How the filter subscription works

Today — your starter kit. Your Duo Filter+ and first cartridge ship within 24 hours and arrive in 6–8 business days, tracking included.

Every 30 days — your refill. A fresh cartridge is delivered to your door automatically, so filtration never drifts past peak performance. No reminders, no guessing, no rundown — and you're only charged when each cartridge ships.

Flexible — your subscription. Pause, skip a delivery, change your address or cancel anytime, in one click, from the link in your confirmation email. No lock-in, no fees.
