Subscription terms

Last updated October 10, 2026

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

Subscribe and save is optional. Here's exactly what you agree to when you choose a subscription.

What you'll be charged

We charge your first box when you check out. After that, we charge the same card for each box when it ships, until you cancel. Every box gets the 10% subscription discount, plus any sales tax.

When you need it. We time each box to your local weather, air and household, so the dates change with the seasons. Each box is priced by how many filters it holds, at the per-filter price shown when you subscribed. Your account always shows your next boxes, their dates and their prices.

Every few months. A box ships every 3, 6 or 12 months, as you picked, at the price shown when you subscribed.

Reminders

We email you a few days before each charge, so you always know what's coming. You choose how many days in your account.

Skip, change, pause or cancel anytime

In your account, you can skip a box, change its date, grade, number of filters or schedule, pause it, or cancel it online in a couple of taps. Changes made before a charge date apply to that charge. There's no fee to cancel, and you can also cancel by emailing hello@caliperair.com.

Price changes

If we ever change the price of your subscription, we'll email you at least 30 days before the new price applies, so you can change or cancel first.

If a payment doesn't go through

We'll email you and pause that delivery until the payment goes through. We try the card on file again each day for three days, and you can update your card anytime in your account.
