The Smart Refill Plan
Fresh refills delivered on repeat — so you’re never caught short, and always at the best price.
Auto-delivered at the best price
We send your genuine FP® refills automatically at the interval you choose — no reordering, and a bigger saving than buying one-off.
We remind you every time
You’ll get a heads-up before every delivery, so you always know when it’s time to swap your filter. Nothing arrives by surprise.
Pause or cancel anytime
Skip a delivery, change how often it arrives, pause or cancel completely — anytime, with no fees and no lock-in.
Which delivery should I choose?
Every plan includes the same amount of refills — just how soon they come to you, depending on your preference. Don’t worry, we always notify you when it’s time to change your refills.
