Returns and the fit guarantee

Last updated October 10, 2026

We're in preview. These terms take effect when we start taking real orders.

Fits, or it's free

We measure every filter by camera before it ships. If yours doesn't fit, tell us within 30 days of delivery. Tap "It didn't fit" on the order in your account, or email hello@caliperair.com with your order number and a photo. We'll send a new one free, and you keep the first.

Changed your mind?

Send back any unopened pack within 30 days of delivery for a full refund to your original payment method. Email us first and we'll tell you where to send it. Return shipping is on you unless we made a mistake.

Damaged in shipping

If a box arrives damaged, send us a photo within 30 days and we'll ship a replacement right away.

Refund timing

Refunds go back to your original payment method within 5 business days of our approval. Your bank may take a few more days to show it.
