If you ever need assistance or a replacement they never hesitate to help you and will resolve the issue quickly, efficiently and without costing the customer more time and money. I have been using their filters for 2 years now and have felt so heard as a customer. They really care about their customers.
Never buy this filter twice.
While you're subscribed, the hardware is our responsibility, not yours. If a valve sticks or a housing cracks — in year two or year ten — we send the part free.
- Lifetime hardware warranty while subscribed
- Free replacement parts, self-served from your account
- Price locked at what you signed up for
- Cancel anytime — no lock-in, no exit hoops
Questions, answered
When am I charged?
Once a year, on the day you subscribed — and we email you 14 days before it happens. No monthly charges, ever.
Can I skip a year, or cancel?
Both, in one click from your account. Skip if you've got refills left over; cancel anytime with nothing owing. Skipping is fine — we'd rather you skip than bin spare refills.
What ships each year?
Year one: your filter plus a full year of refills, free shipping. Every year after: your refills for the year in one box.
What does the lifetime warranty cover?
The hardware — valves, housings, fittings — for as long as you're subscribed. Parts ship free, self-served from your account, no receipts or arguments.
