How do I know what size filter I need?

It’s easy! If there is a current filter in place, look for the size printed on the sides of the filter. If you don't currently have a filter, just measure the length and width of each return vent. 

If you’re not sure, call us on the Filter Phone at 800-308-1186 and we’ll be happy to walk you through measuring. No worries: If you accidentally order the wrong size, we’ll send you additional filters until the right size shows up at your door. It's all part of our 100% Easy Breathe-y Guarantee
