
